serving gas supplier and the local building, heating, plumb-
ing, or other codes in effect in the area in which the installa-
tion is made. In the absence of local codes, the installation
must conform with the National Fuel Gas Code, ANSI
Z223.1.1988.
This furnace is designed for a minimum continuous return
air temperature of 60 degrees F DB or intermittent opera-
tion down to 55 degrees F DB such as when used with a
thermostat night setback. Return air temperature must not
exceed a maximum of 85 degrees F DB.

I. LOCATION
A. General
4t CAUTION: Do not install furnace in a corrosive or
contaminated atmosphere. Make sure all combustion
and circulating air requirements are followed, in addi-
tion to all local codes and ordinances. -
' Do not use this furnace during construction when adhe -
' sives, sealers, and/or new carpets are being installed. If
=the furnace is required during construction, use clean
outside air for combustion and ventilation. Compounds
of chlorine and fluorine when burned with combustion
air form acids which will cause corrosion of the heat
exchangers and metal vent system. Some of those com-
pounds are found in paneling and dry: wall adhesives,
paints, thinners, masonry cleaning materials, and many
other solvents . commonly used in the construction
.. process,
Locate the furnace close to the chimney /vent and as near
the center of the air distribution system as possible. The
furnace should be installed as level as possible.
When a furnace is installed so that the supply ducts carry
air to areas outside the space containing the furnace, the
return air must also be handled by a duct(s) sealed to the
—2—
TABLE II— DIMENSIONS (In Inches)
furnace casing and terminating outside the space containing
the furnace.
Provide ample space for servicing and cleaning. Always
comply with the minimum fire protection clearances shown
on the unit rating plate. This furnace shall not be installed
directly on carpeting, tile, or any combustible material other
than wood flooring. The furnace may be installed on com-
bustible flooring when installed with the accessory down -
flow subbase, which is available from your Distributor or
Branch when required.
B. Location With Respect to Cooling Equipment
The cooling coil must be installed parallel with, or on the
downstream side of, the furnace to avoid condensation in
the heat exchangers. When installed parallel with a furnace,
dampers or other means used to control the flow of air must
prevent chilled air from entering the unit. If the dampers
are manually operated, they must be equipped with means
to prevent operation of either unit unless the damper is in
the full-heat or full -cool position.
C. Hazardous Locations
When the furnace is installed in a residential garage, it. must
be installed so that the burners and ignition source are,
located no less than 18- inches above the floor. Also, the fur-
nace should be protected from physical damage by vehicles.
When a furnace is installed in public garages, airplane han-
gars, or other buildings having hazardous atmospheres, the
unit must be installed in accordance with the recommended
good practice requirements of the National Fire Protection
Association, Inc.
II. AIR FOR COMBUSTION AND VENTILATION
Provisions for adequate combustion and ventilation air
must be provided in accordance with Section 5.3, Air for
Combustion and Ventilation, of the National Fuel Gas Code,
ANSI Z223.1-1988, or applicable provisions of the local
building codes.
Canadian installations must be installed in accordance with
CAN /CGA.B149 Installation Code, and all authorities hav-
ing jurisdiction.
®
CAUTION: Mr for Combustion must not be cony
Laminated by halogen compounds, which include fluoo-
ride, chloride, bromide and iodide, .
These elements are found in Aerosol sprays, detergents,
bleaches, cleaning solvents, salts, air freshener#, and
other household products
All fuel burning equipment must be supplied with air for
combustion of the fuel. Sufficient air MUST be provided to
insure there will not be a negative pressure in the equipment
room or space. In addition, a positive seal MUST be made
between the furnace cabinet and the return -air duct to avoid
pulling air from the burner area and draft safeguard
opening.
The requirements for combustion and ventilation air depend
upon whether the furnace is located in a confined or uncon-

A. Unconfined Space
An unconfined space must have at least 50 cubic feet for
each 1000 Btuh of input for all the appliances (i.e. furnaces,
clothes dryer, water heaters, etc.) in the space.
For Example:
If the unconfined space is of unusually tight construction,
air for combustion and ventilation MUST come from either
the outdoors or spaces freely communicating with the out-
doors. Combustion and ventilation openings must be sized
the same as for a confined space. A minimum opening hav-
ing a total of not less than 1 square inch per 5000 Btuh of
total input rating for all equipment must be provided.
Return air must not be taken from the room, unless an equal
or greater amount of air is supplied to the room.
B. Confined Space
A confined space MUST have two permanent openings, one
within 12- inches of the ceiling, and the other within 12-
inches of the floor. See Figure 2.
NOTE: In determining the free area of an opening, the
blocking effect of the louvers, grilles and screens must be
considered. If the free area of a louver or grille design is
unknown, it may be assumed that wood louvers have a 20
percent free area and metal louvers or grilles have a 60 per-
cent free area. Screens, when used, must not be smaller than
1/4 -inch mesh. Louvers and grilles must be constructed so
they cannot be closed.

The size of the openings depend upon whether the air comes
from inside or outside of the structure.
1. All air from inside the structure:
Each opening MUST have at least 1 square inch of free
area per 1000 Btuh of the total input for all equipment
within the confined space, but not less than 100 square
inches per opening. See Figure 2.
For Example:
If the building is of unusually tight construction, a perma-
nent opening directly communicating with the outdoors
shall be provided. This opening shall have a minimum free
area of 1 square inch per 5000 Btuh of total input rating for
all equipment in the enclosure.
If the furnace is installed on a raised platform to provide a
return air plenum, and return air is taken directly from the
hallway or space adjacent to the furnace, all air for combus-
tion must come from outdoors. See Figure 3.
2. All air from outdoors:
a. If combustion air is taken from outdoors through
vertical ducts, the openings and ducts MUST have
at least one square inch of free area per 4000 Btuh
of the total input for all equipment within the con-
fined space.
For Example:
b. If combustion air is taken from the outdoors
through horizontal ducts, the openings and ducts
MUST have at least one square inch of free area per
2000 Btuh of the total input for all equipment
within the confined space.

A. Construct a Working Platform
1. Construct working platform on location where all
required furnace clearances are obtainable. See Table I
and Figure 7.
B. Install Furnace
1. Position furnace in desired location.
2. Connect gas supply pipe, see Figure 7 for typical piping
entry.
3. Connect supply - and return-air ducts.
a. Install field- supplied filter retainers as indicated in
Figure 8 and Table IV before connecting return-air
duct to furnace.
4. Install 24- x 24 -inch sheet metal shield on platform in
front of louvered control panel, as shown in Figure 7.
V. HORIZONTAL CRAWL SPACE INSTALLATION
The furnace can be installed horizontally with either the LIi
or RH side up. In a crawl space, the furnace can either be
hung from the floor joist or installed on suitable blocks or
pad. The furnace can be suspended from each corner by
hanger bolts (four each 3/8 -inch all- thread rod) cut to desired
length, 1 x 3/8 flat washer, 3/8 lockwasher, and 3/8 nut.
Dimples are provided for hole locations. See Figure 1.
The horizontal crawl space installation is very similar to the
attic; therefore, refer to Section IV, Subsection B, Steps 1,
2, and 3. The installation of a sheet metal shield in front of
the louvered control panel is covered in Step 4. For a crawl
space installation, this same sheet metal shield must be
installed above the louvered control panel. Extend the sheet
metal shield over the furnace top far enough to cover the
gas pipe entry hole.
VI. FILTER ARRANGEMENT
The two factory- supplied filters are shipped in the blower
compartment. After the return-air duct has been connected
to the furnace, install the filters in a V- formation inside the
return -air plenum. See Figure 8 and Table IV for horizontal
applications. Horizontal filter retainers must be field sup-
plied. See Figure 9 for downflow applications.

VII. GAS PIPING
Gas piping must be installed in accordance with national
and local codes. Refer to the current edition of the National
Fuel Gas Code.
Canada installations must be installed in accordance with
CAN /CGA.B149 Installation Code, and all authorities hav-
ing jurisdiction.
The gas supply line should be a separate line directly from
the meter to the furnace, if possible. Refer to Table V for
recommended gas pipe sizing. Risers should be used to con-
nect to the furnace and to the meter.
Piping should be pressure - tested in accordance with local
and national plumbing and gas codes before the furnace has
been attached. If the pressure exceeds 0.5 psig (14 -inch wc),
the gas supply pipe must be disconnected from the furnace
and capped before the pressure test. If the test pressure is
equal to or less than 0.5 psig (14 -inch wc), close the manual
shut -off valve located on the gas valve before the test. It is
recommended that the ground joint union be loosened
before pressure testing.
After all connections have been made, purge the lines and
check for gas leakage.
Install a sediment trap in the riser leading to the furnace.
Connect a capped nipple into the lower end of the tee. The
capped nipple should extend below the level of the gas con-
trols. See Figure 10.
Joint compounds (pipe dope) should be applied sparingly

IX. VENTING
These instructions are to be used only for 376C Furnace
vent systems. These furnaces are equipped with induced -
combustion blowers, and are classified as Category I type
furnaces in accordance with ANSI /A.G.A. Z21.47 central
furnace standards. Category I furnaces use nonpositive,
noncondensing vent systems, and may be connected to lined
masonry chimneys sized and installed per the National Fuel
Gas Code.
However, the venting of this furnace into a lined masonry
chimney could result in the formation of flue gas condensate
due to cold surfaces and oversizing. If condensate is present
in the masonry chimney, a drain must be provided to pre-
vent condensate flow into the vent connector and furnace.
Refer to the National Fuel Gas Code, Section 7.9 for addi-
tional information on condensate drains. Field experience on
induced - combustion furnaces has shown that venting
through a properly sized Type B -1 vent significantly
reduces the occurrence of vent condensation. Any conden-
sate formed is acidic and could cause corrosion of the vent
materials. Therefore, manufacturer suggests (but does not
require) that these furnaces be connected to vent systems
constructed of Type B -1 vent material.
A. General Instructions
1. This furnace must be installed in accordance with these
instructions, the National Fuel Gas Code NFPA No.
54- 1988 /ANSI Z223.1 -1988, Canadian CAN /CGA.B149
requirements, all applicable local codes, and all authori-
ties having jurisdiction.
2. This furnace must not be connected to a chimney flue
servicing a separate appliance designed to burn solid
fuel.
3. Never connect this furnace to a chimney serving a fire-
place, unless the fireplace opening is permanently
sealed off.
4. The recommended vent system for this furnace is con-
structed of Type B -1 double -wall vent pipe (UL or ULC
listed). A minimum 1 -inch clearance is required
between the Type B -1 vent pipe and combustible
material.
—8—
5. It may be necessary to add insulation to the Type B -1
double -wall vent and to single -wall vent connector, if
allowed by local codes, in some applications.
When insulation is required, it must be at least 1 -inch
thick fiberglass with a foil backing. Using permanent
foil tape, attach insulation to vent pipe. (Both the foil
tape and fiberglass insulation must be suitable for tem-
peratures up to 350 degrees F).
6. Insulation must be added to any vent connector which
will be exposed to ambient temperatures of 30 degrees
fahrenheit or less, especially any application using
single -wall vent pipe as a connector.
Add insulation to Type B -1 vent in applications as indi-
cated in venting tables with an asterisk(*).
Do not insulate vent pipe exposed to outdoor weather
conditions (i.e. above roof lines).
7. Do not use a vent size smaller or larger than the size
shown in Tables VII thru XIV.
8. If this furnace is connected to a lined, masonry chim-
ney, the chimney must be sized and installed according
to the provisions of the National Fuel Gas Code, or
Canadian CAN /CGA.B149 requirements. Vent connec-
tors from the furnace to the chimney should be made
with insulated single -wall vent pipe or Type B -1 vent
pipe. Insulate per Section A.5 when required.
9. Installation of the vent pipe should be as direct as pos-
sible, with a minimum number of turns or elbows.
10. Maintain a minimum of 1/4 -inch upward slope per lin-
ear foot on all horizontal vent pipe runs.
11. Rigidly support the vent pipe every 5 feet or less with
hangers or straps to ensure that there will be no move-
ment after installation.
12. No portion of the vent system shall extend into, or pass
through, any circulation air duct or plenum.
13. The Type B -1 vent system shall terminate above the
roof surface per the National Fuel Gas Code or CAN/
CGA.B149 requirements, and shall include a UL or
ULC listed vent cap or roof assembly, unless prohib-
ited by local codes.
14. This furnace may be common vented with another fur-
nace or other listed gas -fired appliances. Total input
rates of all appliances will determine the vent size. See
Sections C and D for additional information.
15. If a common vent system becomes blocked, the furnace
will be shut off by the draft safeguard switch located
on the inducer assembly.
16.
17.
All vent pipe passing through floors, ceilings, and walls
must be installed with the proper clearances from com-
bustible material, and be fire- stopped according to the
National Fuel Gas Code requirements and Canadian
standards CAN /CGA.B149.
In replacement installation, where an existing vent sys-
tem may be used, the vent system must be inspected
for condition, size, type of vent material, and height to
meet these instructions. If the existing vent system is
larger than shown in Tables VII thru XIV, the vent
system will be oversized, and condensation could occur

causing corrosion of the vent system. Installation of a
replacement vent system may be required.
18. When removing an existing furnace from a common
vent system, the vent system is likely to be oversized
for the remaining appliances. Refer to Section E for
additional information.
19. Vent connectors or vents servicing Category 1 appli-
ances shall not be connected into any portion of
mechanical draft systems operating under positive
pressure.
20. For installation of vent systems not covered in Section
IX. B, C, or D (or for vent system lengths /heights
beyond those shown) refer to the National Fuel Gas
Code for information. Following the National Fuel Gas
Code requirements will provide for an acceptable vent
system and proper operation of the furnace.
B. Venting Tables For Dedicated Vent System (one 376C
Furnace)
The following tables are used to size a vent system for one
376C Furnace when using a dedicated vent system. The
tables indicate the maximum horizontal length of vent pipe
allowed for a vent system of a set height and number of
elbows. Some tables also include information for vent
lengths allowed when insulation is added to the vent connec-
tor or vent. See Tables VII thru XI and Figure 14,
1. If single -wall vent pipe is used for vent connector, it
must be insulated as indicated in venting table data
marked with an asterisk (9. Insulation must be added
as specified in Section A.5 and A.6. Insulation should
be added to any single -wall vent pipe used as a vent
connector, especially those applications with long (over
5 feet) vent connector runs.
2. Each table is for a specific size of furnace, depending
upon the rated furnace input.
3. For all applications, the horizontal length of vent and
vent connector must not exceed the vertical height of
the vent system.
4. The addition of insulation to the vent and vent connec-
tor allows for the use of longer horizontal runs in cer-
tain applications marked with an asterisk (9 in the
vent tables.
5. When Type B -1 vent pipe is used for the vent connec-
tor, it must be insulated as indicated with an asterisk
(9 in the vent tables.

gle vent system. Do not connect more than four 376C Fur-
naces into a common vent system. Table XII provides data
for vent systems where all furnaces are of the same size.
For common vent applications using various sizes of 376C
Furnaces, contact your Dealer /Distributor for more
information.
To determine the proper common vent size, total the heat
input of all the appliances to be connected to the vent sys-
tem. Next, select the smallest vent size which will meet that
rated input. NOTE: A listed single -wall to Type B - vent
adaptor is required if single -wall vent pipe is used for the
vent connector.
1. Vent connectors should be as short and direct as possi-
ble, and should be made of Type B -1 double -wall vent
pipe or insulated single -wall vent pipe.
2. Vent connectors shall be sized using dedicated venting
tables shown in Section B. The length of horizontal run
used in the vent connector and vent must never exceed
the height of the common vent.
3. Vent connectors should be spaced at least 1 foot apart
when entering the common vent system.
4. Insulated vent connectors may be required for certain
applications. See Sections A.5. and A.6. for additional
information.
5. For multi -story installation, refer to Appendix G of
National Fuel Gas Code or Canadian standards CAN/
CGA.B149 for additional information in sizing the com-
mon vent. Individual vent connectors should be sized
per the dedicated appliance tables shown in Section B.

D. Venting Tables For Common Vents (one 376C Furnace
and gas hot water heater)
The information in this section refers to the installation of a
common vent serving a 376C Furnace and a gas hot water
heater. Tables XIII and XIV use typical water heater input
rates of 40,000 or 50,000 Btuh. Refer to the water heater
rating plate for input ratings of the installed equipment.
1. Size the common vent and vent connector lengths
using Tables XIII and XIV.
2. The vent connectors should be as short and direct as
possible.
3. Size gas water heater vent connector per National Fuel
Gas Code. The 376C Furnace vent connector should be
sized using tables in Section 13 to determine allowable
lengths, number of elbows, and insulation require-
ments. The allowable vent connector length for the fur-
nace cannot exceed 15 feet for any common vent instal-
lation or application, as shown in Tables XIII and
XIV.
4. Insulated vents and vent connectors may be required
for certain applications. See Table XIV. When insula-
tion is required, it must be installed as indicated in Sec-
tions A.6. and A.6.
5. If the vent connector is exposed to ambient tempera-
tures of 30 degrees fahrenheit or less, it must be insu-
lated as indicated in Section A.5 and A.6.
6. The vent connectors must be spaced within 3 feet of

8. For multi -story installation, refer to Appendix G of
National Fuel Gas Code or Canadian standards CAN/
CGA.B149 for additional information to size the com-
mon vent. Individual vent connector for the furnace
should be sized per single appliance tables found in Sec-
tion B. The water heater vent connector must be sized
per the National Fuel Gas Code.
E. Removal of Existing Furnaces From Common Vent
Systems
1. These steps shall be followed with each appliance
remaining connected to the common vent system
placed in operation, while the other appliances remain-
ing connected to the common vent system are not in
operation.
2. Seal any unused openings in the common vent system.
3. Visually inspect the vent system for proper size and
horizontal pitch, and determine there is no blockage or
restriction, leakage, corrosion, and other deficiencies
which could cause an unsafe condition.
4. Insofar as practical, close all building doors and win-
dows and all doors between the space in which the
appliances remaining connected to the common vent
system are located and other spaces of the building.
Turn on clothes dryers and any appliance not con-
nected to the common vent system. Turn on any
exhaust fans, such as range hoods and bathroom
exhausts, so they operate at maximum speed. Do
not operate a summer exhaust fan. Close fireplace
dampers.
5. Follow the lighting instructions and place the appli-
ance in operation. Adjust the thermostat so appliance
will operate continuously.
6. Test for flue gas spillage at the drafthood relief open-
ing (or draft safeguard tube opening) after 5 minutes of
main burner operation. Use the flame of a match or
candle, or smoke from a cigarette, etc.
7. After it has been determined that each appliance
remaining connected to the common vent system
properly vents when tested as above, return doors, win-
dows, exhaust fans, fireplace dampers, any other gas -
burning appliances to their previous condition of use.
8. If improper venting is observed during any of the
above tests, the common vent system must be cor-
rected. The vent system or vent connectors may need
to be resized. Resize any 376C Furnace vent system
according to these instructions. For any other appli-
ances when resizing vent systems or vent connectors,
the system or connector must be sized to approach the
minimum size as determined using the appropriate
table found in Appendix G of the National Fuel Gas
Code, or Section 5 of CAN /CGA.B149 for Canadian
standards.
X. STARTUP, ADJUSTMENT, AND SAFETY CHECK
A. General
The furnace must have a 115 -volt power supply properly
connected and grounded. Proper polarity must be main-
tained for proper operation. Thermostat wire connections at
R,W,C, and Y must be made at the 24 -volt terminal block on
the control board. The gas service pressure must not exceed
0.6 psig (14 inch wc), but must be no less than 0.16 psig (4.5
inch wc).
Before operating the furnace, check each manual reset
switch for continuity. If necessary, press the button to reset
the switch.
The blower compartment door must be in place to complete
the 116 -VAC circuit to the furnace.

B. Sequence of Operation
Using the schematic diagram, Figure 13, follow the
sequence of operation through the different modes. This fur-
nace has a new and unique control system, therefore, read
and follow the wiring diagram very carefully.
1. Heating mode
The wall thermostat "calls for heat," closing the R and
W circuit. The furnace control performs a selfcheck,
verifies the pressure switch contacts are open, and
starts the inducer motor.
a. Prepurge period —As the inducer motor comes up to
speed, the pressure switch contacts close to begin a
15 second prepurge period.
b. Ignitor warm up —At the end of the prepurge
period, the ignitor is energized for a 17 second igni-
tor warm -up period. If ignition is not established
during the first cycle, the next warm -up period is
increased to 45 seconds. All subsequent ignition
cycles will be 46 seconds, or until the 116 -VAC
power supply is interrupted. By interrupting the
115 -VAC power supply, the warm -up period is auto-
matically reset to 17 seconds.
c. Ignition sequence —When the ignitor warm -up
period is completed the gas valve opens, permitting
gas flow to the burners where it is ignited. After 5
seconds, the ignitor is deenergized and a 2 second
flame sensing period begins.
d. Flame sensing —When burner flame is sensed, the
control begins the blower "on" delay period and
continues holding the gas valve open. If burner
flame is not sensed, the control will close the gas
valve and repeat the ignition cycle.
e. Blower on delay -60 seconds after burner flame is
proven, the blower motor is energized on heating
speed. Simultaneously, the humidifier and electronic
air cleaner terminals (HUM -1 and C for humidifier,
EAC -1 and EAC -2 for electronic air cleaner) are
energized.
f. Blower off delay —When the thermostat is satisfied,
the circuit between R and W is broken, deenergizing
the gas valve stopping gas flow to the burners. The
blower motor, humidifier, and air cleaner will remain
energized 90, 135, 180, or 226 seconds (depending
on the blower off -time selection). The furnace is
factory -set for a 136 - second blower off delay.
Post purge —The inducer motor will remain ener-
gized 6 seconds after the burners are extinguished.
2. Cooling mode
The thermostat "calls for cooling" closing R -G and R -
circuits. The R -Y circuit starts the outdoor condensing
unit, and the combined R -Y and R -G circuit starts the
furnace blower motor on cooling speed. The electronic
air cleaner EAC terminals are energized with 115 VAC
whenever the blower is operating on cooling speed.
When the thermostat is satisfied, R -G and R -Y circuits
are broken. The furnace blower will continue operating
on cooling speed for an additional 90 seconds.

When the R -G circuit is made, the blower motor will
operate on heating speed. During a call for heat, the
blower will stop allowing the furnace heat exchangers
to heat up more quickly.
The blower will revert to continuous operation after the
heating cycle is completed.
When the thermostat "calls for cooling," the blower
will operate on cooling speed. When the thermostat is
satisfied, the blower will operate an additional 90 sec-
onds before reverting back to continuous operation on
heating speed.
4. Heat pump mode
When installed with a heat pump, the furnace control
automatically changes the timing sequence to avoid
long blower off time during demand defrost cycles.
When the W -Y or W -Y -G thermostat inputs are
received together, the control will change the blower to
heating speed or start the blower if it was off, and
begin a heating cycle. The blower will remain on until
the end of the purge period, then shut off until the end
of the ignition warm up and trial for ignition periods (a
-13-
TABLE XV -MODEL 376C ORIFICE SIZE AND MANIFOLD PRESSURE FOR CORRECT INPUT RATE
(Tabulated data based on altitude up to 2000 feet and 23,000 Btuh per burner.)
total of 24 seconds). The blower will then come back on
at heating speed.
When the W input signal disappears, the control will
begin the normal inducer post -purge period and the
blower will change to cooling speed after a one second
delay. If the W -Y -G signals should disappear together,
the blower will remain on for the selected heating
blower off delay period, and the inducer will go through
its normal post -purge period. If the W -Y inputs should
disappear, leaving the G signal input, the control will
go into continuous blower and the inducer will remain
on for the normal post -purge period.
While in heat pump mode, the control will use only the
17 second ignition warm -up period, and will not use the
45 second period at all. The control will initiate a 90
second blower only on delay before starting another
heat pump cycle, if there is a power interruption. Any
time the control senses false flame, the control will lock
out of the heating mode. This occurs because the con-
trol cannot sense the W input due to the false flame
signal, and as a result sees only the Y input and goes
into cooling mode blower off delay. All other control
functions remain in standard format.
C. Startup Procedures
1. Self test —The furnace features a self -test system to
help diagnose a system problem in the case of a compo-
nent failure. Two test pins (ST -1 and ST -2) are located
in the upper right -hand corner of the control board as
shown in Figure 10. To initiate the self -test procedure,
momentarily short across the two pins.
NOTE: The self -test feature will not operate if the con-
trol board is receiving any thermostat signals.
The self -test sequence is as follows:
a. The furnace control will check itself and then oper-
ate the inducer motor for 10 seconds, then off.
b. The hot surface ignitor is then energized for 15 sec-
onds, then off.
c. The humidifier relay is then energized for 10 sec-
onds, then off.
d. The blower motor will operate on cooling speed for
10 seconds, then off.
e. The blower motor will operate on heating speed for
10 seconds, then off.
2. Purge gas lines —After all connections have been made,
purge the lines and check for leaks.

3. To operate furnace, follow procedures on operating
instruction label attached to furnace.
4. With furnace operating, set thermostat below room
temperature and observe that furnace goes off. Set
thermostat above room temperature and observe that
furnace restarts.
D. Adjustments
1. Set gas input rate.
There are two methods of adjusting the gas input rate.
The preferred method is by using Table XV and Step a.
The second method is by clocking the gas meter and
Step b.
The gas valve regulator has been nominally -set at 3.5
inches wc for natural gas. When adjusting input rate,
do not set manifold pressure above 3.8 or below 3.2
inches wc.
a. Check gas input rate using Table XV.
(1.) Obtain average yearly heat value for local gas
supply.
(2.) Obtain average yearly specific gravity for local
gas supply.
(3.) Verify furnace model. Table XV can only be
used for Model 376C Furnaces.
(4.) Check and verify orifice size in furnace.
NEVER ASSUME THE ORIFICE SIZE,
ALWAYS CHECK AND VERIFY.

(6.) Follow heat value and specific gravity lines to
point of intersection. Find orifice size and mani-
fold pressure settings for proper operation at
given natural gas conditions.
EXAMPLE:
Heat value 1070 Btu /cu feet
Specific gravity 0.58
Therefore; Orifice No. 44•
Manifold pressure 3.6 inches wc
The furnace is shipped with No. 43 orifices. Therefore, in
this example all main burner orifices must be changed and
L the manifold pressure must be adjusted.
(7.) Proceed to Step c. to adjust manifold pressure.
b. Check gas input rate by clocking gas meter.
(1.) Obtain average yearly heat value for local gas
supply.
(2.) Check and verify orifice size in furnace.
NEVER ASSUME THE ORIFICE SIZE,
ALWAYS CHECK AND VERIFY.
(3.) Turn off all gas appliances and pilots.
(4.) Start furnace and let run for 3 minutes.
(5.) Measure time (in seconds) for gas meter to com-
plete one revolution.
(6.) Refer to Table XVI for cubic feet of gas per
hour.
(7.) Multiply gas rate cu ft /hr x heating value (Btu/
cu ft).
'EXAMPLE:
Btu heating input = Btu /cu ft times cu ft /hr
'Heating value of gas = 1070 Btu /cu ft
Time for one revolution of 2 -cu /ft dial = 72 seconds
'Gas rate = 100 x 1070 = 107,000 Btuh

(8.) Measured gas input should not exceed gas
input on unit rating plate.
(9.) Proceed to Step c. to adjust manifold pressure.
c. Adjust gas input.
(1.) Remove regulator adjustment seal cap. See Fig-
ure 17.

(2.) Turn adjusting screw counterclockwise to
decrease input. Turn screw clockwise to
increase input. DO NOT set manifold pressure
less than 3.2 or more than 3.8 maximum inches
we for natural gas. Make any major adjust-
ments by changing main burner orifices.
(3.) When correct input is obtained, replace regula-
tor seal cap. Main burner flame should be clear
blue, almost transparent. See Figure 18.

e. Canadian installations only.
The Canadian ratings are approved for altitudes up
to 2000 feet for natural and propane gases. High
altitude ratings are from 2000 feet to 4500 feet
above sea level. See Table XVII for nominal burner
orifice size. High altitude input ratings include a
10% derate as required by Canadian Standards.

2. Set temperature rise.
Do not exceed the temperature rise range specified on
the unit rating plate. Determine the air temperature
rise as follows:
a. Place duct thermometers in return and supply ducts
as near furnace as possible. Be sure thermometers
do not "see" heat exchangers so that radiant heat
will not affect thermometer readings. This is partic-
ularly important with straight -run ducts.
b. When thermometer readings stabilize, subtract
return -air temperature from supply -air temperature
to determine temperature rise.
c. Adjust air temperature rise by adjusting blower
speed. Increase blower speed to reduce temperature
rise. Decrease blower speed to increase temperature
rise.

3. Set thermostat heat anticipator
The thermostat heat anticipation must be set to match
the amp draw of the electrical components in the R -W
circuit. Accurate amp draw readings can be obtained at
thermostat subbase terminals R & W. Figure 19 illus-
trates an easy method of obtaining the actual amp
draw. The amp reading should be taken after the
blower motor has started. See the thermostat manufac-
turer's instructions for adjusting the heat anticipator
and for varying the heating cycle length.
NOTE: When using an electronic thermostat, set cycle rate
for three cycles per hour.

E. Check Safety Controls
The flame sensor, gas valve, and pressure switch were all
checked in the Startup Section as part of normal operation.
1. Check Primary limit control.
This control shuts off the combustion control system
and energizes the circulating -air blower motor if the
furnace overheats.
The preferred method of checking the limit control is to
gradually block off the return air after the furnace has
been operating for a period of at least 5 minutes. As
soon as the limit has shutoff the burners the return-air
opening should be unblocked. By using this method to
check the limit control, it can be established that the
limit is functioning properly and will "operate" if there
is a motor failure.
2. Check draft safeguard switch.
The purpose of this control is to permit the safe shut-
down of the furnace during certain blocked vent
conditions.
a. Disconnect power to furnace and remove vent con-
nector from furnace outlet collar. Be sure to allow
time for vent pipe to cool down before removing.
b. Set room thermostat above room temperature and
restore power to furnace.
c. After normal startup, allow furnace to operate for 2
minute, then block (100%) flue outlet. Furnace
should cycle off within 2 minutes.
d. Remove blockage and reconnect vent pipe to fur-
nace outlet collar.
