DIRECT VENTING
The 350MAV Furnaces require a dedicated (one 350MAV furnace
only) direct -vent system. Ina direct -vent system, all It for
umtbustton is taken directly from outside atmosphere, and all flue
products are discharged to outside atmosphere.
1, REMOVAL OF EXISTING FURNACES FROM
COMMON VENT SYSTEMS
if furnace being replaced was connected to a common vent system
with other appliances, the following steps shall be followed with
each appliance connected to the venting system placed in opera
tkm, while any other appliances connected to the venting system
are not In operation:
I. Seal any unused openings in the venting system.
2, Inspect the venting system for proper slzc and horizontal
pitch as required in the National Fuel Oas Code, ANSI
222.3,1 or the CAN /COA B149 installation Codes and these
instructions. Determine that there is no blockage or restric-
tion, leakage, corrosion, and other deficiencies which could
cause an unsafe condition.
3. in so for as Is practical, close all building doors and
windows and all doors between the apace U which the
appliance(s) connected to the venting system are Iocatod
and other spaces of the building. Turn on clothes dryers and
any appliance not connected to the venting system, Turn on
any exhaust fans, such as range hoods and bathroom
exhausts, so they shall operate at maximum speed. Do not
operate a summer exhaust fan. Close fireplace dampers,
4. Follow the lighting instructions, Place the appliance being
inspected In operation, Adjust thermostat so appliance shall
°poste continuously.
5. Teat for draft hood equipped appliance spillage at the draft
hood relief opening after 5 minutes of main burner opera-
tion. Use the flame of a match or candle.
(1. After It has been determined that each appliance connected
to the venting system properly vents when tested as outlined
above, return doors, windows, exhaust fans, fireplace damp -
ors, and any other gas- burning appliance to their previous
conditions of use.
7. If improper venting is observed during any of above tests,
the venting system must be corrected.
Vent system or vent connectors may need to be resized, For any
Hiller appliances when resizing vent systems or vent connectors,
YYytum or connector must be sized to approach minimum size as
determined using appropriate table found in the NFOC or NSC•

11. COMBUSTION-AIR AND VENT PIPING
A. General
t'ranhustion -air and vent pipe fittings must conform to American
Notional Standards Institute (ANSI) standards and American
Society for Testing and Materials (ASTM) standards D1785
—20—
(schedule -40 PVC), ■2665 (PVC -DWV), D2241 (SDR -21 and
SDR -26 PVC), D2661 (ABS -DWV), F628 (schedule -40 ABS), or
F891 (PVC -DWV cellular core). Pipe cement and primer must
conform to ASTM standards D2564 (PVC) or D2235 (ABS), See
Table 5 for maximum pipe lengths and Fig. 31, 32, 33, 34, and 35
for exterior piping arrangements.
In Canada construct all combustion -air and vent pipes for this unit
of CSA or ULC certified schedule -40 PVC, PVC -DWV or
ABS -DWV pipe and pipe cement, SDR pipe is NOT approved in
Canada.
NOTE: Furnace combustion -air and vent pipe connections are
sized for 24n. pipe. Any pipe size change should be made outside
furnace casing in vertical pipe. (See Fig. 27.) This allows proper
drainage of vent condensate.

NOTES:
1. If installing 2 adjacent 350MAV Furnaces, refer to Multivenang and Vent
Terminations section for proper vent configurations.
2. When locating combustion•air and vent terminations, consideration must be
given to prevailing winds, location, and other conditions which may cause
recirculation of the appliance's own flue products or the flue products of
adjacent vents. Recirculation can cause poor combustion, inlet condensate
problems, and accelerated corrosion of heat exchangers.

Pig. 2E—Combustion-Air and Vent Pipe Connections
: When combustion•air pipe is Installed
above a suspended ceiling, pipe must be insulated with
A 3/8-in. thick Armaflex -typo insulauaa. Combustion -air
pipe should also be insulated when it passes through
want, humid space.
CAUTION: When vent pipe is exposed to temperatures
below freezing, such as when it passes through an
unheated space or when a chimney is used u a raceway,
pipe must be insulated u shown in Table 6 with
Armaflex•typo insulation.
CAUTION: Combustion air must not be taken from
inside structure because inside air is frequently contami-
nated by halogens, which include fluorides, chlorides,
bromides, and iodides. These elements are found in
aerosols, detergents, bleaches, cleaning solvents, salts, air
fresheners, adhesives, paint, and other household prod-
ucts. Locate combustion -air inlet as far as possible from
swimming pool and swimming pool pump house.
Excessive exposure to contaminated combustion air will
result in safety and performance related problems.
- --21 --
WARNING: Solvent cements are combustible. Keep
away from heat, sparks, and open flame. Use only in
well- ventilated areas. Avoid breathing in vapor or allow-
ing contact with skin or eyes. Failure to follow this
warning could result in rue, property damage, personal
injury, or death.
a
WARNING: All combustion -air and vent pipes must be
airtight and watertight. Pipes must also terminate exactly
as shown in Fig. 31, 32, 33, 34, or 35. Failure to follow
this warning could result in property damage, personal
injury, or death.
-4 NOTE: The minimum combustion -air and vent pipe length (each)
for these furnaces is 5 ft. Short pipe lengths (5-8 ft) may discharge
water dropkts. These droplets may be undesirable, and a 12 -in.
minimum offset pipe section is recommended, as shown in Fig. 29,
to reduce excessive droplets from exiting vent pipe outlet.
I!. Combustion -Air and Vent Pipe Diameter
-4 Determine combustion -air and vent pipe diameter.
1. Using Table 5, individually determine the combustion -air
and vent pipe diameters. Pick the larger of these 2 pipe
diameters and use this diameter for both combustion -air and
vent pipes.
2. When installing vent systems of short pipe length, use the
smallest allowable pipe diameter. Do not use pipe size
greater than required or incomplete combustion, flame
disturbance, or flame sense lockout may occur,
NOTE: Do not count elbows or pipe sections in terminations or
within (Unlace, See shaded areas in Fig. 31, 32, 33, 34, and 35.

EXAMPLE:
An 03608011x0 fltrnace located in Indianapolis, elevation
650 ft above sea level, could bo Installed in an application
requiring 3 elbows and 32 ft of vent pipe, along with 5
elbow. and 34 ft of combustion•alr pipe. Table 5 Indicates
this applicadon would allow a 2 -in, diameter vent pipe, but
require a 2.1/2 in. diameter combustion air pipe (2 -1n. pipe
is good for 35 ft with 3 elbows, but only 30 ft with 5
elbows). Therefore, 2-1/2 in. diameter pipe must be used
for both vent and combustion•air pipes since larger required
diameter must always be used for both pipes. if same
installation were in Albuquerque, elevation 5250 ft above
sea level, installation would require 2.1/2 in, vent pipe and
combustion -air pipe. At 5001. to 6000.ft elevation, 2 -in,
pipe is only good for 17 ft with 5 elbows, and 2.1/2 in. pipe
Is good for 70 ft with 5 elbows.
C, Combustion -Air and Vent Pipe Attachment
NOTE; All pipe Joints must be watertight except attachment of
combustion -air pipe to inlet housing connection, since it may be
necessary to remove pipe for servicing.
1. Attach combustion -air pipe as follows:
a. Determine location of combustion -air intake pipe con-
nection to combustion -air intake housing as shown in
Fig. 28 for application.
b. Reposition combustion -air intake housing plug fitting in
appropriate unused intake housing connection.
c, Insert perforated disk assembly (factory- supplied in
loose parts bag) in intake housing where combustion -air
intake pipe will be connected.

VENT EXTENSION PIPE
Some furnaces are supplied with a PVC vent extension pipe
(2-in. diameter by 124n. long). This pipe has a built4n
channel to assist vent condensate disposal. When this vent
extension pipe is supplled, it must be used to connect the
field vent pipe to furnace inducer housing on ALL upflow
and downflow applicstlons.
NOTE: See libel on vent extension pipe for proper installation.
This pipe may be shortened if an elbow h used to connect vent

TERMINATION KIT INSTALLATION
NOTE: If these instructions differ from those packaged with
termination kit, follow kit instructions.
Combustion -air and vent pipes must terminate outside structure. A
factory accessory termination kit must be installed in 1 of the
installations shown in Fig. 31, 32, 33, 34, or 35. Four termination
kits are available.
1. The 2 -in, termination bracket kit is for 14n., 1 -1/2 in., and
2 -in. diameter 2 -pipe termination systems.
2. The 3 -in. termination bracket kit is for 2.1/2 in. and 3 -in.
diameter 2 -pipe termination systems.
3. The 2 -in. concentric vent/air termination kit is for 1 -in.,
1.1/2 in., 24n., and 2 -1/2 in. diameter pipe systems when
single penetration of wall or roof is desired.
4. The 3 -in. concentric vent/air termination kit is for 2 -1/2 in.
and 34n. diameter pipe systems when single penetration of
wall or roof is desired.
NOTE: Shaded parts in Fig, 31, 32, 33, 34, and 35 are considered
to be termination. These components should NOT be counted
when determining pipe diameter. Roof termination is preferred
since it k less susceptible to damage, has reduced chances to intake
contaminants, and has less visible vent vapors. (See Fig, 31 or 32.)
Sidewall termination may require sealing or shielding of building
surfaces with a corrosive resistance material due to corrosive
combustion products of vent system,
A. Extended Exposed Sidewall Pipes
Sidewall combustion -air and vent pipe terminations may be
extended beyond area shown in Fig. 34 or 35 In outside ambient by
insulating pipes as indicated In Table 6.
I. Determine combustion -air and vent pipe diameters. as
stated above, using total pipe length and number of elbows,
2. Using winter design temperature (used in load calculations),
find appropriate temperature for your application and fur-
nace model.
3. Determine required insulation thickness for exposed pipe
Lengths,
NOTE: Pipe length (ft) specified for maximum pipe lengths
located in unconditioned spaces cannot exceed total allowable pipe
length as specified In Table 5.

Consideration of the following should be made when
determining an appropriate location for termination kit.
a. Comply with all clearance requirements as stated in
Table 4.
b. Termination kit should be positioned where vent vapors
will not damage plants/shrubs or air conditioning equip-
ment.
c, Termination kit should be positioned so that it will not be
affected by wind eddy (such as inside building corners)
or allow recirculation of flue gases, airborne leaves, or
light snow.
d, Termination kit should be positioned where it will not be
damaged by or subjected to foreign objects, such as
stones, balls, etc,
c. Termination kit should be positioned where vent vapors
are not objectionable,

CONDENSATE DRAIN
1. GENERAL
Condensate trap is shipped installed in the blower shelf and factory
connected for UPFLOW applications. Condensate trap must be
RELOCATED for use in DOWNFLOW and HORIZONTAL
applications.
Condensate trap MUST be used for all applications.
An external trap is not required when connecting the field drain to
this condensate trap.
The field drain connection (condensate trap or drain tubs coupling)
is sized for 1/2 -in. CPVC, 1/2 -in. PVC, or 5 /8 -in. ID tube
connection.
Drain pipe and fittings must conform to ANSI standards and
ASTM D1785 or D2846. CPVC or PVC cement and primer must
conform to ASTM D2564 or F493. In Canada, use CSA or ULC
certified schedule 40 CPVC or PVC drain pipe, fittings, and
cement.
—28—
When a condensate pump is required, select a pump which is
approved for condensing furnace applications. To avoid conden-
sate spillage, select a pump with an overflow switch.
-4 Furnace condensate is mildly acidic, typically in the pH range of
3,2 to 4.5, Due to corrosive nature of this condensate, a condensate
pH neutralizing filter may be desired, Check with local authorities
to determine if a pH neutralizer is required.

proper operation, or control will lock out, Control is
grounded through green wire routed to gas valve and
burner box screw.
Using schematic diagram, follow sequence of operation through
different modes. (See Fig. 24.) This furnace has a new control
system, Read and follow wiring diagram carefully.
NOTE: If 115 -v power supply to furnace or blower access panel
switch is interrupted during a call for heat, blower operates for 90
see when power Is restored before heating cycle is resumed,
1. HEATING MODE
When wall thermostat "calls for heat," R -W circuit closes. Furnace
control performs a self- check, verifies pressure switch contacts are
open, and starts inducer motor.
1. Prepurge period ---M inducer motor comes up to speed,
pressure switch contacts close to begin a 15 -sec prepurge
period.
2. Ignitor warm up—At end of prepurge period, ignitor is
energized for a 17 -sec ignitor warm -up period.
3. Ignition sequence —When ignitor warm -up period is com-
pleted, gas valve opens, permitting gas flow to burners
where it is ignited. After 5 sec, ignitor is de- energized and
a 2 -sec flame - sensing period begins.
HUM terminal on control center Is energized with gas
valve. See Accessories — Humidifier section.
4. Flame sensing --When burner flame is sensed, control
begins blower on delay period and continues holding gas
valve open.
If burner flame Is not sensed, control center de onorgizos
gas valve and ignition sequence is repeated.
NOTE: Ignition sequence repeats 3 additional times before a
lockout occurs. Lockout automatically resets after 3 hr or can be
manually reset by turning off 115v (not at (hemostat) for 3 sec
minimum, then turning It on again.
5, Blower on delay —Sixty sec after burner flame is proven,
blower motor Is energized on heating speed, Sitnutta-
neously, electronic air cleaner terminal EAC -1 is energized.
6. Blower off delay —When thermostat Is satisfied, circuit
between R -W Is opened, de- energizing gas valvo (stopping
gas flow to burners) and humidifier, Blower motor and
electronic air cleaner remains energized 90, 135, 180, or
225 sec (depending on blower off time selection). Furnace
is factory shipped sot for a 135 -sac blower off delay.
7, Post purge— Inducer motor remains energized 15 sec after
burners aro extinguished.
II, COOLING MODE
When thermostat "calls for cooling," R -G and R -'s' circuits close.
R -Y circuit starts outdoor condensing unit, and combined R -Y and
R -G circuit starts furnace blower motor on cooling speed. Elec-
Ironic air cleaner EAC -1 terminal is energized with 115v whenever
blower is operating.
When thermostat is satisfied, R.G and R -Y circuits are opened,
furnace blower continues operating on cooling speed for an
additional 90 sec.
PI. CONTINUOUS BLOWER MODE
When R -G circuit is made, blower motor operates on heating
speed.
NOTE: Electronic air cleaner EAC.1 terminal is energized with
115v whenever blower is operating.
If a "call for heat" (R -W) occurs while thermostat is in continuous
blower mode, blower stops to allow furnace heat exchangers to
heat up more quickly, then restarts at end of blower on delay
period of 60 sec.
Blower reverts to continuous operation after heating cycle is
completed.
If a "call for cooling" (R -Y) occurs while thermostat is in
continuous blower mode, blower changes from continuous blower
speed (heating speed) to cooling speed,
When thermostat cooling call is satisfied, R -Y opens and blower
operates an additional 90 sec at cooling speed before reverting
back to continuous operation (heating speed).
IV. HEAT PUMP MODE
When installed with a heat pump, furnace control automatically
changes blower on delay timing sequence to avoid no blower
operation time during demand defrost cycles, When R -W and R -Y
or R -W, R -Y, and R -O thermostat inputs are received at the same
time at furnace control center, control starts blower in heating
speed. Then a gas heat mode begins. Blower remains operating at
heating speed for 15 sec or until end of prepurge period, then
blower shuts off until end of ignitor warm up and trial for ignition
periods (a total of 24 sec). Blower restarts at heating speed,
When R -W thermostat call disappears, control completes inducer
post -purge period (15 sec) and changes to cooling speed after a
2 -sec delay.
If R -W, R.Y. and R -O thermostat signals should disappear
simultaneously, blower remains on for selected heating blower off
delay period (90, 135, 180, or 225 sec), and the inducer goes
through 15 sec post -purge period. If R -W and RA' thermostat
signals should disappear, leaving R -0 thermostat signal, blower
remains on in heating speed and inducer remains on for 15 sec to
complete post -purge period.
Control initiates a 90 -sec blower only on period before starting
another heat pump cycle if there is a power Interruption, Anytime
control senses false flame, control locks out of heating mode, This
reaction occurs because control Ignores W input duo to false flame
signal and, as a result, sees only Y input and goes Into coaling
mode blower off delay. All other control functions remain in
standard format.
NOTE: BAC -1 terminal is energized whenever blower operates.
HUM terminal is only energized when gas valve is energized,
) V. COMPONENT TUT
A. Component Test Sequence
NOTE: All components a c functionally operated except the gas
valve.

sonal injury, or death.
IV, ADJUSTMENTS
-4 A. Set Gas Input Rate
Furnace gas input rate on rating plate Is for installations at altitudes
up to 2000 ft, Furnace input rate must be within 4:2 percent of input
on furnace rating plate.
1. Determine natural gas orifice size and manifold pressure for
correct input.
a. Obtain average yearly heat value (at installed altitude)
from local as supplier.
b. Obtain average yearly specific gravity from local gas
supplier.
c. Verify furnace model. Table 7 can only be used for
model 350MAV furnaces,
d. Find installation altitude in Tabic,
NOTE: For Canada altitudes of 2000 to 4500 ft, use U.S.A.
altitudes of 2001 to 3000 ft in Table 7.
e. Find closest natural gas heat value and specific gravity
on Table 7.
f. Follow heat value and specific gravity lines to point of
intersection to find orifice size and manifold pressure
settings for proper operation.
EXAMPLE: (0-2000 it altitude)
Heating value = 1050 Btu/cu ft
Specific gravity 0.62
Therefore: Orifice No. 45
Manifold pressure 3.64n. we
* Furnace is shipped with No. 45 orifices. In this example
all main burner orifices are the correct size and do not need
to be changed to obtain the proper input rate.

EXAMPLE: (0-2000 ft altitude)
Btu heating input = Btu/cu ft X cu ft/hr
Heating value of gas it 975 Btu/cu ft
Time for 1 revolution of 2 -cu ft dial = 70 sec
Oas rate = 103 cu ft/hr (from Table 9)
Btu heating input = 103 X 975 = 100,425 Btuh
In this example, the orifice size and manifold pressure
adjustment is within ±2 percent of the furnace input rate.
!!. Set Temperature Ries
A
CAUTION: Temperature the must be within llmits
specified on unit rating plate. Recommended operation is
at midpoint of rise or above, Failure to follow this caution
may result in condensing or overheating the heat ex-
changers.
Determine and adjust air temperature rise as follows:
1. Place thermometers in return and supply ducts as close to
furnace as possible. Be sure thermometers do not see heat
exchanger so that radiant heat does not effect readings. This
practice is particularly important with straight•run ducts.
2. When thermometer readings stabilize, subtract return -air
temperature from supply -air temperattire to determine air
temperature rise.
3. Adjust temperature rise by adjusting blower speed, Increase
blower speed to reduce temperature rise. Decrease blower
speed to increase temperature rise.
WARNING: Disconnect 115 -v electrical power before
m changing speed tap. Failure to follow this warning could
result in personal injury.
4. To change blower motor speed selections for heating mode,
remove blower motor lead from control center HEAT
tannins!. (See Fig. 25.) Select desired blower motor speed
lead from 1 of the other terminals and relocate It to HEAT
terminal, See Table 10 ror lead color identification. Region•
nest original lead on SPARE terminal.
Follow this same procedure for proper selection or COOL
speed selection,

C. Adjust Blower OH Delay (Heat Mode)
If desired, the main blower off time delay period may be
lengthened or shortened when operating in the heating mode to
provide greater comfort, See Table 11 for position of switches and
Fig, 24 or 25 for location of switches on control center.
D. Set Thermostat Heat Anticipator
Thermostat heat anticipator must be set to match amp draw of
components in R -W circuit. Accurate amp draw measurements can
be obtained at thermostat subbase terminals R and W,
Fig. 47 illustrates an easy method of obtaining these measure,
ments. Amp reading should be taken after blower motor has
started. See thermostat manufacturer's instructions for adjusting
heat anticipator and for varying heating cycle length.

CHECK SAFETY CONTROLS
I. CHECK PRIMARY LIMIT CONTROL
This control shuts off combustion control system and energizes
air- circulating blower motor If furnace overheats. Recommended
method of checking this limit control Is to gradually block off
return air alter furnace has been operating for a period of at least
5 minutes, As soon u limit control has shut off burners, return-air
opening should be unblocked to permit normal air circulation. By
using this method to check limit control, It can be established that
limit is iltnctloning properly and operates if there Is a restricted
return-air supply or motor failure. If limit control does not function
during this test, cause must be determined and corrected,
II. CHECK PRESSURE SWITCH
This control proves operation of draft inducer. Check switch
operation as follows:
1. Turn off 115 -v power to furnace.
2. Remove main furnace door and disconnect inducer motor
lead wires from wire harness.
3. Turn on 115-v power to furnace.
4. Set thermostat to "call for heat" and wait I minute, When
pressure switch is functioning properly, hot surface ignitor
should NOT glow, and control center diagnostic light
flashes a 31 fault. If hot surface ignitor glows when inducer
motor Is disconnected, shut furnace down immediately,
Determine reason pressure switch did not function properly
and correct condition,
5. Turn off 115 -v power to furnace.
6. Reconnect inducer motor leads, reinstall main furnace door,
and turn on 115 -v power supply.
CHECKLIST
1; skit away tools and instruments..' in up debris.
2.. Verify manual reset switch has cuudnuity.
3. Verity that blower and control access doors are properly

4. Cycle test furnace with room thermostat.
5. Check t Won of accessories per manufacturer's instruc-
tions. '
6. Review User's Guide with owner,
