ADVANTAGES OF ELECTRIC HEAT
CLEANLINESS: Electric heat is the cleanest of all heating methods, thus reducing the cost of maintenance
and cleaning.
LOW INSTALLATION COST: Electric duct heaters require no furnaces, stacks or flues, thereby keeping
installation costs to a minimum, No floor space is required for a duct heater installation.
LOW OPERATING COST: Modern building design with efficient insulation has made electrical heat one
of the most economical in many parts of the nation. Gradual lower costs of producing electricity has
helped to keep operating costs down.

SPECIAL CONSTRUCTION FEATURES AND APPLICATIONS
SLIP -IN MODEL HEATER
On all standard heaters and custom heaters 36" or less in
length, a 3/16" flange is turned inward to assure proper
rigidity. In order to maintain duct surfaces at a low tempera-
ture, heating elements are positioned so that they will be
one Inch or more from the duct. On slip -in heaters a small
amount of by- passed air flows over the bottom and top of
the heater, and keeps the temperature of the duct above
and below the heater within proper limits, Approximately
two to three feet down stream from the heater, the by-
passed air and heated air are mixed with no apparent strati-
fication.
Heaters which are larger then 38" in length or height are
of heavier construction. A 1" flange is turned outward to
strengthen the heater frame and on heaters in excess of
72 ",•a 2" flange Is turned outward. The height and width of
this type of slip -in heater is undersized by 1/4" to Insure
easy installation.
HEATERS FOR ROUND DUCT INSTALLATIONS
Delta Flo is capable of furnishing duct heaters In two different
styles for mounting to round ducte„ A Slip -In or Saddle type of
round adaptor is available whore the heater le to be mounted
In much the same way as our standard slip -in heater. A Flanged
or Collar type of adaptor is available when you with to plug the
duct assembly directly Into the incoming and outgoing sides of
the heater frame. These types of round adaptors are available
to fit from 6" to 38" round duct diameters,
EXTERNAL MANUAL RESET BUTTON
Where It Is desirable, an external manual reset
button can be provided which allows the manual
limit thermostat to be reset without opening the
heater terminal cover.
SADDLE
TYPE
FLANGE -MOUNT HEATERS
Heaters designed for flanged mounting are built with the
Inside face dimension of the heater frame Identical to the
Inside of the duct for which It Is designed. Heaters for ducts
measuring 72" or less In length or height, are built with a
one inch wide mounting flange. Heaters for ducts measur-
ing in excess of 72" In either direction are built with mount-
ing flanges of two Inches In width.
— 2 _-
HINGED COVER
All Delta Flo heaters, whether standard or custom,
come with a permanently attached hinged cover to
the control housing. A separate lid is provided on
dust -tight heaters.
SPECIAL CONSTRUCTION FEATURES AND APPLICATIONS
RECESSED TERMINAL BOX
(FOR SLIP-IN OR FLANGE MOUNT APPLICATIONS):
Construction of this type of special terminal box
allows the over - temperature devices to be recessed
further into the air stream. The recessed terminal
box should be used where there is an internal or
external insulation liner.
When ordering this type of construction specify the
outside duct dimensions and liner thickness.
DUST -TIGHT CONTROL TERMINAL BOX
Delta Flo can provide a dust -tight control terminal
box on Its duct heaters when deslred. This type of
box assembly Is furnished with a door gasket and
sealed seams. No electrical knockouts are provided
with this type of box.

INSULATED CONTROL TERMINAL BOX
Wherever a heater is to be used In an air conditioning
duct where there is a relatively high humidity an In-
sulated terminal box is recommended. The insulation
, is fastened to the back of the control box, which when
installed Into the duct properly, will virtually eliminate
the possibility of condensation forming.
BOTTOM -MOUNT DUCT HEATERS
Delta Fio'e EMBM model duct heater is available
where an application necessitates the bottom
mounting of a heater. Our model EHBM heater is
fully U.L. listed for use with all available components
and Is listed for "zero- clearance Installation ", Both
single and three -phase heaters are available up to
1000 KW in capacity.
SLIP -IN (Type S)
Delta Flo Duct Heaters are offered in three con-
structions. Slip -in standard, slip -in flanged (over
38" In width or height) and flanged mount models.
Slip -in heaters are standard and due to their ease
of Installation are by far the most widely used.
When built -In controls are specified In a standard
slip -in heater, they are usually mounted In the
right hand overhang ( "K" dimension). If desired
left hand overhang must be specified.

INSTALLATION AND MOUNTING LIMITATIONS
Electric heaters produce 100% of their heating capacity (regardless of air flow) as long as the heating elements are
energized. A certain amount of air velocity is required to be evenly distributed across the duct heater face area to
avoid nuisance tripping of the high temperature thermal cutouts.
Certain mounting limitations are illustrated below to aid in providing the minimum air velocity required.

DUCT TRANSITION INSTALLATION
In some air systems, the duct heater may be larger
than the duct work requiring the duct to be en-
larged using a sheet metal transition. The angle of .
the slope of the transition on both the upstream
and leaving sides of the equipment should not
exceed 30 °.
•fM

WTI
INSTALLATION NEAR TURNS
It Is recommended that duct heaters not be install-
ed within 2 feet of a turn in a duct. If however a
heater Is Installed closer than 2 feet to a turn, turn-
ing vanes must be Installed In the turn to straighten
out the air flow across the heater. If the air flow Is
not uniform over the heating elements, premature
element burnout and /or nuisance tripping may be
experienced.
Do not insulate the sides or front of the terminal
box of a heater.
AUTOMATIC AND MANUAL THERMAL CUTOUTS
A primary automatic high temperature limit thermostat Is standard on all Delta Flo heaters. The automatic limit cutout
Is a bimetal snap acting device which will de- energize the heater at a pre - selected temperature. When the heater cools
the automatic limit will automatically re- energize the heater. The automatic limit control is rated at 25 amperes at 240
volts and 22 amperes at 277 volts. This limit control is U.L. listed for 100,000 cycles and Is designed to break contact at
148'' F.
As secondary overtemperature protection a manual reset limit thermostat is provided. This device is standard on all
Delta Flo heaters The manual reset Is designed to open at a higher temperature than the primary automatic cutout. If
cutout temperature Is reached, the secondary manual reset limit must be manually reset, Until the heater cools down
the manual limit control cannot be reset. The manual reset is used in the power circuit except where fusible links are
' specified. Where fusible links are specified, one manual reset cutout is Installed In the control circuit, Manual reset
limit thermostats are rated up to 48 amperes at 600 volts and are U.L. listed for 8,000 cycles. The temperature break
point of this device Is 187° F.
FUSIBLE LINKS (Heater Limiters)
— OPTIONAL SECONDARY PROTICTION —
Fusible links are set at a higher temperature than the automatic thermal cutout, A sufficient number of fusible links are
located directly in the power circuit to de- energize the heater in cave the automatic limit falls to operate. This device
meets the U.L, and N.E.C. requirements for manually replaceable safety devices. Fusible links are serviceable through
the control box without removal of the heater from the duct.
AIR PRESSURE SWITCH
SAFETY DEVICES
The pressure type air switch is the best and most positive method of protection against loss of air flow. Using an air
pressure switch eliminates the field wiring that a fan relay would require. The air pressure switch has a diaphragm that
senses the pressure difference between the inside and outside of the duct.
Specifications; Voltage — 300va pilot duty at 115 to 277v ac, 10 amp non - inductive to 277 v ac.
Adjustible Range -- Make on pressure rise .05 + .02 to 2.0" w,c.
Operating Temperature Range — -40 to 180 °F.
Maximum Pressure -- 1/2 PSI
—6_
MAGNETIC CONTACTORS
Magnetic contactors come in standard ampere ratings up to 48
Amperes (The maximum allowed by N.E.C. and U.L.). All magnetic
contactors used by Delta Flo meet the U.L. requirement of 100,000
cycles per pole. Control coil voltages are available from 24 to 277
volts, When contactors are furnished installed in a Delta Flo heater
the contactor may be supplied as either de- energizing or discon-
necting type as permitted by local codes. A magnetic contactor
when supplied remote must break all power lines, Heaters with
SCR contactors are furnished with a magnetic contactor as a
Safety Sack -Up.
A. De-energize each circuit separately.
B. Interrupt entire control voltage.
COMPONENTS
PILOT LIGHTS AND TOGGLE SWITCHES
Pilot lights are available for 24, 120, 208, 240 or 277 volt operation
and can be installed in the control circuit of a heater to indicate the
following conditions;
A, Heater is energized (one per heater).
S. Circuit is energized (one per circuit).
C. Safety Limit Is open (one per heater).
D. Air Switch Is open (one per heater.)
Toggle switches can be supplied wired into the control circuit and
be installed to do the following:
Important note: Toggle switches will not disconnect power con-
nections and are supplied where disconnecting type contactors
are used.
—7_
MERCURY CONTACTORS
Where minimum noise Is desired, or long life under frequent cycling,
mercury contactors are recommended. Mercury contactors have
no mechanaial moving parte and when installed properly will last
almost indefinitely. Mercury contactors are position sensitive and
must be Installed as labeled on the heater or In remote control panel
housing, Please specify type of duct installation (horizontal or
vertical) and air flow direction when ordering with mercury con-
tactors. Control coil voltages are available from 24 to 277 volts.
Mercury contactors, when not installed per Delta Flo instructions,
are void of warranty.
PRESSURE /ELECTRIC SWITCHES
CIRCUIT BREAKERS
COMPONENTS
Where a pneumatic control system is being used to control electric
duct heaters. P E switches can be furnished built -in or remote as
desired. One P E switch is required for each heater circuit. In-
creases or decreases In control air will energize or de- energize the
heater circuits as required. P E switches supplied by Delta FIo are
adjustable from 2 to 30 PSIG with a fixed differential or 2 PSIG and
a maximum voltage of 25 amps at 277 volts, P E switches are not
factory set and require field adjustments to specific Job require-
ments.
Circuit breakers may be used in place of fusing for overcurrent
protection. Circuit breakers automatically trip off in an overcurrent
condition and are resettabte. Circuit breakers do not interlock with
the door when used to replace circuit fuses, A circuit breaker can
be used to disconnect the entire heater load when that Toad does
not exceed 48 amperes. For heater loads over 48 amperes a circuit
breaker for each circuit must be provided. We recommend circuit
breakers be used when replacing fuses, not as a disconnecting
means, as there is no interlock with the door assembly,
—8—
SAFETY DISCONNECT SWITCHES
Delta Flo electric duct heaters can be furnished with a
safety disconnect switch which will be Interlocked so
that when the terminal box door le opened the power
voltage is automatically broken, All disconnect
switches supplied by Delta Flo are capable of being
locked in the open position.
N.E.C. 424.19 Disconnecting Means: "Means shall be
provided to disconnect all fixed electric space heating
equipment from all ungrounded conductors."
N.E.C. 424-65 Location of Disconnecting Means:
"Duct heater controller equipment shall be accessible
with the disconnecting means Installed at or within
sight of the controller.'
Important note: The use of a fused disconnect switch
does not eliminate the requirement concerning sub -
circuit overcurrent protection (see fusing).
DOOR SAFETY MICRO SWITCH
SUPPLY VOLTAGE TERMINAL BLOCK
COMPONENTS
A control circuit disconnect switch can be provided which will
automatically de- energize the control circuit of a heater when-
ever the heater control box door is opened, This switch is single -
pole double -throw and has a rating of 15 amperes up to 480volts
non - inductive, This switch Is used in the control circuit where
the voltage will not exceed 277 volts. Disconnectinj type con-
tactors must be used when a door safety micro switch is ordered.
This switch does not meet the U.L. or N.E.C. requirement as a
disconnecting means.
A main power supply terminal block can be furnished on all
heaters and are rated up to 800 volts. Where required by U.L. or
N.E.C. these terminal blocks are supplied at no- charge. Control
circuit terminal blocks are standard on all Delta Flo heaters.
Underwriters' Laboratories, Inc. require that on heaters over 48
amperes total load, the heater manufacturer shall provide over -
current protection sub - divided so that each circuit shall not
exceed 48 amperes. Fuses can be furnished built -into the heater
terminal housing or In a remote control panel.
N,E.C, 424-22 Overcurrent Protection: "(b) Resistance Elements.
Electric space heating equipment employing resistance -typo
hosting elements rated more than 48 amperes shall have the
heating elements subdivided, Each subdivided load shall not
exceed 48 amperes and shall be protected at not more than 80
amperes. (o) Overcurrent Protection Devices. The overcurrent
protective devices specified In (b) shall be (1) factory installed
within or on the heater enclosure or provided as a separate
assembly by the heater manufacturer; (2) accessible; and (3)
suitable for branch- oirouit protection. Where cartridge fuses
are used to provide this overcurrent protection, a single dis-
connecting means shall be permitted to be used for several
subdivided loads."

COMPONENTS
Solid state (SCR) electric heater controllers can be provided
built -In or in a remote control panel. SCR's are capable of full
proportional control from 0 to 100% of the heater output. Zero
crossover voltage eliminates R.F.I. (Radio Frequency Inter-
ference). Due to the solid state construction of these controllers
a virtually unlimited working life of these devices is possible,
Delta Flo can provide a Loyola Industries type of controller or a
Hoffman Controls Corporation model as desired.
The Loyola I3PAC series of controllers is designed for a specific
maximum KVA output at a specific input voltage. A special set of
terminals Is provided which can be used to shut off the device
from a remote interlock or limit control.
The Hoffman 701 series controller is a master /slave assembly
which Is capable of continuous modulation In direct proportion
to temperature error. When used with the Hoffman model ther-
mostat a "standby" switch is furnished which will prevent the
heater from operating when no heat is desired.

MAINTENANCE INSTRUCTIONS
Delta Flo Duct Heaters require very little maintenance and when installed according to our instructions,
they will provide many years of trouble free operation.
The installation instructions, provided herewith, should be followed to secure proper operation of the
heater and to assure acceptance by building and safety inspectors.
The minimum air velocity required is shown on the installation instructions. This is the minimum amount
of air required when the heater is used in conjunction with a heat pump or other device where the entering air
is between 95 and 100 degrees F. Where the air tempertiture is 80 degrees F. or less, the heater will operate
satisfactorily with 25 percent less velocity than shown. In order to insure long element life It is necessary to
provide the proper amount of air across the heater.
Where the heater Is found to be cycling out on either the automatic limit thermostat or the manual re -set
limit thermostat or where the fusible link, or links break, it is usually due to one of the following reasons:
(1) insufficient velocity of air across the heater.
(2) improper distribution of air across the heater,
Periodic Inspections should be made of the air filters to ascertain that sufficient air is always available.
Contactors are checked before the heater leaves the factory to assure that they pull In properly and that
there is no chattering, it chattering develops in the field, It is usually due to insufficient voltage from the
control transformer to the holding coil and /or due to dirt or dust between the contacts of the contactor, Either
or both of these conditions should be corrected at the earliest possible time,
If problems arise other than what Is covered above, please feel free to contact the factory,

It is not our desire to charge more for a custom heater than
for a standard heater of the same wattage where the physical
dimensions are the same or smaller. Where a standard heater
can be shortened to meet an application, we will make this
alteration without any additional cost. As an example: We
will furnish a 10 K.W. single -phase heater for a 28 x8 duct for
the same price as a DH- 100124 heater which Is designed
for a duct with dimensions of 30 x 8.

CURRENTS FOR RESISTANCE HEATING LOADS
SINGLE•PHASE AMPERES THREE -PHASE AMPERES
Voltage, power, resistance or current, are the basis of
electricity. Any one of these can be found if any two
are known.
A watt Is a measure of electric power and thus Is the
output of heat In a resistance heater.
CALCULATING KW AMPS AND RESISTANCE
OHM'S LAW
- 32 -
Voltage and current produce a watt,
Example: (W) watts ■ (V) volts times (I) amperes. W I Vi.
Therefore, 208 volts and 18 amperes produce 3120
watts.
