Fasten individual lengths of vent together with at least three
corrosion resistant sheet metal screws.
Keep single wall vent pipe at least 6" from combustible
materials. For double wall vent pipe, follow the vent pipe
manufacturer’s clearances to combustibles. The minimum
distance from combustible materials is based on the
combustible material surface not exceeding 160°F.
Clearance from the vent pipe (or the top of the unit) may be
required to be greater than 6" if heat damage other than fire
could result (such as material distortion or discoloration).
Avoid venting through unheated space when possible.
When venting does pass through an unheated space or
if the unit is installed in an environment that promotes
condensation, insulate runs greater than 5' to minimize
condensation. Inspect for leakage prior to insulating and
use insulation that is noncombustible with a rating of not

be noncombustible.
A11. All seams and joints of the single wall pipe must be sealed
with metallic tape or silastic suitable for temperatures up to
400°F. Wrap the tape two full turns around the vent pipe.
One continuous section of double wall vent pipe may be
used within the vent system. Refer to instruction A12 in
“Section A – General Instructions – All Units” for attaching
double wall pipe to single wall pipe.
A12. The following are General Instructions for Double Wall
(Type B) Terminal Pipe Installation:
How to attach a single wall vent terminal to
double wall (Type B) vent pipe:
1. Look for the “flow” arrow on the vent pipe.
2. Slide the vent terminal inside the exhaust end of the
double wall vent pipe.
3. Drill (3) holes through the pipe and the vent terminal.
Using 3/4" long sheet metal screws, attach the cap to
the pipe. Do not over tighten.
A14. Do NOT vent this appliance into a masonry chimney.
A15. Do NOT use dampers or other devices in the vent or
combustion air pipes.
A16. The venting system must be exclusive to a single
appliance and no other appliance is allowed to be vented
into it.
A17. Precautions must be taken to prevent degradation of
building materials by flue products.
A18. Single wall vent pipe must not pass through any
unoccupied attic, inside wall, concealed space, or floor.
A19. Uninsulated single wall vent pipe must not be used
outdoors for venting appliances in regions where the 99%
winter design temperature is below 32°F.
A20. The vent terminal must be a Gary Steel 1092, Tjernlund
VH1, Starkap, Selkirk, or Constant Air -Flo 2433 style
terminal.
A21. If left hand (facing front of heater with air blowing in face)
power exhauster discharge is desired, the power
exhauster may be rotated 180°. To do this, remove the
screws in the vent collar, rotate the power exhauster, then
replace the screws.
A22. In addition to following these General Instructions, specific
instructions for Vertical Category I or Horizontal Category
III vent systems must also be followed. The following
outlines the differences:
Table 7.2 - ANSI Unit Heater Venting Requirements
How to connect a single wall vent system to a
double wall (Type B) vent pipe:
1. Slide the single wall pipe inside the inner wall of the
double wall pipe.
2. Drill (3) holes through both walls of the single and
double wall vent pipes. Using 3/4" sheet metal screws,
attach the two pieces of pipe. Do not over tighten.
3. The gap between the single and double wall pipe must
be sealed but it is not necessary to fill the full volume
of the annular area. To seal, run a large bead of 400°F
silastic around the gap.
A13. Vent termination clearances must be maintained:

ELECTRICAL CONNECTIONS
DUCT INSTALLATION
WARNING
IMPORTANT
Do not attempt to attach ductwork of any kind to propeller
models.
1. Disconnect power supply before making wiring connections
to prevent electrical shock and equipment damage.
2. All appliances must be wired strictly in accordance with
wiring diagram furnished with the appliance. Any wiring
different from the wiring diagram could result in a hazard to
persons and property.
3. Any original factory wiring that requires replacement must
be replaced with wiring material having a temperature rating
of at least 105°C.
4. Ensure that the supply voltage to the appliance, as indicated
on the serial plate, is not 5% greater than rated voltage.
CAUTION
Ensure that the supply voltage to the appliance, as indicated
on the serial plate, is not 5% less than the rated voltage.
1. Installation of wiring must conform with local building
codes, or in the absence of local codes, with the National
Electric Code ANSI/NFPA 70 - Latest Edition. Unit must be
electrically grounded in conformance to this code. In
Canada, wiring must comply with CSA C22.1, Part 1,
Electrical Code.
2. Two copies of the unit wiring diagram are provided with
each unit. One is located in the electrical junction box and
the other is suppled in the literature packet. Refer to this
diagram for all wiring connections.
3. Make sure all multi-voltage components (motors,
transformers, etc.) are wired in accordance with the power
supply voltage.
4. The power supply to the unit must be protected with a
fused or circuit breaker switch.
5. The power supply must be within 10 percent of the voltage
rating and each phase must be balanced within 2 percent
of each other. If not, advise the utility company.
6. External electrical service connections that must be
installed include:
a. Supply power connection (120, 208, 240, 480, or 600 volts).
b. Thermostats, summer/winter switches, or other accessory
control devices that may be supplied (24 volts).
NOTE: Certain units will require the use of a field step-down
transformer. Refer to the serial plate to determine the unit
supply voltage required. Additional information may be found in
Tables 16.2 and 16.3 and in the step down transformer
installation instructions.
7. Refer to Figure 15.1 for the electrical junction box locations.
8. All supply power electrical connections are made in the
electrical junction box of the unit. The low voltage (thermostat
and accessory control devices) can be wired to the terminals
on the electrical junction box. Refer to the wiring diagram for
the terminal location of all low voltage wiring.
When installing the heater, always follow good duct design
practices for even distribution of the air across the heat
exchanger. Recommended layouts are shown in Figure 11.1.
When installing blower units with ductwork the following must
be done.
1. Provide uniform air distribution over the heat exchanger.
Use turning vanes where required. See Figure 11.1.
2. Provide removable access panels in the ductwork on the
downstream side of the unit heater. These openings should
be large enough to view smoke or reflect light inside the
casing to indicate leaks in the heat exchanger and to check
for hot spots on exchanger due to poor air distribution or
lack of sufficient air.
3. If ductwork is connected to the rear of the unit use Modine
blower enclosure kit or if using field designed enclosure
maintain dimensions of blower enclosure as shown on
page 22.

Additional Requirements for Blower Model BDP
Determining Blower Speed
The drive assembly and motor on all blower units are factory
assembled and adjusted for operation under average conditions
of air flow and without any external static pressure. The
motor sheave should be adjusted as required when the unit
is to be operated at other than average air flows and/or with
external static pressures. Adjustment must always be within the
performance range shown on page 17 and the temperature rise
range shown on the unit’s rating plate.
To determine the proper blower speed and motor sheave turns
open, the operating conditions must be known. For example, a
model BDP350 unit, operating with no external static pressure,
(e.g. no ductwork, nozzles, etc.) is to deliver an air volume
of 6481 cfm (cfm = cubic feet per minute). This requires the
unit be supplied with a 5 hp motor, a -207 drive, and the drive
sheave set at 2.5 turns open to achieve a blower speed of 960
6-580.6
11
INSTALLATION
rpm (see performance table for units with or without blower
enclosure, page 17). See "Blower Adjustments" on page 12 for
setting of drive pulley turns open.
If a blower unit is to be used with ductwork or nozzles, etc., the
total external static pressure under which the unit is to operate,
and the required air flow must be known before the unit can be
properly adjusted. Any device added externally to the unit, and
which the air must pass through, causes a resistance to air flow
called pressure loss.
If Modine filters are used, the pressure loss through the filters
is included in the performance data on page 17. If Modine
supplied discharge nozzles are used, the pressure drop of
the nozzles can be found footnoted at the bottom of page
20. If filters, nozzles or ductwork are to be used with the unit,
and they are not supplied by Modine, the design engineer
or installing contractor must determine the pressure loss for
the externally added devices or ductwork to arrive at the total
external static pressure under which the unit is to operate.
Once the total static pressure and the required air flow are
known, the operating speed of the blower can be determined
and the correct motor sheave adjustments made. As an
example, a model BDP350 is to be used with a Modine supplied
blower enclosure and filters attached to ductwork by others.
The unit is to move 6481 cfm of air flow against an external
static pressure of 0.2" W.C, which must be added for the filter
pressure drop for a total of 0.4" W.C. total pressure drop. The
performance table on page 17 for a BDP350, at 6481 cfm and
0.4" W.C. static pressure, shows that the unit will require a 5 hp
motor using a -207 drive, and the motor sheave should be set
at .5 turns open to achieve a blower speed of 1050 rpm.
To Install
1. Remove and discard the motor tie down strap and the
shipping block beneath the belt tension adjusting screw
(Not used on all models.)
2. For 3 and 5 HP motors, affix sheave to the motor shaft and
install motor on the motor mounting bracket. Install belt on
blower and motor sheaves.

4. The blower bearings are lubricated for life; however, before
initial unit operation the blower shaft should be lubricated at
the bearings with SAE 20 oil. This will reduce initial friction
and start the plastic lubricant flowing.
5. Make electrical connections as outlined in the section
"Electrical Connections" on page 11.
Blower Adjustments
Following electrical connections, check blower rotation to assure
blow-through heating. If necessary interchange wiring to reverse
blower rotation. Start fan motor and check blower sheave
RPM with a hand-held or strobe-type tachometer. RPM should
check out with the speeds listed in Performance Data shown
on page 17. A single-speed motor with an adjustable motor
sheave is supplied with these units. If blower fan speed
changes are required, adjust motor sheave as follows:
NOTE: Do not fire unit until blower adjustment has been
made or unit may cycle on limit (overheat) control.
1. Shut-off power before making blower speed adjustments.
Refer to Determining Blower Speed on page 11 and to
Performance Date on page 17 to determine proper blower
RPM.
2. Loosen belt and remove from motor sheave.
3. Loosen set screw on outer side of adjustable motor sheave
(see Figure 12.2).
4. To reduce the speed of the blower, turn outer side of motor
sheave counterclockwise.
5. To increase the speed of the blower, turn outer side of motor
sheave clockwise.
6. Retighten motor sheave set screw, replace belt and retighten
motor base. Adjust motor adjusting screw such that there
is 3/4” belt deflection when pressed with 5 pounds of force
midway between the blower and motor sheaves (see Figure
12.3). Since the belt tension will decrease dramatically after
an initial run-in period, it is necessary to periodically re-check
the tension to assure proper belt adjustment.
7. Check to make certain motor sheave and blower sheave are
aligned. Re-align if necessary.
8. Re-check blower speed after adjustment.
9. Check motor amps. Do not exceed amps shown on motor
nameplate. Slow blower if necessary.
10. Check air temperature rise across unit. Check temperature
rise against values shown in Performance Tables on page
17 to assure actual desired air flow is being achieved.
11. If adjustments are required, recheck motor amps after final
blower speed adjustment.

it is necessary to periodically re-check the tension. Excessive
tension will cause bearing wear and noise.

START-UP PROCEDURE
IMPORTANT
1. To prevent premature heat exchanger failure, observe
heat exchanger tubes. If the bottom of the tubes become
red while blower and furnace are in operation, check to
be sure the blower has been set to the proper rpm for the
application. Refer to page 12 for Blower Adjustments.
2. Start-up and adjustment procedures must be performed by
a qualified service agency.
1. Turn off power to the unit at the disconnect switch. Check that
fuses or circuit breakers are in place and sized correctly. Turn
all hand gas valves to the “OFF” position.
2. Remove electrical junction box cover.
3. Check that the supply voltage matches the unit supply voltage
listed on the Model Identification plate. Verify that all wiring is
secure and properly protected. Trace circuits to insure that the
unit has been wired according to the wiring diagram.
4. Check to insure that the venting system is installed correctly
and free from obstructions.
5. Check to see that there are no obstructions to the intake and
discharge of the unit.
6. For blower units, check the belt tension and sheave alignment.
Refer to Blower Adjustments for proper belt tension.
7. Check bearings for proper lubrication (if applicable).
8. Check to make sure that all filters are in place and that
they are installed properly according to direction of air flow
(if applicable).
9. Perform a visual inspection of the unit to make sure no
damage has occurred during installation. Lower bottom pan
and visually inspect all components in the burner compartment.
Check to ensure all fasteners are in place and the burner
openings are properly aligned with the heat exchanger tubes
and that the gas orifices are centered in the burner inspirator
tube opening opening, as shown in Figure 14.2.
10. Check that all horizontal deflector blades are open a minimum
of 30° as measured from vertical.
11. Turn on power to the unit at the disconnect switch. Check to
insure that the voltage between electrical junction box
terminals T1 and G is 24V.
12. Check the thermostat, ignition control, gas valve, and supply
fan blower motor for electrical operation. If these do not
function, recheck the wiring diagram. Check to insure that
none of the Control Options have tripped.
13. Check the blower wheel for proper direction of rotation when
compared to the air flow direction arrow on the blower housing
(if applicable). Blower wheel rotation, not air movement, must
be checked as some air will be delivered through the unit with
the blower wheel running backwards.
14. For blower units, check the blower speed (rpm). Refer to
Blower Adjustments for modification.
15. Check the motor speed (rpm).
16. Check the motor voltage. On three phase systems, check to
make sure all legs are in balance.
17. Check the motor amp draw to make sure it does not exceed
the motor nameplate rating. On three phase systems, check
all legs to insure system is balanced.
18. Recheck the gas supply pressure at the field installed manual
shut-off valve. The minimum inlet pressure should be 6" W.C.
on natural gas and 11" W.C. on propane gas. The maximum
inlet pressure for either gas is 14" W.C. If inlet pressure
exceeds 14" W.C., a gas pressure regulator must be added
upstream of the combination gas valve.
19. Open the field installed manual gas shut-off valve.
20. Open the manual main gas valve on the combination gas
valve. Call for heat with the thermostat and allow the pilot to
light for intermittent pilot ignition. If the pilot does
not light, purge the pilot line. If air purging is required,
disconnect the pilot line at outlet of pilot valve. In no case
should line be purged into heat exchanger. Check the pilot
flame length (See Pilot Flame Adjustment).
21. Once the pilot has been established, check to make sure that
the main gas valve opens. Check the manifold gas pressure
(See Main Gas Adjustment) and flame length (See Air Shutter
Adjustment) while the supply fan blower is operating. Inspect
the condition of the main flame and if necessary, resolve flame
appearance problems (See Burner Flame Adjustment and
Figures 25.1 through 25.4).
22. Check to insure that gas controls sequence properly (See
Control Operating Sequence). Verify if the unit has any
additional control devices and set according to the
instructions in the Control Options.
23. Once proper operation of the unit has been verified,
remove any jumper wires that were required for testing.
24. Replace the electrical junction box cover.
Pilot Burner Adjustment
The pilot burner is orificed to burn properly with an inlet
pressure of 6-7" W.C. on natural gas and 11-14" W.C. on
propane gas, but final adjustment must be made after
installation. If the pilot flame is too long or large, it is possible
that it may cause soot and/or impinge on the heat exchanger
causing failure. If the pilot flame is shorter than shown, it may
cause poor ignition and result in the controls not opening the
combination gas control. A short flame can be caused by a
dirty pilot orifice. Pilot flame condition should be observed
periodically to assure trouble-free operation.
To Adjust the Pilot Flame
1. Create a call for heat from the thermostat.
2. Remove the cap from the pilot adjustment screw. For
location, see the combination gas control literature supplied
with unit.
3. Adjust the pilot length by turning the screw in or out to
achieve a soft steady flame 3/4" to 1" long and
encompassing 3/8"-1/2" of the tip of the thermocouple or
flame sensing rod (see Figure 13.1).
4. Replace the cap from the pilot adjustment screw.
Figure 13.1 - Correct Pilot Flame
3/4" to 1"
Main Burner Adjustment
The gas pressure regulator (integral to the combination gas
control) is adjusted at the factory for average gas conditions.
It is important that gas be supplied to the unit heater in
accordance with the input rating on the serial plate. Actual
input should be checked and necessary adjustments made
after the unit heater is installed. Over-firing, a result of too
high an input, reduces the life of the appliance and increases
maintenance. Under no circumstances should the input exceed
that shown on the serial plate.
Measuring the manifold pressure is done at the outlet pressure
tap of the gas valve (see Figure 14.1).
To Adjust the Manifold Pressure
1. Move the field installed manual shut-off valve to the “OFF”
position.
2. Remove the 1/8" pipe plug in the pipe tee or gas valve and
attach a water manometer of “U” tube type which is at least
12" high.
6-580.6
13
START-UP PROCEDURE
3. Move the field installed manual gas shut-off valve to the “ON”
position.
4. Create a high fire call for heat from the thermostat.
5. Determine the correct high fire manifold pressure (3.5" W.C.
for natural gas, 10" W.C. for propane gas). Adjust the main
gas pressure regulator spring to achieve the proper manifold
pressure (for location, see the combination gas control
literature supplied with unit).
6. After adjustment, move the field installed manual shut-off
valve to the “OFF” position and replace the 1/8" pipe plug.
7. After the plug is in place, move the field installed manual
shut-off valve to the “ON” position and recheck pipe plugs for
gas leaks with soap solution.

Burner Flame Adjustment
Proper operation provides a soft blue flame with a well-defined
inner core. A lack of primary air will reveal soft yellow-tipped
flames. Excess primary air produces short, well-defined
flames with a tendency to lift off the burner ports. For both
natural and propane gas, the flame may be adjusted by sliding
the manifold. Also, for propane gas, the air shutters can be
adjusted to control the burner flame height. The air shutters
can be accessed by lowering the bottom pan of the unit heater.

Natural Gas Flame Control
Control of burner flames on unit heaters utilizing natural gas is
achieved by resetting the manifold position to either increase
or decrease primary combustion air. Prior to flame adjustment,
operate unit heater for about fifteen minutes. The main burner
flame can be viewed after loosening and pushing aside the gas
designation disc on the back of the unit.
To increase primary air, loosen the manifold mounting screws
and move the manifold away from the burner until the yellowtipped flames disappear (see Figure 14.2). To decrease primary
air, move manifold closer to the burner until flames no longer lift
from burner ports, but being careful not to cause yellow tipping.
Retighten manifold mounting screws after adjustment.
Propane Gas Flame Control
An optimum flame will show a slight yellow tip. Prior to flame
adjustment, operate heater for at least fifteen minutes. Loosen
air shutter set screws and move the air shutters away from the
manifold to reduce the primary air until the yellow flame tips
appear (see Figure 14.3). Then increase the primary air until
yellow tips diminish and a clean blue flame with a well defined
inner cone appears.
It may also be necessary to adjust the manifold position in
addition to adjusting air shutters to obtain proper flame. Follow
the instructions under "Natural Gas Flame Control" for adjusting
the manifold.

Control Operating Sequence
All units are supplied with intermittent pilot systems with
continuous retry control as standard. For intermittent pilot
systems, both the main burner and pilot are turned off 100%
when the thermostat is satisfied. For all units, the system
will attempt to light the pilot for 70 seconds. If the pilot is not
sensed, the ignition control will wait approximately 6 minutes
with the combination gas control closed and no spark. After 6
minutes, the cycle will begin again. After 3 cycles, some ignition
controllers lockout for approximately 1 hour before the cycle
begins again. This will continue indefinitely until the pilot flame
is sensed or power is interrupted to the system. Refer to Table
12.1 for control code descriptions. Specific descriptions of the
control sequence for different control codes are shown below.
1. The thermostat calls for heat.
2. The power exhauster relay is energized starting the power
exhauster motor. Once the motor has reached full speed, the
differential pressure switch closes.
3. The pilot valve opens and the ignitor sparks for 70 seconds
in an attempt to light the pilot.
4. Once the pilot is lit, the flame sensor proves the pilot and
stops the ignitor from sparking.
5. On single stage units, the main gas valve is opened and the
main burner is lit to 100% full fire. On two stage units, the
gas valve may open at either 50% or 100%, depending on
what the two stage thermostat is calling for.
6. The air mover starts after 30 to 90 seconds to allow the heat
exchanger to warm up.
7. The unit continues to operate until the thermostat is satisfied, at
which time both the main and pilot valves close 100%.
8. The air mover stops after 30 to 90 seconds to remove
residual heat from the heat exchanger.

All units include the standard (STD) features. The unit must be
reviewed to determine the optional (OPT) features that may
have been supplied with the unit.
(1) Gas Valve
a) Single Stage Gas Valve - (STD)
The main gas valve provides the pilot, regulator, main gas,
and manual shutoff functions. For additional information,
see the supplier literature included with the unit.
b) Two Stage Gas Valve - (OPT)
The two stage gas valve provides the pilot, regulator, main
gas (100% and 50% fire), and manual shutoff functions.
For additional information, see the supplier literature
included with the unit.
(2) Ignition controller - (STD)
The ignition controller is factory installed on the back of the unit
heater with the spark igniter and sensor located on the burner.
For additional information, refer to “Control Operating Sequence”
on page 14 and the supplier literature included with the unit.
(3) Time Delay Relay - (STD)
(6) High Limit Switch - (STD)
The automatic reset high limit switch is factory installed on
the left side (air blowing at you) of the unit heater. If the limit
temperature is exceeded, the gas controls are de-energized
until the switch is cooled.
(7) Pressure Switch (STD)
A automatic reset vent pressure switch is designed to prevent
operation of the main burner if there is restricted venting of
flue products. This restriction may occur due to an improper
vent diameter, long vent runs, un-approved vent terminal, high
winds, high negative pressure within space, etc. After the cause
of the restriction has been corrected, the pressure switch will
reset automatically. See Troubleshooting section for more
information.
(8) Power Exhauster (STD)
All power vented unit heaters are supplied with a round vent
pipe connection. Some models may require the use of a vent
transition from the power exhauster outlet to the vent pipe (see
Table 6.1). The power exhauster may be rotated 180° to allow
for various venting directions.
The time delay relay is factory installed in electrical junction
box and controls propeller/blower motor function. For singlephase units below 2 Hp, the time delay relay controls the motor
directly. For single-phase units 2 Hp and greater and all three
phase units, the time delay relay controls the motor starter. For
additional information, refer to “Control Operating Sequence”
on page 14.
(9) Blower Motor - (STD on BDP models only)
(4) Low Voltage Terminal Board - (STD)
Table 15.1 - Control Descriptions - Models PDP and BDP
The low voltage terminal board is located in electrical junction
box. The terminal board is labeled to match the electrical
wiring diagram provided with the unit. All low voltage field
wiring connections should be made to the exposed side of the
terminal board (exterior of electrical junction box) to prevent
miswiring by modifying the factory wiring which is inside the
electrical junction box.
The blower motor can be provided in a variety of supply
voltages and motor horsepowers. Refer to the model
nomenclature to determine the motor provided. The blower
motor is supplied with an adjustable sheave that can be used
to increase/decrease the blower RPM. For instructions on
changing the blower RPM, refer to Blower Adjustments.

➀ All motors are totally enclosed and all single phase motors have built-in thermal overload protection.
➁ Ratings shown are for elevations up to 2,000 ft. For elevations above 2,000', ratings should be reduced at the rate of 4% for each 1,000' above sea level.
(In Canada see rating plate.) Reduction of ratings requires use of a high altitude kit.
➂ Data taken at 55°F air temperature rise. At 65°F ambient and unit fired at full-rated input. Mounting height as measured from bottom of unit, and without deflector hoods.
➃ A transformer may not be required. 115V/1φ power may be obtained from the following electrical distribution systems: 230/1φ 3-wire, 230/3φ
4-wire, 208/3φ 4-wire and 208/1φ 3-wire (from 208V wye connected transformer). Please consult the job site electrician to determine applicability.
➄ Unit power code must match building supply voltage, control voltage must match unit power.
➅ For CSA Canada certification, step down transformer may be required to be factory installed (Blower Models Only).

For elevations over 2000’, output needs to be
reduced 4% for each 1000' above sea level.
(Does not apply in Canada - see rating plate)
➁ Sheave turns open are approximate. For proper
operation, check blower rpm
➂ Models not shown use same HP and drive
numbers as cataloged
➃ Performance is the same; motor sheave
accommodates larger shaft. When ordering
230/460V (1 & 1-1/2 HP) or 575V, specify the
listed 230/460V (1 & 1-1/2 HP) or 575V drive.
➀ Outputs shown are for elevations up to 2000'.

The above table is based on an inlet air temperature of 70°F and an air temperature rise of 55°F. Air deflectors on, 40° and 90°
discharge nozzles set perpendicular to the face of the air discharge opening. On 5-way nozzles all air deflectors set perpendicular
to floor. Static pressure measured at 0.1" W.C. for 90° nozzle, 0.2" W.C. for 40° downward and 5-way nozzle, and 0.3" W.C. for 40°
splitter nozzle. Outlet velocities are approximately 1750 FPM for the 40° nozzles, 1000 FPM for the 90° nozzle and 1300 FPM for
5-way. For motor size, drive and blower rpm refer to page 17. Mounting height measured from bottom of unit.

MAINTENANCE
Gas Piping & Controls
WARNING
When servicing or repairing this equipment, use only factoryapproved service replacement parts. A complete replacement
parts list may be obtained by contacting the factory. Refer to
the rating plate on the appliance for complete appliance model
number, serial number, and company address. Any substitution
of parts or controls not approved by the factory will be at the
owner’s risk.
CAUTION
1. Service or repair of this equipment must be performed by a
qualified service agency.
2. Do not attempt to reuse any mechanical or electrical
controllers which have been wet. Replace defective controller.
NOTE: To check most of the Possible Remedies in the
troubleshooting guide listed in Table 24.1, refer to the applicable
sections of the manual.
General Maintenance
The unit and venting system must be checked once a year by
a qualified service technician.
General Unit
When providing annual maintenance for the unit heater, keep
the unit free from dust, dirt, grease and foreign matter. Pay
particular attention to:
1. The combustion air and exhaust vent piping.
2. The burner ports and pilot burner orifices (avoid the use of
hard, sharp instruments capable of damaging surfaces for
cleaning these ports). To check the burner port and pilot
burner orifice, see Burner and Pilot Assembly Removal.
3. The air shutters and main burner orifices (avoid the use of
hard, sharp instruments capable of damaging surfaces for
cleaning these orifices). To check the air shutters and main
burner orifices, see for Manifold Assembly Removal.
Check the motor for lubrication if the motor is not permanently
lubricated. Inspect the fan for damage and fit on motor shaft.
Clean any dust, dirt or foreign matter from the fan blades.
Blower Assembly
The blower assembly includes the bearings, drive sheaves and
belts. Blower bearings should be checked and lubricated based
on the blower manufacturer’s recommendations. Bearings
should also be checked for any unusual wear and replaced if
needed.
Drive sheaves should be checked at the same time the
bearings are inspected. Check to make sure the sheaves are
in alignment and are securely fastened to the blower and motor
shafts.
Belt tension should be rechecked shortly after the unit has been
installed to check for belt stretching. After the initial start-up,
monthly checks are recommended.
1. Shut off gas and electric supply.
2. Lower bottom pan to expose burner and manifold (see
Figure 14.2).
3. Disconnect pilot tubing and thermocouple lead (or ignition
cable) at the combination gas control (and ignition control).
4. Disconnect control wires for the combination gas control.
5. Disconnect gas manifold at ground union joint.
6. Remove the two screws holding the manifold to the heat
exchanger support.
7. Clean the orifices and adjust the air shutters as necessary.
8. Follow steps 2-6 in reverse order to install the manifold
assembly.
9. Turn on the electric and gas supply.
10. Check the ground union joint for leaks with a soap
solution. Tighten if necessary.
Burner and Pilot Assembly Removal
To remove the burner:
5. The heat exchanger should be checked annually for cracks
and discoloration of the tubes. If a crack is detected, the
heat exchanger should be replaced before the unit is put
back into service. If the tubes are dark gray, airflow across
the heat exchanger should be checked to insure that a
blockage has not occurred or the blower is operating
properly.
The electrical wiring should be checked annually for loose
connections or deteriorated insulation.
Propeller Assembly
To remove the manifold:
Before any service, BE SURE TO TURN OFF GAS AT THE
MANUAL SHUT-OFF VALVE AHEAD OF THE COMBINATION
GAS CONTROL AND TURN OFF ALL ELECTRIC POWER
TO THE HEATER.
Electrical Wiring
The gas controls should be checked to insure that the unit is
operating properly.
Manifold Assembly Removal
All installation and service of these units must be
performed by a qualified installation and service agency.
4. The heat exchanger. Clean tubes from the bottom with a
stiff non-wire brush.
The gas valves and piping should be checked annually for
general cleanliness and tightness.
1. Shut off gas and electric supply.
