LOCATIONS
1. This furnace must be installed on an outside wall and vented
to the outside. If possible, this wall should be on the side of
the house that receives the least amount of wind since strong
gusting winds could cause pilot outage.
2. For most efficient performance, locate furnace as centrally
as possible in the area to be heated.
3. The furnace can be installed flush against a wall or recessed
up to 10” maximum. For proper combustion, make sure
unit is level front to back and side-to-side.
4. Do not install the furnace in a closet, alcove or small hallway
where the furnace could be isolated from the space to be
heated by closing a door.
5. Be sure the vent cap will have the proper clearances (See
Figure 2).
6. Check inside the wall to make sure there are no obstacles
such as water pipes, electric wiring, etc. which could
interfere with the installation of the furnace or vent tubes.
7. Be sure to maintain adequate accessibility clearances for
servicing and proper operation.
8. If the furnace is installed in a basement, a 12” clearance
must be maintained between ground level and the bottom
of the vent cap. Do not install furnace where vent cap will
terminate in a window well or any other opening below
ground level.
INSTALLATION
ELECTRICAL ROUGH-IN
For convenience, this furnace is equipped with a three-prong
power cord located on the top left of heater. The 115V wiring
should be brought in on the left side terminating in a receptacle
box (not provided). Consult local codes or ordinances. (For
Amps, see Page 2/Specifications and Dimensions).
ROUGH-IN GAS SUPPLY
Install a 1/2 inch diameter gas supply line. The gas line can
enter the cabinet through the right side or bottom (See Figure
3). The gas line must have an individual manual shut off valve.
Also, you must install a drip leg and provide a 1/8” N.P.T.
plugged tapping, accessible for test gauge connection,
immediately upstream of the gas supply connection to the
furnace (See Figure 4).

LOCATE VENT OPENING
After the location of the heater has been determined, the
opening for the vent pipe should be cut. If the heater is to be
recessed, cut out opening for heater between studs on the
interior wall and cut out the floor plate between the studs, so
heater will set flat on floor as all dimensions are given from
a finished floor. The height of the cut out for a 40,000 BTU
model is 78-5/8”, for the 55,000 and 62,500 models the cut
out height is 87-5/16”. NOTE: This dimension may be
increased to allow more room for installation and making
the wiring connection, then refinished.
Next, cut out a 9-1/4” opening in exterior wall for the vent
tubes to pass through. The center of opening for the 40,000
BTU furnace is 59”, the center for opening for 55,000 and
62,500 BTU furnaces is 68-1/2”. See Figure 5, on Page 6.
If the heater is to be surfaced mounted, cut out 9-1/4” opening
through the interior and exterior wall. The center of cut out
will be 59” for 40,000 BTU and 68-1/2” for 55,000 and
62,500 BTU models. Be sure both cutouts are level with
each other.

INSTALLING THE FURNACE
The vent system supplied with this furnace will accommodate
walls ¾” (when recessed) up to 12” thick. Use only the
exhaust tube, air intake tube and vent cap supplied with
heater. Do not attempt to lengthen the exhaust or air intake
tubes, this could cause an imbalance in the heater resulting
in poor performance and pilot outage (See Figure 6).
Measure exact distance “X” between surface on which back
of cabinet will rest (inside of recessed cavity or face of wall
when freestanding) and the outside wall surface (see Figure
6).
Inlet Air Tube “A” – Measuring from gasketed surface,
mark and cut pipe same as dimension “X”. Remove any
burrs.
Vent Exhaust Tube “B” – Measuring from gasketed
surface, mark and cut pipe 1-3/4” greater than dimension
“X”. Remove any burrs.
Fasten vent exhaust tube “B” to heat exchanger collar and
Inlet Air Tube “A” to flange on back of furnace using 16 #
3/8 screws (“C”) provided. Be sure gaskets are in place and
not damaged. Anytime the vent pipes are removed check
and replace gaskets (if necessary). Failure to replace missing
or damaged gaskets may expose homeowner to life
threatening conditions.
Secure furnace in place using 2 holes provided in bottom of
casing. NOTE: Make sure both tubes are centered in cut
out. Slide the vent cap onto the pipes extending from the
back of the furnace. A rotating or twisting motion will ease
this installation. Secure vent cap and vent cap spacer plate
to wall causing the vent tubes to have a slight downward
pitch. This will prevent water from entering. Anchors (not
provided) may be required. Caulk around vent cap spacer
plate with caulking provided. NOTE: Some framing may
be necessary to provide a flat surface against the vent cap
spacer plate and to prevent rain from entering the wall
opening.
Page 7
GAS CONNECTION
Make the gas connection between the manual shut off valve
and the furnace gas control valve with approved ½”
connectors. Compounds used on threaded joints of gas
piping shall be approved for use with L.P. gas. The gas
lines must be checked for leaks by the installer with soapy
water or liquid detergent, never use an open flame. If
connections are not exposed, a pressure test must be run.
Be sure to disconnect the gas supply line from the appliance
valve before pressure testing. The manifold pressure is
pre-set at the factory and should be 3.5” w.c. for Natural
Gas and 10” w.c. for L.P. Gas. The minimum inlet pressure
for Natural Gas is 4.5” w.c. and 11” w.c. for L.P. Gas, “for
purpose of input adjustment”. The maximum inlet pressure
should never exceed 7.0” w.c. on Natural Gas or 14” w.c.
on L.P. Gas.
THERMOSTAT INSTALLATION
Follow the instructions included with the thermostat. Select
a location for the thermostat on an inside wall approximately
5 feet above the floor where it won’t be affected by heat or
cold sources such as direct sunlight, televisions, fireplaces,
hidden hot or cold water pipes, drafts, etc., and a minimum
of 4’ from the heater. The thermostat must never be placed
in an adjacent room. Connect thermostat wires to
thermostat and mount to wall. Run wire to furnace and
make connections to thermostat wires coming out of top of
furnace. Use insulated staples (provided) to secure wire to
wall.
OPERATION
This unit uses a “step action” valve. When the heater comes
on initially, it operates at a lower pressure to insure proper,
quiet, ignition. After 20 seconds or less, it automatically
steps up to the proper manifold pressure with a discernable
increase in flame height.
After the heat exchanger has warmed sufficiently, the fan
will automatically come on to efficiently transfer the heat
into the room. NOTE: All but the 40,000 BTU unit (which
is one-speed) have an automatic two-speed fan.

TO REMOVE MAIN BURNER FOR
PILOT ADJUSTMENT
INSPECTION AND CLEANING
Locate the pilot adjustment screw on the valve. The
pilot flame should surround at least the top 3/8” of the
powerpile (pilot generator) or flame sensor (see Figure
7). The pilot is unregulated so it will be operating at
inlet line pressure (Max. 7” w.c. for Natural Gas and
11” w.c. for Propane). To decrease the pilot flame,
turn the screw clockwise
(approximately six full
turns to bottom of pilot light channel) until you produce
sufficient flame at the minimum noise level.

11. Follow lighting instructions, and replace lower grille.
It is recommended that the furnace and all components be inspected
at least annually by a qualified service person. This should include
the burner, pilot, heat exchanger, and vent system. Be sure that
the flow of combustion and ventilation air is not obstructed.
IMPORTANT: Keep burner and control compartment clean.
Vacuum control compartment at the start of the heating season
and as often as needed.

The burner flame may be observed by raising the sight glass cover.
A proper flame will have a dark blue inner mantle that sits right
on top of the burners with a lighter blue outer mantle rising above
the burner (See Figure 8). There may be some yellow where the
pilot flame and burner flame meet. There is no primary air
adjustment on the burner, and proper flame is assured since the
correct manifold pressure and orificing has been done at the factory.
NOTE: It is advised that the burner flames be checked at least
twice during the heating season for any changes in burner flame
characteristics. The appliance area must be kept clear and free
from combustible materials, gasoline, and other flammable vapors
and liquids. This heater comes from the factory with the proper
burner orifice for elevations up to 2,000 feet. Heaters installed
above 2,000 feet must be derated 4% for every 1,000 feet. For the
proper orifice size, find the Model Number and elevation on the
orifice chart. Replace burner orifice.

MANUAL RESET SWITCH
For your safety this furnace is equipped with a manual reset limit switch. In case of failure by the primary limit switch, this
switch will shut the valve down completely before unsafe temperatures are reached. After a cool down period, switch must be
manually reset. If outages persist, call a qualified service person.
MAINTENANCE INSTRUCTION
For proper and safe operation, keep furnace and furnace area clean.
At regular intervals turn control valve off, let cool and clean inside
control compartment. To clean cabinet, use only a damp cloth.
Do not use any kind of solvent or cleaning fluid that could leave a
residue or invisible coating that would burn or give off fumes
when furnace is turned on.
OIL TUBE
Have the furnace checked, cleaned, and repaired by a qualified
service person for vent system, pilot and burner operation prior
to use each year.
The bearings of the fan motor should be oiled every twelve (12)
months with S.A.E. 20 oil. (See Figure 10).
Follow a regular service and maintenance schedule for safe and
efficient operation.
FIGURE 10
Examine the venting system as a routine part of the safety
performance check on an annual basis.

IMPORTANT SAFETY BULLETIN ON YOUR GAS CONTROL AND PILOT LIGHT
SYSTEM FOR HEATING EQUIPMENT
WHAT YOU DON’T KNOW CAN HURT YOU.
Your pilot light system has been designed for safe and reliable operation. Although safety mechanisms are built-in,
the potential for hazard exists. This information is intended to help you avoid these hazards.
YOUR GAS CONTROL AND PILOT LIGHT
SYSTEM
Your gas control and pilot light system has a safety
device whose purpose is to shut-off the gas supply
to the appliance if the pilot light goes out. If you
have trouble lighting the pilot or keeping it lit, it
may mean that this safety device is warning you
that there is a problem with your system.
Inspection and repairs or replacement must be
made by a trained gas service technician.
WHAT TO DO IF YOU SMELL GAS . . .
• Do not try to light any appliance.
• Do not touch any electrical switch; do
not use any phone in your building.
• Immediately call your gas supplier from
a neighbor’s phone. Follow the gas
supplier’s instructions.
• If you cannot reach your gas supplier,
call the fire department.
Installation and service must be performed
by a qualified installer, service agency or the
gas supplier.
Do not store or use gasoline or other
flammable vapors and liquids in the vicinity
of this or any other appliance.
TAMPERING IS DANGEROUS
The pilot safety system may also not work if you
do not follow the lighting instructions carefully or
if you tamper with the gas control that you use to
light the pilot. Tampering with the gas control,
particularly with tools, can damage the safety
mechanism in the control and can allow gas to leak.
This can result in a fire or explosion causing
property damage, personal injury or death.
IF YOU SMELL GAS, DON’T LIGHT IT
IF YOU CAN’T LIGHT IT,
DON’T FIGHT IT!
THIS IS NOT AN ADVERTISEMENT
CRITICAL SAFETY POINTS TO
REMEMBER . . .
• Your gas has been odorized so that you
can smell it. Always smell around for
gas before lighting your appliance.
• Sniff for L.P.-gas at floor level. LP-gas is
heavier than air and may temporarily
exist at floor level.
•
If you smell gas, do not attempt to light
the pilot. Do not cause a spark by
turning on or off electrical switches or
appliances or by using the phone. Turn
off the gas to the appliances and call
your gas supplier from another location.
•
If your gas control has gotten wet as the
result of flooding or other wetting, it
must be replaced immediately by a
trained gas service technician. Water
can lead to damage of the internal safety
mechanism in the gas control and can
create a hazardous condition.
