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 efcient performance, locate furnace as centrally as
possible in the area to be heated.
3. The furnace can be installed ush 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 2a)
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 3 / Specications 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).
The furnace and its individual shut off valve must be disconnected from
the gas supply piping system during any pressure testing of that system
at test pressures in excess of ½ psig (3.5kPa). The furnace must be
isolated from the gas supply piping system by closing its individual
manual shut off valve during any pressure testing of the gas supply
piping system at test pressures equal to or less than ½ psig (3.5kPa).

INSTALLATION
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 oor plate between the studs, so heater will set at on oor as all
dimensions are given from a nished oor. The height of the cut out
for a 40,000 BTU model is 78-5/8”, for the 55,000 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
renished.
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 BTU furnace 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 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).
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 Propane gas. The gas lines must be checked for leaks
by the installer with soapy water or liquid detergent, never use
an open ame. 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 Propane Gas. The minimum inlet pressure for Natural
Gas is 4.5” w.c. and 11” w.c. for Propane 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 Propane 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 oor where it won’t be affected by heat or cold sources
such as direct sunlight, televisions, replaces, 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 heater is equipped with a slow opening gas control. On a call
for heat the gas valve does not snap-open to full manifold pressure,
but opens with a gradual increase to normal manifold pressure. The
time lapse from the call for heat to normal operating pressure is two
to ve seconds. The slow open feature assures a safe, less noisy
ignition.

MAINTENANCE
PILOT ADJUSTMENT
1. Locate the pilot adjustment screw on
the valve.
2. The pilot ame should surround at
least the top 3/8” of the powerpile
(pilot generator) or ame sensor (see
Figure 8).
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).
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
qualied service person.
TO DECREASE
THE PILOT FLAME
Turn the screw clockwise.
(Approximately six full turns to bottom of pilot
light channel) until you produce a sufcient
ame at the minimum noise level.
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 uid that could leave a residue or
invisible coating that would burn or give off fumes when furnace is turned on.
Have the furnace checked, cleaned, and repaired by a qualied service technician, including
the 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 7).
Follow a regular service and maintenance schedule for safe and efcient operation.
Examine the venting system as a routine part of the safety performance check on an
annual basis.

TO REMOVE MAIN BURNER
FOR INSPECTION & CLEANING
1. Turn thermostat to lowest setting and allow
the furnace to cool.
2. Turn off all electric power to furnace.
3. Remove lower grille.
4. Disconnect gas supply to valve.
5. Disconnect wires from gas valve.
6. Remove 15 screws holding burner door to
burner box. Pull door forward to remove
complete burner, gas valve assembly.
7. After inspecting and cleaning, place burner
assembly back into burner box and tighten
15 screws.
NOTE: Be sure door gasket is not damaged
and will effect a proper seal or pilot outage
will occur.
8. Connect wires back to valve.
9. Connect gas supply back to valve.
10. Turn on electric to furnace.
11. Follow lighting instructions, and replace
lower grille.
It is recommended that the furnace and all
components be inspected at least annually by a
qualied service technician. This should include
the burner, pilot, heat exchanger, and vent system.
Be sure that the ow of combustion and ventilation
air is not obstructed.
IMPORTANT: Keep burner & control compartment
clean. Vacuum control compartment at the start of
the heating season and as often as needed.
PROPER BURNER FLAME
The burner ame may be observed by raising the sight glass cover. A proper
ame 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 9 on page 11).
There may be some yellow where the pilot ame and burner ame meet. There
is no primary air adjustment on the burner, and proper ame is assured since the
correct manifold pressure and oricing has been done at the factory. NOTE: It
is advised that the burner ames be checked at least twice during the heating
season for any changes in burner ame characteristics.
The appliance area must be kept clear and free from combustible materials,
gasoline, and other ammable vapors and liquids. This appliance is equipped
only for altitudes 0-2,000 feet. Heaters installed above 2,000 feet must be derated
4% for every 1,000 feet. For the proper orice size, nd the Model Number and
elevation on the orice chart. Replace burner orice. Orice change must be
completed by a qualied installer or service technician.
