Attention! The 7/8" (22mm) strain relief bushing is located within
the same yellow envelope as the Installation Instructions and
Owner's Manual.
Attaching Furnace to Wall
When attaching furnace to the wall remove that portion of baseboard
and molding on the wall which is behind the furnace. Attach furnace
to wall, at the outer casing top, with (2) toggle bolts provided and
to floor, at the outer casing bottom, with (2) #10 x 1 1/2" (38mm)
screws provided.
Attention! The screw holes on the outer casing bottom are off-set
above the floor approximately 3/8" (9.5mm). Do not over-tighten
screws and distort the off-set on the outer casing bottom. Distortion
of the outer casing bottom will not allow the lower front panel to be
attached to the furnace.
Gas Supply
Check all local codes for requirements, especially for the size and
type of gas supply line required. On Natural gas lines less than 15'
(4.5m) long, us (1/2" (13mm) pipe; on longer runs, use 3/4" (19mm)
iron pipe or equal. On LP gas lines please consult LP gas supplier.
Installing a New Main Gas Cock
Each appliance should have its own manual gas cock.
A manual main gas cock should be located in the vicinity of the unit.
Where none exists, or where its size or location is not adequate,
contact your local authorized installer for installation or relocation.
Compounds used on threaded joints of gas piping shall be resistant
to the action of liquefied petroleum gases. The gas lines must be
checked for leaks by the installer. This should be done with a soap
solution watching for bubbles on all exposed connections, and if
unexposed, a pressure test should be made.
Never use an exposed flame to check for leaks. Appliance must
be disconnected from piping at inlet of control valve and pipe
capped or plugged for pressure test. Never pressure test with
appliance connected; control valve will sustain damage!
A gas valve and ground joint union should be installed in the gas
line upstream of the gas control to aid in servicing. It is required by
the National Fuel Gas Code that a drip line be installed near the gas
inlet. This should consist of a vertical length of pipe tee connected
into the gas line that is capped on the bottom in which condensation
and foreign particles may collect.

Method of Installing a Tee Fitting Sediment Trap
The use of the following gas connectors is recommended:
–ANS Z21.24 Appliance Connectors of Corrugate Metal Tubing
and Fittings
–ANS Z21.45 Assembled Flexible Appliance Connectors of Other
Than All-Metal Constructions
The above connectors may be used if acceptable by the authority
having jurisdiction.

Pressure Testing of the Gas Supply System
1. To check the inlet pressure to the gas valve, a 1/8" (3mm) N.P.T.
plugged tapping, accessible for test gauge connection, must
be placed immediately upstream of the gas supply connection
to the appliance.
2. The appliance and is individual shutoff valve must be discon-
nected from the gas supply piping system during any pressure
testing of that system at test pressures in excess of 1/2 psig
(3.5 kPa).
3. The appliance must be isolated from the gas supply piping
system by closing its individual manual shutoff valve during
any pressure testing of the gas supply piping system at test
pressures equal to or less than 1/2 psig (3.5 kPa).
Attention! If one of the above procedures results in pressures in
excess of 1/2 psig (14" w.c.) (3.5 kPa) on the appliance gas valve,
it will result in a hazardous condition.
Checking Manifold Pressure
Both Propane and Natural gas valves have a built-in pressure
regulator in the gas valve. Natural gas models will have a manifold
pressure of approximately 4.0" w.c. (.996kPa) at the valve outlet with
the inlet pressure to the valve from a minimum of 5.0" w.c. (1.24kPa).
Propane gas models will have a manifold pressure approximately
10.0" w.c. (2.49kPa) at the valve outlet with the inlet pressure to the
valve from a minimum of 11.0" w.c. (2.739kPa) for the purpose of
input adjustment to a maximum of 13.0" w.c. (3.237kPa).
A 1/8" (3mm) N.P.T. plugged tapping, accessible for test gauge
connection, is located on the outlet side of the gas control.
The built-in regulator comes on at approximately 1/4th pressure
and full on in 10 seconds.

High Altitudes
For altitudes/elevations above 2,000 feet (610m), input ratings should
be reduced at the rate of 4 percent for each 1,000 feet (305m) above
sea level. Canadian High Altitudes for locations having an elevation
above mean sea level between 2,000 feet (610m) and 4,500 feet
(1370m), the manifold pressure is to be decreased from 4.0" w.c.
(.996kPa) to 3.2" (.797kPa) w.c. for Natural Gas and from 10.0" w.c.
(2.49kPa) to 8.0" w.c. (1.992kPa) for Propane Gas.
Piezo Pilot Ignitor Instructions
Depressing the red button completely causes a spark to occur at
the pilot. This is a substitute for a match which requires opening
the pilot hole cover.
To light the pilot, it is important that the electrode be 1/8" (3mm)
from the thermocouple. The spark must occur at the point the
burner flame hits the thermocouple. The end of the electrode will
be red hot with the pilot on.
On a new installation with air in the gas line, it is suggested that a
match be used. The match will light the pilot faster than the piezo
under this condition.
