FIRE AND EXPLOSION HAZARD
Failure to follow this warning could result in personal iniury
and/or death.
NEVER test for gas leaks with an open flame. Use a
commercially available soap solution made specifically for
the detection of leaks to check all connections. A fire or
explosion may result causing property damage, personal
iniury or loss of life.
RISQUE D'EXPLOSION ET D'INCENDIE
Le fait de ne pas suivre cet avertissement pourrait entra_ner des
dommages corporels et / ou la mort.
Ne jamais exanfiner pour les fuites de gaz avec une flamme
vive. Utilisez plut6t un savon fair specifiquement pour la
d_tection des fuites de gaz pour verifier tousles connections.
Un incendie ou une explosion peut entrainer des dommages
materiels, des blessures ou la mort.
FIRE, EXPLOSION, ELECTRICAL SHOCK
HAZARD
Failure to follow this warning could result in personal
iniury, death or property damage.
Gas supply MUST be shut off before disconnecting
electrical power and proceeding with conversion.
ELECTRICAL SHOCK, FIRE OR EXPLOSION
HAZARD
Failure to follow this warning could result in personal
iniury, death or property damage.
Before installing, modifying, or servicing system, main
electrical disconnect switch nmst be in the OFF position and
install a lockout tag. There may be more than one
disconnect switch. Lock out and tag switch with a suitable
warning label. Verify proper operation after servicing.

GAS
Be sure main gas and electric supplies to furnace are off.
Remove l/8-in. (3 ram) pipe plug from manifold pressure
tap on downstream side of gas valve.
Attach manometer to manifold pressure tap on gas valve.
Turn gas supply manual shutoff valve to ON position.
Turn furnace gas valve switch to ON position.
Check all threaded pipe connections for gas leaks.
Turn on furnace power supply.
INPUT RATE INFORMATION
The gas input rate for propane is the same as for natural gas. See
furnace rating plate for input rate. The input rate for propane is
deternfined by manifold pressure and orifice size.
The gas valve nmst be set for Low Heat first and then set for High
Heat on 2-stage and variable-speed furnaces. Furnace gas input
rate on rating plate is for installations at altitudes up to 2000 ft.
(610 M).
In the U.S.A., the input rating for altitudes above 2000 ft. (610
M) must be reduced by 2 percent for each 1000 ft. (305 M) above
sea level.
In Canada, the input rating must be derated by 5 percent for
altitudes of 2000 ft. (610 M) to 4500 ft. (1372 M) above sea
level.
The Conversion Kit Rating Plate accounts for high altitude
derate.

1. Verify SW1-2 on furnace control is turned "ON". See Fig.
45.
2. Jumper R and W/W1 thermostat connections to call for
heat.
3. Check manifold orifices for gas leaks when main burners
ignite.
4. Adjust gas manifold pressure, (Refer to conversion kit rat-
ing plate 337704-204,
5. Remove caps that conceal adjustment screws for gas valve
regulators, (See Fig. 43.)
