1. Turn Setup Switch SW1 (LHT or TT) on furnace control ON, see
Fig. 22 .
2. Jumper R-W/W1 and R-W2 thermostat connections on control.
3. When main burners ignite, confirm inlet gas pressure is between
4.5-in. w.c. and 13.6-in. w.c.
4. Remove jumper across R-W/W1 and R-W2 thermostat connections
to terminate call for heat.
5. Turn furnace gas valve switch to OFF position.
6. Turn gas supply manual shutoff valve to OFF position.
7. Turn off furnace power supply.
8. Remove manometer and on some models remove pressure tap
fitting.
9. On some models, apply pipe dope sparingly to the end of inlet gas
pipe plug and install into unused end of 1/8-in. (3 mm) tee. Use a
small back-up wrench on tee when tightening gas inlet pipe plug.
Or, on some models, tighten set screw on inlet tower pressure tap
no more than one full turn with a 3/32-in. hex wrench, see Fig. 13
or Fig. 14 .

Motor
1. Enable two-stage thermostat on control board by:
a. For boards with DIP switches, turn SW1-2 on furnace control
ON, see Fig. 23 .
b. For boards with 3 digit, navigate to (
Htt
) and select (
2St
). See
furnace installation manual for additional instructions.
2. Jumper R-W/W1 and R-W2 thermostat connections on control.
3. When main burners ignite, confirm inlet gas pressure is between
4.5-in. w.c. and 13.6-in. w.c.
4. Remove jumper across R-W/W1 and R-W2 thermostat connections
to terminate call for heat.
5. Turn furnace gas valve switch to OFF position.
6. Turn gas supply manual shutoff valve to OFF position.
7. Turn off furnace power supply.
8. Remove manometer and on some models remove pressure tap
fitting.
9. On some models, apply pipe dope sparingly to the end of inlet gas
pipe plug and install into unused end of 1/8-in. (3 mm) tee. Use a
small back-up wrench on tee when tightening gas inlet pipe plug.
Or, on some models, tighten set screw on inlet tower pressure tap
with a 3/32-in. hex wrench, see Fig. 17 .
CHECK FURNACE AND MAKE ADJUSTMENTS
1. Be sure main gas and electric supplies to furnace are off.
2. On some models, remove 1/8-in. (3 mm) pipe plug from manifold
pressure tap on the outlet end of gas valve and insert pressure tap.
Or, on some models, loosen the set screw on manifold tower
pressure tap no more than one full turn with the 3/32-in. hex
wrench.
3. Attach manometer to manifold pressure tap on gas valve, see
Fig. 11 , Fig. 12 , Fig. 13 , Fig. 14 , or Fig. 17 .
4. Turn gas supply manual shutoff valve to ON position.
5. Turn furnace gas valve switch to ON position.
6. Check all threaded pipe connections for gas leaks.
7. Turn on furnace power supply.
GAS INPUT RATE INFORMATION
See furnace rating plates, see Fig. 5 , Fig. 6 , or Fig. 7 , for input rate. The
input rate for natural gas is determined by manifold pressure and orifice
size.
Modulating gas valve must be set for Maximum Heat first and then set
for Minimum heat on Modulating furnaces.
Two-Stage gas valve must be set for High Heat first and then set for Low
Heat on Two-Stage 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. (610M) 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.

WARNING
!
FIRE OR EXPLOSION HAZARD
Failure to follow this warning could result in personal injury, death,
and/or property damage.
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 injury or loss of life.
AVERTISSEMENT
!
RISQUE D’EXPLOSION ET D’INCENDIE
Le non-respect des avertissements de sécurité pourrait d’entraîner des
blessures graves, la mort ou des dommages matériels.
Ne jamais utiliser une flamme nue por vérifier la présence des fuites de
gaz. Pour la vérification de tous les joints, utiliser plutôt une solution
savonneuse commerciale fabriquée spécifiquement pur la détection des
fuites de gaz. Un incendie ou une explosion peut entraîner des
dommages matériels, des blessures ou la mort.
