10. Turn gas supply manual shutoff valve to OFF position.
11. Turn off furnace power supply.
12. Remove manometer and on some models remove
pressure tap fitting.
13. On some models, apply pipe dope sparingly to the end of
inlet gas pipe plug and install into the unused end of
1/8 − in. (3 mm) tee. Or, on some models, tighten set screw
on inlet tower pressure tap with a 3/32 − in. hex wrench.
See Figure 8 .

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.
1. Be sure main gas and electric supplies to furnace are off.
2. On some models, remove 1/8-in. (3 mm) NPT pipe plug
from manifold pressure tap on outlet end of gas valve. Or,
on some models, loosen set screw on manifold tower
pressure tap no more than one full turn with a 3/32 − in. hex
wrench.
3. Attach manometer to manifold pressure tap on gas valve.
(See Figure 8 )
4. Turn gas supply manual shutoff valve to ON position.
5. Turn furnace gas valve switch to ON position.
GAS INPUT RATE INFORMATION
See furnace rating plate on blower door for input rate. The input
rate for natural gas is determined by manifold pressure and
orifice size.
Determine natural gas orifice size and manifold pressure for
correct input at installed altitude by using Table 3 .
1. Obtain yearly heat − value average (at installed altitude) for
local gas supply.
2. Obtain yearly specific − gravity average for local gas supply.
3. Find installation altitude in Table 3 .
For Canada altitudes of 2000 to 4500 ft., use U.S.A. Altitudes of
2001 to 3000 ft. in
Table 3 .
4. Find closest natural gas heat value and specific gravity in
Table 3 .
5. Follow heat − value line and specific − gravity line to point of
intersection to find orifice size and manifold pressure
setting.
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.

AVERTISSEMENT
RISQUE D’EXPLOSION ET D’INCENDIE
Le fait de ne pas suivre cet avertissement pourrait entraîner
des dommages corporels et / ou la mort.
Ne jamais examiner pour les fuites de gaz avec une flamme
vive. Utilisez plutôt un savon fait specifiquement pour la
détection des fuites de gaz pour verifier tous les connections.
Un incendie ou une explosion peut entrainer des dommages
matériels, des blessures ou la mort.
1. Jumper R and W thermostat connections to call for heat.
(See Figure 13 )
2. Check manifold orifices for gas leaks when main burners
ignite.
3. Adjust gas manifold pressure. Refer to Table 3 .
4. Remove cap that conceals the gas valve regulator
adjustment screw.
5. Turn adjusting screw counterclockwise (out) to decrease
manifold pressure or clockwise (in) to increase manifold
pressure.
6. Replace gas valve regulator seal cap.
7. Verify manifold pressure is correct. Refer to
Table 3 .

Gas valve regulator seal cap MUST be in place when checking
input rate. When correct input is obtained, main burner flame
should be clear blue, almost transparent (See
Figure 11 ). Be
sure regulator seal cap is in place when finished.
8. Remove jumper across R and W thermostat connections
to terminate call for heat.
9. Turn furnace gas valve control switch or control knob to
OFF position.
