AGAGC9NPS01D Gas Conversion Kit, Natural to Propane: Installation Instructions
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) 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. 10, Fig. 11, Fig. 12, Fig. 13
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
The gas input rate for propane is the same as for natural gas. See furnace
rating plate (see Fig. 5) for input rate. The input rate for propane 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.

1. Jumper R and W thermostat connections to call for heat (see
Fig. 20).
2. Check manifold orifices for gas leaks when main burners ignite.
3. Adjust gas manifold pressure.
4. Remove cap that conceals 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.
NOTE: 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
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.
10. Turn off furnace power supply.
11. Remove manometer and on some models remove pressure tap
fitting.
12. On some models, apply pipe dope sparingly to end of 1/8-in. (3
mm) pipe plug and install in the manifold pressure tap opening. Or,
on some models, tighten set screw on manifold tower pressure tap
with a 3/32-in. hex wrench (see
13. Turn furnace gas-valve switch to ON position.
14. Turn on furnace power supply.
15. Set room thermostat to call for heat.
16. Check pressure tap plug for gas leaks when main burners ignite.
17. Check for correct burner flame.
18. After making the required manifold pressure adjustments, check
and adjust the furnace temperature rise per the furnace installation
instructions.
Fixed-Speed Blower (FCT), Two-Stage Gas Valve
1. Verify SW1 (LHT or TT) on furnace control is turned "ON" (see
Fig. 22).
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.
5. Remove caps that conceal adjustment screws for gas valve
regulators (see Fig. 12
6. Adjust low heat input rate manifold pressure for propane gas.
7. Turn low heat adjusting screw counterclockwise (out) to decrease
input rate or clockwise (in) to increase input rate.
8. When correct input is obtained, main burner flame should be clear
blue, almost transparent (see
9. Jumper R and W/W1 and W2 on control center thermostat
connections. This keeps furnace locked in high heat operation.
10. Adjust high heat input rate manifold pressure for propane gas.
11. Turn high heat adjusting screw counterclockwise (out) to decrease
input rate or clockwise (in) to increase input rate.
12. Replace caps that conceal gas valve regulator adjustment screws.
13. When correct input is obtained, main burner flame should be clear
blue, almost transparent (see
14. Remove jumper across R, W1, and W2 after high heat adjustment
to terminate call for heat.
15. Turn setup switch SW1 (TT) on furnace control to OFF position.
16. Turn furnace gas-valve switch to OFF position.
17. Turn off furnace power supply.
18. Remove manometer from the manifold pressure tap of the gas
valve.
19. On some models, apply pipe dope sparingly to end of 1/8-in. (3
mm) pipe plug and install in the manifold pressure tap opening. Or,
on some models, tighten set screw on manifold tower pressure tap
with a 3/32-in. hex wrench (see
20. Turn on furnace power supply.
21. Set room thermostat to call for heat.
22. Check pressure tap plug for gas leaks when main burners ignite.
