6. Adjust low-heat manifold pressure for propane gas. (See

Fig. 43.)

7. Turn low-heat adjusting screw counterclockwise (out) to

decrease input rate or clockwise (in) to increase input rate.

NOTE: When correct input is obtained, main burner flame

should be clear blue, almost transparent (see Fig. 47).

8. Jumper R, W/W1 and W2 on control center thermostat

connections. This keeps fltrnace locked in high-heat oper-

ation.

9. Adjust high-heat manifold pressure for propane gas.

10. Turn high-heat adjusting screw counterclockwise (out) to

decrease input rate or clockwise (in) to increase input rate.

11. Replace caps that conceal gas valve regulator adjustment

screws.

NOTE: When correct input is obtained, main burner flame

should be clear blue, almost transparent. (See Fig. 47).

12. Remove jumper across R, Wl, and W2 after high-heat ad-

justment to terminate call for heat.

13. Turn setup switch SWl-2 on fltrnace control to OFF posi-

tion.

14. Turn fltrnace gas valve switch to OFF position.

15. Turn off fltrnace power supply.

16. Remove manometer and re-install manifold pressure tap

plug.

17. Turn fltrnace gas valve switch to ON position.

18. Turn on fltrnace power supply.

19. Set room thermostat to call for heat.

20. Check pressure tap plug for gas leaks when main burners

ignite.

21. Check for correct burner flame.

22. Observe unit operation through 2 complete heating cycles.

23. See Sequence of Operation in furnace Installation, Start-

Up, and Operating Instructions.

24. Set room thermostat to desired temperature.

25. After making the required manifold pressure adjustments,

check and adjust the furnace temperature rise per the fur-

nace installation instructions,

CHECK LOW GAS PRESSURE SWITCH

The newly installed low gas pressure switch is a safety device

used to guard against adverse burner operating characteristics that

can result from low gas supply pressure. Switch opens at not less

than 6.5 in. W.C. and closes at not greater than 10.2 in. W.C.

This switch also prevents operation when the propane tank level

is low which can result in gas with a high concentration of

impurities, additives, and residues that have settled to the bottom

of the tank. Operation under these conditions can cause harm to

the heat exchanger system. This normally open switch closes

when gas is supplied to gas valve under normal operating

pressure. The closed switch completes control circuit. Should an

interruption or reduction in gas supply occur, the gas pressure at

switch drops below low gas pressure switch setting, and switch

opens. Any interruption in control circuit (in which low gas

pressure switch is wired) quickly closes gas valve and stops gas

flow to burners. When normal gas pressure is restored, the system

must be electrically reset to re-establish normal heating operation.

Before leaving installation, observe unit operation through 2

complete heating cycles. During this time, turn gas supply to gas

valve off just long enough to completely extinguish burner flame,

then instantly restore full gas supply. To ensure proper low gas

pressure switch operation, observe that there is no gas supply to

burners until after hot surface igniter begins glowing.

LABEL APPLICATION

1. Fill in Conversion Responsibility Label 337704-204 and

apply to Blower Access Door of furnace as shown. Date,

name, and address of organization making this conversion

are required.

2. Attach Conversion Rating Plate Label 337704-204 to out-

er door of furnace.

3. Apply Gas Control Conversion Label: For 2-stage J and

G gas valves, use Gas Control Conversion Label

337780-202. (Do not use 337780-203, which is similar.)

For 2-stage E gas valve, use Gas Control Adjustment La-

bel 337780-203. (Do not use 337780-202, which is simil-

ar.)

4. Replace control access door, blower access door and outer

door of furnace.

CHECKOUT

1. Observe unit operation through 2 complete heating cycles.

2. See Sequence of Operation in furnace Installation, Start-

Up, and Operating Instructions.

3. Set room thermostat to desired temperature.
