PROCEDURE 4—INSTALL MANIFOLD ASSEMBLY, ALL FURNACES
1. Reinstall manifold, orifice, and gas-valve assembly in burner box. Ensure manifold seal grommet is installed properly and burners fit over
orifices. Verify Igniter to Burner alignment (See Fig. 31.)
2. Reconnect wires to gas valve. Refer to furnace wiring schematic for proper wire location.
3. Reinstall burner box pressure tube to gas-valve regulator fitting.
4. Apply pipe dope sparingly to end of inlet gas pipe and reconnect gas supply pipe to gas valve using backup wrench on gas valve to prevent
rotation and improper orientation.
NOTE:
Use propane-gas-resistant pipe dope to prevent gas leaks. DO NOT use Teflon tape.
NOTE:
DO NOT reinstall burner enclosure front at this time.
PROCEDURE 5—PRE-ADJUST GAS VALVE
A.
Convert and Pre-Adjust Single Stage Gas Valve
NOTE:
The following furnaces MUST have the regulator spring replaced in the gas valve
1. Be sure main gas and electrical supplies are off.
2. Remove regulator seal cap. (See Fig. 22A and 22B.)
3. Remove adjustment screw and natural gas regulator spring (silver).
4. Install propane gas regulator spring (white) in gas valve.
5. Turn regulator adjustment screw in 6 turns for Fig. 22A and 8.5 turns for Fig. 22B.
NOTE:
DO NOT reinstall regulator seal cap at this time.
B.
Pre-Adjust 2-Stage and Variable Speed Gas Valve
NOTE:
The following furnaces with Fig. D type valves DO NOT need have the regulator spring replaced in the gas valve, but the valve MUST
be pre-adjusted for propane applications. The following furnaces with Fig. 22C type valve MUST have both springs replaced another valve must
be pre-adjusted:
CAUTION: UNIT DAMAGE HAZARD
Failure to follow this caution may result in excess underfire and flashback.
The gas valve must be pre-adjusted before operating on propane gas. If left this way sooting and corrosion will occur leading to early
heat exchanger failure.
