CONVERT GAS VALVE

A93347

UNIT DAMAGE HAZARD

Failure to follow this caution may result in unit damage

The G or J gas valve must be converted and pre-adjusted

before operating on propane gas. The E valves must be

pre-adjusted before operating on propane gas. If left this

way, sooting and corrosion will occur leading to early heat

exchanger failure.

FIRE, EXPLOSION, ELECTRICAL SHOCK

HAZARD

Failure to follow this warning could result in personal

iniury, death or property damage.

Gas supply MUST be shut off before disconnecting

electrical power and proceeding with conversion.

ELECTRICAL SHOCK, FIRE OR EXPLOSION

HAZARD

Failure to follow this warning could result in personal

iniury, death or property damage.

Before installing, modifying, or servicing system, main

electrical disconnect switch must be in the OFF position and

install a lockout tag. There may be more than one

disconnect switch. Lock out and tag switch with a suitable

warning label. Verify proper operation after servicing.

NOTE: For the 2-stage furnaces with a Series J and Series G gas

valve (see Fig. 43), they MUST have both regulator springs

replaced and the gas valve MUST be pre-adjusted.

For older model 2-stage furnaces with a Series E gas valve (see

Fig. 44), they DO NOT need to have the regulator springs

replaced in the gas valve, but the regulators in the gas valve must

be pre-adjusted for propane applications.

For J and G valves See Fig 28.

1. Be sure main gas and electrical supplies are turned OFF.

2. Remove both regulator seal caps. (See Fig. 28.)

3. Remove both regulator adjustment screws.

4. Remove both natural gas regulator springs (silver).

5. Install propane gas regulator springs (white).

6. Install regulator adjustment screws.

7. Turn low-heat stage adjusting screw clockwise (inwards)

9.5 turns, This will increase the manifold pressure closer to

the low-heat set point.

8. Turn high-heat stage adjusting screw clockwise (inwards)

13.5 turns. This will increase the manifold pressure closer

to the high-heat set point,

9. Do not install regulator seal caps at this time,

For E valves see Fig 44.

1. Be sure gas and electrical supplies to furnace are off.

2. Remove caps that conceal adjustment screws for high-

and low-heat stage gas valve regulators. (See Fig. 44.)

3. Turn low-heat stage adjusting screw (3/32-in. [2 mm] hex

Allen screw) clockwise (in) 1 full turn. This will increase

the manifold pressure closer to the propane low-heat set

point.

4. Turn high-heat stage adjusting screw (3/32-in. [2 mm]

hex Allen screw) clockwise (in) 2 full turns. This will in-

crease the manifold pressure closer to the propane high-

heat set point.

5. Do not install regulator seal caps at this time.
