WARNING

ELECTRICAL SHOCK, FIRE OR EXPLOSION

HAZARD

Failure to follow this warning could result in personal

injury, 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.

!

WARNING

NOTE

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

valve (see Fig. 41),

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. 42), 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 natural applications.

For J and G valves See Fig 41.

1. Be sure main gas and electrical supplies are turned OFF.
2. Remove both regulator seal caps. (See Fig. 41.)
3. Remove both regulator adjustment screws.
4. Remove both Propane gas regulator springs (white).
5. Install natural gas regulator springs (silver).
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)

12 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 42.

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. 42.)

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

Allen screw) counter clockwise (outwards) 1 full turn.
This will decrease the manifold pressure closer to the nat-
ural low--heat set point.

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

hex Allen screw) counter clockwise (outwards) 2 full

turns. This will decrease the manifold pressure closer to
the natural high--heat set point.

5. DO NOT install regulator seal caps at this time.
