This instruction covers the installation of gas conversion kit to convert
the following furnaces from propane gas usage to natural gas usage.
NOTE: See appropriate sections for your furnace type.
Table 1 – Kit Contents
SINGLE-STAGE GAS VALVE
Condensing Furnaces with 40,000 to 140,000 BTUH (not all models
have 140,000 BTUH) gas input rates and a.) Single-Stage, 4-Way
Multipoise, Hot Surface Ignition with PSC blower motor or b.)
Single-Stage gas valve with Fixed-Speeds Constant Torque ECM (FCT)
blower motor.
TWO-STAGE & MODULATING GAS VALVE
Condensing Furnaces with 40,000 through 120,000 BTUH gas input rate

Constant Torque ECM (VCT) blower motor.
DESCRIPTION AND USAGE
This kit is designed for use in the furnaces listed in Table 2 or Table 3 ,
see Table 1 for kit contents. To accommodate many different furnace
models, more parts are shipped in kit than will be needed to complete
conversion. When installation is complete, discard extra parts.

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.
CAUTION
!
UNIT OPERATION HAZARD
Failure to follow this caution may result in unit damage or improper
operation.
Do NOT use this kit with furnaces with an input of 26,000 BTUH; the
unit will be severely over-fired. This could result in delayed ignition,
sooting or premature heat exchanger failure.
