! 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

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.
This instruction c overs the installation of gas conversion kit to
convert the following furnaces from natural gas usage to
propane gas usage.
NOTE: See appropriate sections for your furnace type.

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--STA GE & MODULATING
GAS VALVE
Condensing Furnaces with 40,000 through 120,000 Btuh gas
input rate and a.) Modulating gas valve with Variable--Speed
Constant Airflow ECM (VCA), b.) Two --Stage gas valve with
Variable--Speed Constant Airflow ECM (VCA), or c.) Two--Stage
gas valve with Variable--Speed Constant Torque ECM (VCT)
blower motor.
