TURN OFF ELECTRICAL POWER AND MAIN GAS
SUPPLy BEFORE BEGINNING MODIFICATION.
FAILURE TO DO SO CAN RESULT IN ELECTRICAL
SHOCk OR ExPLOSION CAUSING PROPERTy
DAMAGE, PERSONAL INJURy OR DEATH.
kIT INSTALLATION
1. Turn off power to unit and disconnect the gas line at the
union ahead of the combination gas valve.
2. Remove the burner compartment access door.
3. Disconnect the wires from the gas valve and remove the
screws that attach the manifold, and then remove from
assembly.
4. Follow detailed instructions on “LP Conversion Kit” to
convert the gas valve for LP (Figure is included). Con-
vert the gas valve from natural gas to LP by removing
the “NAT” sticker and applying the supplied jumper on
the receptacle located beneath the label. Make sure that
both prongs of receptacle engage
the jumper.
5. Remove the burner orifices from the manifold and re-
place with the supplied LP orifices.
6.
NOTE:
To convert the stepper-controlled modulating
gas valve, a jumper is required to connect the two pins
inside the jumper well. It is possible to install the jumper
such that the pins are not connected. This is incorrect.
The jumper must connect the pins together inside the
jumper well. This can be confirmed by visual inspection
and by verifying proper manifold pressure at high fire
(100%) after the jumper is installed. Manifold pressure
should always be checked when converting the furnace
for LP operation. Figures 33 and 34 below show the cor-
rect way and the incorrect way to install the jumper. The
jumper well is located next to the adjustment well (with
“+” and “–” text and two-headed arrow) and will be cov-
ered by a sticker or label. To convert to LP the label over
the jumper well will need to be removed.
