Converting the stove between natural gas (NG) and propane
(LP) can be accomplished by either changing the cassette
(valve and pilot assembly) or installing a conversion kit
(regulator, burner orifice, and repositioning the slide ori-
fice of the pilot). Only a qualified service technician should
perform the conversion.

Caution: Label all wires prior to disconnection when
servicing controls. Wiring errors can cause improper
and dangerous operation. Verify proper operation after
servicing.
1. Be sure the gas supply is shut off. The electrical supply
for the blower should be shut off at the electrical panel
before beginning the conversion. Disconnect the gas sup-
ply from the stove, being careful not to apply pressure to
the valve in the process.
2. Remove the log set (see “Log Installation”).
3. Remove the two phillips head screws from the back of
the burner.
4. Lift the right end of the burner and slide if off the orifice
and shutter tube. Remove the burner from the firebox.
5. Remove the labeled cover through which the valve control
knobs protrude by removing the two screws securing it
and slide it off the valve knobs.
6. Mark and disconnect wires on valve terminals #1 and
#3 connected to the burner on/off switch, thermostat,
or remote control. Disconnect the igniter wire from the
control panel.
7. From inside the firebox, remove the two allen head screws
that fasten the log support in and remove the log support
piece.
8. From inside the firebox, remove all three of the allen head
screws (see Figures 29 & 30) fastening the cassette to
the firebox.
9. Grasp the cassette assembly from below the firebox and
lower the front edge away from the firebox.
10. Install the new, converted, or serviced cassette in the
reverse order of removal. All surfaces of the cassette
must be sealed to the firebox to ensure an air tight seal.
Replace damaged gasket.
11. All parts and wires must be correctly reinstalled to ensure
safe and proper operation of the unit.
