7. Convert the SIT gas valve:
a) Use a T-20 driver to remove the two screws that hold the stepper regulator to the gas valve and
disconnect the wire harness from the IFC.
b) Remove the rubber regulator diaphragm that is situated between the stepper regulator and the
valve body. The new stepper regulator already has this diaphragm installed.
c) Install the LP stepper regulator, with the new longer T-20 screws included in the kit and connect
the harness to the IFC.
8. Reinstall the burner, fire grate, log set, and glass door.

9. Reconnect the main gas line if it was disconnected and open the shut-off valve at the gas line to
the unit.
10. Reconnect the electrical power to the unit.
11. Use a small brush to apply a warm soapy water solution to all gas connections (use a half dish
soap and half warm water). If a gas leak is present, bubbling will occur. Gas leaks can be repaired
by using an approved pipe thread sealant or approved Teflon tape. NEVER USE AN OPEN FLAME
WHEN TESTING FOR LEAKS.
12.
Relight the pilot and confirm the flame properly covers the flame sensor (see Figure 22)
.
Should the
pilot require adjustment, turn the adjustment screw clockwise to decrease or counterclockwise to
increase until the correct flame is achieved.
Conversion Kit Installation:
1. Turn the unit off by pressing the ON/OFF Key on the remote and shut off gas supply at the shut-off
valve upstream of the unit. CAUTION: The gas supply must be shut off prior to disconnecting the
electrical power and before proceeding with the conversion. Allow the valve and unit to cool down
to room temperature.
