Maintenance And Service
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, pilot shield, glass tray, glass media, and glass door. Refer to

in your Owner’s Manual. When re-installing the burner, ensure that the
burner to pilot hood and shield relationship is similar to what is shown in Figure 23.
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 23)
.
Should the
pilot require adjustment, turn the adjustment screw (figure 36, page 33) 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.
2. Remove the glass door as shown in the

5. Convert the pilot injector (see Figure 22):
a) Using a
7

16
” wrench, loosen the pilot head counter
clockwise and fully remove
b) Remove the existing orifice and replace with the one
supplied in the kit (see Figure 22)
c) Re-install the pilot head and tighten until it is back in the
proper position (see Figure 23)
6. Convert the burner orifice:
a) Remove the main burner orifice with a
1
/
2
” deep socket
b) Replace the NG orifice with the LP orifice. Do not over-
tighten. The LP orifice hole will always be smaller then
the NG hole.
