Maintenance And Service

7.Convert the SIT gas valve:

a)Remove the extension knobs from the valve.

b)Remove the black protection cap from the HI/LO knob by hand shown in Figure 18.

c)Insert a 5/32” or 4 mm Allen wrench into the hexagonal key-way of the screw (see Figure 19), rotate it counter- clockwise until it is free and extract it.

d)Check that the screw is clean and if necessary remove dirt.

Figure 17: Fuel Conversion Tab on Pilot.

e)Flip the screw (refer to Figure 20).

f)Using the Allen wrench as shown in Figure 19, rotate the screw clockwise until a torque of 9 inch lbs. WARNING! Do not over tighten the screw. It is recommended that you grip the wrench by the short side.

g)Verify that if the conversion is from NG to LPG, the screw must be re-

assembled with the red o-ring visible (refer to Figure 21). If the conversion is from LPG to NG, the red o-ring of the screw must be not visible.

h)Re-attach the black protection cap that was removed in step a (Figure 18).

8.Re-install the burner, ceramic panels, log set and glass door. Also refer to Secondary

Installation - Log Set Installation. When

re-installing the burner, ensure that the burner to pilot hood relationship is similar to what is shown in Figure 22.

9. Reconnect the main gas line if it was

disconnected and open the shut-off valve at the gas line to the unit.

10.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.

11.Reconnect the electrical power to the unit.

12.Relight the main burner in both the “HI” and “LO” positions to verify proper burner ignition and operation and proper flame appearance (refer to Figure 43 or Front Cover). Also refer to Secondary Installation - Log Set Installation for a flame appearance picture.

13.MAKE SURE that the conversion label is installed on or close to the

rating label to signify that the unit has been converted to a different fuel type.
