Maintenance And Service

7.Convert the SIT gas valve:

a)Remove the black protection cap from the HI/LO knob by hand shown in Figure 7.

b)Insert a 5/32” or 4 mm Allen wrench into the hexagonal key-way of the screw (see Figure 8), rotate it counter-clockwise until it is free and extract it.

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

d)Flip the screw (refer to Figure 9).

e)Using the Allen wrench as shown in Figure 8, 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.

f)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 10). If the conversion is from LPG to NG, the red o-ring of the screw must be not visible.

8.Reinstall the burner, brick panels, log set, embers, and glass door.

Also refer to SECONDARY INSTALLATION - INSTALLING LOG SET AND EMBERS. When

re-installing the burner, ensure that the burner to pilot hood relationship

is similar to what is shown in Figure 11. On some units you will need to pay special attention when installing the burner that the venturi adjustment rod is properly installed into the venturi adjustment piece welded to the burner venturi tube

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.
