REINSTALLING THE MAIN BURNER
Reinstall the hearth pan by sliding the end flange over the bottom edge of the refractory stand then center and slide the front edge
down between the raised hearth support.
Reinsert the two side bricks in reverse order then center the view port in the hearth pan over the orifice mount.
Visually check the air shutter setting on the main burner. The air shutter should be fully opened for use with Propane/LP gas. If not
fully opened, back off on the adjustment screw and turn the air shutter until the openings are fully exposed, then retighten the
adjustment screw.
Insert the main burner venturi tube through the center cutout in the hearth pan and slide the air shutter mount over the orifice (see
figure 37). Replace the two mounting screws
GAS CONTROL VALVE CONVERSION
Convert the gas control valve by swapping out the valve regulator portion of the gas valve.
Using a TORX T20 or a slotted screwdriver, remove and discard the three mounting screws, pressure regulator tower, and
diaphragm/spring components (see figure 36).
The rubber gasket is part of the pressure regulator assembly, make sure it is properly positioned. Install the new pressure regulator
assembly to the valve using the new mounting screws supplied with the kit. Tighten the screws securely (approximately 25in-lbs.)
(see figure 38).
Install the identification label enclosed with the gas valve regulator to the valve body where it can easily be seen (see figure 38).
