6. Install the airbox and the burner in their original
locations and positions and secure down using screws
you removed earlier.
7. Make certain burner is running parallel to front face
of unit and positioned properly.
Next, the pressure regulator will be changed.
8. Using a ¼" flat blade screwdriver, remove 3 screws
that secure the NG Pressure Regulator to the gas
valve body and remove NG Pressure Regulator as
shown above. Identify the pressure regulator spring
that is located in the center of the black rubber
gasket. Discard both the black rubber gasket and
spring.
9. Install the new LP Pressure Regular onto the gas valve
body in the same position and orientation as the NG
Pressure Regulator you removed in Step 2, above.
The LP Pressure Regulator can only be mounted in
one position. Secure the LP Pressure Regulator in
place using the 3 screws you removed in Step 2.
Tighten down using a ¼" flat blade screwdriver.
Burner Ignition Characteristics
Note: Connect gas supply and verify that the minimum inlet and outlet pressures are conforming.
Once the conversion to LPG and all the above steps have been completed, light the main burners.
Main burner should now light IMMEDIATELY and flame should not "lift" off burner. If there is any delay in ignition or if flame is
"lifting off" burner, turn off burner and carefully check for proper installation of logs/coals, vent system and proper pilot flame
impingement on burner. Logs or coals must not block pilot flame or main burner flame. Vent system must be leak proof.
WARNING: Do not proceed with operation of this fireplace unless burner "cycles" on/off without delays!
Pilot Flame and Burner Relationship Verification
Prior to completing the LPG conversion process, the qualified service technician must light the pilot light and verify the
relationship between the pilot light flames and the main burners. The pilot light flames directed towards the propagation ports
on the rear and front burner must overlap the propagation ports on the burners.
The pilot light flames must be a minimum of 1" long and must overlap the propagation ports on both the
rear and front burner legs. Verify that the burner tubes ignite quickly and the burner flames propagate
smoothly along the entire length of the burner.
