Burner Ignition Characteristics
Note: Connect gas supply and verify that the minimum inlet and outlet pressures are co nforming.
Once the conversion to LPG and all the above steps have been completed, light the main burners.
Use remote transmitter to turn on pilot light and 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 burners as shown in the diagram, below. Verify that the burner tubes ignite quickly and the
burner flames propagate smoothly along the entire length of the burners.
