INSTALLATION OF LAVA ROCK/MEDIA INTO BURNER PAN
Install lava rock into the burner pan. Ensure the lava rock is a
1-inch diameter for proper operation.
Note:
Do not pour Lava
Rock directly from bag. It should be placed naturally and NOT
packed in tight. Loose fitting is important to ensure robust flames.
Be sure rocks are free of any excessive dust. This prevents the
burner pan weep holes from being plugged and holding water.
IMPORTANT
:
Do not place rock over top or under the screen
cover.
The screen must be free of any debris to ensure proper
lighting of burner and good flame sense (See Fig. 17).
Cover the burner completely with media but do not make the depth
greater than 1-inch overtop of the burner portholes.
Do NOT cover the screen mesh with any rock or glass. It must be
free an any debris to operate properly.
IGNITOR ALIGNMENT
It is important check that the ignitor probes be properly aligned over-
top of the burner port holes and did not move during shipping. Use
the Fig.16 as a guide. Before lighting remove the screen cover of the
ignition hood to burner and ensure the thermocouple is directly over-
top of a burner port hole. The sparking probes and the thermocouple
must be in the path of a flame to ignite the gas for proper ignition of
the flame. Replace the screen cover and follow the operating
instructions.
