CLEANING AND

Regularly check all burner ports for block-

of the burner. Also check the ignitor port for
blockage. This port is on the inside curve of
the burner, pointed at the ignitor electrode.
Also check the thermocouple port for block-
age. This port is on the inside curve of the
burner, pointed at the thermocouple. Clear
blocked ports by gently inserting a small
wire into the port.
Logs or lava rock may become coated with
soot. If so, clean them using a bristle brush.
Check rubber supply hose periodically for
signs of wear or damage. Check entire length
of hose, including the portion inside the
firepit pedestal. Check hose by carefully
lifting the pedestal up to view the entire
hose. If hose is damaged or worn, replace
hose before next use. Use only original
replacement parts. See Parts List on page 13
for service replacement parts.
