shut-off.

To prevent damage to connections, piping, and
components, always use two wrenches to loosen the

NOTE
The burner slots may be cleaned with a small flat
file. The inner bore of the burner body may be cleaned
with a 3/16 in., double-spiral wire brush. Do not
damage the threads when cleaning the inner bore of
the burner.
NOTE
Do not insert any type of cleaning tool or wire into the
orifice. Do not drill or ream the orifice opening to clean
it. Insertion of any type of cleaning tools, reaming, or
drills through the opening will alter the volume of LP
gas flow to the burner and create a fire hazard potential.
