To prevent re or explosion hazard, DO NOT use or
permit sources of ignition in the area while perform-
ing a leak test. Perform leak test outdoors only. Never
perform a leak test with re or ame. DO NOT SMOKE
WHILE PERFORMING THE LEAK TEST!
To Perform Leak Test
1) Create a soapy solution of
equal parts mild dishwashing
detergent and water.
2) Conrm that all control knobs
are in the o position.
3) Turn on fuel supply. For natu-
ral gas, turn valve handle 1/4 turn
to align with gas ow. For L.P.,
turn cylinder valve knob counter
clockwise one full rotation.
4) Apply soap solution gener-
ously by paint brush or squirt
bottle on all connections and
ttings, as indicated in gures 1
and 2.
5) If “growing” bubbles appear
on any of the connection points,
then you have detected a gas
leak. IMMEDIATELY turn o the
gas supply by reversing step 3.
Fixing a Gas Leak
1) After shutting o gas sup-
ply, push in and turn on control
knobs to release pressure, then
turn the knobs back to o.
2) Wash o soapy solution with
cold water and towel dry.
3) Stop a leak by tightening
the loose joint, or by replacing
the faulty part with a replace-
ment part recommended by the
manufacturer. DO NOT attempt
to repair the L.P. cylinder valve if
it should become damaged; the
cylinder MUST BE REPLACED.
4) Perform a new leak test to en-
sure that no leaks are present.
