Leak Testing Procedure
Perform a leak test at least once a year whether the
gas supply cylinder has been disconnected or not. In
addition, whenever the gas cylinder is connected to the
regulator or whenever any part of the gas system is
disconnected or replaced, perform a leak test.
As a safety precaution, remember to always leak test
your grill outdoors in a well-ventilated area. Never
smoke or permit sources of ignition in the area while
doing a leak test. Do not use a flame, such as a lighted
match to test for leaks. Use a solution of soapy water.
1.
Prepare a leak testing solution of soapy water by
mixing in a spray bottle one part liquid soap to one
part water.
2.
Make sure all the control knobs are in the OFF po-
sition.

ent.
5.
Stop a leak by tightening the loose joint or by re-
placing the faulty part with a replacement part rec-
ommended by the manufacturer. Do not attempt to
repair the cylinder valve if it is damaged. The cylin-
der must be replaced.
6.
Turn all control knobs back to the full OFF posi-
tion.
If you are unable to stop a leak:
1.
Turn all control knobs back to the full OFF posi-
tion.
2.
Shut off the gas supply to the grill and release
pressure in the hose and manifold by pushing in
and turning any of the control valves one quarter
turn counter-clockwise.
3.
On LP systems, remove the cylinder from the
grill.
4.
Call an authorized gas appliance service techni-
cian or an LP gas dealer.
Do not use the appliance until the leak is corrected.
The grill unit must be used with the gas pressure regula-
tor. The regulator will control and maintain a uniform gas
pressure in the manifold. The burner orifices have been
sized for the gas pressure delivered by the regulator.
WARNING: Attempting to operate the grill unit without
the gas regulator installed could cause an explosion and
possible death.
