LEAK TESTING
GENERAL
Although gas connections on the grill are leak
tested prior to shipment, a complete gas tightness
check must be performed at the installation site.
Periodically check the whole system for leaks
following the procedures listed below.
If the smell of gas is detected at anytime, you
should immediately check the entire system for
leaks.
BEFORE TESTING
Make sure all packing materials have been
removed from the grill, including the burner tie-
down straps.
WARNING
Check all gas supply fittings for leaks before each
use
.
Do not use the grill until all connections have
been checked and do not leak.
Do not smoke while leak testing.
Never leak test with an open flame.
Make a soap solution of one part liquid detergent
and one part water. You will need a spray bottle,
brush, or rag to apply the solution to the fittings.
TO TEST
1. Make sure the control valves are in the “OFF”
position, and turn on the gas supply.
2. Check all connections from the natural gas
regulator and supply valve up to and including
the connection to the manifold pipe assembly
(the pipe that goes to the burners). Soap
bubbles will appear where a leak is present.
3. If a leak is present, immediately turn off the gas
supply and tighten leaky fittings.
4. Turn the gas back on and recheck.
5. Should the gas continue to leak from any of the
fittings, turn off the gas supply and contact
customer service at 1-800-554-5799.
Only those parts recommended by the
manufacturer should be used on the grill.
Substitutions will void the warranty.
GAS FLOW CHECK
Each grill burner is tested and adjusted at the
factory prior to shipment. However, variations in the
local gas supply may make it necessary to adjust
the burners.
Flames should be blue and stable with no yellow
tips, excessive noise or lifting.
If any of these conditions exist, first check to see if
the burner is blocked by dirt, debris, spider webs,
etc.
If the burner is free of blockages, you will need to
fine-tune the air/gas mixture by moving the
adjustment bolt (See the image on page 9).
Remember it is better to make several minor
adjustments as opposed to a single large
adjustment.
It is handy to keep a spray bottle of soapy water
near the shut-off valve of the gas supply line. Spray
all the fittings. Bubbles indicate leaks.
