Leak Testing; Venturi Tubes - OMC GAS BARBECUES Owner's Manual

LEAK TESTING

All factory-made connections have been thoroughly tested
for gas leaks. However, shipping and handling may have
loosened a gas fitting.
AS A SAFETY PRECAUTION:
•
Test all fittings for leaks before using your gas
barbecue.
•
Test the cylinder valve for leaks each time the
cylinder is filled.
•
Test for leaks every time you connect a gas fitting.
•
Do not smoke!
•
Never test for leaks with a lighted match or open
flame.
•
Test for leaks outdoors.
TO TEST FOR LEAKS:
1. Extinguish any open flame or
cigarettes in the area.
2. Be sure that cylinder valve and
appliance valves are "off".
3. Connect LP gas cylinder. See
"Hose and Regulator".
4. Prepare a soap solution of one
part water, one part liquid
detergent.
5. With a full gas cylinder, open cylinder slowly.
6. Brush the soap solution on each connection.
If your barbecue is equipped with a side burner or rear
burner:
a. Place finger tip over the opening in the orifice at the end
of hose.
b. Turn "SIDE"/"REAR" control to "HI".
c. Brush soap solution on each connection between orifice
and control valve.
d. Turn "SIDE"/"REAR" control to "OFF".
7. A leak is identified by a flow of bubbles from the area
of the leak.
8. If a leak is detected, close the gas cylinder "shut-off"
valve, tighten the connection and retest (Step 5).
9. If the leak persists, contact your barbecue dealer for
assistance. Do not attempt to operate appliance if a
leak is present.

VENTURI TUBES

•
Keep venturi tubes clean.
•
Blockages caused by spiders insects and nests can
cause a flashback fire.
Although the barbecue might still light, the backed up gas
might also ignite and cause a fire around the venturi tubes at
the control panel or side burner.
