GAS HOOKUP & LEAK CHECK
1.
For Natural Gas: Connect a certified 1/2"
gas supply pipe to the inlet side of the
regulator from a natural gas supply, ac-
cording to local codes requirements. Use
a pipe thread sealant that is certified for
use with natural gas at connections, where
required.
2.
For L.P. Gas: Connect the regulator hose
connector to a full 20# L.P. tank, and
hand-tighten it.
3.
Turn on the gas supply to the grill.
4.
Test all of the connections by brushing on
an approved noncorrosive leak-detection
solution. Bubbles will indicate a leak. Cor-
rect any leaks found.
ADJUSTING THE AIR SHUTTERS

The Grill" on page 3-3.

and burners are cool.

Remove the burner and loosen the air
shutter adjustment screw.

the burner (too much air), turn the air
shutter clockwise.
Adjustment should be from 1/8" to 1/4".
