ACTION REQUIRED
Confirm that the venturi tubes are not blocked by
insects or other debris. Use a special venturi brush
to clean (Fig. 15).
Use a pin or needle to probe the orifice in the gas
valve. Never enlarge the orifice (Fig. 16).
Use a small nail or toothpick to clean the burner
ports (Fig. 16).
Corrosion of a gas burner can cause the solid
material between the gas ports to deteriorate,
resulting in uneven burning. See your retailer for
the appropriate replacement burner.
Your Grill should burn with a predominantly blue
flame. If the flame is mostly yellow, check the
venturi tubes for obstruction and clean as shown
on Page 19. If yellow flames still persist, adjust the
opening on the air shutter of the venturi tube
located under the front console of the Grill (Fig.
20).
Trim all excess fat from meat before cooking.
Confirm that the sear plate is clean and properly
installed. Remove excess grease from the burn
chamber.
Wipe the electrode with a soft, clean cloth.
The electrode should be located 1/8” to 3/16”
from the burner, and positioned to spark to the
edge of a gas port. If the gap is incorrect, or the
unit is not properly sparking, gently bend the
electrode tip into position. Use caution so that the
ceramic insulator does not crack.
If the ceramic insulator on the electrode is cracked,
it may short out. Replace the electrode.
Confirm that the lead from the Ignitor module to
the electrode is well seated on the termination of
the module.
A crack in the lead wire may result in shorting.
Replace the wire.
The battery in the Igniter Button may be dead or
installed incorrectly. Correct position is positive
end down.
