Confirm that the venturi tubes are not blocked by
insects or other debris. Use a special venturi brush to
clean. (Fig. 15)
Use a wire brush or toothpick to probe the orifice in
the gas valve. Never enlarge the orifice.
Use a small nail or toothpick to clean the burner
ports.
(Fig. 16)
Corrosion of a gas burner can cause the solid mate-
rial 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 18.
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 the sear plate and drip tray are clean and
properly installed. Remove excess grease from the
burn chamber. Turn down the heat.
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 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 Igniter module to the
electrode is well seated on the termination of the
module.
A crack in the lead wire may result in shorting. Re-
place the wire.
The battery in the Igniter Button may be dead or
installed incorrectly. Correct position is positive end
down.
