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.
