PROBLEM

POTENTIAL CAUSE

 

ACTION REQUIRED

 

 

 

 

Uneven burn pattern

Blockage in the burner or gas

Confirm that the venturi tubes are not blocked by insects or

or

system

other debris. Use a special venturi brush to clean (Fig. 15).

Flashback fire

 

Use a pin or needle to probe the orifice in the gas valve.

 

 

 

 

Never enlarge the orifice (Fig. 17).

 

 

Use a small nail or toothpick to clean the burner ports

 

 

(Fig. 17).

 

Corroded burner

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.

 

 

 

 

Excessive yellow

Improper air shutter opening

Your Grill should burn with a predominantly blue flame.

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).

 

 

 

 

Flare-up

Excessively fatty foods

Trim all excess fat from meat before cooking.

 

Grease buildup

Confirm that the sear plate is clean and properly installed.

 

 

Remove excess grease from the burn chamber.

 

 

 

 

Igniter does not spark

Electrode fouled

Wipe the electrode with a soft, clean cloth.

 

Electrode improperly gapped

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.

 

Electrode cracked

If the ceramic insulator on the electrode is cracked, it

 

 

may short out. Replace the electrode.

 

Lead wire is disconnected

Confirm that the lead from the Ignitor module to the

 

 

electrode is well seated on the termination of the

 

 

module.

 

Lead wire is cracked

A crack in the lead wire may result in shorting. Replace

 

 

the wire.

 

Battery dead or installed wrong

The battery in the Igniter Button may be dead or installed

 

 

incorrectly. Correct position is positive end down.
