PROBABLE CAUSE
a. Lack of gas.
b. Obstruction in pilot orifice.
c. Defective piezo ignitor.
d. Dirty pilot electrode.
a. Lack of gas.
c. Insufficient gas pressure despite
ample gas supply.
d. Dirty or clogged orifice.
e. Venturi tube obstructed by spider webs, e. Clean out all obstructions from
wasp nest, or other foreign matter.
f. Cracked burner.
a. Low heat setting is adusted too high
(or too low).
a. Overloaded with grease drippings or
build-up, clogging ports
ventilation (too much cooking surface
covered or operation of grill on high
fire with hood closed).
c. Cracked ceramic
d. None of the above. Probable cause is
leak in packing within or under
ceramic burner head. Also can occur
through breaks in welds of burner
box. Both are manufacturer's defects
to which your warranty applies.
REMEDY
a. After turning Pilot Output Knob to ON
position, wait approximately 20-30 seconds
for air to purge gas supply line before
turning ignitor knob. Fill LP gas cylinder, if
applicable. Adjust pilot following the Pilot
Flame Adjustment procedures outlined on
Page 12.
b. Clean pilot orifice.
c. Replace piezo ignitor.
d.Clean pilot electrode.
a. Check gas level in LP gas cylinder, if
applicable.
b. Reposition regulator hose, as necessary.
c. Adjust regulator, as necessary.
d.Clean burner orifice.
venturi tube.
f. Contact Authorized Dealer. Replace ceramic
burner head.
a. Reduce (or increase) low heat setting
following procedures on Page 11.
In all cases turn burner output knob to
"OFF" position and let it cool for at least two
minutes. Then:
a. Relight burner and burn at a HIGH
setting for at least five minutes or until
ceramic glows uniformly.
b. Remove any objects or accessories which
may be covering more than 75% of the
cooking serface. Allow the burner to
cool for approximately two minutes,
then relight the burner. DO NOT
OPERATE THE GRILL ON HIGH
FIRE WITH HOOD CLOSED.
c. Allow burner to cool and inspect very
closely for cracks (which may be nearly
invisible). If cracks are found, contact dealer
to replace burner head.
d.Contact authorized dealer. Packing under
burner head should be replaced. If
backfiring continues, burner box welds
should be inspected for holes and/or burner
head should be replaced.
