Problem Possible Causes Solution
Infrared burner (if equipped)
flashes back (during operation
the burner abruptly makes a
loud “whoosh” sound, followed
by a continuous blow-torch type
sound and grows dim.) Ceramic tiles overloaded with
grease drippings and build-up.
Ports are clogged.
Burner overheated due to
inadequate ventilation (too much
grill surface covered by griddle
or pan.)
Cracked ceramic tile.
Leaking gasket surrounding the
ceramic tile, or a weld failure in
the burner housing.
Turn burner off and allow to cool for at least two minutes.
Relight burner and burn on high for at least five minutes or
until the ceramic tiles are evenly glowing red.
Ensure that no more than 75% of the grill surface is covered by
objects or accessories. Turn burner off and allow to cool for at
least two minutes, then relight.
Allow burner to cool and inspect very closely for cracks. If any
cracks are found, contact your authorized Ultra Chef dealer to
order a replacement burner assembly.
Contact your authorized Ultra Chef dealer for instructions on
ordering a replacement burner assembly.
Pilot will not light.
(if equipped) Lack of gas.
Obstruction in pilot orifice.
Electrode wire loose or off.
Dirty pilot electrode.
Pilot is actually lit.
After turning pilot knob to high, wait approximately 20-30
seconds for air to purge the gas supply line while pressing
igniter. Fill propane cylinder. During initial set-up or after tank
has been refilled, it is best to light one of the tube burners
before lighting the pilot burner. This enables the gas to reach
the valves on the manifold more quickly.
Clean pilot orifice.
Replace lead wire.
Clean pilot electrode.
The pilot flame, especially on natural gas units is very difficult
to see. Place your hand 1 in. (2.5 cm) above grill surface over
the pilot burner to feel for heat.
