Maintenance
DANGER
To prevent risk of electrical shock, disconnect power cord
before attempting to clean any part of the unit.
Notice
We DO NOT recommend covering components with
aluminum foil. Instead, we recommend following the
Daily Cleaning Summary to keep the grill clean. However,
if aluminum foil is used, it is imperative that the foil DOES
NOT block the air holes in the ceramics under the cook
grates.
Notice
Never cover the cook surface (eg: with sheet pans) as a
method of cleaning the unit. The heat generated by doing
so can damage the electronics in the unit. As a result,
the unit is equipped with a temperature sensor that will
detect this condition and shut the unit down before any
components/electronics can be damaged by heat.
Please read this section carefully prior to undertaking any
cleaning or maintenance on the unit.
To maintain maximum efficiency of the grill, it is necessary
to keep it clean. Grill use and type of product will actually
determine the frequency of cleaning.
Cleaning the Flame Sense/Igniter Probe
• If you notice that the burner has started shutting off
during operation, and that it has gotten worse over time;
the flame sense probe (also igniter probe) needs to be
cleaned.
• This unit relies on flame rectification to determine
whether or not the burner is lit. The ignition module
inside the unit monitors the flame rectification circuit
for safety. When the burner is on, AC current is rectified
by the flame causing a small DC microamp current to
flow back to the ignition module so it knows a flame
is present. If the flame sense probe is dirty, the flame
rectification circuit is broken (even if a flame is present)
and the ignition module will shut off the flow of gas for
safety. If this happens 3 times in a row, the burner will
“lock out” and the unit will need to be powered off and
on before the unit will attempt to light the burner again.
To prevent this problem, the flame sense probe needs to
be kept clean.
• During normal operation and cooking with this unit, the
flame sense probe can become contaminated with salts,
fats and oils; therefore we recommend cleaning it daily as
follows:
Cleaning Under Grates
Notice
Ensure the unit has cooled before removing parts and
cleaning ceramics.
Notice
Quenching hot grates in cold water may cause them to
crack or bow.
Notice
Pouring cold water on hot ceramics may cause the
ceramics to crack.
• At the end of the day, the cook grates should be cleaned
in place using the brush and scraper that were provided
with the unit.
• Then remove the grates from the unit and wash them
in the sink. The cast iron caps can also be removed and
washed in the sink.
• Remove the ceramic ring(s) and vacuum underneath. Be
careful not to hit the flame sense/igniter probe or bend it
out of place.
• Clean the flame sense/igniter probe by using a piece
of abrasive strip to remove the salts and oils from the
portion of the flame sense rod - as per picture below.
Notice
The flame sense rod is somewhat delicate. Do not use a lot
of force when cleaning the flame sense rod and take care
not to bend it out of place.
• Wipe off the flame sense rod (including white ceramic
portion) with a DRY cloth..
