SAFETY INSTRUCTIONS
GENERAL SAFETY
INSTRUCTIONS
• Due to high temperatures, the
appliance should be located out of
traffic and away from combustible
materials.
• Children and adults should be
alerted to the hazard of high surface
temperatures and should stay away to
avoid burns or clothing ignition.
• Do not leave this cooker unattended
while it is in operation. Keep children
and pets away from the cooker at all
time.
• Do not place clothing or other
flammable material on or near the
appliance.
• If cooking grate is removed for
servicing the appliance, it must be
replaced prior to operating the cooker.
• The appliance should be inspected
before each use. Clean cooker
frequently to avoid grease
accumulation and possible grease fires.
The control compartments, burner
and circulating air passageways of
the appliance must be kept clean, see
MAINTENANCE.
• DO NOT use this cooker if any part
has been under water. Immediately
call a qualified service technician to
inspect the cooker and to replace any
part of the control system and any gas
control, which has been under water.
• When used without adequate
combustion and ventilation air, this
cooker may give off excessive CARBON
MONOXIDE, an odorless, poisonous
gas.
WARNING: Early signs of carbon
monoxide poisoning resemble the
flu, with headache, dizziness, and/or
nausea. If you have these signs, the
cooker may not be working properly.
Get fresh air at once! Have cooker
serviced.
Some people - pregnant women,
persons with heart or lung disease,
anemia, those under the influence of
alcohol, those at high altitudes - are
more affected by carbon monoxide
than others.
• When cooker is placed on the ground,
make sure the ground is level and
keep any objects at least 8 inches from
the front of the cooker.
ODOR FADING ‑ NO ODOR
DETECTED
• Some people cannot smell well. Some
people cannot smell the odor of the
man-made chemical added to propane
(LP) gas. You must determine if you
can smell the odorant in these fuel
gases.
• Learn to recognize the odor of
propane (LP) gas. Local propane (LP)
gas dealers will be more than happy to
give you a scratch and sniff pamphlet.
Use it to become familiar with the fuel
gas odor.
• Smoking can decrease your ability
to smell. Being around an odor for
a period of time can affect your
sensitivity to that particular odor.
Odors present in animal confinement
buildings can mask fuel gas odor.
• The odorant in propane (LP) gas
is colorless and the intensity of
its odor can fade under some
circumstances.
• If there is an underground leak, the
movement of gas through the soil can
filter the odorant.
• Propane (LP) gas odor may differ
in intensity at different levels. Since
propane (LP) gas is heavier than air,
there may be more odor at lower
levels.
• Always be sensitive to the slightest
gas odor. If you continue to detect
any gas odor, no matter how small,
treat it as a serious leak. Immediately
go into action as discussed previously.

• Even If you are not property trained in
the service and repair of the cooker,
ALWAYS be consciously aware of the

• If you have not been properly trained
in repair and service of propane (LP)

cooker, perform service or repairs, or
make any adjustments to the cooker
on the propane (LP) gas fuel system.
• A periodic sniff test around the cooker

CONTACT YOUR FUEL GAS SUPPLIER
IMMEDIATELY. DO NOT WAIT!
