WARNING: BURN, FIRE, EXPLOSION, AND/
OR CARBON MONOXIDE HAZARD. Failure to
obey the following warnings could result in
death or serious injury:
• Shut off and disconnect all gas sources before
performing service or maintenance on this appliance.
• Dometic gas-operated cooking units are for use with
liquid propane (LP) gas only in recreational vehicles
only, such as travel trailers, motor homes, and tent
campers.
• Never use the range or slide-in as a space heater to
heat or warm the room or as a storage space.
• Do not store or use gasoline or other flammable
vapors and liquids in the vicinity of this or any other
appliance.
• Shut off all gas appliances and pilot lights when
refueling gasoline or LP tanks, or when the vehicle is
in motion.
• Verify that there is a sufficient gas supply before
attempting to light any burner. Air in the line will
significantly delay the burner ignition and a burner
may light unexpectedly as the air in the line clears out
and is replaced by LP gas.

WARNING: CARBON MONOXIDE HAZARD.
This product can produce carbon monoxide, which
has no odor and can be life-threatening. Gas flames
consume oxygen, which must be replaced to
assure proper combustion. Provide fresh air during
testing, service, and maintenance of this appliance.
Failure to obey this warning could result in death or
serious injury.

WARNING: HIGH TEMPERATURE HAZARD.
Failure to obey the following warnings could
result in death or serious injury:
• Do not touch burners, burner grates, or areas near
burners during and/or immediately after use as they
will be hot. Do not let clothing or other flammable
materials contact burners or areas near burners until
these areas have had sufficient time to cool.
• Supervise young children in the same room as the
range.
