SAFETY INFORMATION
DANGER
• CARBON MONOXIDE HAZARD
• This heater is a combustion appliance. All
combustion appliances produce carbon monoxide
(CO) during the combustion process. This product is
designed to produce extremely minute, non-hazardous
amounts of CO if used and maintained in accordance
with all warnings and instructions. Do not block air
flow into or out of the heater.
• Carbon Monoxide (CO) poisoning produces flu-like
symptoms, watery eyes, headaches, dizziness, fatigue
and possibly death. You can't see it and you can't
smell it. It's an invisible killer. If these symptoms are
present during operation of this product get fresh air
immediately!
• For outdoor use only.
• Never use inside house, or other unventilated or
enclosed areas.
• This heater consumes air (oxygen). Do not use in
unventilated or enclosed areas to avoid endangering
your life.

this product contain chemicals known to the State
of California to cause cancer, birth defects, and
other reproductive harm.
WARNING
BURN HAZARD
• Never leave heater unattended when hot or in use.
• Keep out of reach of children.
WARNING
• This product is fueled by propane gas. Propane gas
is invisible, odorless, and flammable. An odorant is
normally added to help detect leaks and can be
described as a “rotten egg” smell. The odorant can
fade over time so leaking gas is not always detectable
by smell alone.
• Propane gas is heavier than air and leaking propane
will sink to the lowest level possible. It can ignite by
ignition sources including matches, lighters, sparks or
open flames of any kind many feet away from the
original leak. Use only propane gas set up for vapor
withdrawal.
• Store or use propane gas in compliance with local
ordinances and codes or with ANS/NFPA 58. Turn off
propane when not in use.
WARNING
• Alert children and adults to the hazards of high surface
temperatures. Stay away from these surfaces to avoid
burning skin or igniting clothing.
• Carefully supervise young children when in the vicinity
of the heater.
• Do not hang clothing or any other flammable materials
from the heater, or place on or near the heater.
• Replace any guard or protective device removed for
servicing the appliance prior to placing back in service.
• Installation and repair should be done by a qualified
service person. The heater should be inspected
before use and annually by a qualified service person.
More frequent cleaning may be required as necessary.
It is imperative that the control compartment, burners,
and circulating air passageway of the appliance be
