INFORMATION
IMPORTANT: Read this owner’s
manual carefully and completely
before trying to assemble, oper-
ate, or service this heater. Im-
proper use of this heater can
cause serious injury or death from
burns, fire, explosion, electrical
shock, and carbon monoxide
poisoning.
Carbon Monoxide Poisoning: Early signs of
carbon monoxide poisoning resemble the flu,
with headaches, dizziness, or nausea. If you
have these signs, the heater may not be work-
ing properly. Get fresh air at once! Have
heater serviced. Some people are more af-
fected by carbon monoxide than others. These

Natural Gas: Natural gas is odorless. An
odor-making agent is added to the gas. The

the odor added to the gas can fade. Gas may
be present even though no odor exists.
