We cannot foresee every use which may be
made of our heaters. Check with your local
fire safety authority if you have questions
about heater use.
Other standards govern the use of fuel gases
and heat producing products for specific
uses. Your local authorities can advise you
about these.
Carbon Monoxide Poisoning: Direct-Fired
means that all of the combustion products en-
ter the heated space. Even though this heater
operates very close to 100 percent combus-
tion efficiency, it still produces small amounts
of carbon monoxide. Some people are more
affected by carbon monoxide than others.
Early signs of carbon monoxide poisoning
resemble the flu, with headaches, dizziness,
and/or nausea. If you have these signs, the
heater may not be working properly. Get fresh
air at once! Check for proper ventilation and
have heater serviced.
Propane Gas: Propane gas is odorless. An
odor-making agent is added to propane gas.
The odor helps you detect a propane gas
leak. However, the odor added to propane
gas can fade. Propane gas may be present
even though no odor exists.
