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 enter the heated
space. Even though this heater operates very close
to 100 percent combustion efficiency, it still pro-
duces 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.
