We cannot foresee every use which may be made of
our heaters. Check with your local fire safety au-
thority if you have questions about heater use.
Carbon Monoxide Poisoning:
more affected by carbon monoxide than others.
Early signs of carbon monoxide poisoning re-
semble 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.
Natural and Propane/LP Gas:
pane/LP gas is odorless. An odor-making agent is
added to these gases. The odor helps you detect
a gas leak. However, the odor added to the gas
can fade. Gas may be present even though no
odor exists.
Make certain you read and understand all warn-
ings. Keep this manual for reference. It is your
guide to safe and proper operation of this heater.
