to provide temporary heating of buildings under
construction, alteration or repair. Properly used,
the heater provides safe economical heating.
Products of combustion are vented into the area
being heated.

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: Some people are
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.
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 may fade. Propane 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.

handling of propane gases.
