The primary purpose of construction heaters is
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.
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.
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!
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.
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.
• Install and use heater with care. Follow all local
ordinances and codes. In the absence of local
ordinances and codes, refer to the Standard for
Storage and Handling of Liquefied Petroleum
Gas, ANSI/NFPA 58. This instructs on the safe
storage and handling of propane/LP gases.
• Use only the hose and factory preset regulator
provided with the heater.

-
drawal.

) of fresh, outside
air before using heater.
• Do not use heater in occupied dwellings, sleep
-
ing quarters, campers, tents, or any type of
