The heater is designed and approved for use as a construction heater
under ANSI Z83.7•CGA Z.14-2000 Construction Heater. The pur-
pose 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 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: Some people are more affected by
carbon monoxide than others. Early signs of carbon monoxide
poisoning resemble the flu, with headaches, dizziness, and/or nau-
sea. If you have these signs, the heater may not be working properly.
Get fresh air at once! Have heater serviced.
Propane/LP Gas: Propane/LP gas is odorless. An odor-making agent
is added to propane/LP gas. The odor helps you detect a propane/LP
gas leak. However, the odor added to propane/LP gas can fade.
Propane/LP gas may be present even though no odor exists.
Make certain you read and understand all warnings. 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 Petro-
leum Gas, ANSI/NFPA 58 and the Propane Installation Code,
CAN/CGA B149.2. This instructs on the safe storage and han-
dling of propane gases.
WARNING: NOT FOR HOME OR RECREATIONAL
VEHICLE USE.
