The heater is designed for use as a construction heater in accordance
with ANSI Z83.7/CGA 2.14. Other standards govern the use of fuel
gases and heating products for specific uses. Your local authority
can advise you about these. The primary purpose of construction
heaters is to provide temporary heating of buildings under construc-
tion, 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! 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 warnings. Keep this
manual for reference. It is your guide to safe and proper operation
of this heater.
