The heater is designed and approved for use as a construction heater under ANSI
Z83.7. The primary purpose of construction heaters is to provide temporary heating
of buildings under construction, alteration or repair, and to provide temporary
emergency heat. 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 nausea. If you have these signs, the heater may
not be working properly. Get fresh air at once! Have heater serviced.
