Dura Heat Propane Forced Air Construction Heaters
The heater is designed and approved for use as a construction heater under ANSI Z83.7., CSA2.14
It is hard to anticipate every use which may be made of this heater.
FIRE SAFETY AUTHORITY IF YOU HAVE QUESTIONS ABOUT APPLICATIONS.
Other standards govern the use of fuel gases and heat producing products in specific applications.
Your local authority can advise you about these.
IMPORTANT: Read this user's manual carefully and completely before trying to operate or
service this heater. Improper use of this heater can cause serious injury or death from fire,
explosion and carbon monoxide poisoning.
This is a direct-fired forced-air construction heater for either indoor construction or outdoor use.
Its intended use is primarily the temporary heating of buildings or structures under construction,
alteration or repair. All the products of combustion generated by the heater are forced through the
heater and released into the area being heated. This heater operates at approximately 98%+ combustion
efficiency but still produces a small amount of carbon monoxide. Humans can tolerate small
amounts of carbon monoxide for short periods. Carbon monoxide can build up in a heated space and
failure to provide adequate ventilation could result in poisoning or death.
WARNING: Not for use with ductwork.
