The heater is designed for use as a construc- tion heater in accordance with ANSI Z83.7/ CGA 2.14. Other standards govern the use of fuel gases and heating products for spe- cific uses. Your local authority can advise you about these. The primary purpose of construction heaters is to provide temporary heating of buildings under construction, al- teration 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 monox- ide than others. Early signs of carbon mon- oxide poisoning resemble the flu, with head- aches, dizziness, and/or nausea. 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.

Natural Gas: Natural gas has a distinctive odor. This odor helps you detect a natural gas leak. However, the odor may fade. Natu- ral gas may be present even though no odor exists.
