WARNINGS
The heater is designed for use as a construc-
tion heater. Certain standards govern the
use of fuel gases and heating products for
specific uses. Your local authority can ad-
vise you about these. The primary purpose
of construction heaters is to provide tempo-
rary 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.
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.
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.
