WARNINGS

SAFETY
INFORMATION

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 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 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.

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 can fade. Propane gas may be present
even though no odor exists.

Make certain you read and understand all
Warnings. Keep this manual for reference.

of this heater.
