This product contains
and/or generates chemicals known to the State
of California to cause
cancer or birth defects, or
other reproductive harm.
Do not exceed 1/2 psi
(14" w.c.) gas pressure
to the gas control valve.
The heater is designed for use as
a construction heater in accordance with ANSI Z83.7/CGA
2.14. Other standards govern
the use of fuel gases and heating products for specific uses.
Your local authority can advise
you about these. The primary
purpose of construction heaters
is to provide temporary heating
of buildings under construction,
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 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! 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 may fade.
Propane gas may be present
even though no odor exists.
