The heater is designed for use as a construction heat-
er 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 au
-
thority 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 re
-
semble 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.
Natural and Propane/LP Gas: Natural and pro-
pane/LP gas is odorless. An odor-making agent is
added to these gases. The odor helps you detect
a gas leak. However, the odor added to the gas
can fade. Gas may be present even though no
odor exists.
