IMPORTANT SAFETY INSTRUCTIONS
Potential Consequence
Serious injury or death could
occur from failure to provide
proper ventilation according to
this manual.
Prevention
This is a propane and natural
gas, direct-fired, forced air heat-
er. It is primarily intended for use
for temporary heating of build-
ings under construction,alteration
or repair. Direct-fired means that
all of the combustion products
of the heater enter the heated
space. This appliance is rated
at 98% combustion efficiency,
but does produce small amounts
of carbon monoxide. Carbon
monoxide is toxic. Humans
can tolerate small amounts of
carbon monoxide, and precau-
tions should be taken to provide
proper ventilation.
Early signs of carbon monox-
ide poisoning resemble the flu.
Symptoms of improper ventila-
tion are: * headache * dizziness
* burning of the nose and eyes *
nausea * dry mouth * sore throat.
Use this heater only in well ven-
tilated areas! Provide at least a
three square foot (2,800 sq cm)
opening of outside air for every
100,000 BTU/hr of heater rating.
People with breathing problems
should consult a physician before
using the heater.
Carbon Monoxide Poisoning:
Early signs of carbon monox-
ide poisoning resemble flu-like
symptoms such as headaches,
dizziness, and/or nausea. If you
have these symptoms, your heat-
er may not be working properly.
Get fresh air at once! Have the
heater serviced. Some people are
more affected by carbon mon-
oxide than others. These include
pregnant women, those with
heart or lung problems,anemia,
or those under the influence of
alcohol, or at high altitudes.
Never use this heater in living or
sleeping areas.
