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 direct-fired, forced
air heater. It is primarily in-
tended for use for temporary
heating of buildings under
construction,alteration or repair.
Direct-fired means that all of
the combustion products of the
heater enter the heated space.
This appliance does produce
small amounts of carbon mon-
oxide. Carbon monoxide is
toxic. Humans can tolerate small
amounts of carbon monoxide,
and precautions 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.
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.
