<br /> A WARNING A CAUTION
<br /> 1. Do not locate ANY gas-fired unit in areas where chlorinated, Heaters are designed for use in heating applications with
<br /> halogenated, or acidic vapors are present in the atmosphere. ambient temperatures between 40°F and 80°F. Heaters
<br /> 2.Appliances must not be installed where they may be should not be used in applications where the heated space
<br /> exposed to a potentially explosive or flammable atmosphere. temperature is below 40°F. The combination of low space
<br /> and combustion air temperatures may result in condensate
<br /> freezing in the secondary heat exchanger and/or condensate
<br /> drain.
