IMPORTANT FACTS
Your furnace must have adequate airflow for efficient combustion and safe
ventilation. Do not enclose it in an airtight room or “seal” it behind solid
doors. To minimize the possibility of
serious personal injury , fire, damage to
your furnace, or improper operation;
carefully follow these safety rules:
• Keep the area around your furnace
free of combustible materials, gasoline, and other flammable liquids and
vapors.
• Do not cover the furnace, store trash
or debris near it, or in any way block
the flow of fresh air to the unit.
• Combustion air must be clean and not
contaminated with chlorine or fluorine.
These compounds are present in many

products around the home, such as:
water softener salts, laundry bleaches,
detergents, adhesives, paints, varnishes, paint strippers, waxes, and
plastics.
Make sure the combustion air for your
furnace does not contain any of these
compounds. During remodeling be
sure the combustion air is fresh and uncontaminated. If these compounds are
burned in your furnace, the heat exchangers and metal vent system may
deteriorate.
• A furnace installed in the attic or
other insulated space must be kept free
and clear of the insulating material.
Examine the furnace area when installing the furnace or adding more insulation. Some materials may be
combustible.
NOTE:
Do not use this furnace if any
part has been under water . Immediately
call a qualified service technician to inspect the furnace and to replace any
part of the control system and any gas
control which has been under water.
