Safety Considerations
WARNING: INDICATES A POTENTIALLY
HAZARDOUS SITUATION WHICH, IF NOT
AVOIDED, COULD RESULT IN DEATH OR
SERIOUS INJURY.
CAUTION: Indicates a potentially hazardous situation
which, if not avoided, may result in minor or moderate in-
jury. It may also be used to alert against unsafe practices
and where property-damage-only accidents could occur.
NOTICE
Warning and Cautions appear at appropriate
locations throughout this guide. Read these
carefully.
EXPLOSION HAZARD!
Propane gas is heavier than air and may collect in any low
areas or confined spaces. In addition, odorant fade may make
the gas undetectable except with a warning device. If the
gas furnace is installed in a basement, an excavated areas
or a confined space, it is strongly recommended to contact
a gas supplier to install a gas detecting warning device in
case of leak. The manufacturer of your furnace does not test
any detectors and makes no representations regarding any
brand or type of detector.
WARNING
!
PRECAUTIONARY MEASURES
• Avoid breathing fiberglass dust
• Use a NIOSH approved dust/mist respirator
• Avoid contact with the skin or eyes. Wear long-sleeved,
loose fitting clothing, gloves, and eye protection.
• Wash clothes separately from other clothing, rinse
washer thoroughly.
• Operations, such as sawing, blowing, tear-out, and
spraying may generate fiber concentrations requiring
additional respiratory protection. Use the appropriate
NIOSH approved respirator in these situations.
FIRST AID MEASURES
Eye Contact: Flush eyes with water to remove
dust. If symptoms persist, seek medical
attention.
Skin Contact: Wash affected area gently with soap and
warm water after handling.
This product contains fiberglass wool insulation! Fiberglass dust
and ceramic fibers are believed by the state of California to cause
cancer through inhalation. Glasswool fibers may also cause
respiratory, skin, or eye irritation.
EXPLOSION HAZARD!
To prevent an explosion or possible injury, death, and equip-
ment damage, do not store combustible materials, gasoline,

WARNING
!
IMPORTANT: This product has been designed and manufactured to meet
ENERGY STAR criteria for energy efficiency. However, proper refrigerant
charge and proper air flow are critical to achieve rated capacity and efficiency.
Installation of this product should follow the manufacturer’s refrigerant charg-
ing and air flow instructions. Failure to confirm proper charge and airflow
may reduce energy efficiency and shorten equipment life.
IMPORTANT: Do not connect gas piping to the unit until a line pressure test
has been completed. This unit should never be exposed to gas line pressure in
excess of 14 inches water column (1/2 PSIG). The furnace and its equipment
shutoff valve must be disconnected from the gas supply piping system during
any pressure testing of that system at test pressures in excess of 1/2 psi.
MPORTANT: Reconnect all grounding devices. All parts of this product capable
of conducting electrical current are grounded. If grounding wires, screws, straps,
clips, nuts, or washers used to complete a path to ground are removed for service,
they must be returned to their original position and properly fastened.
IMPORTANT: Wear appropriate gloves, arm sleeve protectors, and eye
protection when servicing or maintaining this equipment.
IMPORTANT: Air filters and media wheels or plates shall meet the test require -
ments in UL 900.
