WARNING
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.
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.

WARNING
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.

IMPORTANT: 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 charging
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 pres-
sure 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.
IMPORTANT: 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.
