TO AVOID PROPERTY DAMAGE, PERSONAL INJURY OR DEATH, SUFFICIENT
FRESH AIR MUST BE SUPPLIED FOR PROPER COMBUSTION AND VENTILATION
OF FLUE GASES.
Since the gas/electric unit is installed completely in the outdoors, the
depletion of combustion air is highly improbable. To ensure an adequate
supply of combustion air, do not allow the air inlet louvers in the
condenser coil section or the flue hood outlet to become blocked by
leaves, snow, rubbish, or insect (wasps) nests. Never block the con-
densing unit section in the winter with covers. Blocking of this section
would prevent an adequate amount of combustion air from reaching the
furnace section.
Great care has been taken in the design and manufacture of your unit to
provide for your comfort and safety. Be aware of the possibility that some
problems with your unit or other gas-fired appliances could cause flue
gases to be present in your building. These flue gases could include
carbon monoxide.
CARBON MONOXIDE POISONING HAZARD
Special Warning for Installation of Furnace or Air Handling Units in
Enclosed Areas such as Garages, Utility Rooms or Parking Areas
Carbon monoxide producing devices (such as an automobile, space
heater, gas water heater, etc.) should not be operated in enclosed areas
such as unvenlilated garages, utility rooms or parking areas because of
the danger of carbon monoxide (CO) poisoning resulting from the exhaust
emissions. If a furnace or air handler Is Installed In an enclosed area such
as a garage, utility room or parking area and a carbon monoxide producing
device is operated therein, there must be adequate, direct outside
ventilation.
This ventilation is necessary to avoid the danger of CO poisoning which
can occur if a carbon monoxide producing device continues to operate In
the enclosed area. Carbon monoxide emissions can be (re)circulated
throughout the structure if the furnace or air handler is operating In any
mode.
CO can cause serious illness including permanent brain damage or death
PERSONAL INJURY OR DEATH FROM ASPHYXIATION CAN RESULT FROM
EXPOSURE TO CARBON MONOXIDE. CARBON MONOXIDE OR " C O " IS A
COLORLESS AND ODORLESS GAS PRODUCED WHEN FUEL IS NOT BURNED
COMPLETELYOR WHEN THE FLAME DOES NOT RECEIVE SUFFICIENT OXYGEN.
BE AWARE OF THESE AIR STARVATION SIGNALS WHICH INDICATE CONDITIONS
THAT MAY RESULT IN CARBON MONOXIDE OR THAT CARBON MONOXIDE MAY
BE PRESENT:
1. HEADACHES-NAUSEA-DIZZINESS, FLU-LIKE SYMPTOMS.
2. EXCESSIVE HUMIDITY-HEAVILY FROSTED WINDOWS OR A MOIST "CLAMMY"
FEELING IN THE HOME.
3. SMOKE FROM A FIREPLACE WILL NOT DRAW UP THE CHIMNEY.
4. FLUE GASES THAT WILL NOT DRAW UP THE APPLIANCE VENT PIPE.
TO PREVENT PROPERTY DAMAGE OR SERIOUS PERSONAL INJURY DUE TO
FIRE OR EXPLOSION CAUSED BY A PROPANE GAS LEAK, INSTALL A GAS
DETECTING WARNING DEVICE.
IF THE PROPANE GAS UNIT IS INSTALLED IN AN EXCAVATED AREA OR A
CONFINED SPACE, A WARNING DEVICE IS REQUIRED DUE TO:
• PROPANE GAS IS HEAVIER THAN AIR AND ANY LEAKING GAS CAN
SETTLE IN ANY LOW AREAS OR CONFINED SPACES.
• PROPANE GAS ODORANT MAY FADE, MAKING THE GAS UNDETECTABLE
EXCEPT WITH A WARNING DEVICE.
AN UNDETECTED GAS LEAK WILL CREATE A DANGER OF EXPLOSION
OR FIRE. IF THE PRESENCE OF GAS IS SUSPECTED, FOLLOW THE
INSTRUCTIONS ON THE COVER OF THIS MANUAL. FAILURE TO DO SO
COULD RESULT IN S E R I O U S P E R S O N A L I N J U R Y OR D E A T H .
THERMOSTAT
This unit will not operate properly without a good quality, correctly
installed thermostat. It is very important that the thermostat be
located where it can best "sense" the average room temperature.
Be sure the thermostat is not exposed to hot or cold drafts or to hot
or cold spots on the wall, such as those received from outside
walls, walls with pipes inside, or from openings into the attic.
No matter the type or style, thermostat operation is basically the
same. The most widely used types will control both heating and
cooling functions and will have a Fan Switch with Auto and ON
settings. On Auto, the Circulating Air Blower will cycle on/off, but
if switched to ON it will run constantly.
B10259-216
IMPORTANT NOTE: To avoid the possibility of damage to the unit
heat exchanger, do not set the thermostat fan switch to ON
(constant fan operation) during the heating season without first
consulting the installer of the unit or another qualified servicer.
There are thermostats that automatically switch from Heating to
Cooling, or with night setbacks. The night setback, or multiple
setback type, will lower the temperature at night or during the day
when the building is unoccupied.
