UNIT INSTALLATION
Examine the unit installation to determine the following:
The flue hood connector is in place and is physically sound
without holes or excessive corrosion.
The mounting pad support of the unit is sound.
There are no obvious signs of deterioration of the unit.
The burner flames are stable, soft and blue, (dust may cause
orange tips but must not be yellow). The flames should
extend directly outward from the burner without curling,
floating, or lifting off. To examine, turn on the electrical power
and gas. Set the room temperature to the maximum setting.
Burner
Check the burner flames for good adjustment, a stable, soft and
blue flame that is not curling, floating or lifting off.
NOTE: If a strong wind is blowing, it may not be possible to
perform the flame inspection.
WARNING
To avoid personal injury or fire, minimum clearances to
combustible surfaces must be followed.
AIR REQUIREMENTS
WARNING
To avoid property damage, personal injury or death,
sufficient fresh air for proper combustion and ventilation
of flue gases must be supplied.
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
combustion air inlet or the flue hood outlet to become blocked by
leaves, snow, rubbish, or insect (wasps) nests. Never block the
condensing 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.
DANGER
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 unventilated
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.
WARNING
Personal injury or death from asphyxiation can result from
exposure to carbon monoxide. Carbon monoxide or CO is
colorless and odorless gas produced when fuel is not
burned completely or 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:
-Headaches, nausea, dizziness, flu-like symptoms
-Excessive humidity, heavily-frosted windows, a moist,
clammy feeling in the home
-Fireplace smoke will not draw up the chimney
-Flue gases will not draw up the appliance vent pipe
WARNING
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.
