should be taken to prevent possible vent system ice blockage
that could result in safety shutdown of the burners:
1.
Adjust to the highest achievable temperature rise within the
rise and static pressure ranges specified on the rating plate.
2.
Make sure there are no leaks of outside air into the return air
system.
3.
Keep the outside louver grill as free as possible of any ice that
may form and obstruct the flue outlet.
THE GAS BURNER IN THIS GAS-FIRED
EQUIPMENT IS DESIGNED AND EQUIPPED TO
PROVIDE SAFE AND COMPLETE COMBUSTION.
HOWEVER, IF THE INSTALLATION DOES
NOT PERMIT THE BURNER TO RECEIVE
THE PROPER SUPPLY OF COMBUSTION
AIR, COMPLETE COMBUSTION MAY NOT
OCCUR. THE RESULT IS INCOMPLETE
COMBUSTION THAT PRODUCES CARBON
MONOXIDE, A POISONOUS GAS THAT
CAN CAUSE DEATH. SAFE OPERATION OF
DIRECT-FIRED GAS BURNING EQUIPMENT
REQUIRES A PROPERLY OPERATING VENT
SYSTEM THAT VENTS ALL FLUE PRODUCTS
TO THE OUTSIDE ATMOSPHERE. FAILURE
TO PROVIDE VENTING WILL RESULT IN A
HEALTH HAZARD WHICH COULD CAUSE
SERIOUS PERSONAL INJURY OR DEATH.
ALWAYS COMPLY WITH THE COMBUSTION
AIR REQUIREMENTS IN THE INSTALLATION
CODES. COMBUSTION AIR AT THE BURNER
SHOULD BE REGULATED ONLY BY
MANUFACTURER-PROVIDED EQUIPMENT.

Maintenance and Service
The 16" x 25" x 1" filter on the cooling chassis must be maintained
regularly to assure that the unit provides optimal performance and
energy efficiency. The intervals between replacing depends entirely
on the cleanliness of the return air to the unit and the time that the
indoor blower operates. The air filter is accessible by removing the
lower access panel. The filter should be inspected and replaced as
needed and is not washable. Substituting the air filter with media
other than the type provided with the unit is not recommended,
since other materials may cause additional static pressure, which
could reduce the air delivery of the unit.
The unit should never be
operated without the air filter and access panels in place
.
Cooling Chassis
The cooling chassis contains all items related to the cooling
functions of the unit, and also contains the indoor blower and
motor for the heating function. For extensive servicing, qualified
personnel may choose to remove the cooling chassis from the unit
and take it to a work area. Spare chassis are recommended so that
extensive servicing can be performed outside the living space. This
will prevent introducing dirt or doing damage in the living area, and
could help to eliminate significant disruption of the air conditioning
and heating functions in the living areas.
The indoor blower motor and the outdoor fan motor have
permanently lubricated bearings and do not require routine service.
The refrigeration system is sealed and factory charged with R-410A
so that routine maintenance is not required. The electrical controls
do not require routine service. Cleaning of the outdoor coil, indoor
