COMFORTT92 FEATURES / BENEFITS
Serpentufft— Exclusive Serpentuff coating, a patented
polypropylene laminate is used on the secondary heat exchanger.
Power HeattIgniter — Carrier’s unique SiN igniter is not only
physically robust but it is also electrically robust. It is capable of
running at line voltage and does not require complex voltage
regulators as do other brands. This unique feature further enhances
the reliability of Comfortt92 gas furnace and continues Carrier’s
tradition of technology leadership and innovation in providing a
reliable and durable product.
ComfortFant— Improves comfort all year long by allowing the
homeowner to select different fan speeds during continuous fan
operation to achieve more or less airflow. This is done right at the
thermostat.
SmartEvapt— This feature allows your system to reduce
summertime humidity levels by nearly 10% over standard systems.
Media Filter Cabinet — Enhanced indoor air quality in your
home is made easier with our media filter cabinet—a standard
accessory on all Deluxe furnaces. When installed as a part of your
system, this cabinet allows for easy and convenient addition of a
Carrier highefficiency air filter.

furnace operation. Equipped with a component test feature and
status indicator light to assist in troubleshooting. Microprocessor
blower control times blower start after main burners ignite to
eliminate cold air blowing into rooms.

furnace. This provides added flexibility to meet diverse installation
needs.
Insulated Blower Compartment —The acoustical insulation
reduces air and motor noise to promote quiet operation.
Combustion Products Venting — The combustion--air and vent
pipes can terminate through a side wall or through the roof when
used with a factory authorized vent termination kit.
Insulation — Foil--faced insulation in heat exchanger section of
the casing minimizes heat loss.
Bottom Closure — Factory--installed for side return; easily
removable for bottom return.
Filter — Cleanable filter with retainer is standard.
Blower Access Panel Switch — Shuts off all 115--v power
through furnace components whenever blower access panel is
opened.
Casing — One piece, seamless wrap--around construction of
heavy, galvanized steel resists corrosion.
Adjustable Blower Speed — For precise airflow selection of
heating or cooling operation.
Monoport Burners — The burners are finely tuned for smooth,
quiet combustion plus economical gas usage.
Slow Opening Redundant Gas Valve — Shuts off gas to burners
if one of the valves fails to close completely for any reason. The
slow opening feature reduces start--up noise from rapid ignition.

efficiency rating certified. The Comfortt92 meets California Air
Quality Management District emission requirements. Except for
the 140 size unit, all Comfortt92 models can be installed in a
manufactured (mobile) home when the optional kit is used in direct
vent (2--pipe) application. Refer to Vent Table, for elevation
