Product Data

4--WAY MULTIPOISE DESIGN ALLOWS
MORE APPLICATIONS

the furnace resulting in lower electrical usage. The high
efficiency achieved by superior heat transfer is made only
better—by optimizing the efficient ECM motor speed tap
locations.

A standard media filter cabinet accessory is provided with the
Plus 90x in order to provide an opportunity to enhance indoor air
quality. As with all other Bryant furnaces, this model is designed
to work as a part of the total home comfort system which includes
elements for cooling, air cleaning, humidification, ventilation and
zoning. Boosting the unit’s efficiency with the ECM motor and
Bryant’s deluxe features show the Plus 90x has been designed
with the homeowner in mind.

PLUS 90X FEATURES & BENEFITS

EverlasticTM— Exclusive Everlastic coating, a patented

polypropylene laminate is used on the secondary heat exchanger
and greatly reduces maintenance.

Perfect Light™ Igniter — Bryant’s unique Perfect Light™
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 the Plus 90x gas
furnace and continues Bryant’s tradition of technology leadership
and innovation in providing a reliable and durable product.

FanOn™ — Improves comfort all year long by allowing the
homeowner to select different fan speeds during continuous fan

A05085

operation to achieve more or less airflow. This is done right at the
thermostat.

A UNIQUE SEER SOLUTION

The Plus 90x is an exciting addition to your product line. This
high--efficiency 4--way multipoise design furnace allows more
applications while the ECM motor and Bryant’s control logic
combine to provide a SEER increase of up to 1.5 points.*

Some of Bryant’s best--engineered components contribute to the
efficient performance of this condensing furnace. The Plus 90x
utilizes Power Lightt hot surface ignition (HSI), which ignites
the burners directly. HSI eliminates gas waste that typical
continuous--pilot designs can bring. Hot surface ignition has
proven to contribute to reliable start--up and operation of Bryant
furnaces.

Another deluxe feature included with this furnace is Bryant’s
trusted Everlastict secondary heat exchanger; a patented
polypropylene laminate that provides exceptional heat transfer
and corrosion resistance. Using the exclusive flow--through
design, the secondary heat exchanger reduces the pressure drop in

*as compared to the Air--- Conditioning, Heating and Refrigeration Institute’s standard coil--- only rating (A/Cs up to 3.5 tons) when paired with selected Bryant
evaporator coils.

SmartEvap™ — 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
Bryant high--efficiency air filter.

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

Direct or Non--direct Venting —ThePlus 90x can be installed
as a 1 pipe/Non--Direct vent (except 140 size unit and in
manufactured/mobile home installations) or 2 pipe/Direct vent
furnace. All direct vent Plus 90x models can be installed in a
manufactured (mobile) home when the optional kit is used. This
provides added flexibility to meet diverse installation needs.

Casing — One piece, seamless wrap--around construction of
heavy, galvanized steel that resists corrosion.

Adjustable Blower Speed — For precise airflow selection of
heating or cooling operation.

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.

slow opening feature reduces start--up noise from rapid ignition.

Quality Registration —ThePlus 90x is engineered and
manufactured under an ISO 9001 registered quality system.

Certifications —ThePlus 90x Model units are CSA (A.G.A.
and C.G.A.) design certified for use with natural and propane
gases. The furnace is factory--shipped for use with natural gas. A
CSA (A.G.A./C.G.A.) listed gas conversion kit is required to
convert furnace for use with propane gas. The efficiency is
GAMA efficiency rating certified. The Plus 90x meets California
Air Quality Management District emission requirements. Refer to
Vent Table, for elevation limitations.

THERMOSTATS

AND ZONING

Available in programmable and

non-programmable models,
Bryant thermostats maintain a
constant, comfortable tempera­ture level in the home.

For the ultimate in home comfort,
Bryant’s 2, 4, and 8-zone systems
allow temperature control of indi­vidual “zones” of the home. This is
accomplished through a series of
electronic dampers and

remote room sensors.

4-zone system is shown.

HUMIDIFIER

By adding moisture to winter-dry
air, a Bryant humidifier can often
improve comfort and keep
furniture, rugs, and draperies in
better condition. Moisturizing
household air also helps to retain
normal body heat and provides
comfort at lower temperatures.

ENERGY/HEAT RECOVERY

VENTILATOR

Bryant’s energy or heat recovery
ventilators exhaust stale indoor
air and provide fresh outdoor air
to the home while minimizing
heat loss and humidity level.
Especially useful for today’s
tighter constructed houses.
