Product Data  
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.  
4--WAY MULTIPOISE DESIGN ALLOWS  
MORE APPLICATIONS  
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  
TM  
Everlastic  
Exclusive Everlastic coating,  
a
patented  
polypropylene laminate is used on the secondary heat exchanger  
and greatly reduces maintenance.  
Perfect LightIgniter — 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  
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.*  
SmartEvap— This feature allows your system to reduce  
summertime humidity levels by nearly 10% over standard  
systems.  
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.  
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.  
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.

1. Burner sight glass for viewing burner flame.  
11. Heavy--duty blower circulates air across the heat  
exchangers to transfer heat into the home.  
2. Burner assembly (inside), operates with energy--sav-  
ing, inshot burners and hot surface igniter for safe,  
dependable heating.  
12. Air filter and retainer may be used for side or bottom  
return application.  
3. Combustion--air intake connection to ensure contam-  
inant--free air (right or left side).  
13. Rollout switch (manual reset) to prevent overtemper-  
ature in burner area.  
4. Redundant gas valve, safe, efficient, features 1 gas  
control with 2 internal shutoff valves.  
14. Primary serpentine heat exchanger (inside). Stretches  
fuel dollars with the S--shaped heat--flow design. Sol-  
id weld--free construction of corrosion--resistant alu-  
minized steel means reliability.  
5. Junction box for 115--v electrical power supply.  
(right or left side)  
15. A 3--amp fuse provides electrical and component  
protection.  
6. Vent outlet uses sealed PVC pipe to carry vent gases  
from the furnace’s combustion system (right or left  
side).  
16. Light emitting diode (LED) on control center. Code  
lights are for diagnosing furnace operation and ser-  
vice requirements.

ensure durability.  
17. Control center.  
18. Blower access panel safety interlock switch.  
8. Pressure switch ensures adequate flow of flue  
products through furnace and out vent system.  
19. Transformer (24v) behind control center provides  
low--voltage power to furnace control center and  
thermostat.  
9. Inducer motor pulls hot flue gases through the heat  
exchangers, maintaining negative pressure for added  
safety.  
20. Power choke (used with 1 HP and 3/4 HP motors.)

furnace coil which can also  
replace the downflow subbase  
when installing select Bryant  
furnaces on combustible flooring  
in the downflow orientation.

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.  
By adding moisture to winter-dry  
air, a Bryanthumidifier 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.  
Cleans the air of smoke, dirt, and  
many pollens commonly found.  
Saves decorating and cleaning  
expenses by keeping carpets,  
furniture, and drapes cleaner.  
For the ultimate in home comfort,  
Bryant’s 2, 4, and 8-zone systems  
allow temperature control of indi-  
vidual “zones” of the home. This is  
accomplished through a series of  
electronic dampers and

{Gas input ratings are certified for elevations to 2000 ft. (610 M). For elevations above 2000 ft. (610 M), reduce ratings 2% for each 1000 ft. (305 M) above sea  
level. In Canada, derate the unit 5% for elevations 2000 to 4500 ft. (610 to 1372 M) above sea level.  
}Airflow shown is for bottom only return---air supply with factory supplied 3/4---in. (19 mm) washable filter(s).  
For air delivery above 1800 CFM, see Air Delivery table for other options.  
An airflow reduction of up to 7% may occur when using the factory---specified 4 5/16---in. (110 mm) wide, high efficiency media filter.  
For best furnace efficiency when using the 4---5/16---in. (110 mm) wide media filter, adjust the blower speed tap to near the mid---point of the rise range.

] Airflow shown is for bottom only return---air supply with factory supplied 3/4---in. (19 mm) washable filter(s).  
For air delivery above 1800 CFM, see Air Delivery table for other options.  
An airflow reduction of up to 7% may occur when using the factory---specified 4 5/16---in. (110 mm) wide, high efficiency media filter.  
For best furnace efficiency when using the 4 5/16---in. (110 mm) wide media filter, adjust the blower speed tap to near the mid---point of the rise range.  
For horizontal and downflow applications, use one side or bottom or bottom only as airflow reference.

* Disk usage-Unless otherwise specified, use perforated disk assembly (factory-supplied in loose parts bag).  
# If one disk is stated, separate 2 halves of perforated disk assembly and use shouldered disk half. When using shouldered disk half, install screen side toward inlet box.  
† Wide radius elbow.  
‡ Vent sizing for Canadian installations over 4500 ft (1370 M) above sea level are subject to acceptance by the local authorities having jurisdiction. NA-Not Allowed;  
pressure switch will not make.  
NOTES:  
1. Do not use pipe size greater than those specified in table or incomplete combustion, flame disturbance, or flame sense lockout may occur.  
2. Size both the combustion-air and vent pipe independently, then use the larger diameter for both pipes.  
3. Assume two 45° elbows equal one 90° elbow. Wide radius elbows are desirable and may be required in some cases.  
4. Elbows and pipe sections within the furnace casing and at the vent termination should not be included in vent length or elbow count.  
5. The minimum pipe length is 5 ft (1.5 M) for all applications.  
6. Use 3-in. (76 mm) diameter vent termination kit for installations requiring 4-in (102 mm) diameter pipe.
