8.Turn on gas and electrical supplies to furnace.

9.Verify igniter operation by initiating furnace control self-test feature or by cycling thermostat.

10.Replace main furnace door.

Procedure 7 — Electrical Controls and Wiring

!WARNING

ELECTRICAL SHOCK HAZARD

Failure to follow this warning could result in personal injury or death.

There may be more than 1 electrical supply to the furnace. Check accessories and cooling unit for additional electrical supplies.

The electrical ground and polarity for 115-v wiring must be maintained properly. Refer to Fig. 17 for field wiring information and to Fig. 20 for furnace wiring information.

NOTE: If polarity is not correct, STATUS LED on furnace control board will flash rapidly and prevent furnace from operating. The control system also requires an earth ground for proper operation of furnace control and flame sensor.

The 24-v circuit contains an automotive-type, 5-amp fuse located on the control. (See Fig. 18.) Any direct shorts of the 24-v wiring during installation, service, or maintenance will cause this fuse to blow. If fuse replacement is required, use ONLY a 5-amp fuse of identical size. The control LED will flash status code 24 when fuse needs to be replaced.

With power to unit disconnected, check all electrical connections for tightness. Tighten all screws on electrical connections. If any smoky or burned connections are found, disassemble connection, clean all parts, strip wire, and reassemble properly and securely.

Reconnect electrical supply to unit and observe unit through 1 complete operating cycle for proper operation.

Procedure 8 — Checking Heat Tape Operation (If Applicable)

In applications where the ambient temperature around the furnace is 32°F (0°C) or lower, freeze protection measures are required. If heat tape has been applied, check to ensure it will operate when low temperatures are present.

!CAUTION

UNIT AND PROPERTY DAMAGE HAZARD

Failure to follow this caution may result in furnace component damage or property damage.

If this furnace is to be operated in an unconditioned space where the ambient temperatures may be 32°F (0°C) or lower, freeze protection measures must be taken. (See Fig. 19.) See CONDENSATE DRAIN PROTECTION section of Installation, Start-Up and Operating Instructions.

NOTE: Heat tape, when used, should be wrapped around the condensate drain trap and drain line. There is no need to use heat tape within the furnace casing. Most heat tapes are temperature activated, and it is not practical to verify the actual heating of the tape. Check the following:

1.Check for signs of physical damage to heat tape such as nicks, cuts, abrasions, gnawing by animals, etc.

2.Check for discolored heat tape insulation. If any damage or discolored insulation is evident, replace heat tape.

3.Check that heat tape power supply circuit is on.

Procedure 9 — Winterizing

!CAUTION

UNIT DAMAGE HAZARD

Failure to follow this caution may result in furnace component damage.

Freezing condensate left in the furnace will damage the furnace.

If the furnace will be off for an extended period of time in a structure where the temperature will drop to 32°F (0°C) or below, winterize as follows:

1.Turn off electrical supply to furnace.

2.Remove main furnace door.

3.Disconnect the 1/2” I.D. rubber hose from the vent drain fitting (or tee) that is located downstream of the combustion blower. Insert a funnel into the hose and pour four (4) ounces of sanitary type (RV) antifreeze into the condensate trap. Reconnect the 1/2” I.D. rubber hose to the stub the vent drain fitting. Secure with the hose clamp.

!CAUTION

UNIT DAMAGE HAZARD

Failure to follow this caution may result in unit component damage.

Do not use ethylene glycol (Prestone II antifreeze/coolant or equivalent automotive type). Failure of plastic components may occur.

4.Disconnect the 5/8” I.D. rubber hose from the condensate trap. Insert a funnel into the hose and pour four (4) ounces of sanitary type (RV) antifreeze into the plastic transition box. Squeeze the hose together near the and quickly reconnect the 5/8” I.D. rubber hose to the stub on the condensate trap. Secure with the hose clamp.

5.When you return home, your furnace will be ready to start, as it is not necessary to drain the antifreeze from the furnace.

WIRING DIAGRAM

See Fig. 20 for Wiring Diagram.

TROUBLESHOOTING

Use the Troubleshooting Guide, the status code LED on the control and the Component Test to isolate furnace operation problems.

A. Status Codes

For an explanation of status codes, refer to service label located on front of blower door or Fig. 21.

NOTE: Removing the blower access door will open the blower access door switch and terminate 115-v power to the control. This will erase the stored status code.

NOTE: NO thermostat signals should be present at control and all blower off delays must be completed to view previous codes.

359AAV specifications

The Bryant 359AAV is a cutting-edge heating and cooling solution designed to deliver exceptional comfort, energy efficiency, and reliability for residential applications. With its innovative advancements and superior engineering, the Bryant 359AAV stands out in the competitive HVAC market.

One of the main features of the Bryant 359AAV is its two-stage heating and cooling system. This allows the unit to operate at two different levels of capacity, ensuring more consistent temperatures throughout your home. By running at a lower capacity most of the time, it can achieve greater energy efficiency compared to single-stage systems, and only ramps up to full power when there's a significant demand for heating or cooling. This results in improved comfort and lower energy bills.

Equipped with a variable-speed compressor, the Bryant 359AAV can adjust its speed to match the specific heating or cooling needs of your home. This feature not only enhances the system's efficiency but also reduces noise levels, making it one of the quietest units in its class. The advanced sound-dampening technology minimizes operational sounds, allowing homeowners to enjoy a peaceful indoor environment.

The Bryant 359AAV also features a high SEER (Seasonal Energy Efficiency Ratio) rating. This rating is crucial for determining the unit's efficiency during the cooling season. A higher SEER rating means that the unit consumes less energy for the same amount of cooling output, which helps in lowering utilities. This is particularly beneficial for homeowners looking to reduce their overall energy consumption and carbon footprint.

Another significant characteristic of the Bryant 359AAV is its advanced indoor air quality options. The system can be equipped with filters and purifiers to ensure that the air circulating in your home is clean and healthy. Enhanced filtration helps in capturing allergens, pollutants, and other harmful particles, improving the overall air quality.

Overall, the Bryant 359AAV is characterized by its durability and modern design. Built with high-quality materials, it is designed to withstand harsh weather conditions and provide reliable service for years. The unit’s compact footprint allows for versatile installation options, making it suitable for various home layouts.
