!WARNING

CARBON MONOXIDE POISONING HAZARD

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

The operation of exhaust fans, kitchen ventilation fans, clothes dryers, attic exhaust fans or fireplaces could create a NEGATIVE PRESSURE CONDITION at the furnace. Make-up air MUST be provided for the ventilation devices, in addition to that required by the furnace. Refer to Carbon Monoxide Poisoning Hazard warning in venting section of these instructions to determine if an adequate amount of make-up air is available.

The requirements for combustion and ventilation air depend upon whether or not the furnace is located in a space having a volume of at least 50 cu/ft. per 1,000 Btuh input rating for all gas appliances installed in the space.

SSpaces having less than 50 cu/ft. per 1,000 Btuh re- quire the OUTDOOR COMBUSTION AIR METHOD.

SSpaces having at least 50 cu/ft. per 1,000 Btuh may use the INDOOR COMBUSTION AIR, STANDARD or

KNOWN AIR INFILTRATION METHOD.

Outdoor Combustion Air Method

1.Provide the space with sufficient air for proper combus- tion, ventilation, and dilution of flue gases using perman- ent horizontal or vertical duct(s) or opening(s) directly communicating with the outdoors or spaces that freely communicate with the outdoors.

2.Fig. 7 illustrates how to provide TWO OUTDOOR OPENINGS, one inlet and one outlet combustion and ventilation air opening, to the outdoors.

e. One opening MUST commence within 12 in. (300 mm) of the ceiling and the second opening MUST commence within 12 in. (300 mm) of the floor.

f.Size openings and ducts per Fig. 7 and Table 2.

g.TWO HORIZONTAL DUCTS require 1 sq./in. of free area per 2,000 Btuh (1,100 mm2/kW) of combined input for all gas appliances in the space per Fig. 7 and Table 2.

h.TWO OPENINGS OR VERTICAL DUCTS require 1 sq./in. of free area per 4,000 Btuh (550 mm2/kW) for combined input of all gas appliances in the space per Fig. 7 and Table 2.

3.ONE OUTDOOR OPENING requires:

a.1 square inch of free area per 3,000 Btuh (734 mm2/kW) for combined input of all gas appliances in the space per Table 2 and

b.Not less than the sum of the areas of all vent connect- ors in the space.

The opening shall commence within 12 in. (300 mm) of the ceiling. Appliances in the space shall have clearances of at least 1 in. (25 mm) from the sides and back and 6 in. (150 mm) from the front. The opening shall directly communicate with the outdoors or shall communicate through a vertical or horizontal duct to the outdoors or spaces (crawl or attic) that freely communicate with the outdoors.

Indoor Combustion Air NFPA & AGA

Standard and Known-Air-Infiltration Rate Methods

Indoor air is permitted for combustion, ventilation, and dilution, if the Standard or Known-Air-Infiltration Method is used.

!WARNING

CARBON MONOXIDE POISONING HAZARD Failure to follow this warning could result in death and/or personal injury.

Many homes require air to be supplied from outdoors for furnace combustion, ventilation, and dilution of flue gases. The furnace combustion air supply must be provided in accordance with this instruction manual.

310AAV specifications

The Bryant 310AAV and 310JAV are high-efficiency air conditioning and heating systems designed for residential and light commercial applications. These models embody Bryant's commitment to delivering reliable comfort solutions while prioritizing energy efficiency and performance.

One of the standout features of the Bryant 310AAV and 310JAV is their impressive Seasonal Energy Efficiency Ratio (SEER) ratings. The higher the SEER, the more efficient the unit is in using electricity to cool your space. The Bryant 310AAV boasts a SEER rating of up to 16, while the 310JAV offers a slightly lower rating. This efficiency translates into cost savings on monthly energy bills while ensuring indoor comfort throughout the year.

Both models utilize advanced technologies, including two-stage heating and cooling capabilities. This means that the systems can adjust their operation based on the heating or cooling needs of a space, providing optimal temperature control while reducing energy waste. The two-stage operation also contributes to quieter operation levels, making these units suitable for residential settings where noise is a concern.

The 310AAV and 310JAV are equipped with variable-speed compressors, which further enhance their efficiency and comfort levels. The variable-speed technology allows the system to operate at different speeds, ensuring consistent temperature management and reducing the frequency of on-and-off cycling. This leads to steadier indoor temperatures and improved humidity control.

In addition to their performance features, Bryant places a strong emphasis on durability and dependability. The units are constructed with high-quality materials that are designed to withstand various environmental conditions. Features such as a weather-resistant cabinet and an efficient coil design help protect the units from wear and tear, ensuring long-lasting performance.

The implementation of environmentally friendly refrigerant options is another characteristic that demonstrates Bryant's commitment to sustainability. Both the 310AAV and 310JAV utilize R-410A refrigerant, which has a lower environmental impact compared to older refrigerants, aligning with modern standards for eco-friendly HVAC systems.

Overall, the Bryant 310AAV and 310JAV represent a blend of efficiency, advanced technology, and durability. With their attractive SEER ratings, two-stage operation, variable-speed capabilities, and commitment to sustainability, these models stand out as excellent choices for homeowners and businesses looking to enhance their heating and cooling solutions while keeping energy consumption in check. Whether for residential comfort or light commercial use, these Bryant units promise reliability and performance for years to come.
