The Standard Method:

1.The space has no less volume than 50 cu/ft. per 1,000 Btuh of the maximum input ratings for all gas appliances installed in the space and

2.The air infiltration rate is not known to be less than 0.40 air changes per hour (ACH).

The Known Air Infiltration Rate Method shall be used, if the infiltration rate is known to be:

1.Less than 0.40 ACH and

2.Equal to or greater than 0.10 ACH

Infiltration rates greater than 0.60 ACH shall not be used. The minimum required volume of the space varies with the number of ACH and shall be determined per Table 3 or Equations 1 and 2. Determine the minimum required volume for each appliance in the space and add the volumes together to get the total minimum required volume for the space.

Table 3 - Minimum Space Volumes were determined by using the following equations from the National Fuel Gas Code ANSI

Z223.1-2009/NFPA 54-2009, 9.3.2.2:

Iother = combined input of all other than fan-assisted appliances in Btuh/hr

Ifan = combined input of all fan-assisted appliances in Btuh/hr ACH = air changes per hour (ACH shall not exceed 0.60.) The following requirements apply to the Standard Method and to the Known Air Infiltration Rate Method.

1.Adjoining rooms can be considered part of a space if:

a.There are no closeable doors between rooms.

b.Combining spaces on same floor level. Each opening shall have free area of at least 1 in.2/1,000 Btuh (2,000 mm2/kW) of the total input rating of all gas appliances in the space, but not less than 100 in.2 (0.06 m2). One opening shall commence within 12 in. (300 mm) of the ceiling and the second opening shall commence within 12 in. (300 mm) of the floor. The minimum dimension of air openings shall be at least 3 in. (80 mm). (See Fig. 8.)

c.Combining space on different floor levels. The volumes of spaces on different floor levels shall be considered as communicating spaces if connected by one or more permanent openings in doors or floors having free area of at least 2 in.2/1,000 Btuh (4,400 mm2/kW) of total input rating of all gas appliances.

2.An attic or crawlspace may be considered a space that freely communicates with the outdoors provided there are adequate permanent ventilation openings directly to out- doors having free area of at least 1-in.2/4,000 Btuh of total input rating for all gas appliances in the space.

3.In spaces that use the Indoor Combustion Air Method, in- filtration should be adequate to provide air for combus- tion, permanent ventilation and dilution of flue gases.

However, in buildings with unusually tight construction, additional air MUST be provided using the methods de- scribed in the Outdoor Combustion Air Method section.

Unusually tight construction is defined as Construction with:

a.Walls and ceilings exposed to the outdoors have a con- tinuous, sealed vapor barrier. Openings are gasketed or sealed and

b.Doors and openable windows are weatherstripped and

c.Other openings are caulked or sealed. These include joints around window and door frames, between sole plates and floors, between wall-ceiling joints, between wall panels, at penetrations for plumbing, electrical and gas lines, etc.

Combination of Indoor and Outdoor Air

1.Indoor openings shall comply with the Indoor Combus- tion Air Method below and,

2.Outdoor openings shall be located as required in the Out- door Combustion Air Method mentioned previously and,

3.Outdoor openings shall be sized as follows:

a.Calculate the Ratio of all Indoor Space volume divided by required volume for Indoor Combustion Air Method below.

b.Outdoor opening size reduction Factor is 1 minus the Ratio in a. above.

c.Minimum size of Outdoor openings shall be the size required in Outdoor Combustion Air Method above multiplied by reduction Factor in b. above. The min- imum dimension of air openings shall be not less than 3 in. (80 mm).

INSTALLATION

UPFLOW INSTALLATION

Bottom Return Air Inlet

These furnaces are shipped with bottom closure panel installed in bottom return-air opening. Remove and discard this panel when bottom return air is used. To remove bottom closure panel, perform the following:

1.Tilt or raise furnace and remove 2 screws holding bottom filler panel. (See Fig. 9.)

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.
