Venting System Length Calculations

The maximum length for each vent pipe (inlet or exhaust) equals the Maximum Equivalent Vent Length (MEVL) from Table 1 or Table 3 minus the number of elbows multiplied by the deduction for each elbow in Table 2.

Standard vent terminations and concentric vent terminations count for zero deductions. See Vent Manufacturers’ data for equivalent lengths of flexible vent piping.

DO NOT ASSUME that one foot of flexible vent pipe is equivalent to one foot of standard PVC vent pipe.

Example

A direct-vent 60,000 Btuh furnace installed at 2100 ft. (640 M) with 2-in.(51 mm) vent piping. Venting system includes, FOR EACH PIPE, (3) 90_ long radius elbows, (2) 45_ long radius elbows and a concentric vent kit.

915S specifications

The Bryant 915S is an innovative and high-efficiency air conditioner that caters to the needs of homeowners seeking comfort and energy savings. This unit is designed to provide optimal cooling performance while being environmentally friendly.

One of the main features of the Bryant 915S is its exceptional Seasonal Energy Efficiency Ratio (SEER) rating, which can reach up to 19. This high rating demonstrates the unit's ability to deliver considerable energy savings over traditional air conditioning systems. With such efficiency, homeowners can enjoy lower energy bills while ensuring a comfortable indoor climate.

The Bryant 915S employs advanced two-stage cooling technology, allowing it to operate at two distinct capacities. During periods of high demand, the system can run at full capacity, quickly cooling down the space. During milder weather, it operates at a lower capacity, maintaining comfort while consuming less energy. This feature helps reduce wear and tear on the system, potentially extending its lifespan.

Another remarkable technology integrated into the Bryant 915S is the use of variable-speed operation. This allows the compressor to adjust its speed in response to the current demands of the home. By modulating the cooling output, the unit can maintain a consistent temperature and humidity level, enhancing comfort while further increasing energy efficiency.

Durability is a key characteristic of the Bryant 915S, built with heavy-duty materials and a robust design. The unit includes a spine fin coil that provides excellent heat exchange while resisting corrosion. Furthermore, its baked-on powder paint finish ensures that the outdoor unit can withstand harsh weather conditions, maintaining its aesthetic appeal and functionality over time.

Additionally, the Bryant 915S features a quiet operation, thanks to the sound-dampening technology incorporated into its design. This characteristic makes it suitable for residential areas where noise can be a concern, allowing homeowners to enjoy a cool and peaceful environment.

In summary, the Bryant 915S is an advanced air conditioning solution, featuring high SEER ratings, two-stage cooling, variable-speed operation, and durable construction. These technological advancements and characteristics make it an excellent choice for homeowners looking for energy-efficient cooling solutions without sacrificing comfort.
