4.Follow the lighting instructions. Place the appliance being inspected in operation. Adjust thermostat so appliance shall operate continuously.

5.Test for draft hood equipped appliance spillage at the draft hood relief opening after 5 minutes of main burner operation. Use the flame of a match or candle.

6.After it has been determined that each appliance connected to the venting system properly vents when tested as outlined above, return doors, windows, exhaust fans, fireplace dampers, and any other gas-burning appliance to their previous conditions of use.

7.If improper venting is observed during any of above tests, the venting system must be corrected.

Vent system or vent connectors may need to be resized. For any other appliances when resizing vent systems or vent connectors, system or connector must be sized to approach minimum size as determined using appropriate table found in the NFGC or NSCNGPIC.

B. Combustion-Air and Vent Piping

GENERAL

Combustion-air and vent pipe, fittings, primers, and solvents must conform to American National Standards Institute (ANSI) standards and American Society for Testing and Materials (ASTM) standards. See Table 6 for approved materials for use in the U.S.A. See Table 7 for maximum pipe lengths and Fig. 39, 40, 41, 42, and 43 for exterior piping arrangements.

In Canada, construct all combustion-air and vent pipes for this unit of CSA or ULC certified schedule-40 PVC, PVC-DWV or ABS-DWV pipe and pipe cement. SDR pipe is NOT approved in Canada.

355MAV specifications

The Bryant 355MAV is a remarkable model that stands out in the HVAC (heating, ventilation, and air conditioning) industry for its efficiency, reliability, and advanced technology. This unit is specifically designed to provide homeowners with excellent comfort while maintaining energy efficiency, making it an ideal choice for residential applications.

One of the standout features of the Bryant 355MAV is its variable speed compressor. This technology allows the system to adjust its cooling output based on the current temperature needs of the home. By operating at multiple speed levels, the compressor can maintain a more consistent indoor climate while using significantly less energy than traditional single-speed systems. This capability translates to lower energy bills and enhanced comfort.

Additionally, the Bryant 355MAV integrates an advanced control system that offers precise temperature regulation. Homeowners can easily set their desired indoor conditions, and the thermostat will communicate with the system to ensure optimal performance. This smart technology not only enhances comfort but also extends the lifespan of the unit by preventing unnecessary strain during operation.

The 355MAV also features significant advancements in sound reduction technology. Designed with noise-absorbing materials and a quiet operation mode, this unit ensures that indoor comfort is maintained without the disruption of loud operational sounds. This makes it a perfect choice for residential settings, particularly in areas where noise sensitivity is a concern.

Energy efficiency is another key characteristic of the Bryant 355MAV. The unit is certified with a high Seasonal Energy Efficiency Ratio (SEER) rating, which means it meets strict energy consumption standards. This not only reflects its eco-friendliness but also contributes to significant savings on utility bills over time.

Moreover, the Bryant 355MAV uses environmentally friendly refrigerants that comply with EPA regulations, further solidifying its commitment to sustainability. This, combined with durable construction and a reliable warranty, ensures that homeowners can expect lasting performance from the system.

In conclusion, the Bryant 355MAV offers an impressive array of features, including a variable speed compressor, advanced control systems, sound reduction technology, and high energy efficiency. These characteristics make it an exceptional option for those seeking a reliable and efficient HVAC solution in their homes. With its commitment to comfort, savings, and sustainability, the Bryant 355MAV continues to be a popular choice among homeowners looking to enhance their indoor environments.
