6.Determine appropriate length, cut, and connect tube.

7.Clamp tube to relief port connection.

E. Condensate Trap Freeze Protection

Refer to Condensate Drain Protection section for recommendations and procedures

F. Construct a Working Platform

Construct working platform where all required furnace clearances are met. (See Fig. 3 and 10.)

CAUTION: The condensate trap MUST be installed below furnace. See Fig. 4 for dimensions. The drain connection to condensate trap must also be properly sloped to an open drain.

NOTE: Combustion-air and vent pipes are restricted to a minimum length of 5 ft. (See Table 6.)

NOTE: A 12-in. minimum offset pipe section is recommended with short (5 to 8 ft) vent systems. This recommendation is to reduce excessive condensate droplets from exiting the vent pipe. (See Fig. 10 or 29.)

LOCATION

PROCEDURE 1—GENERAL

When a furnace is installed so that supply ducts carry air to areas outside the space containing the furnace, return air must also be handled by ducts sealed to furnace casing. The ducts terminate outside the space containing the furnace to ensure there will not be a negative pressure condition within equipment room or space. Furnace may be located in a confined space without special provisions for dilution or ventilation air. This furnace must be installed so electrical components are protected from water.

Drainage

NOTE: For proper furnace operation, install furnace so that it is level or pitched forward within 1/2-in. to ensure proper condensate drainage from secondary heat exchangers. (See Fig. 12.)

NOTE: These furnaces are designed for a minimum continuous return-air temperature of 60°F or intermittent operation down to 55°F such as when used with a night setback thermostat. Return-air temperature must not exceed a maximum of 85°F. Failure to follow these return-air temperature limits may affect reliability of heat exchangers, motors, and controls. (See Fig. 13.)

Locate furnace as close to center of air distribution system as possible.

Locate furnace so combustion-air pipe lengths are not exceeded. Refer to Table 6.

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.
