Bryant 355CAV Horizontal Right Supply-Airdischarge Applications, Construct a Working Platform

1.Disconnect collector box pressure tube (pink label) attached to High Pressure Switch.

2.Use smaller diameter tube (factory-suppled in loose pars bag) to extend tube disconnected in Item 1.

3.Route extended tube:

a.Behind inducer housing.

b.Between blower shelf and inducer housing.

4.Determine appropriate lenght, cut, and reconnect tube to High Pressure Switch connections labeled COLLECTOR BOX.

Condensate Trap Freeze Protection

Refer to Condensate Drain Protection section for recommendations and procedures.

Construct a Working Platform

Construct working platform where all required furnace clearances are met. (See Fig. 3 and 12 or 13.)

!CAUTION

UNIT OPERATION HAZARD

Failure to follow this caution may result in intermittent unit operation.

The condensate trap MUST be installed below furnace. See Fig. 6 for dimensions. The drain connection to condensate trap must also be properly sloped to an open drain.

NOTE: A 12-in. (304.8mm) minimum offset pipe section is recommended with short (5 to 8 ft or 1.5 M to 2.4 M) vent systems. This recommendation is to reduce excessive condensate droplets from exiting the vent pipe. (See Fig. 12, 13, or 44.)

HORIZONTAL RIGHT

(SUPPLY-AIR DISCHARGE) APPLICATIONS

A horizontal right furnace application is where furnace blower is located to the left of combustion and controls section of furnace, and conditioned air is discharged to the right.

!CAUTION

PROPERTY DAMAGE HAZARD

Failure to follow this caution may result in property damage.

Local codes may require a drain pan under entire furnace and condensate trap when a condensing furnace is used in an attic application or over a finished ceiling.

NOTE: In Canada, installations shall be in accordance with current NSCNGPIC and/or local codes.

NOTE: The auxiliary junction box (J-box ) MUST be relocated to opposite side of furnace casing. (See Fig. 14.) See Electrical Connection section for J-box relocation.

Fig. 14 - Horizontal Right Tube Configuration

The condensate trap must be removed from the factory-installed blower shelf location and relocated in selected application location as shown in Fig. 2 or 14.

To relocate condensate trap from the blower shelf to desired location, perform the following:

1.Remove three tubes connected to condensate trap.

2.Remove trap from blower shelf by gently pushing tabs inward and rotaing trap.

!WARNING

CARBON MONOXIDE POISONING HAZARD

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

Casing hole filler cap must be installed in blower shelf hole when condensate trap is relocated to prevent combustion products being drawn in from appliances in the equipment room.

3.Install casing hole filler cap (factory-supplied in loose parts bag) into blower shelf hole where trap was removed.

4.Install condensate trap into right-hand side casing hole by inserting tube connection stubs through casing hole an rotating until tabls snap into locking position.

5.Fill unused condensate trap casing holes with plastic filler caps (factory-supplied in loose parts bag).
