Bryant 355CAV installation instructions Horizontal Right SUPPLY-AIR Discharge Applications

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 in- ward and rotating 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 tabs through casing hole and ro- tating until tabs snap into locking position.

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

NOTE: See Fig. 14 or tube routing label on main furnace door to check for proper connections.

1.Collector Box Drain Tube

a.Remove factory-installed plug from LOWER collector box drain tube (blue and white striped label).

b.Install removed clamp and plug into UPPER collector box drain tube (blue label) which was previously connec- ted to condensate trap.

c.Connect LOWER collector box drain tube (blue and white striped label) to condensate trap. Tube does not need to be cut.

d.Clamp tube to prevent any condensate leakage.

2.Inducer Housing Drain Tube

(a.)Remove factory-installed cap and clamp from LOWER inducer housing drain connection.

(b.)Remove and discard UPPER (molded) inducer housing drain tube which was previously con- nected to condensate trap.

(c.)Install cap and clamp on UPPER inducer hous- ing drain connection where molded drain tube was removed.

(d.)Use inducer housing drain extension tube (violet label and factory-supplied in loose parts bag) to connect LOWER inducer housing drain connec- tion to condensate trap.

(e.)Determine appropriate length, cut, and connect tube to condensate trap.

(f.)Clamp tube to prevent any condensate leakage.

3.Relief Port Tube

Refer to Pressure Switch Tubing section for recommenda- tions and procedures.

Condenste Trap Field Drain Attachment

Refer to Condensate Drain section for recommendations and procedures.

Pressure Switch Tubing

One collector box pressure tube (pink label) is factory connected to the pressure switch for use when furnace is installed in UPFLOW or HORIZONTAL LEFT applications. This tube MUST be disconnected and used for the condensate trap relief port tube. The other collector box pressure tube (green label) which was factory connected to the condensate trap relief port connection MUST be connect to the pressure switch in DOWNFLOW or HORIZONTAL RIGHT applications.
