Multi--venting and Vent Terminations

When 2 or more 355CAV Furnaces are vented near each other,

each furnace must be individually vented. NEVER common vent
or breach vent 355CAV furnaces.

CONDENSATE DRAIN

General

Condensate trap is shipped installed in the blower shelf and factory

connected for UPFLOW applications. Condensate trap must be
RELOCATED for use in DOWNFLOW and HORIZONTAL

applications.
Condensate trap MUST be used for all applications.
An external trap is not required when connecting the field drain to

this condensate trap.
The field drain connection (condensate trap or drain tube coupling)

is sized for 1/2--in. CPVC, 1/2--in. PVC, or 5/8--in. ID tube
connection.
Drain pipe and fittings must conform to ANSI standards and

ASTM D1785, D2466, or D2846. CPVC or PVC cement must
conform to ASTM D2564 or F493. Primer must conform to

ASTM F656. In Canada, use CSA or ULC certified schedule 40
CPVC or PVC drain pipe, fittings, and cement.
When a condensate pump is required, select a pump which is

approved for condensing furnace applications. To avoid
condensate spillage, select a pump with an overflow switch.
Furnace condensate is mildly acidic, typically in the pH range of
3.2 to 4.5. Due to corrosive nature of this condensate, a condensate

pH neutralizing filter may be desired. Check with local authorities
to determine if a pH neutralizer is required.

Application

The furnace, A/C, and humidifier drains may be combined and

drained together. The A/C drain must have an external,
field--supplied trap prior to the furnace drain connection. All drain

connections (furnace, A/C, or humidifier) must be terminated into
an open or vented drain as close to the respective equipment as

possible to to prevent siphoning of the equipment’s drain.

Fig. 46 -- Condensate Trap Heat Tape

See Fig. 45 for example of possible field drain attachment using
1/2--in. CPVC or PVC tee for vent and A/C or humidifier drain

connection.
Outdoor draining of the furnace is permissible if allowed by local

codes. Caution should be taken when freezing ambient may freeze

drain pipe and prohibit draining.

PERSONAL INJURY HAZARD
Failure to follow this warning could result in personal

injury or death.
Caution should be taken to prevent draining where slippery

conditions may cause personal injuries. Excessive

condensate draining may cause saturated soil conditions

which may result in damage to plants.

WARNING

Condensate Drain Protection

Freezing condensate left in condensate trap and drain line may

cause cracks, and possible water damage may occur. If freeze
protection is required, use condensate freeze protection accessory

or equivalent 3 to 6 watt per ft. (.3M) at 120v and 40_F (4.4_ C)
self--regulating, shielded, and waterproof heat tape. See Installation

Instructions supplied with accessory or heat tape manufacturer’s

recommendations.

1. Fold heat tape in half and wrap on itself 3 times.
