UNIT CORROSION HAZARD

Excessive exposure to contaminated combustion air may result

in safety and performance related problems.

Combustion air must not be taken from inside structure

because inside air is frequently contaminated by halogens,

which include fluorides, chlorides, bromides, and iodides.

These elements are found in aerosols, detergents, bleaches,

cleaning solvents, salts, air fresheners, adhesives, paint, and

other household products. Locate combustion-air inlet as far as

possible from swimming pool and swimming pool pump

house.

CAUTION

NOTE: All pipe joints must have cemented attachment of

combustion-air inlet pipe to inlet housing connection, since it

may be necessary to remove pipe for servicing.

Assembly of Combustion Air Pipe (Non-Direct Vent/1-Pipe

System ONLY)

1. Permanently install perforated disk assembly

(factory-supplied in loose parts bag) in combustion-air

elbow using RTV or by cementing, as shown in Fig. 39.

For 120,000 Btuh size units only: separate the 2 halves of

perforated disk assembly and use only the shouldered

disk half.

2. Determine the length of straight portion of combustion-air

inlet pipe from Fig. 39.

3. Cut field-supplied 2-in. (51 mm) diameter PVC pipe to

length as determined per Fig. 39.

4. Permanently attach elbow/perforated disk assembly to

straight portion of pipe using RTV or by cementing as

shown in Fig. 39.

Assembly of Combustion Air Pipe (Direct Vent-2-Pipe

System ONLY)

1. Using Table 13, determine the smallest combustion air

diameter permitted. Pick the larger diameter and use it for

both combustion and vent pipe.

NOTE: Do not count elbows or pipe sections in terminations or

within furnace (All elbows shown in Fig. 44 and Fig. 45 are not

to be counted).

UNIT MAY NOT OPERATE

Failure to follow this caution may result in incomplete

combustion, flame disturbance, or flame sense lockout.

When installing combustion air and vent system of short pipe

length, the smallest allowable pipe diameter must be used.

CAUTION

NOTE: A 2-in. (51 mm) diameter pipe must be used within

furnace casing. Make all pipe diameter transitions outside furnace

casing per Fig. 41.

2. If required per Table 13, insert perforated disk assembly

(factory-supplied in loose parts bag) in intake housing

where combustion air pipe will be connected. If half disk

set is required, install only shouldered disk half.
