NOTE: A 12-in. (304.8mm) minimum offset pipe section is recommended with short (5 to 8 ft) vent systems. This recommendation is to reduce excessive condensate droplets

NOTE: Starting at furnace, slope vent pipe a minimum of 1/4-in. (6.4mm) per linear ft back toward furnace with no sags between hangers.

VENT TERMINATION

General

Combustion-air (direct vent/2-pipe system only) and vent pipe must terminate outside structure, either through sidewall or roof. For vent termination clearance, refer to Fig. 34 for Direct Vent/2- Pipe system and Fig. 35 for Ventilated Combustion Air option.

Roof termination is preferred since it is less susceptible to damage or contamination, and it has less visible vent vapors. Sidewall termination require sealing or shielding of building surfaces with a corrosive resistance material due to corrosive combustion products of vent system.

NOTE: (Direct Vent/2-Pipe system ONLY) A factory accessory termination kit MUST be used. See section “Vent Termination Kit (Direct Vent/2-Pipe System Only)” in this instruction.

When determining appropriate location for termination, consider the following guidelines:

1.Comply with all clearance requirements stated in Fig. 34 or Fig. 35 per application.

2.Termination or termination kit should be positioned where vent vapors will not damage plants/shrubs or air conditioning equipment.

3.Termination or termination kit should be positioned so that it will not be affected by wind eddy, such as inside building corners, nor by recirculation of flue gases, airborne leaves, or light snow.

4.Termination or termination kit should be positioned where it will not be damaged by or subjected to foreign objects such as stones, balls, etc.

5.Termination or termination kit should be positioned where vent vapors are not objectionable.

Extended Exposed Sidewall Pipes

Sidewall combustion air pipe termination (direct vent/2-pipe system only) and vent pipe termination may be extended beyond area shown in Fig. 36 or in Fig. 37 per application in outside ambient by insulating pipe as indicated in Table 6.

1.Determine combustion air pipe diameter (direct vent/2-pipe system only) and vent pipe diameter, as stated above, using total pipe length and number of elbows.

2.Using winter design temperature (used in load calculations), find appropriate temperature for your application and furnace model.

3.Determine required insulation thickness for exposed pipe length(s).

NOTE: Pipe length(ft) specified for maximum pipe lengths located in unconditioned spaces cannot exceed total allowable pipe length as specified in Table 6.
