Alternate Combustion Air Intake Location

NON-DIRECT VENT (SINGLE PIPE) PIPING

Non-direct vent installations require only a vent/flue pipe. The vent pipe can be run horizontally with an exit through the side of the building or run vertically with an exit through the roof of the building. The vent can also be run through an existing unused chimney; however, it must extend a minimum of 12 inches above the top of the chimney. The space between the vent pipe and the chimney must be closed with a weather-tight, corrosion-resistant flashing. For details concerning connection of the vent/flue pipe to the furnace, refer to Section IX, Vent/Flue Pipe and Combustion Air - Standard Furnace Connections or Alternate Furnace Con- nections for specific details. Refer to the following Non-Direct Vent (Single Pipe) Piping - Vent/Flue Pipe Terminations for spe- cific details on termination construction.

Although non-direct vent installations do not require a combus- tion air intake pipe, a minimum of one 90° elbow should be at- tached to the furnace’s combustion air intake if: an upright instal- lation uses the standard intake location, or a horizontal installa- tion uses the alternate air intake location. This elbow will guard against inadvertent blockage of the air intake.

VENT/FLUE PIPE LENGTHS AND DIAMETERS

Refer to the following table for applicable length, elbows, and pipe diameter for construction of the vent/flue pipe system of a non-direct vent installation. In addition to the vent/flue pipe, a single 90° elbow should be secured to the combustion air intake to prevent inadvertent blockage. The tee used in the vent/flue termination must be included when determining the number of elbows in the piping system.

(1)One 90° elbow should be secured to the combustion air intake con- nection.

(2)Minimum vent length is five feet and one elbow/tee.

(3)Tee used in the vent/flue termination must be included when determin- ing the number of elbows in the piping system.

(4)3” diameter pipe can be used in place of 2” diameter pipe.

VENT/FLUE PIPE TERMINATIONS

The vent/flue pipe may terminate vertically, as through a roof, or horizontally, as through an outside wall.

Vertical vent/flue pipe terminations should be as shown in the following figure. Refer to Section IX, Vent/Flue Pipe and Com- bustion Air Pipe - Termination Locations for details concerning location restrictions. The penetration of the vent through the roof must be sealed tight with proper flashing such as is used with a plastic plumbing vent.

Horizontal vent/flue pipe terminations should be as shown in the following figure. Refer to Section IX, Vent/Flue Pipe and Combus- tion Air Pipe - Termination Locations for details concerning loca- tion restrictions. A 2 3/8” diameter wall penetration is required for 2” diameter pipe while a 3 1/2” diameter hole is required for 3” diameter pipe. To secure the pipe passing through the wall and prohibit damage to piping connections, a coupling should be in- stalled on either side of the wall and solvent cemented to a length of pipe connecting the two couplings. The length of pipe should be the wall thickness plus the depth of the socket fittings to be installed on the inside and outside of the wall. The wall penetra- tion should be sealed with silicone caulking material.

In a basement installation, the vent/flue pipe can be run between joist spaces. If the vent pipe must go below a joist and then up into the last joist space to penetrate the header, two 45° elbows should be used to reach the header rather than two 90° elbows.
