TERMINATION TYPES
The combustion air intake and exhaust vent system and
termination may be installed in one of the following type
terminations:
1. Horizontal (2 Pipe) (air intake and exhaust vent).
2. Vertical (2 Pipe) (air intake and exhaust vent)
3. Concentric (horizontal/side wall installation).
4. Concentric (vertical/roof installation).
5. Deluxe Horizontal Venting kit (2 Pipe) (air intake and
exhaust vent).
6. Low Profile (2 Pipe) (air intake and exhaust vent).
All pipe, fittings, pipe cement, primers and procedures
must conform to American National Standard Institute
and American Society for Testing and Materials (ANSI/
ASTM) standards.
SIDE WALL VENT TERMINATION (STANDARD)
Important:
When terminating the vent on a side wall, the
following specifications pertaining to terminal location must
be followed (see Figure 19).
1. The air intake terminal and the exhaust vent terminal
must terminate on the same exterior wall.
2. The vertical centerline of the air intake terminal
must be located at a minimum of 8” from the vertical
centerline of the exhaust vent terminal.
3. The horizontal centerline of the air intake terminal may
not be located more than 24” below the horizontal
centerline of the exhaust vent terminal.
4. To avoid exhaust recirculation, the air intake terminal
may be rotated away from the exhaust vent terminal
(see Figure 19).

1. The air intake termination and the exhaust vent
termination shall extend 12” above anticipated snow
level and at least 12” above the roof.
2. Must provide proper support for all pipes protruding
through roof.
3. The vertical roof terminations should be sealed with a
plumbing roof boot or equivalent flashing.
4. The air intake termination and the exhaust vent
termination must penetrate the same side of roof.
5. The centerline of the air intake termination and the
centerline of the exhaust vent termination must not
be closer than 8”.
6. The air intake terminal and the exhaust vent terminal
must be oriented facing downward and the same
direction.
