VENTING:TERMINATION REQUIREMENTS
In determining optimum vent termination, carefully evaluate external
conditions especially when venting directly through a wall. Since you
must deal with odors, gases, and fly ash, consider aesthetics, prevailing
winds, distances from air inlets and combustibles, location of adjacent
structures and any code requirements.
•
Exhaust must terminate above combustion air inlet elevation.
•
Do not terminate vent in any enclosed or semi-enclosed area, (i.e.
Carports, garage, attic crawl space, etc.) or any location that can build
up a concentration offumes.

•
When setting into place flue caps you should consider wind factors
such as dominate wind directions and currents in order to avoid down
draft, fly ash and/or smoke.
-
Vent surfaces can get hot enough to cause burns if touched
bychildren.
Non-combustible shielding or guards may be required.
-
Be sure to use approved pellet vent pipe and wall pass-
through fittings to go through combustible materials.
The type of installation must first be considered before determining
the exact location of the venting termination in relation ship to doors,
window, cavities or air vents. See figures 18-19.
Without outside combustion air connected to the unit.
For These types of installations please refer to the dimensions listed in
figure 18.
The clearance to a door, window or cavity must be at least:
- 4’ (1.2 m) below;
- 4’ (1.2 m) horizontally;
- 1’ (305 mm) above.
The clearance to fresh air intake for combustion of the pellet stove
or any other appliance, or the non-mechanical air supply inlet to the
buildingmust beat least 4’(1.2m).
The clearance to a mechanical air supply inlet to the building must be
at least 10’ (3 m).
With outside combustion air connected to the unit.
For These types of installations please refer to the dimensions listed in
figure 19.
