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 of fumes.
• Terminals must not to be recessed into a wall or siding.
• 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.
a
Vent surfaces can get hot enough to cause burns if touched
by children.
Non-combustible shielding or guards may be required.
a
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
building must be at least 4’ (1.2 m).
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.

This configuration will help prevent blockage of vent by snow drifts. Also the minimum vertical run of 5 feet (1.5 m) ensures the ventilation of the
exhaust in the event of a power failure, and allow for easier cleaning through cleanout on tee.
a
Certain local code restrictions may apply. Check with Local Officials first before installing.
a
Strictly observe the PL Vent manufacturer’s safety specifications when using wall pass through.
a
INSTALL VENT AT CLEARANCES SPECIFIED BY THE VENT MANUFACTURER.
a
Double wall PL vent requires a minimum clearance to combustibles according to the manufacturer’s safety specifications and the use
of listed wall thimble, fire stop or roof flashing where applicable.
a
Do not place joints within wall pass-throughs.
a
Ensure that all installation work is carried out to professional standards.
