PRODUCT INFORMATION, INSTALLATION AND MAINTENANCE
a
This Installation may cause problems during adverse
weather or power failure.
We strongly recommend using a battery backup system
■ ■
if the stove is installed using horizontal venting only.
This prevents any smoke from entering your home in
the event of a power failure.
a
Certain local code restrictions may apply. Check with
Local Officials first before installing.
Strictly observe the PL Vent manufacturer's safety spec-
■ ■
ifications when using wall pass through.
INSTALL EXHAUST VENT AT CLEARANCES SPECIFIED BY
■ ■
THE 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.
Do not place joints within wall pass-throughs.
■ ■
Ensure that all installation work is carried out to profes-
■ ■
sional standards.

4.10 VENTING: TERMINATION REQUIREMENTS

In determining optimum vent termination, carefully evaluate ex-
ternal conditions especially when venting directly through a wall.
Since you must deal with odors, gases, and fly ash, consider aes-
thetics, prevailing winds, distances from air inlets and combusti-
bles, location of adjacent structures and any code requirements.
- There is no minimum clearance requirement between exhaust
terminal and fresh air inlet if the exhaust terminal is positioned
above the fresh air inlet.
- 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 fac-
tors 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.
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 determin-
ing the exact location of the venting termination in relation ship
to doors, window, cavities or air vents.
Without outside combustion air connected to the unit
For These types of installations please refer to the dimensions list-
ed in figure.
A = EXHAUST TERMINAL
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).
