VENTING REQUIREMENTS
It is recommended that only an authorized dealer install
your pellet stove. The specified installation requirements
must be followed to ensure conformity with both the
safety listing of the appliance and local building codes.
All clearances, installation instructions and precautions
specified by the vent manufacturer must be followed.
Selecting a Location (Freestanding Models) - Review
the appliance clearance requirements before installing
the venting system (see page 6). Position the appliance
far enough away from walls to allow adequate room for
servicing. Choose the appliance location with the least
amount of interference with the house framing, plumbing,
wiring, etc.
Preferred Vent Configuration - For the best perform-
ance, we recommend a vent run design which runs verti-
cally and terminates above the roofline. This design will
allow natural draft to improve the flow of flue gases and
will aid in combustion and stove performance.
Type of Pipe - This stove requires type “PL” vent pipe
(pellet vent pipe, sometimes referred to as “L-Vent pellet
vent”), listed to UL 641 or ULC S609. Connect the pellet
vent pipe or the “tee” to the flue collar using a minimum
of three screws and seal as specified in “Pipe / Liner
Joint Requirements” on this page. Do not use class B gas
chimney or single wall chimney as a substitute.
Size of Pipe - These pellet appliances are approved for
use with the following vent sizes: 3” (75mm) standard, or
4” (100mm), see page 15 - for determining correct size
vent). When 4” pipe is used: for horizontal vent installa-
tions use a 3” (75mm) to 4” (100mm) adapter - available
from vent manufacturer. For vertical installations use a
3” (75mm) to 4” (100mm) “tee” - available from vent
manufacturer.
Note: If installation requires in excess of 11 feet (3 1/3
meter) of pipe, it is recommended that 4” (100 mm) pipe
be used.
Offsets - In every installation, a single or double clean-
out “tee” is recommended for every ninety-degree offset
(this tee will help collect ash residue and will allow for
routine cleaning without the need to disconnect sections
of pipe). Note: Offsets and horizontal runs accumulate
fly ash and soot which reduces the exhaust flow and per-
formance of the stove.
Total Offsets in venting system should not exceed 270°
total in direction change.
Horizontal Runs - The maximum total horizontal run
must not exceed 10 feet (3.1 meters).
Horizontal run of pipe requires 1/4” (7 mm) rise per foot.
Pipe Clearances / Requirements - See pipe manufac-
turers instructions for installation of venting components
and clearances. Follow pipe manufacturers installation
precautions for passing pipe through a combustible wall
or ceiling (i.e. use an approved thimble). Note: Pellet
vent pipe requires 3” (75mm) clearance from outside of
pipe unless otherwise specified by vent manufacturer -
all diameters: 3” (75mm) and 4” (100mm). A support
bracket must be installed every 4’ (1.2m) of pellet vent
pipe on the exterior wall of the house unless otherwise
specified by vent manufacturer.
Pipe / Liner Joint Requirements - All pipe joints must
be secured with a minimum of 3 screws. ALL horizontal
joints must be sealed gas tight (air tight, sealed connec-
tion). Use RTV high temperature silicone or Interam to
provide a complete seal at the flue collar and on all
joints.
Connection to Masonry Chimney through a Wall
(Freestanding Models) - Be sure to verify the construc-
tion of a masonry chimney, as it may have combustible
framing.
Approved liner when relining Masonry or Factory
Built Fireplaces is 2100HT (degree F.) liner listed to
UL 1777 or ULC S635.
Connection to an Existing Class A Chimney (Free-
standing Models) - A chimney adapter can be used to
make the connection from 3” (75mm) or 4” (100mm) pel-
let vent pipe (listed to UL 641 or ULC S609) to existing
UL chimney system. Verify with the pipe manufacturer
that your pipe brands will interconnect.
Horizontal-Vent Installations - On all horizontal-vent
installations (short, horizontal runs with no vertical pipe);
care should be taken when choosing a location for termi-
nating the vent. It is not recommended to directly vent
the exhaust on the prevailing wind side of the house. It is
recommended that when an appliance is vented directly
through a wall, a minimum of 8’ (2.5m) of vertical pipe
should be installed to create some natural draft. This will
reduce the possibility of smoke or odor entering the
dwelling during appliance shutdown or loss of power.
