INSTALLATION

INSTALLING YOUR FREESTANDING PELLET STOVE
Standard Horizontal Vent Installation
1. Locate the proper position for the listed type “PL”
wall thimble. Avoid cutting wall studs when installing
your pipe. Use a saber saw or keyhole saw to cut
the proper diameter hole through the wall to accom-
modate the wall thimble. Use extreme caution to
avoid cutting into power lines within the wall of the
home. The hole size will depend on the brand of
pellet vent that you are using. Install the wall thimble
in the hole.
ALL INTERLOCKING PIPE CONNECTIONS WITH-
IN THE ROOM MUST BE SEALED WITH High Tem-
perature RTV AND SECURED WITH A MINIMUM
OF 3 FASTENERS PER CONNECTION.
2. Position the stove approximately 12” (.3m) from the
wall on the floor pad. Push listed type “PL” pipe
through wall thimble. Squeeze a bead of high tem-
perature silicone (High Temperature RTV) sealer
around the end of the machined portion of the 3”
(76mm) pipe connector on the back of the stove.
Firmly push on a section of listed type “PL” pipe until
inner pipe liner pushes into the bead of High Tem-
perature RTV sealer.
3. Push the stove (with pipe attached) towards wall.
Pipe will go through the wall thimble. Do not position
the back of the stove closer than 2” (51mm) from the
wall.
NOTE: Greater back clearance will improve the ser-
viceability of the stove.
4. Install listed type “PL” 45 degree elbow with optional
rodent screen or cap (recommended) on outside end
of pipe. The rodent screen should be no less than
1/2” (13 mm) mesh and may clog with soot and ash
if left unattended during the burn season.
NOTE: The end of the exhaust pipe must extend a
minimum of 12” (.3m) from the outside of the build-
ing.
5. If the installation includes a source of outside com-
bustion air; cut a separate hole through the wall for
the fresh air tube. Use a galvanized or stainless
steel pipe for the duct. The minimum size for the
duct shall be not less than 50% of the cross sec-
tional flue area. Connect outside air pipe to air inlet
on stove. This tube must be terminated with a 45
degree elbow or hood.
NOTES:
Combustion air may also be drawn from a vented crawl
space under the home.
All joints for connector pipe are required to be fastened
with at least three screws. If vented horizontally, joints
shall be made gas-tight (air tight, sealed connection) in
a manner as specified on this page (see instruction #1).
Install vent at clearances specified by the vent manu-
facturer.
