All PL Venting Components must be listed to UL 641 or ULC S609
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 accommodate
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.
2. ALL INTERLOCKING PIPE CONNECTIONS WITHIN THE ROOM MUST
BE SEALED WITH HIGH TEMPERATURE RTV AND SECURED WITH
A MINIMUM OF 3 FASTENERS PER CONNECTION.
Position the stove approximately 12” (305 mm) from the wall on the
fl oor pad. Push the “PL” pipe through the wall thimble. Squeeze a
bead of high temperature silicone (RTV) sealer around the end of the
machined portion of the 3” (76 mm) pipe connector on the back of
the stove. Firmly push on a section of “PL” pipe until inner pipe liner
pushes into the bead of RTV sealer.
3. Push the stove with pipe attached towards the wall (the pipe will go
through the wall thimble). Do not position the back of the stove closer
than 2” (51 mm) from the wall (see Clearances, Page 6).
4. Install listed type “PL” 45 degree elbow with rodent screen or cap 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.
5. If the installation includes a source of outside combustion air; cut a
separate hole through the wall for the fresh air tube. This tube should
be 1-5/8” (42 mm) [min.] diameter, steel only. Connect outside air pipe
to air inlet on stove. This tube must be terminated with a 90 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 specifi ed on this page
(see instruction #2). Install vent at clearances specifi ed by the vent
manufacturer.
• Greater back clearance will improve the ease of serviceability of the
stove.
• The end of the exhaust pipe must extend a minimum of 12” (305 mm)
from the outside of the building.
