Lennox Traditions Freestanding P11 Installation Instructions Manual page 19

Installing Your Freestanding Pellet Stove
STANDARD HORIZONTAL EXHAUST INSTALLATION
1. Locate the proper position for the listed type "L" wall thimble. Avoid cutting wall studs when installing
your pipe. Use a saber saw or key hole 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 WITHIN THE ROOM MUST BE SEALED
WITH 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 "L" pipe
through wall thimble. Squeeze a bead of high temperature silicone (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 "L" pipe until inner pipe liner pushes into the bead of 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 1" (25mm) from the wall.
Note:
Greater back clearance will improve the serviceability of the stove.
4. Install listed type "L" 45 degree elbow with rodent screen or cap (optional) on outside end of pipe. The
rodent screen should be no less than 1/2" (13mm) 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 building.
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" (42mm) [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.
AIR MAY ALSO BE DRAWN FROM A VENTED CRAWL SPACE UNDER THE HOME. ALL JOINTS FOR
NOTE:
CONNECTOR PIPE SHALL BE REQUIRED TO BE FASTENED WITH AT LEAST THREE SCREWS. IF VENTED HORI­
ZONTALLY, JOINTS SHALL BE MADE GAST/GHT IN A MANNER AS SPECIFIED ABOVE. INSTALL VENT AT
CLEARANCES SPECIFIED BY THE VENT MANUFACTURER.
