INSTALLING YOUR FREESTANDING PELLET STOVE 
Standard Horizontal Vent Installation 

 
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 accommo-
date 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 WITH-IN 

THE ROOM MUST BE SEALED WITH HIGH TEM-
PERATURE RTV AND SECURED WITH A MINIMUM 
OF 3 FASTENERS PER CONNECTION. Position the 
stove approximately 12” (305 mm) from the wall on 
the floor 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” (76mm) pipe connector on the back of the 
stove. Firmly push on a section of  “PL” pipe until in-
ner 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” (51mm) 
from the wall (see clearances, page 6). Note: 
Greater back wall clearance will improve the ease of 
serviceability 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” (305 mm) from the outside of the 
building. 

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 sectional 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 #2). 
Install vent at clearances specified by the vent manufac-
turer.
