• This is due to the back pressure in the exhaust 
caused by airflow around the structure.
•  All  sections  of  pipe  must  have  three  (3) 
screws  evenly  spaced  and  all  horizontal 
and vertical vent sections located within the 
house must have a bead of high temperature 
silicone installed on the male end of the pipe 
before installation to create a gas tight seal.
• The termination must be 12 inches (30 cm) 
from the outside wall and 12 inches (30 cm) 
above the ground.
• A  45° elbow  with  a rodent  screen may  be 
used  in  place of  the  termination  cap  (or 
stainless steel termination hood).

10. The  pipe  must 
extend  at  least 
12”  (30  cm)  away 
from  the  building. 
If  necessary,  bring 
another  length  of 
pipe (PL type) to the 
outside of the home 
to  connect  to  the 
first section. Do not 
forget to  place high 
temperature silicone 
around the pipe that 
passes  through  the 
thimble.
11. Install a vertical pipe, 
or if all requirements 
for  direct  venting 
are met, install vent 
termination.  The 
stainless  steel  cap 
termination  manufactured  by  the  vent  manufacturer  is  recommended.  However,  when  the  vent 
terminates several feet above ground level and there are no trees, plants, etc. within several feet, 
a  45° elbow  can  be used  as  termination. The  elbow  must be  turned  down to  prevent rain  from 
entering. 
NOTE:
• Some horizontal through wall installations may require a “T” and 3 to 5 feet (91 to 152 cm) of vertical 
pipe outside the building to help naturally draft in the unit. 
• This may be required if a proper burn cannot be maintained, after the stove has been tested and the 
airflow set.
