with local building codes.
6. Install a length of 3” (75 mm)
or 4” (100 mm) vent pipe into
the wall thimble. The pipe
should install easily into the
thimble.
7. Connect the exhaust vent
pipe to the exhaust pipe on
the stove. Seal the connection
with high temperature
silicone.
8. Push the stove straight back,
leaving a minimum of 4” (10
cm) clearance from the back
of the stove to the wall. Seal
the vent pipe to the thimble
with high temperature
silicone.
9. 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.
10. 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.
• 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.

:
A 45° elbow with a rodent screen may be used in place of the termination cap (or stainless steel
termination hood).
Figure 12 is the recommended installation set up.
Figure 13 is the installation to use if there is a concrete or retaining wall in line with exhaust vent on
a pellet stove. The termination must be 12” (30 cm) from the outside wall and 12” (30 cm) above the
ground.
