• 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.
• This is due to the back pressure in the exhaust caused by airflow around the structure.
