• 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.
Installation

9. Push the stove straight
back, leaving a minimum
of 100mm (4”) clearance
from the back of the
stove to the wall. Seal the
vent pipe to the thimble
with high temperature
silicone.
10. The pipe must extend at
least 30 cm (12”) away
from the building. If
necessary, bring another
length of pipe 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 91 to 152 cm (3 to 5 feet) of vertical
pipe outside the building to help naturally draft in the unit.
