NSTALLATION
:
Vent installation: install vent at clearances specified by the vent manufacturer.
A chimney connector shall not pass through an attic or roof space, closet or similar concealed spaces,
or a floor, or ceiling. Where passage through a wall or partition of combustible construction is desired,
the installation must conform with all local regulations, including those referring to regional, national or
European Standards. Use 80mm stainless steel vent pipe to exhaust the unit to the outside.
1. Choose a location for your stove that meets the requirements stated in this manual and allows
installation with the least amount of interference to house framing, plumbing, wiring, etc.
2. Install a non-combustible hearth pad (where necessary).
3. Place the appliance 375 mm (15”) away from the wall. If the stove is to be set on a hearth pad, set
the unit on it.
4. Locate the center of the exhaust pipe on the stove. Extend that line to the wall. Once you have located
the center point on the wall, refer to pellet vent manufacturer installation instructions for correct hole
size and clearance to combustibles.
5. Install the wall thimble as per the instructions written on the thimble. Maintain an effective vapour
barrier in accordance with local building codes.
6. Install a length of 80mm (3”) vent pipe into the wall thimble. The pipe should install easily into the
thimble.
7. Install the fresh air intake (see O

).
8. Connect the exhaust vent pipe to the exhaust pipe on the stove. Seal the connection with high
temperature silicone.
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,
Figure 11: Straight through wall Installation.
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:
• It is recommended that horizontal through wall
installations have 3 to 5 feet (91 to 152 cm)
of vertical pipe in the system to help naturally
draft the unit in the event of extreme weather
or a power outage.
• 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 draft
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.
