HORIZONTAL EXHAUST THROUGH THE WALL
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 15” (37.5 cm) 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, use a hole saw to cut a 7” (175 mm) diameter hole for a 3” (76 mm) vent pipe
or an 8” (200 mm) hole for a 4” (101 mm) vent pipe.
5. Install the wall thimble as per the instructions written on the thimble.
6. Install a length of 3” (76 mm) or 4” (101 mm) vent pipe into the wall thimble. The pipe should install easily
into the thimble.
7. Install the fresh air intake (SEE PAGE 23)
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 2” (5 cm) 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 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-degree elbow can be used as termination. The elbow must be turned down to prevent rain from
entering.
Note: Some horizontal, through the wall
installations may require a “T” and 4-5 feet (122 to
152 cm) of vertical pipe outside the building to help
the stove draft properly. 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
backpressure in the exhaust, caused by the airflow
around the house.
