INSTALLATION INSTRUCTIONS FOR THE
STANDARD HORIZONTAL TERMINATION
MINIMUM VENTING KIT
1. Install the 24” straight section on top of the vent
connector.
2. Place the 90-degree elbow on the 24” section. Facing
the direction expected to penetrate the wall.
3. Attach the 12” straight section to the 90-degree elbow.
Move the stove and pipe assembly backwards until the
12” straight is flush against the wall. Pull up on the
pipe to ensure that there is a ¼” per foot rise coming
out of the stove to the wall.
4. Draw a circle around the pipe. Use the center of this
circle as the center point of the 10” x 10” square wall
pass through. Cut and frame the wall pass through
opening.
5. Place the interior wall thimble into the 10” x 10” wall
pass through. Secure it with 4 screws (not provided).
Install the exterior portion of the thimble in similar
fashion, overlapping the 2 sections.
Caution: For buildings with vinyl siding, install a
vinyl siding standoff between the vent cap and the
exterior wall.
6. Install the horizontal vent termination on the outside of
the wall. Ensure both of the retaining straps extend
through interior wall thimble. Before attaching the vent
termination to the outside of the house, run a bead of
non-hardening mastic around its’ outside edges to
ensure a good seal between it and the wall. Ensure
the arrow on the end cap points up. Secure the cap
to the wall with appropriate screws.
7. Move the stove and vent pipe into position. Make sure
the 12” vent pipe extends into the horizontal vent cap a
minimum of 1-1/4”. Secure the vent using the straps
from the horizontal vent termination to the interior 6”
pipe with 2 sheet metal screws, keeping the screws as
close to the wall thimble as possible. Bend or cut any
excess strapping, so that it is not visible after the
installation is complete.
