Minimum Venting Installation
Instructions
1. Install the 36" pipe section onto the starter collar
by fully inserting it and turning approximately ¼
turn clockwise, until the 2 sections are fully
locked. Install the 90º elbow in similar fashion.
2. Move the stove and pipe assembly back until the
90º elbow is flush to the wall. The 36" vertical
pipe should be parallel to the wall. 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.
3. 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.
4. 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, so
as to make a seal between it and the wall. The
arrow on the end cap should point up. Secure
the cap to the wall with the appropriate screws.
Place the thimble cover onto the 90º elbow. Put
the 9" pipe into the horizontal vent cap, (the vent
pipe must extend into the horizontal vent cap a
minimum of 1-1/4"). Move the stove and vent
pipe into position, insert the 9" pipe into the 90º
elbow and twist to lock it. Secure the straps from
the horizontal vent termination to the interior
pipe with 2 sheet metal screws, keeping the
screws as close to wall thimble as possible.
Bend or cut the excess strapping so that the
thimble cover will fit properly. Screw the thimble
cover to the wall.
