WALL TERMINATION VENTING
Exterior wall opening:
Determine the exact position of the fi replace so that the vent pipe is centred
(if possible) between two building framing members. Consult your local
building codes prior to proceeding. The vent kit will accommodate up to
a maximum wall thickness of 12 inches.
1) Having determined the position of the fi replace, cut and frame a 14-
1/2 inch opening centred at a minimum height of 61 inches above the
fl oor. The opening may be round or square. Height of the opening will
vary with each installation. As the horizontal vent run increases, so
does the minimum vertical rise (see Fig. # 39).
IMPORTANT: When locating the opening, it should be noted that
vent terminal clearances must be maintained. See "Vent Terminal
Clearances" section for proper clearances.
A minimum 1 foot length of pipe is required for any wall termination. With
this minimal vertical rise in combination with a 90° elbow, a maximum
horizontal run of 24 inches is permitted. For longer horizontal runs greater
than 18 inches, increase vertical rise appropriately. The rise and run
must be constrained to the boundaries of the chart shown in fi g. # 39.
The horizontal run of vent should have a 1/4" rise for every 1 ft. of run
towards the termination.
Wall thimble:
Where a vent pipe passes through a combustible wall, a wall thimble/shield
must be used to retain insulation and maintain proper clearances. The wall
thimble may be cut to length for various wall thicknesses up to 12" thick.
Measure the wall thickness including the siding. Trim the shield to match
the wall thickness. Position the wall thimble from inside through the 14-
1/2" opening. Properly trimmed, the thimble should be fl ush with the outer
wall surface.
