Horizontal Venting Requirements
Follow these guidelines if any part of the installation
incorporates a horizontal run or terminates horizontally.
• The maximum horizontal run made directly off the
rear of the stove shall be no more than 12" and must
then be connected to a 14" snorkel cap (Simpson Dura-
vent #982).
• The horizontal termination cap must maintain a 3"
clearance to any overhead combustible projections
exceeding 2 1/2" or less. Maintain 12" clearance from
projections exceeding 2 1/2". See Figure 8, page for
complete termination clearance information.
• Any horizontal run of vent must be level or have a 1/
4" rise for every foot of run toward the termination
cap.
NEVER ALLOW THE VENTING TO SLOPE DOWNWARD,
AS HIGH TEMPERATURES MAY RESULT AND CREATE A
HAZARDOUS CONDITION.
• Vent Pipe Clearance to Combustible Materials: For all
horizontal runs, a 2" top clearance and a 1" side and
bottom clearance must be maintained.
• Wall Pass-through: A minimum 10" X 10" square
cutout is required to maintain proper clearances
through combustible wall construction. The opening
must be framed in. Simpson Dura-Vent Wall Thimble
#942 or Secure Vent Wall Radiation Shield SV4RSM
must be used for the wall pass-through. Optional
decorative plates are available to finish the interior
side of the wall pass-through.
• IMPORTANT: Follow the vent manufacturer’s installa-
tion instructions provided with each vent component.
• DO NOT FILL AIR SPACE WITH ANY TYPE OF INSULATION.
• MAINTAIN THE PROPER CLEARANCES TO THE TERMI-
NATION CAP. SEE FIG. 10.
• Do not recess the termination cap into a wall or
siding.
• Install a Vinyl Siding Standoff between the vent cap
and the exterior wall (Simpson Dura-Vent #950). to
protect vinyl siding from overheating.
