Horizontal Venting (Horizontal Termination)
•
The maximum horizontal run made directly off
the rear of the stove into a standard horizontal
cap (#984 or #985) must be no more than a 9”
section of Simpson Dura-vent (#907B). See Figure
12-1.
•
The maximum horizontal run made directly off
the rear of the stove into a 14” snorkel cap (#982)
must be no more than a 24” section of Simpson
Dura-vent (#904). See Figure12-3.
• The horizontal termination cap must maintain a
3" clearance (80 mm) to any overhead combus-
tible projections 2 1/2" (60 mm) or less. Maintain
12" (300 mm) clearance from projections exceed-
ing 2 1/2". See Figure 13.
•
Any horizontal run of vent must be level or have a
1/4" (5 mm) rise for every foot (300 mm) of run
toward the termination cap. DO NOT ALLOW THE
VENT TO RUN DOWNWARD, AS THIS CAN CAUSE
HIGH TEMPERATURES AND THE POSSIBILITY OF A
FIRE.
• A 1” (26 mm) clearance must be maintained
around all co-axial vent pipe.
• For buildings with vinyl siding, a Vinyl Siding
Standoff should be installed between the vent
cap and the exterior wall (Simpson Dura-Vent
#950). The Standoff prevents exposure of the
vinyl siding to excessive heat that can damage
the siding material.
• A 10" X 10" (250 mm x 250 mm) square hole is
required to maintain proper vent clearances
through a combustible wall. Simpson Dura-Vent
Wall Thimble #942 installed according to the
manufacturer’s instructions meets clearance
requirements.
• DO NOT FILL AIR SPACE WITH ANY TYPE OF
INSULATION.
•
Do not recess the termination cap into the
exterior wall or siding.
