Vent Termination Below Grade
Install Snorkel Kit #7FSDVSKS when it is not possible
to meet the required vent termination clearances of 12”
(305mm) above grade level. The snorkel kit will allow
installation depth of down to 7” (178mm) below grade
level. The seven inches is measured from the center of
the horizontal vent pipe as it penetrates the wall. If the
venting system is installed below grade, a window
well must be installed with adequate and proper
drainage. (Fig. 28)
NOTE: Be sure to maintain side wall clearances and
vent run restrictions. Refer to Figures 5, 6, 7, and 8.
1. Establish the vent hole through the wall.
2. Remove soil to a depth of approximately 16”
(400mm) below the base of the snorkel. Install a
window well (not supplied). Refill the hole with 12”
(305mm) of coarse gravel and maintain a clearance
of at least 4” (100mm) below the snorkel. (Fig. 32)
3. Install the vent system as described on Pages 14-17.
4. Be sure to make a watertight joint around the vent
pipe joint at the inside and outside wall joints.
5. Apply high temperature sealant around the inner
and outer snorkel collars. Join the pipes and fasten
the snorkel termination to the wall with the screws
provided.
6. Level the soil to maintain a 4” clearance below the
snorkel.
If the foundation is recessed, use extension brackets
(not supplied) to fasten the lower portion of the snor-
kel. Fasten the brackets to the wall first, and then
fasten to the snorkel with self-tapping #8 x 1/2” sheet
metal screws. Extend the vent pipes out as far as the
protruding wall face. (Fig. 29)

Vertical (Through the Roof)
Vent Assembly
Note that all vertically terminated installations must
include the restrictor plate included with the stove.
Refer to Page 8, Figure 8.
Make certain the vent system conforms to all other
requirements for vertical termination as specified on
Page 8.
This installation will require you to first determine the
roof pitch and use the appropriate vent components.
Refer to Pages 8 and 10, Figures 8 and 9.
1. Locate the final position of the stove, observing all
clearances for both the vent and the stove.
2. Plumb to the center of the inner (4”) flue collar from
the ceiling above, and mark that location.
3. Cut the opening:
CFM System: 9³⁄₈” x 9³⁄₈” (240 x 240mm)
DuraVent System: 10” x 10” (254 x 254mm)
4. Plumb any additional opening through the roof or
other construction that may be needed. In all cases,
the opening must provide a minimum of 1” (25mm)
clearance to the vent pipe.
5. Place the stove in its final position.
6. Install firestop(s) #7DVFS and Attic Insulation Shield
#7DVAIS as needed. (Fig. 30) If there is a room
above ceiling level, a firestop must be installed on
both the bottom and top sides of the ceiling joists.
If an attic is above ceiling level, an attic insulation
shield must be installed.
7. Install the appropriate roof support and flashing,
making certain that the upper flange of the flashing
base is below the shingles. (Fig. 31)
8. Install appropriate pipe sections until the vent run
reaches above the flashing. The enlarged ends of
the vent sections always face downward.
