Apply high temperature sealant to 4” (102 mm) and
7” (179 mm) collars or the termination one inch away
from crimped end. Guide the vent terminations 4” and
7” collars into their respective vent pipes. Double check
that the vent pipes overlap the collars by 2” (51 mm).
Secure the termination to the wall with screws provided
and caulk around the wall plate to weatherproof. (Fig.

Support horizontal pipes every 3’ (914 mm)
with metal pipe straps.
Check fireplace to make sure it is leveled
and properly positioned.
Below Grade Installations
When it is not possible to meet the required vent ter-
minal clearances of 12” (305 mm) above grade level a
snorkel vent kit is recommended. It allows installation
depth of down to 7” (178 mm) below grade level. The
7” is measured from the center of the horizontal vent
pipe as it penetrates through the wall.
If venting system is installed below
ground, we recommend a window well with
adequate and proper drainage.
Ensure sidewall venting clearances are
observed.
If installing a snorkel, a minimum 24” (610 mm) vertical
rise is necessary. The maximum horizontal run with
the 24” (610 mm) vertical pipe is 36” (914 mm). This
measurement is taken from the collar of the fireplace (or
transition elbow) to the face of the exterior wall. Refer to
the Sidewall Vent Graph for extended horizontal run if
the vertical rise exceeds 24” (610 mm).
1. Establish vent hole through the wall. (Fig. 13)
2. Remove soil to a depth of approximately 16”
(406 mm) below base of snorkel. Install drain pipe.
Install window well (not supplied). Refill hole with 12”
(305 mm) of coarse gravel leaving a clearance of
approximately 4” (102 mm) below snorkel. (Fig. 20)
3. Install vent system.
4. Ensure a watertight seal is made around the vent
pipe coming through the wall.
5. Apply high temperature sealant caulking (supplied)
around the 4” and 7“ snorkel collars.
6. Slide the snorkel into the vent pipes and secure to
the wall.
7. Level the soil to maintain a 4” (102 mm) clearance
below snorkel. (Fig. 20)
