Below Grade Installation
If the Snorkel Termination must be installed
below grade, i.e. basement application, proper
drainage must be provided to prevent water
from entering the Snorkel Termination. Refer to
Dia. 4. Do not attempt to enclose the Snorkel
within the wall, or any other type of enclosure.
Diagram 4
4) If installing the vent termination to a wall
with vinyl siding, the Vinyl Siding Standoff
must be used. Attach the Vinyl Siding
Standoff to the Horizontal Vent Termina-
tion, but first run a bead of non-hardening
mastic around its outside edges, so as to
make a seal between vent cap and the
standoff. Install the Vinyl Siding Standoff
(Part # 950) between the vent cap and the
exterior wall and attach with the four wood
screws provided. Seal around the Vinyl
Siding Standoff on all four sides. Diagram
5. The arrow on the vent cap should
be pointing up. Insure that the 1-1/4"
clearances to combustible materials are
maintained. See diagram 5.

Note:
If installing termination on a siding
covered wall, a vinyl siding standoff or
furring strips must be used to ensure that
the termination is not recessed into the
siding. The four wood screws provided
should be replaced with appropriate fas-
teners for stucco, brick, concrete, or other
types of sidings.
5) Before connecting the horizontal run of
vent pipe to the vent termination, slide the
black decorative wall thimble cover over
the vent pipe, then slide the Wall Thimble
(Part # 942) over the vent pipe.
6) Slide the appliance and vent assembly to-
wards the wall carefully inserting the vent
pipe into the vent cap assembly. It is impor-
tant that the vent pipe extends into the vent
cap a sufficient distance so as to result in
a minimum pipe overlap of 1-1/4 inches.
Secure the connection between the vent
pipe and the vent cap by attaching the two
sheet metal strips extending from the vent
cap assembly into the outer wall of the vent
pipe. Use the two sheet metal screws
provided to connect the strips to the pipe.
Bend any remaining portion of the sheet
metal strip back towards the vent cap, so
it will be concealed by the decorative wall
thimble cover. See diagram 6.

7) Install the Wall Thimble in the center of the
10" square and attach with wood screws.
8) Slide the decorative wall thimble up to the
wall surface being careful not to scratch
the paint and attach with screws provided.
Apply decorative brass or chrome trim if
desired. See diagram 7.

INSTALLATION
DURA-VENT VERTICAL
TERMINATION
1) Maintain the 1-1/4" clear-
ances (air spaces) to com-
bustibles when passing
through ceilings, walls,
roofs, enclosures, attic raft-
er, or other nearby com-
bustible surfaces. Do not
pack air spaces with insu-
lation. Check page 9 for the
maximum vertical rise of
the venting system and the
maximum horizontal offset
limitations.
2) Set the gas appliance in its
desired location. Drop a
plumb bob down from the
ceiling to the position of
the appliance flue exit, and
mark the location where
the vent will penetrate the
ceiling. Drill a small hole at
his point. Next, drop a
plumb bob from the roof to
the hole previously drilled in the ceiling, and
mark the spot where the vent will penetrate
the roof. Determine if ceiling joists, roof
rafters or other framing will obstruct the
venting system. You may wish to relocate
the appliance or to offset, as shown in
diagram 9 to avoid cutting load bearing
members.

3) To install the Round Support Box/Wall Thim-
ble in a flat ceiling, cut a 10 inch square hole
in the ceiling centred on the hole drilled in
Step 2. Frame the hole as shown in diagram
10.
