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 Termination, 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 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.
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 fasteners
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 over the
vent pipe.
6. Slide the appliance and vent assembly
towards the wall carefully inserting the
vent pipe into the vent cap assembly. It is
important 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.
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.

DURA-VENT VERTICAL
TERMINATIONS
1. M a i n t a i n t h e 1 - 1 / 4 "
clearances (air spaces)
to combustibles when
passing through ceilings,
walls, roofs, enclosures,
attic rafter, or other nearby
combustible surfaces. Do
not pack air spaces with
insulation. Check the "Rigid
Pipe Venting Arrangments"
section 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
Thimble 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.
