STEP THREE: Using DuraVent's Masonry
Thimble with Slip Connector, connect slip
connector to Tee branch with the pre-
formed buttons. Slide Masonry thimble to
slip connector and attach black trim plate to
masonry surface using screws. (Fig.13)
for the Wall Pass-Through to fit through the
combustible wall. Again, before cutting this
hole, check the clearance from the top of the
Connector Pipe to the ceiling.
STEP TWO: If the minimum clearance to the
combustible ceiling is met, then drill a 3/8 inch
diameter hole through the combustible wall, at
the center of the 14-1/2 inch circle you have
inscribed. With a punch, mark the center on
the masonry behind the wall. Cut the 14-1/2
inch diameter hole in the wall. If it is necessary
to cut through studs, additional framing should
be installed to maintain the structural integrity
of the wall (Fig.14).

STEP FOUR:
Finish installation to appliance using connector
pipe, maintaining required clearances.
Combustible Wall and Masonry
(See completed installation in Fig.15)
STEP ONE: If no hole exists in the masonry,
mark the center point for the location of
penetration into the combustible wall. before
cutting or drilling, check the clearance between
the top of the connecting pipe to the ceiling,
as shown in Fig.12, Fig.15. The minimum
clearance to the ceiling for single wall pipe is
18", and for DuraVent DVL Connector Pipe, 8".
Scribe a circle from the center point on the wall
with a 7-1/4 inch radius (14-1/2 inch diameter)
(Fig.14). This is the size of the hole required
punched into the masonry, inscribe a circle
of 3- 1/4 inch radius (6-1/2 inch diameter),
or 4-1/4 inch radius (8-1/2 inch diameter),
depending upon whether 6 inch or 8 inch
Dura-Liner Pipe is used. Remove bricks as
necessary to approximate a circle. Smooth
out the circumference of the hole with high-
temperature grout or mortar. Maintain the
concentricity of this hole with the hole cut in
the combustible wall. The completed hole
should look like (Fig.14).
