NOTE: A masonry chimney flue may be used
to route Z-VENT if no other appliance vents
directly into the same flue without a liner. Prior
to beginning the installation, be sure that the
existing chimney meets all national and local
building codes. The chimney must be cleaned,
removing all soot, debris and creosote before
installing Z-VENT.
1. Using the JOINT PROCEDURE, (figure 6)
join pipe lengths as they are lowered down
the chimney until bottom end lines up with
opening in chimney. (A rope may be used
to facilitate lowering of pipe).
2. Install flashing over last pipe length and
attach top support to pipe. Leave 6” (150
mm) of pipe protruding from flashing so
that rain cap may be installed and to allow
for any adjustment to line up base tee pro-
perly.
3. Fasten flashing to chimney top using
caulking and/or screws. If the top clay tile
is still in place, the corners of the flashing
must be notched and flashing plate formed
down around clay tile.
4. The rain cap may now be installed using
the JOINT PROCEDURE (figure 6).
5. Where required a drain tee should
be installed to a pipe as per JOINT
PROCEDURE (figure 6).
6. The remainder of the horizontal installation
to the appliance can be done the same as
for side wall venting on page 22 observing
rules for HORIZONTAL VENTING.
7. Final adjustment may be made to the top
support if necessary.
