Existing masonry chimney
ENG
(See figure 6/e)
FR
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
24
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 fla-
shing so that rain cap may be installed
and to allow for any adjustment to line
up base tee properly.
3. Fasten flashing to chimney top using
caulking and/or screws. If the top clay
tile is still in place, the corners of the fla-
shing 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 PROCE-
DURE (figure 6).
6. The remainder of the horizontal installa-
tion to the appliance can be done the
same as for side wall venting on page 22
observing rules for HORIZONTAL VEN-
TING.
7. Final adjustment may be made to the
top support if necessary.
