EXISTING MASONRY CHIMNEY
(see illustration #5)
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,
(illustration #1 & images 1, 2 & 3) 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 properly (
see image 10 ).
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
(illustration #1 images 1, 2 & 3) .
5. Where required a drain tee should be installed to a pipe as per JOINT PROCEDURE
(image 8 & 9) .
6. The remainder of the horizontal installation to the appliance can be done the same as for side wall venting illustration 2
observing rules for HORIZONTAL VENTING.
7. Final adjustment may be made to the top support if necessary.
