VERTICAL INSTALLATION INSTRUCTIONS (CONT.)

INSTALLATION INTO AN EXISTING MASONRY CHIMNEY (USA ONLY)

Step 1. Before cutting any holes, assemble the desired sections of direct vent pipe to determine the center of the masonry penetration.

Step 2. Once the center point of the penetra-	FIG. 22
tion has been determined, cut a 6"
(152mm) diameter hole in the masonry.
If the hole is too large, the retro connec-
tor might not mount properly; if the hole
is too small, the appliance might starve
for intake air. If there is a frame wall in
front of the masonry wall, cut and frame
a 10" (254mm) square opening in the
wall (centered around the 6" [152mm]
masonry opening). If there is sheet rock
only (no studs) in front of the masonry
the 10" (254mm) opening is still needed,
but does not need to be framed. This
allows the retro connector to mount di-
rectly on the masonry and provide the
correct clearances to combustibles (see
Figure 22).

Step 3. Secure the flashing (SDV #705C) to the top of the masonry chimney using a bead of non-hardening sealant-adhe- sive. If the flashing is larger than the top of the chimney, cut and fold flashing as needed to fit chimney (Figure 23).

Step 4. To determine the length of flex needed, measure from 3" (76mm) above the top of the flashing down to the level of the opening. Add the distance from the cen- ter of the chimney out through the wall. Cut a piece of 4" (102mm) flex to this length (extended to its nominal length). Be sure to leave 2"-3" (51mm-76mm) of flex above the existing chimney to allow for connection to the termination kit.
