Installation Of Side Wall Venting
1. Establish the minimum distance from the bottom of fireplace to centre
of vent. Cut a hole through the wall allowing for a 11” x 11” (inside
diameter) in combustible walls for wall thimble or an 8” diameter hole in
a non-combustible wall (See Figure 1-2-3).
2. Note clearance to combustible as stated
.
3. Select the approximate vent length, precise measurements are not
needed as your flex pipe can be expanded to twice its shipped length
for ease of installation.
4. To install wall thimble centre over 11” x 11” (inch) framing from both
sides of wall and secure. Route flex vent pipe through wall thimble
(See Figure 1).
5. Before joining pipes, apply a bead of high temperature sealant (Mill
Pac) to end of pipe. First attach the four inch (4”) flue pipe to the vent
termination with sealant, and secure with 4 screws provided. At this
time make sure the spacer springs are attached to the (4”) flex pipe as
required. Then attach the seven inch (7”) pipe by the same method.
6. Mount vent termination and seal to wall using caulking around the wall
thimble to weather proof. After installing the vent termination, double
check to make sure the pipe extends properly through wall thimble and
into vent termination.
7. Before joining pipes to fireplace flue, apply a bead of high temperature
sealant (Mill Pac) to end of pipe. First attach the four inch (4”) flue pipe
to fireplace with Mill Pac sealant to the flue pipe and secure with 4
screws provided. At this time verify that the spacer springs are
attached properly to the (4”) flex pipe as required. Then attach the
seven inch (7”) pipe by the same method.
8. Support horizontal pipes every two (2) feet (61 cm) with metal strap
bands. Re-check fireplace to make sure it is levelled and properly posi-
tioned and secured.
9. Support vertical pipes to maintain a minimum of 1” or greater clear-
ance to combustibles with metal strapping bands.
10. If finishing the outside wall with vinyl or wood siding it is recommended
that a Siding Shield be installed, Part Number ZDVSSLR.
Note: Wall Thimble cover combustible wall up to 11” thick.
Note: Venting termination must not be recessed into wall or siding.
