Horizontal Vent Installation
1. Use the Venting Table to determine the
minimum distance from the bottom of fireplace to
center of vent. Cut a hole through the wall
allowing for an 11” x 11” (inside diameter) in
combustible walls for wall thimble or an 8”
diameter hole in a non-combustible wall (See
Figure 3).
2. For the clearance to combustible above a 90
degree bend see
Clearance to Combustibles
section.
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 center over 11” x 11”
(inch) framing from both sides of wall and
secure. Route flex vent pipe through wall
thimble.
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 the four 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 sealant, and secure with the four 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 positioned and secured.
9. Support vertical pipes to maintain a minimum of 1” or greater clearance to combustibles with metal strapping bands.
If finishing the outside wall with vinyl or wood siding it is recommended that a Siding Shield be installed, Part Number ZDVSSLR.
