ZERO-CLEARANCE FIREPLACE
INSTALLATIONS
1. Manufacturer’s Instructions:
Carefully
read and comply with the manufacturer’s
installation instructions for your fireplace. Be
sure that DuraTech is approved for use with
your appliance.
2. Anchor Plate:
Attach an Anchor Plate
to the fireplace top with (4) 5/8” sheet metal
screws
(Fig 31)
. Check with the appliance
manufacture about the use of high temperature
sealants.
3. Chimney Sections:
Attach a Chimney
Section to the Anchor Plate by twist-locking
clockwise.
4. Completion:
Install the remainder of the
chimney as instructed for a standard Ceiling-
Supported installation, (using a Firestop
Radiation Shield in the 1st floor ceiling instead
of the Support Box). Always maintain at least
2 inches of clearance to combustibles, and
enclose the chimney where it passes through
occupied areas.
CONNECTION FROM APPLIANCE
TO CHIMNEY SYSTEM
1. Single Wall Stovepipe:
If single wall stovepipe
is desired, DuraVent’s “DuraBlack” single-wall
stovepipe is recommended. The connection
to the Ceiling Support Box, or Finishing Collar
is made with a DuraBlack Slip Connector or a
Snap-Lock Adapter. The beaded end of the Slip
Connector or Snap Lock Adapter slips into the
opening in the Ceiling Support or Finishing Collar.
Align the tabs on the Slip Connector or Snap
Lock Adapter with the notches in the face of the
Support Box or Finishing Collar, push it in and
rotate to lock it in place. Further instructions for
assembling DuraBlack Stovepipe are contained in
their shipping cartons. Remember, the minimum
clearance to combustibles for single wall stovepipe
is 18 inches.
2. Close Clearance Connector Pipe (DVL):
DuraVent manufactures a close clearance
connector pipe, also referred to as “DVL”. DVL
may be positioned as close as 6 inches to a
combustible wall, and as close as 8 inches to
a combustible ceiling, provided the appliance
installation instructions permit this distance. In
order to join this type of connector to the Support
Box or Finishing Collar, a DVL/DuraBlack Chimney
Adapter is required. The DVL/DuraBlack Chimney
Adapter slips into the opening in the Support Box
