B. Visually inspect with a flashlight the
condition of the interior of the chimney
for cleanliness and structural integrity. All
evidence of soot and creosote must be
removed from the existing chimney system.
If you doubt your ability to accomplish this,
contact a certified chimney sweep. Do not
use chemical cleaners, as these can possibly
damage the inside of the chimney. Do any
required maintenance on the existing chimney
system at this time.
C. Install a DVL/DuraBlack Chimney Adapter -
product stock numbers (6”) 8674, (7”) 8774, or
(8”) 8874 - in the existing Ceiling Support Box.
Note that the DVL/DuraBlack Chimney Adapter
only connects to Dura-Vent chimney systems.
D. Connect the appropriate size Chimney
Adapter to the DVL/DuraBlack Chimney
Adapter.
E. Connect the appliance to the Chimney
Adapter using an Appliance Adapter, lengths
of pipe as required, and an Adjustable Length
pipe. Slide the Adjustable Length down over
the top pipe section, position the installation
vertically plumb, then slip the Adjustable
Length up and twist lock it to the Chimney
Adapter. Once all the components are firmly
seated and properly aligned, carefully drill
three 1/8” diameter holes through the outer
sleeve only in the center of the slots located
at the bottom of the Adjustable Length pipe.
Do not penetrate the inner liner. Use (3)
1/4” length sheet metal screws to secure the
Adjustable Length pipe.
