(b) Not less than 4 ft. (1.2m) below, 4 ft. (1.2m)
horizontally from or 1 ft. (305mm) above
any door, window or gravity air inlet into any
building.
(c) Not less than 2 ft. (0.61m) from an adjacent
building and not less than 7 ft.
(2.1m) above grade when located adjacent to
public walkways.
If it is desired to attach to an existing 6”, 7”
or 8” DuraTech, DuraPlus or DuraChimney
chimney, either roof supported, or ceiling
supported: (Figure 7).
A. Remove any existing connector pipe,
adapter or connector going into the ceiling
support box.
B. Visually inspect with a ashlight 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 certied
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, as shown in Figure 7. Note that the DVL/
DuraBlack Chimney Adapter only connects to
DuraVent chimney systems.
D. Connect the appropriate size Chimney
Adapter to the DVL/DuraBlack Chimney
Adapter.
E. Connect the appliance to the Chimney
Adapter using a Pipe 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 rmly 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) 3/8” length sheet metal
screws to secure the Adjustable Length pipe.
The completed installation will look like Figure
7.
Have the masonry chimney inspected
by a certied chimney sweep or installer, to
determine it’s structural condition.
