B-Vent Metal Chimney Installation
1.
Mount Anchor Plate with down draft diverter: Chimneys
for Isokern BVETTO fireplaces begin with an Anchor Plate
with down draft diverter.
It is important that the surface of the Isokern chimney
has a level surface on which to attach the Anchor Plate. If
the top of the Isokern does not have a level surface, then
it will need to be modified accordingly.
Center the Inswool blanket over Isokern Top Plate
hole and trace outline of hole with a pen or marker. Cut
a hole in the blanket to match the hole in the Isokern
top plate. Center the Inswool blanket over the Isokern
Top Plate flue opening, then center anchor plate over the
Inswool blanket. Make sure nothing interferes with the
damper plate movement.
Secure the Anchor Plate with four (4) masonry
anchors.
(Figure 21)
If the Anchor Plate with Damper
is installed the damper should swing freely. When the
chain is pulled down, the damper should close (horizontal
position). When the chain is released (no weight on the
chain), the damper should swing open (vertical position).
To install the lintel hook, place the damper plate in
the closed (horizontal) position. Determine and mark
the position of the lintel hook. The lintel hook should be
mounted in a position so as to provide a small amount of
tension in the spring attached to the chain.
The tension is needed to prevent the damper plate
from rattling when closed. Mount the lintel hook to
masonry with the screws provided. Do not obstruct oval
openings in the anchor plate.
WARNING:
Do not locate Anchor Plate with Down Draft
Diverter in a location inaccessible for inspection, cleaning
and servicing after installation.
2.
Starting at the anchor plate, attach the first section of
B-Vent Pipe. It is acceptable to use screws to attach the
B-Vent to the anchor plate.
The B-Vent sections and components use the Metal-
Fab positive twist lock for interconnections. Align the
ends of the vent, push together then twist section to
lock in place.
(Figure 22)
No additional fasteners are required to assure a safe
installation. It is acceptable to apply screws at the joints
if local code requires, or at the installing contractor’s
option, provided that the screws
do not
penetrate the
flue.
NOTE:
When installing B-Vent always align “Up” arrow
away from appliance. Chimneys must be installed so that
access is provided for inspection and cleaning.
