Installing the Vertical Vent Kit
The two identical flat, rectangular steel pieces
are designed to be installed inside the firebox
over the bottom edge of the fresh air intake
openings located at the back of the firebox. Use
the following method:
1) Access the firebox by following the
instructions on pages 9 and 10 of this
manual.
2) Remove the burner and carefully set
aside.
3) Remove the bottom center fresh air duct
screw from both the left and right side inlets.
4) Position the restrictor plates over the intake
openings by resting them on the firebox
bottom and sliding them left or right until the
screw hole in the restrictor plate aligns with
the screw hole in the firebox exposed by
removing the screw in step 3 above.
5) While holding the restrictor plate in position,
re-install the fresh air duct screws removed
in step 3 and tighten snugly.
6) Reverse steps 4-1 to reassemble stove.
When the total vertical vent run in
a particular Bristol installation
meets or exceeds 8’, the Vertical
Vent Kit must be installed in the
stove. This kit is shipped with
every stove and consists of the
three steel components shown
below (not shown to scale).
