The Vision Gas Fireplace must be vented vertically with a listed Type “B” gas vent that is nominally 8
inches in diameter. Any offsets must allow a minimum stack draft of -0.05” w.c. to be maintained.
The minimum vent run is 10 vertical feet from the flue outlet. Vertical runs as high as fifty feet are
in compliance. Minimum clearances to combustible materials from the vent are listed on the vent
pipe and must be maintained. The first piece of venting is a draft hood connector which is available
through your vent pipe supplier.
Trim the aluminum extension of the connector to 1 inch from the outer steel pipe as shown in Figure
12. Place the connector on the flue outlet so that the aluminum piece goes inside the flue outlet and
the steel piece goes outside.
Screw the two anchoring tabs to the draft hood connector as shown in Figure 13.
