Combustion and Ventilation Air
WARNING: This appliance needs
fresh air for safe operation and must
be installed with provisions for ad-
equate combustion and ventilation
air available to the room in which it
is to be operating.
Follow CAN/CGA B149 (in Canada) or ANSI Z223.1
(in the USA) requirements, and any local codes or

VENTING
This appliance is designed to attach to a 4" diam-
eter type B-Vent or listed gas fuel type vent liner
running the full length of the chimney. A minimum
fl ue height of 12 feet is recommended. B-Vent
must be supported by a vent support - supplied
by vent manufacturer. See chart on this page
for minimum distances from roof.
The Regency Insert incorporates its own internal
draft hood, so no additional external draft hood
is required.
DRAFT HOOD
CONNECTION
1) Attach the vent to the fl ue collar on the detach-
able draft hood. The fl ue collar of the appliance
will fi t inside a standard vent and may be fas-
tened directly to the vent by sheet metal screw.
Diagram 1.
2) Before pushing the appliance into position
inside the fi replace, align the draft hood with
the guides on the insert top and pull forward.
While pushing the unit back into place, keep
pulling the draft hood forward until the screw
hole in the spill tube aligns with the screw hole
in the draft hood locking tab on the underside
of fi rebox top. The screw is secured through the
draft hood locking tab into the front of the spill
tube. (If screw holes do not line up then draft
hood is not positioned correctly.
Periodically check that the vent is unrestricted and
an adequate draft is present when the unit is in
operation. (See page 8 for spillage test.)
Before installing vent system ensure that the damper
plate is open and secure to prevent the damper plate
from falling down and crushing the liner.
