NOTICE
Accessories for woodstoves for clearance reduction have
been developed by many manufacturers. If not following
the methods of the installation codes, be sure that any
accessory you choose has been tested by an independent
laboratory and carries the laboratorys testing mark.
Make sure to follow all of the manufacturers
instructions.
Always contact your local building inspector or fire
officials about restriction and requirements in your area.
Reminder, it is the local officials who have final authority
in the installations approval.
ALCOVE
The F 3 CB is approved for installations in an
unprotected and protected ALCOVE provided the
following guidelines are followed: Stoves must be
positioned as shown in figures 13 or 14.
MINIMUM UNPROTECTED ALCOVE:
Assumes-
top exit, single wall pipe, and stoves rear heatshield.
Minimum alcove width = 71
(1805mm)
Maximum alcove depth = 40 (1015mm)
Height above the top of the stove = 68 (1730mm)
Top vent/vertical- assumes the connector pipe is
exiting off the top of the stove and traveling vertically.
If top vented to any horizontal runs the stoves
position is dictated by the connector pipe clearances.
MINIMUM PROTECTED ALCOVE:
Assumes-
top exit, double wall pipe, and stoves rear heatshield.
Minimum alcove width = 35
(890mm)
Maximum alcove depth = 24 (610mm)
Height above the top of the stove = 40 (1015mm)
In a PROTECTED alcove installation both side walls
and rear wall must be protected per NFPA 211 or
CAN/CSA-B365. The wall protection must be
elevated 1 from the floor and at least 1 off the
combustible wall to allow for an air-flow.

REAR EXIT ALCOVE INSTALLATIONS:
Unprotected alcove: assumes single wall pipe and

Maximum alcove depth = 40 (1015mm)
Alcove ceiling above top of stove = 68 (1730mm)
Protected alcove: assumes double wall pipe and
stoves rear heatshield.
Minimum alcove width = 35 (890mm)
Maximum alcove depth = 30 (760mm)
Alcove ceiling above top of stove = 40 (1015mm)
