OOF VENT INSTALLATION
If your vent is 8 ft. long or less, you can use a flexible vent 4"
x7" x 8 ft long centered by internal support to prevent 4"
central exit vent from touching the 7" inlet vent.
If the vent is longer than 8 ft. it must be rigid 4" x 6-7/8". This
fireplace is not approved for a longer flexible vent.
Start by determining where the outlet will be on the roof, and
cut an opening that fits the fireguard used. Be careful: the
opening on the roof will be oval due to the angle of the roof.
Build an interior frame 9 x 12.5 in. for a 45° slope) around
the opening to allow a minimum clearance of 1 in. from
combustible materials. It is best to set the opening between
the beams to minimize the work.
In attics, you may use an insulating shield for attic as well as
an insulating sleeve. However, use of the fireguard is
required when the vent goes through combustible materials.
For a vertical vent outlet, you must cut roof covering on a radius of 18 inches around the opening. Then
fix the roof support to the roof with screws provided for this purpose. (Figure 3.2.3.8.c)
