DV Only: Maximum height allowed for the vent is 35ft
(10.67m).
Install sealed throat connector or flashing to prevent
leakage of room air up through chimney.
DV Only: Before installing vent liners, mark each liner on
both ends to designate which is the intake and the
exhaust.
Measure the height of the chimney beforehand and
purchase the appropriate kit. Never attempt to over-
stretch a flexible liner to accommodate the height of the
chimney.
The flue damper can be fully blocked open or removed for
installation of the Sienna; the smoke shelves, shields and
baffles may be removed if attached by mechanical
fasteners.
The chimney must be clean, in good working order and
constructed of non-combustible materials.
Make sure that all chimney cleanouts are tight fitting and
will not permit air to leak into the chimney.
Refractory, glass doors, screen rails, screen mesh and
log grates can be removed from the fireplace before
installing the Sienna.
