structure of the fireplace and chimney, and will

CHIMNEY CAPS:
Mesh type chimney caps must have
provision for regular cleaning, or the mesh
should be removed to eliminate the
potential of plugging.
CLEARANCE TO COMBUSTIBLES:
The fireplace should be inspected to make
sure that there is adequate clearance to
combustibles, both exposed combustibles
to the top, side, and front as well as
concealed combustibles, in the chimney
and mantle area. Your local inspector
should have information on whether older
fireplaces are of adequate construction.

keep the label inside the firebox to avoid any
damage.

Since the information given on the certification label
attached to the appliance always overrides the

important to refer to it to have a safe and compliant
installation. The model and the serial number can
also be found on the label.
It is recommended to note the insert serial number
on this manual. It will be needed to identify the
version of the appliance in the event replacement
parts or technical assistance is required. It is also
recommended to register the warranty online at

If the fireplace's draft control system is to remain in
the masonry fireplace, it must be locked open for
access of the chimney liner or removed entirely. If
you remove draft control system from the masonry
hearth, you will need to install the metal plate
(27009), supplied with the owner’s manual kit,
indicating that the masonry hearth has been
modified. It must be secured inside the masonry
hearth, in a visible place and easy to locate.
