Chimney Installation - Morso 5660 Instalation Manual

Installing the Morsø 5660 Fireplace Insert Zero Clearance Enclosure
COMBUSTIBLE FRAMING
The Morsø 5660 Fireplace Insert Zero Clearance Enclosure is designed with spacers on the side
and back surfaces that prevent the enclosure walls from coming in contact with adjacent combusti-
ble materials that are used for framing around the enclosure. In addition, the top of the enclosure
includes a standoff that prohibits the header for the combustible construction above the enclosure
from being installed too close the heat from the Insert, enclosure top and chimney. Under no cir-
cumstances should the spacers or standoff be modified. REDUCTIONS TO ANY OF THE RE-
QUIRED CLEARANCES MAY RESULT IN PROPERTY DAMAGE, BODILY INJURY OR EVEN
DEATH.
Refer to the adjacent illustration for minimum clearance
requirements. Typical framing along with rough framing
dimensions are shown in FIGS. 2, 3 & 4 on page 7 of
these instructions. The actual framing details will vary de-
pending on the placement of your enclosure and insert. It
is important to take care when framing to be sure that the
area under the enclosure is level and that all framing
members are plumb. Forcing the enclosure into a open-
ing that is not level and plumb will cause problems later in
the installation process and should be avoided.
It is important to note that only nominal 2 X 4 framing ma-
terials should be used to frame the area directly above the
standoff on the front of the enclosure. This is necessary
to prevent combustible framing from encroaching in the
space above the enclosure top. We suggest that the
framing for the area directly above the standoff on the front of the enclosure be done after the enclo-
sure is secured in place and chimney has been installed. This allows room to work on the chimney
and for access for the building inspector.
Once the rough framing is completed, the Fireplace Insert Zero Clearance Enclosure (with chimney
base or anchor plate and flexible vent connector installed) can be slid into the rough opening. Make
any last adjustments to center the enclosure in the opening and secure in place with at least four
nails using the pilot holes provide in the enclosure front flanges. Countersink the nail heads until
they are flush with the front flange surfaces as this will facilitate installation of facing materials later.

CHIMNEY INSTALLATION

With the Fireplace Insert Zero Clearance Enclosure secured to the framing, the chimney system may
now be installed. Follow the chimney manufacturer's instructions exactly including the use of all
support hardware, elbows, joist, attic and insulation shields, firestops, flashing kits, storm collars and
caps. The safety and functionality of the chimney are critical parts of the installation of the enclosure
and Insert.
After the chimney installation is complete, install the framing above the standoff on the front of the
enclosure. This would be a good time to install the required non-combustible facing base material to
the front of the enclosure. See FIG. 6 on page 8 for information on the limits for placement of com-
bustible and non-combustible materials. We recommend that you wait to place any combustible fac-
ing materials on any framing until after the installation has been inspected and approved by your lo-
