SELECTING THE LOCATION FOR YOUR INSTALLATION
This insulated metal fireplace insert zero clearance enclosure enables the MORSØ MODEL 5660
STANDARD or MODEL 5660 NA Fireplace Insert to be installed in minimum–clearance situations in
locations without an existing masonry fireplace. This could be in new home construction or in
homes that are being remodeled.
Centrally located installations generally provide and circulate the heat most effectively. An interior
chimney is preferred as it will stay warmer and provide a more consistent draft than an exterior chim-
ney. However, many installation options are possible. If an exterior chimney is necessary for your
installation, it is recommended that exterior chimney be enclosed in a chase to minimize heat loss.
Installing the Morsø 5660 Fireplace Insert Zero Clearance Enclosure
The Model 90566000 or Model 90566400 Fireplace Insert Zero Clearance Enclosure may be ele-
vated off the floor to allow the Insert Model 5660 STANDARD or 5660NA to be placed higher
up on the wall. This will require construction of a base structure to support the enclosure and insert.
The base structure should meet the same structural requirements as any other floor construction
meeting building code requirements in your area since it is supporting and transferring the apprecia-
ble weight of the enclosure and the Insert to the floor below it. The surface of the base structure
should be covered with a minimum of one layer of ¾ plywood. The distance from the top of the sup-
port structure to the ceiling above Models 5660 STANDARD or 5660NA may be no less than
67” (1701mm). See FIG. 5 on page 8 for support structure information.
The face of the support structure should be covered with non-combustible materials only, all the way
to the floor.

CHIMNEY REQUIREMENTS
For proper draft and best performance, the chimney should extend at least 15’ (4.6m) and not more
than 35’ (10.6m) above the level of the MORSØ Model 5660 STANDARD or Model 5660NA hearth.
The chimney must be properly installed and supported in accordance with the chimney manufac-
turer’s instructions. The enclosure is not intended to support the entire weight of the chimney. Sup-
port components are available from the chimney manufacturer.
If possible, an installation with a straight vertical chimney will provide the best draft and will be easi-
est to clean.
If a straight chimney is not possible due to obstructions, up to four 30° elbows may be used to offset
the chimney around the obstructions. The elbows must be used in pairs in order to return the chim-
ney to vertical after passing the obstruction. The first offset must be at least 8’ (2.5m) above the
Insert hearth.
The Morsø 5660 Fireplace Insert Zero Clearance Enclosures are approved for installation in the
United States with the following chimneys:
Metal Fab, Inc. Model TG
Security Chimneys Model ASHT
Selkirk Metalbest Model Ultra-Temp
Simpson-Dura-Vent Model Dura-Plus (SDP)
The chimney installation begins with a base plate or anchor plate mounted to the top of the Fireplace
Insert zero Clearance Enclosure. Before the base plate is installed on the enclosure top, the flexible
stainless steel flue connector (provided with the enclosure) that will connect the Insert to the chim-
ney system must be attached to the base plate using the four provided sheet metal fasteners. See
FIG. 1.
Next, insert the anchor plate/flex connector assembly down
through the hole in the top of the enclosure. Use the four
provided sheet metal fasteners to secure the base/anchor
plate to the enclosure top.
Next slide the stainless steel 45° slip connector elbow all
the way onto the stainless flex connector in preparation for
installing the Insert.

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-

ELECTRICAL CONNECTIONS
If you are installing the Model 5660 NA with the optional blower, you must have electrical power con-
nected to the single outlet provided on the side of Enclosure Model 95066400. Refer to the National
electrical Code, ANSI/NFPA 70 and other local code requirements. Use a licensed electrician. The
electrical specifications are 120 VAC, 60Hz, less than 1 amp.
OUTSIDE AIR
If the Outside Air Kit is to be installed, remove the Outside Air Cover Plate from the rear of the enclo-
sure. This will allow the outside air duct to pass through the rear wall of the Fireplace Insert Zero
Clearance Enclosure.
VENTILATION AIR
The chase or cavity in which the enclosure is installed must be ventilated with air from outside of
the chase. A minimum of 24 square inches (154.8 square cm) of opening must be provided in the
chase wall no more than 24 inches (609 mm) from the floor of the chase. The opening may be lo-
cated in the floor of the chase between the enclosure and the walls of the chase. The opening may
incorporate an architectural grate or grill as long as the 24 square inch opening is maintained.

HEARTH REQUIREMENTS
When using the Insert in the Fireplace Insert Zero Clearance
Enclosure, the hearth protection requirements are different
than when installing the Insert in an existing masonry fire-
place. The enclosure has been designed to elevate the in-
sert to the minimum distance above the combustible floor
where no thermal floor protection is required. However,
unless the Fireplace Insert Zero Clearance Enclosure will be
installed on a completely non-combustible surface such as
unpainted concrete over earth, spark and ember floor pro-
tection must be provided in front of the insert and enclosure.
This will protect the combustible floor in front of the load
door from spilled coals or embers.
The floor protector can be made from any completely non-
combustible material such as galvanized steel or non-combustible tile backer board. These materi-
als may be covered with decorative non-combustible materials such as ceramic tile. Other non-
combustible materials may be used if there are no gaps or joints between pieces that would allow
coals or embers to reach the combustible floor underneath. Floor protectors meeting the require-
ments of UL-1618 Type 1 are acceptable.
The floor protector must extend at least 8” (203mm) from the sides of the firebox opening making the
minimum total width of the floor protector 39 3/4“ (1010mm). In addition, the floor protector must ex-
tend a minimum of 16” (406mm) in front of the door opening in the United States. See FIG. 8.
In addition, a 3” X 39 3/4 “ (76mm X 1010 mm) sheet metal spark protector strip must be laid under
the junction between the front of the enclosure and the floor
protector to prevent coals or embers from reaching the combus-
tible floor. See FIG. 7 on page 8.
COMBUSTIBLE MANTEL
A combustible mantel and any associated trim may be mounted
to the wall above the Insert. The mantel (or trim) must be a
minimum of 24 1/4” (616mm) above the top flange on the
Insert. See FIG. 9. The mantel may not be deeper than
12” (305mm). 29 1/4”

CUSTOMIZING THE FINISHED APPEARANCE
The facing of the Fireplace Insert Zero Clearance Enclosure may be finished to give a variety of dif-
ferent aesthetic appearances. However, only non-combustible materials may be applied to the face
inside the specified limits for combustible materials. See FIG. 6 on page 8. Outside the combustible
limits, the any surface finish may be used.
For a smooth wall appearance, non-combustible tile backer board may be used as a base for plaster
allowing a seamless transition beyond the combustible limits to traditional wallboard.
For tile, veneer brick or stone, the finish material may be applied over non-combustible tile backer
board. The requirements for the facing material applied inside the combustible limits are:
• The material must be non-combustible.
• The total thickness, including non-combustible backer board and adhesive should not exceed
13/16” (20mm).
• Facing materials should not encroach into the front opening in the enclosure in order to allow
proper insertion of the Insert .
• Combustible trim at the transition to combustible facing material must not protrude into the room
more than ¾” (19mm) from the facing material.

Prepare the Insert
Refer to the Morsø Installation and Operating Instructions for either Model 5660 NA Standard or
5669 NA with New Blower for instructions on how to prepare the insert for installation.
Follow the Blower Installation instructions on page 14 if you are installing the Insert with the optional
blower. Plug the blower power cord into the electrical outlet in the side of the enclosure. Route the
power cord between the insert stand and the enclosure side.
In order to connect the chimney to the insert it is necessary to remove the baffle and firebox liners.
It is not necessary to completely disassemble the insert. Do not remove the cast iron flue collar.
The instructions in the Morsø Insert manual will show you how to do this starting on page 6.
Install the Insert into the Fireplace Insert Zero Clearance Enclosure
1. Using a helper or stove lifter, place the insert on the platform inside the enclosure. Push the in-
sert back into the enclosure opening until the insert flange contacts the facing material. Check to
be sure the insert is centered in the enclosure opening.
2. Adjust the leveling screws until the face plate is level and plumb or aligned with any joints in the
facing material.
3. Reach up through the flue opening and pull down on the stainless steel 45° slip connector elbow
using the handle provided in the elbow. Make sure the connector elbow is full engaged in the
insert flue flange. See FIG. 11.
4. Bend the two tabs over to secure the connector elbow. See FIG. 12.
