Combustion chamber
1. Position and level the convection box into the fireplace open-
ing. Allen-head leveling bolts can be accessed at the base of
the combustion chamber (under the base liners).
2. Replace and mount the combustion chamber into the
convection box.
3. Connect the chimney liner to the flue collar from inside
the combustion chamber. Guide the flue collar with flue
pipe or liner attached through the circular hole in the
back of the convection box. The flue collar (with chimney
liner connected) is fastened back onto to the combustion
chamber. A fireplace may be constructed in several ways
therefore, if necessary, ask your chimney sweep about
the optimum connection method between the insert and
the chimney.
4. Replace the interior parts in the reverse order when re-
moved. The baffle plate is mounted back over the two
guide bolts. Next, the two M8 center bolts are screwed
in place. The two guide bolts are removed and the last
two M8 bolts inserted and screwed in. Firebox liners
and fireproof materials are put back in the following or-
der: the rear liner, the two side liners, and the two bot-
tom liners. The fireproof insulation mat is carefully put
in place on top of the baffle plate. Finally, the last liner is
put back in place (in front, centered on the baffle plate
and slanted up towards the smoke exit hole). Caution:
The liners are very porous and must be handled with
great care. The stove door is repositioned on the hinges
with the hinge pins. Remember to put the spilt pins and
the brass washer back in place on the upper hinge. If the
insert ever have to be removed for the purposes of in-
specting the fireplace insert and fireplace it can be done
by using the instruction for the installation (page 6-8) in
the reverse order of which it was installed.
Metal Tag
Where a masonry fireplace has been altered to accommodate the 5660 Fireplace Insert, a metal
data tag (enclosed) should be attached to the masonry fireplace using screws or nails. The tag
should be easily visible should future homeowners wish to remove the 5660 Fireplace Insert at
a later date.

1.1 The chimney / flue system
Note that the flue system must be independently secured and must not rely on the stove
for support.
DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE SERVING ANOTHER APPLIANCE.
(Several flues may run up a single chimney stack; use one flueway per appliance).
Use a residential type masonry or listed type HT factory-built chimney.
High Temperature (H.T.) Chimney Standard UL-103-1985 (2100º F.) for the USA, and High
Temperature (650ºC) Standard ULC S-629 for Canada.
This fireplace insert must be installed with a continuous chimney liner 6'' diameter extending
from the fireplace insert to the top of the chimney. The chimney liner must conform to the
class 3 requirements of CAN/ULC-S635, Standard for Lining System for Existing Masonry or
Factory-Built Chimneys and Vents, or CAN/ULC-S640, Standard for Lining Systems for New
Masonry Chimneys.
The internal dimensions of the chimney connector and chimney must not be less than 6 inch-
es diameter (or equivalent cross section), and should not be significantly larger than this. Too
large a section will tend to allow the flue gases to cool excessively, causing sluggishness or
unpredictability in the stove's performance.
We recommend the length of the chimney system should be at least 16 feet (not required)
above the stove in normal domestic situations, measured from the flue collar to the top of
the chimney.
Local conditions like for example - roof constructions, large trees nearby and high altitude,
may influence the chimney draft and height. Therefore, contact the local professional chim-
ney sweep or your Morsø dealer.
A factory-built chimney should consist of:
- Connector, rigid or flexible (between flue collar of insert and flue liner)
- Insulated High Temperature Flueliner (16 feet)
- High Temperature prefabricated Chimney Cap
Do not connect to any air distribution duct or system.
Important: If the installation instructions are not followed carefully, it may cause dan-
gerous situations like chimney - and house fires. Follow the instructions carefully and
do not deviate from them as it may cause injuries to people or property.
