We congratulate you on your choice of a Morsø stove. Morsø has been
producing some of the world’s best stoves since 1853. If you follow this
installation- and operating instruction carefully, we can assure you
many years of warmth and pleasure.

Optional Accessories

A wide range of accessories (such as handling gloves, fireside tools, glass cleaner and heatproof
paint) are available for use with your Morsø stove. They help with day-to-day running and
maintenance. Contact your Morsø dealer for more information.

The Morsø 1710 Insert meets the U.S. Environmental Protection Agency’s emission limits for
wood heaters sold on or after July 1, 1990

The Morsø 1710 Insert have been tested by OMNI-Test Laboratories, Inc. The test standards are
ANSI/UL-1482 for the United States and ULC S627 for Canada.

The stove is listed for burning wood only. Do not burn other fuels.

Under specific test conditions this heater has been shown to deliver heat at rates ranging from
12,000 to 39,000 Btu/hr.

Cast iron
Cast iron is a live material. There are no two ovens that are identical. This is partly due to the
tolerances of the casting process, partly because the ovens are a work of craftsmanship.
Minor unevennesses may also occur in the cast iron surface.

Installation requirements vary in different districts, and the local building officials have the final
authorization to approve your installation. You should discuss the installation with them before
beginning. Please ask your dealer for further information.

1.0 Installation of your Morsø stove

Installation of woodburning stoves must be safe and legal.

If your Morsø stove is not installed correctly, it may cause a house fire. To reduce
the risk of fire, the installation instructions must be followed carefully. Contact the
local building officials about restrictions and installation inspection in your area.

Before you start installing your stove, make sure that:

- The stove and chimney connection are placed far enough from combustible materials to
meet all clearance requirements.

- The floor protection must be adequate and must be made correctly according to the re-
quirements.
All neccessary approvals are needed from the local building officials.

The data plate, which is located on the back of the stove, provides information regarding safety
testing information, name of certified testing laboratory, and installation requirements.

There are numerous ways of building a chimney. We
will just describe a couple of mountings of the insert.

The MORSØ 1710 insert can be installed as described
below. The 1710 can also be used as a build-in stove with
masonry/chimney construckted for the size of the outer
steel box, as shown on the front page of this manual

1. Remove the existing damper, if there is one. (Fig. 1)

b. Lift the lower baffleplate a bit and hold
in that position. Carefully lift and remove
the two side bricks.

c. Remove the firebrick from the backwall

d. Remove the lower baffleplate

e. The upper baffleplate is removed from
the brackets and lifted out of the fire­champer

f. Unscrew the 2 bolts, which is mounted
to the stainless steel baffle Dismantle the
flue collar. Pull out the cast iron insert
from the steel box

2. It is easier to make adjustments to the mansonry
surrounding the insert, when the heavy cast iron
insert is not connected to the steel box. (see item
a-f page 5). Use the steel box as a template for the
mansonry adjustments

Dismantling the steel-box

a. Lift and remove the front grate.

3. It is important to leave a gap of few millimeters
between the steel box and the mansonry because
of increasing size when warmed up.

If possible leave 25-30 mm. and fill up the gap with

heat resistant insulation material. As shown in
figure A, the steel box must project 10 mm. from
the mansonry. The steel box should be adjusted by
support

1.1 The chimney / flue system

Note that the flue system must be independently secured and must not rely on the stove for
support.

The stove must not be connected to a chimney flue serving any other 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.

The internal dimensions of the chimney connector and chimney must not be less than 6 inches
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 chimney sweep or
your Morsø dealer.

Do not connect to any air distribution duct or system.

Important: If the installation instructions are not followed carefully, it may cause dangerous
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.

material until the bottom becomes horizontal. It

is an advantage to fasten the box by two screws
drilled through the bottom 2-3 cm. from the
corners of the back.

Figure 2:
The connection between the insert and the

chimney is made by a dia. 155 mm. fluecollar,
which is fasten in the smoke pipe socket by the
enclosed selfcutting screws (spoil in the boring
dia. 3 mm.) and tightened by the enclosed
fireproof seal. Tighten between smoke pipe and
chimney with fireproof clay. It is important to use
a pipe bush and fireproof seal in order to avoid
cracks in the fireproof clay, caused by thermal
exspansion of the smoke pipe. If no access door
exists beforehand, as shown in figure 2, it may be
an advantage to mount one. Thus the mounting of
the smoke pipe is facilitated and some times it is a
demand from the building authorities. In order to
obtain a correct execution of the above, it might be
an advantage to consult the local chimneysweep
or the building authorities.

4. Lift and push the insert in its place in the steel
box. Assemble the internal of the stove and flue
collar. (see item a-f page 5, reverse order)

5. The initial fire should be small in order to properly
cure the cast iron parts. Allow the stove to warm up
before creating a very hot fire. Never let the stove
become superheated. Superheating may damage
the casting, fire bricks and the Senotherm painted
finish. Superheating is when any part of the stove,
grates or stove pipe assumes a red glow
