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 5660 Standard Insert meets the U.S. Environmental Protection Agency’s emission

limits for wood heaters sold on or after July 1, 1990

The Morsø 5660 Standard Insert have been tested by OMNI-Test Laboratories, Inc. The test

standards are UL 1482-1998 for the United States and ULC S627-M93 for Canada.

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

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.

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.

The ﬁgure above shows the required ﬁreplace dimension required for the Morsø 5660 Stan-

dard insert.

It is easier to make adjustments to the masonry surrounding the insert, when the heavy cast

iron is not connected to the steel box. Use the steel box as a template for the masonry ad-

justments. Allow extra room for installation, especially above the insert.

Minimum Masonry ﬁreplace size

Height (A) Depth (B) Width (C)

Inches/mm. 21¼” / 540 mm 19¼” / 490 mm 28¾” / 730 mm

The stainless steel connector must be at least 8 feet in length.

The chimney must have a clay liner or a stainless steel liner.

Do not move bricks or mortar from the existing ﬁreplace.

Remove or lock existing ﬁreplace dampers in the open position.

The stainless steel chimney liner (ﬂexible or rigid) is available from most specialty stove retailers.

The installation may be used with a factory built or mansonry ﬁreplace. Be sure to fulﬁll all

requirements.

Your Morsø 5660 Standard Insert is fully assembled when

you receive it. This ensures optimum protection during

transport.

However, in order to connect the stove to your chimney

installation, it is necessary to dismantle the stove’s ﬂue

collar.

This may only be done by disassembling the combustion

chamber and take it out of the insert box.

The Morsø 5660 standard weighs 300 lbs. In order to avoid

damages when unpacking and installing the stove, it is

recommended that two persons carry out this task. Likewise,

it is advisable to use an underlay (cardboard, rug, or the like)

for placing parts during the installation.

Stove door

Firstly, dismount the stove door. Using the allen key

supplied, loosen the allen screws at each hinge pin and lift

up the two hinge pins, and dismount the door.

Note: The brass washer in the upper hinge is loose and must

be put in place again when remounting the door.

Frame

Detach the frame mounted on the insert box by unscrewing

it with the included Allen key.

Fireproof materials

Now take out the ﬁreproof liners and insulation materials

from the combustion chamber in the following sequence:

Front bottom liner, rear bottom liner, the two side stones,

and the two liners at the rear wall. Finally, remove the

stone and the insulation mat over the bafﬂe plate of the

combustion chamber.

Caution: The liners are very porous and must be handled

with great care.

Bafﬂe plate/secondary air supply

The bafﬂe plate is mounted with four M8 bolts.

The bafﬂe plate is heavy (30 lbs.), and therefore it

is difﬁcult to hold it in place over the four threaded

holes.

For this reason, two guide bolts without heads are

included to facilitate the positioning.

The outermost bolts in each side are unscrewed.

The two guide bolts are now screwed so far into

the outermost holes in each side that the ends are

barely visible (this is necessary in order to bring the

bafﬂe plate down).

Next, the two center bolts are unscrewed.

The bafﬂe plate is now resting on the two guide

bolts.

The bafﬂe plate is removed carefully.

Flue collar

The ﬂue collar with the stop bar is unscrewed from

the stove.

The ﬂue collar is connected to the ﬂue pipe (8 feet

stainless steel connector) or the ﬂexible pipe in your

ﬁreplace/chimney.

A ﬁreplace may be constructed in several ways.

If necessary, ask your chimney sweep about the

optimum connection between the insert and the

existing chimney installation.

The stove is now reassembled in the reverse order

of which it was disassembled.

Combustion chamber

The combustion chamber is unscrewed from the

insert box (two M6 bolts).

Next, the combustion chamber is lifted out of the

insert box.

The positioning of the empty insert box in your

ﬁreplace opening is now relatively easy.

Guide the ﬂue pipe with the ﬂue collar mounted on

down to the circular hole in the insert box.

The combustion chamber is lifted into the insert

box and ﬁxed to the insert box with the two M6

bolts. The ﬂue collar (now connected to the chimney

installation) with the spherical damper is fastened

to the combustion chamber.

The bafﬂe plate is mounted over the two guide bolts.

Next, the two M8 center bolts are screwed in. The

two guide bolts are unscrewed, and the last two M8

bolts are inserted and screwed in.

Fireboxliners and ﬁreproof materials are put back

in place in the following order: the two rear stones,

the two side stones, and the two bottom stones.

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 frame is screwed on again.

The stove door is repositioned on the hinges with

the hinge pins. Remember to put the brass washer

back in place on the upper hinge.

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 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.

Double-wall connectors must be tested and listed for use with solid-fuel burning appliances.

Single-wall connectors should be made of 24 gauge or heavier gauge steel. Do not use

galvanized connector; it cannot withstand the high-temperatures that smoke and exhaust

gases can reach, and may release toxic fumes under high heat. The connector must be 6 inches

(150mm) in diameter.

If possible, do not pass the chimney connector through a combustible wall or ceiling.

If passage through a combustible wall is unavoidable, refer to the sections on Wall

Pass - Throughs. Do not pass the connector through an attic, a closet or similar

concealed space when installing the chimney connectors.

It is important to keep the ﬂue gases moving smoothly in the right direction. Do not vent into a

large void at this location; rather form one continuous section all the way up. Use mild bends

(e.g. 45º vs. 90º) rather than sharp angles where a change of direction is required. All parts of

the venting must be accessible for cleaning purposes.

In horizontal runs of chimney, maintain a distance of 18 inches from the ceiling. Keep it as

short and direct as possible, with no more than two 90 degree turns. Slope horizontal runs of

connector upward 1/4 inch per foot (20 mm per metre) going from the stove toward the chimney.

The recommended maximum length of a horizontal run is 3 feet (1 metre), and the total length

should be no longer than 8 feet (2.5 metres).

Information on assembling and installing connectors is provided by the manufacturer’s

instructions exactly as you assemble the connector and attach it to the stove and chimney.

Be sure the installed stove and chimney connector are correct distances from near by

combustible materials. See the clearance paragraph page 12.

1.2 Flue Connection

The stove is supplied from the factory with a ﬂue collar ﬁtted to the top plate.

The ﬂue collar is from the factory prepared for ﬁtting the enlosed 6 inche adapter.

Use a 24 MSG black or blue chimney connector or listed double wall chimney connector. Refer

to local codes and the chimney manufacturer’s instructions for precautions required for passing

a chimney through a combustible wall or ceiling. Remember to secure the chimney connector

with a minimum of three screws to the product and to each adjoining section.

Position the stove and connect to the ﬂue system.

Wear gloves and protective eyewear when drilling, cutting or joining sections of chimney

connector.

1.3 Connection to the existing chimney

A Chimney connector is the double-wall or single-wall pipe that connects the stove to the

chimney. The chimney itself is the masonry or prefabricated structure that encloses the ﬂue.

Chimney connectors are used only to connect the stove to the chimney.
