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 7110 meets the U.S. Environmental Protection Agency’s emission limits for wood
heaters sold on or after July 1, 1990

The Morsø 7110 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

11,000 to 25,000 Btu´s.

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.

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.

1.1 Checking loose parts in the stove

After unpacking, check that the fire bricks are firmly in position and have not shifted in transit.
Check also that the air control works freely.

See separate Assembly Instructions for Legs, Fitting for handle, and Baffles

Before starting the initial fire, place the two cast iron baffles above the three stainless pipes
that supplies the secondary air. The baffles are enclosed in the stove on delivery. Afterwards,
place the carbowool blanket carefully above the two cast iron baffles.

Make sure that the upper heating shield, the cast iron baffles, and the carbowool blanket are
placed correctly before the fire is started.

Standard Accessories

A Morsø glove and ceramic flue connection gasket are standard accessories that usually can
be found in the ashpan or firebox area.

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
requirements.
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.

1.2 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.) or a code-approved
masonry chimney with flue liner 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.

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 8.

1.3 Flue Connection

The stove is supplied from the factory with a flue collar fitted to the top plate and a round blanking
plate blocking off the rear flue exit (behind the rear shield plate).

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.
The collar can be fitted to the rear outlet. Simply knock out the round panel on the rear heat
shield plate to reveal the cast iron plate. Untwist the blanking plate and the flue collar and swap
their positions. Re-secure by pushing down and tighten the enclosed screws.
Position the stove and connect to the flue system.

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

1.4 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.

Where passage through a wall or partition of combustible construction is desired, the instal-

lation shall conform to CAN/CSA-B365.

1.5 Positioning the stove

Distance to walls and lintel

When the stove is positioned near combustible materials, observe all current local and national
building regulations with regards to clearances. Whatever regulations apply to your area, do
not in any case install the stove within 8 inches of combustible materials around the sides or
16 inches above the top of the stove (fireplace installations require greater clearances above
the stove - see below in the clearance chart). These distances may need to be increased if the
materials are sensitive to heat. Note also that wall paper and other decorative materials may
become detached with the effects of heat and care should be taken to ensure that they do not
fall towards the stove in such an event.
When the stove is positioned near non-combustible materials, a gap of 4 inches or more is
recommended for cleaning purposes and to ensure that heat circulates around the stove and
out into the room.

If using rear exit, the floor protection must extend beneath the chimney connector and 2-in
beyond each side.
