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-to3-1985(2ioo°F.)or a code-approved
masonry chimney with flue liner for the USA, and High Temperature(650°C)Standard
ULC 5-629 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 unpredict-
ability 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 Morse)dealer.

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.Re-
fer 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 chim-
ney 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 chim-
ney.The chimney itself is the masonry or prefabricated structure that encloses the flue.Chim-
ney connectors are used only to connect the stove to the chimney.
Double-wall connectors must be tested and listed for use with solid-fuel burning applianc-
es.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(15omm)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.45°vs.90°)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 go degree turns.Slope horizontal runs
of connector upward 1/4 inch per foot(2o mm per metre)going from the stove toward the
chimney.The recommended maximum length of a horizontal run is 3 feet(i 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 in-
structions 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.
Where passage through a wall or partition of combustible construction is desired,the in-
stallation shall conform to CAN/CSA-B365.

i.5 Positioning the stove
Distance to walls and lintel
When the stove is positioned near combustible materials,observe all current local and na-
tional 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 clear-
ances 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 decora-
tive 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.

Distance to furniture
The recommended minimum distance from stove to furniture is 3o inches.Note that some
furniture is more easily affected by heat and may need to be moved to a greater distance.
This is your responsibility.
In addition other combustible materials, away from the stove. In general,a distance of 3o
inches must be maintained between the stove and moveable combustible item such as dry-
ing clothes,newspapers,firewood etc.
1.6 Mobile Home Installation
The Morsm 7110 can be installed in a mobile home if equipped with an outside combustion
air kit,a terminal cap with a spark arrestor,and if it meets the following installation require-
ments: ...
- The stove must be secured to the mobile home structure by bolting through the hearth
pad and into flooring.
- The stove must be installed with a listed Type HT chimney connector,HT Chimney,and
terminal cap with spark arrestor.Never use a single wall connector(stovepipe)in a mo-
bile home installation.
- Floor protection requirements in section 1.5 must be followed precisely.
- In Canada,this appliance must be connected to a 6"(152 mm)factory-built chimney conform-
ing to CAN/ULC-629M,STANDARD FOR FACTORY BUILT CHIMNEYS.Floor protection as
referenced in section T.5 must be followed,as well as use of Canadian Floor Protector.
- Follow the chimney and chimney connector manufacturer's instructions when installing
the flue system for use in a mobile home.
- Outside air kit should be installed according to installation guide in the kit.
- Intake air piping can be installed through the floor into a vented crawl space or through
the wall of the residence to obtain outside air.
- Install in accordance with 24 CFR,Part 328o(HUD).
- NOTE:Top sections of chimney must be removable to allow maximum clearance of 13.5'
from ground level for transportation purposes.

WARNING:
NEVER DRAW COMBUSTION AIR FROM A WALL,FLOOR OR CEILING CAVITY OR FROM
ANY ENCLOSED SPACE SUCH AS AN ATTIC OR GARAGE.
DO NOT INSTALL IN A SLEEPING ROOM.
CAUTION:
THE STRUCTURAL INTEGRITY OF THE MOBILE HOME FLOOR,WALL,AND CEILING/ROOF
MUST BE MAINTAINED(I.E.,DO NOT CUT THROUGH FLOOR JOIST,WALL STUD,CEILING
TRUSS,ETC.)
DO NOT USE A GRATE TO ELEVATE FIRE-BUILD FIRE DIRECTLY ON HEARTH.

Acid Protection
If acid-washing the masonry around the stove,protect the stove surface with an acid-proof

Fresh Air Inlet
Unless there is deemed to be sufficient ambient leakage of air into the room via doorways,windows
and the like,a dedicated fresh air inlet will be needed.This inlet should have 2 square inches(125o
square mm)of free air space.This is particularly important where the room is well sealed,or where
an extractor hood or ventilation system disturbs the natural air pressure.Such an inlet should not
be on a wall that is usually subject to negative pressure from normal wind pattern.Avoid placing the
inlet directly across the room from the stove,thus causing a cold air draft.
