INTRODUCTION
Morso Jernstoberi A/S retained OMNI to perform U.S. Environmental Protection Agency (EPA)
third party certification on the 6100 B frestanding room heater. The 6100 B is a cast iron
freestanding wood burning room heater. The firebox is constructed of cast iron. Usable firebox
volume was measured to be 0.5050 cubic feet and the stove is vented through 6” flue collar
located on the stove top.
Testing was performed at Danish Technological Institute (DTI) located at Kongsvangalle 29,
DK-8000 Aarhus C, Denmark. Report number 300-ELAB-2381-EPA dated August 27, 2019
was generated by DTI and submitted to OMNI for review and third-party certification.
This report is organized in accordance with the EPA-recommended outline and is summarized in
the Table of Contents immediately preceding this section. The results in this report are limited to
the item submitted.
SAMPLING PROCEDURE
The 6100 B was tested in accordance with the U.S. EPA 40 CFR Part 60, Subpart AAA –
Standards of Performance for New Residential Wood Heaters using EPA ASTM E2515 and
E3053 per EPA Alt-125’s requirements for cordwood testing in accordance with the CFR. No
28R. Particulate emissions were measured using sampling trains consisting of two Teflon coated
47mm filters (front and back).
The model 6100 B was tested for thermal efficiency and carbon monoxide (CO) emissions in
accordance with CSA B415.1-10 using Birch cordwood.
SUMMARY OF RESULTS
The weighted average emissions of the four test runs included in the results indicate a particulate
emission rate of 0.67 grams per hour. Particulate emissions were sampled on one of the high
burn fuel loads. The 6100 B results are within the emission limit of 2.5 g/hr for affected
facilities tested with cordwood, manufactured on or after May 15, 2020.
The proportionality results for all 3 test runs were acceptable when calculated at a 10-minute
sample rate. Quality check results for each test run are presented in Section 2 of this report.

INDIVIDUAL RUN SUMMARIES
Run 1 - HF Test procedures followed to produce a high burn rate with a primary air setting of
fully open. Observed burn rate was calculated at 1.81 kg/hr. Emissions results
were calculated using particulate sampling from kindling, start-up fuel, and test
fuel load combined (cold to hot). Burn rate, and efficiency were calculated using
data from the test fuel load only (hot to hot). No sampling anomalies occurred;
this test run was determined to be valid for inclusion in the weighted average.
Run 2 - MF Test procedures were followed to produce a medium burn rate with a primary air
setting of 2 mm open from the factory set minimum setting. Observed burn rate
was calculated at 1.25 kg/hr. Emissions and efficiency results were calculated
using a hot to hot burn cycle, a coal bed generated by the high burn procedure was
used. No sampling anomalies occurred; this test run was determined to be valid
for inclusion in the weighted average.
Run 3 - HF Test procedures followed to produce a high burn rate with a primary air setting of
fully open. Observed burn rate was calculated at 1.74 kg/hr. Emissions sampling
did not occur during this procedure, it was conducted to create a coal bed for run
4.
Run 4 - LF Test procedures were followed to produce a low burn rate with a primary air
setting of full closed, a factory installed stop is used to prevent the air control
from fully closing. Observed burn rate was calculated at 0.95 kg/hr. Emissions
and efficiency results were calculated using a hot to hot burn cycle, a coal bed
generated by the high burn procedure was used. No sampling anomalies
occurred; this test run was determined to be valid for inclusion in the weighted
average.

Model Similarities
All versions of the 6100 B series share the same firebox, flue, and combustion air system. Model
differences are limited to variations of the pedestal base.
Model 6140 B was the tested model, it sets on a short pedestal base that is approximately the same
diameter as the stove body.
Model 6143 B has a taller pedestal similar in diameter as the 6140 B that is offered with and without a
wood storage compartment.
Model 6148 B has a pedestal that is similar in height to the 6143 B but has a reduced diameter between
the base and the firebox.
Model 6170 B has no pedestal, it is designed as a wall hanging appliance.
Photos of these variations are in Appendix 26 of DTI report number 300-ELAB-2381-EPA.

Installation of woodburning stoves must be safe and legal.
The installation must conform standard CAN/CSA-B365, Installation Code For
Solid-Fuel-Burning Appliances and Equipment
Make-shift compromises during installation can have consequences, the Installation of
the woodburning stoves must be safe and legal.
If your Morsø stove is not installed correctly, it may cause a house re. To reduce the risk
of re, the installation instructions must be followed carefully. Contact the local building
ocials about restrictions and installation inspection in your are
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 oor protection must be adequate and must be made correctly according to the
requirements.
All neccessary approvals are needed from the local building ocials.
The data plate, which is located on the back of the stove, provides information regarding safety
testing information, name of certied testing laboratory, and installation requirements.
Installation requirements vary in dierent districts, and the local building ocials have the nal
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 dan-
gerous situations like chimney - and house res. 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 re bricks are rmly in position and have not shifted in tran-
sit. Check also that the air control works freely.
Before starting the initial re, make sure that the baes is placed correctly.
Standard Accessories
A Morsø glove and ceramic ue connection gasket are standard accessories that usually can
be found in the ashpan or rebox area.
1.2 The chimney / ue system
Note that the ue system must be independently secured and must not rely on the stove
for support.
The stove must not be connected to a chimney ue serving any other appliance.
(Several ues may run up a single chimney stack; use one ueway per appliance).
Use a code-approved masonry chimney with a ue liner 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 ue 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 inch-
es diameter (or equivalent cross section), and should not be signicantly larger than this. Too
large a section will tend to allow the ue 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 ue collar to the top of
the chimney.
Local conditions like for example - roof constructions, large trees nearby and high altitude,
may inuence the chimney draft and height. Therefore, contact the local professional chim-
ney sweep or your Morsø dealer.

The stove is supplied from the factory with a round blanking plate blocking o the top and
rear ue exit (behind the rear shield plate). A ue collar are placed in the rebox area.
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 tted 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 ue collar and
swap their positions. Re-secure by pushing down and tighten the enclosed screws.
Position the stove and connect to the ue 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
ue. Chimney 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 (150mm) in diameter.
If possible, do not pass the chimney connector through a combustible wall or ceiling. If pas-
sage 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 install-
ing the chimney connectors.
It is important to keep the ue 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 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.

DK ENG 1.5 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 (replace 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 eects 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 oor 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 30 inches. Note that some furniture
is more easily aected by heat and may need to be moved to a greater distance. This is your respon-
sibility.
In addition other combustible materials, away from the stove. In general, a distance of 30 inches must
be maintained between the stove and moveable combustible item such as drying clothes, newspa-
pers, rewood etc.

DK ENG 1.6 Mobile Home Installation
(Mobile home installation is only applicable for USA)
The Morsø 6100 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 requirements:
- The stove must be secured to the mobile home structure by bolting through the hearth pad
and into ooring.
- 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 mobile 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 1.5 must be followed, as well as use of Canadian Floor Protector.
- Follow the chimney and chimney connector manufacturer’s instructions when installing
the ue 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 oor into a vented crawl space or through
the wall of the residence to obtain outside air.
- Install in accordance with 24 CFR, Part 3280 (HUD).
- NOTE: Top sections of chimney must be removable to allow maximum clearance of 13.5’
from ground level for transportation purposes.
2.0 Operation
2.1 Before you start ring
For use with solid wood fuel only. Do not overre, if heater or chimney connector glows
you are overring. Inspect and clean chimney frequently. Under certain conditions of use
creosote buildup may occur rapidly. Because of risk of smoke and ame spillage, operate
only with door fully closed.
CAUTION:
Hot while in operation. Keep children, clothing and furniture away. Contact may cause
skin burns.
DO NOT USE CHEMICALS OR FLUIDS TO START THE FIRE
DO NOT BURN GARBAGE OR FLAMMABLE FLUIDS
DO NOT USE A GRATE, ANDIRONS, OR OTHER WAYS OF ELEVATING THE FIRE - BUILD
FIRE DIRECTLY ON HEARTH.
DO NOT USE GASOLINE, GASOLINE-TYPE LANTERN FUEL, KEROSENE, CHARCOAL LIGHT-
ER OR FLUID OR SIMILAR LIQUIDS TO START OR FRESHEN UP A FIRE IN THIS HEATER. KEEP
ALL SUCH LIQUIDS AWAY FROM THE HEATER WHILE IT IS IN USE
Choosing your fuel
All types of natural wood can be burned on your stove, but they must be well-seasoned and
dry. Once the wood is cut to length, it should be split down middle - to suit the dimensions
given below - to allow moisture to evaporate.Cut the wood to a length of max 12 inches (30
cm) and approx. 3 to 3.5 inches (7-8 cm) in section. If you can weigh your wood, aim for around
2 lbs. For correct combustion and heat output, wood fuel should contain no more than 20%
moisture; this can easily be checked by using the Morsø Moisture Meter (part # 62929900).
To naturally season wood fuel, stack and store it under cover in an airy location where fresh air
can move through each piece. Some soft woods may take as little as one good summer to sea-
son whereas harder woods such as oak, maple, and elm may require seasoning up to 18 months.
Avoid overly dry wood that is gray in color as under certain conditions it can cause performance
problems, such as back-pung and sluggishness. Well seasoned wood will be light to hold and
will show signs of cracking from the center-out in the ends. If your wood spits or sizzles when
b urnt, and your stove’s door glass persistently mists up, your wood is not properly seasoned.
Never use drift wood (from the sea), whose salt content may cause corrosion, nor construction
wood that may have been impregnated with chemicals.
To optimize eciency:
Burning wet wood has a negative impact on eciency
CAUTION Do not place fuel within the installation clearances for the stove or within the
space required for loading fuel and ash removal.
Starting the First Fire
The initial re should be small, so that the stove paint can cure and the main plates of the
stove can settle into position. Some fumes will be given o by the paint. Ventilate the room
during this phase.
The setting of the air control, lighting techniques and loading intervals will depend on chim-
ney draft, the fuel used, the heat required and so on. Some basic techniques are outlined
below.
WARNING:
NEVER DRAW COMBUSTION AIR FROM A
WALL, FLOOR OR CEILING CAVITY OR FROM ANY ENCLOSED SPACE SUCH AS AN AT-
TIC 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.
Note:
Acid Protection
If acid-washing the masonry around the stove, protect
the stove surface with an acid-proof cover.
Fresh Air Inlet
Unless there is deemed to be sucient 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 (1250 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 nega-
tive pressure from normal wind pattern. Avoid placing the
inlet directly across the room from the stove, thus causing
a cold air draft.

12 13
DK ENG In principle
Your stove should be with Primary and Secondary air and Pilot air inlets.
Primary Air is controlled using the lever situated over the door. Moving the control lever to
right position will open the air inlet and will allow a supply of preheated air to enter the rebox
via the ‘airwash’ system situated inside the stove and above the glass.
The secondary air is injected into the ue gases above the re resulting in a cleaner, more
ecient combustion process. The supply of secondary air and Pilot air is xed open and is
not adjustable.
For extra safety, your stove should be with a removable handle.
2.2 Lighting and loading intervals
When rst lighting the stove, a large volume of air is needed. When the stove is cold, you
should leave the door open an inch or two for the rst few minutes and open the primary air
supply completely. While the door is open, do not leave the stove unattended.
To form a reasonable bed of ash on the oor of the stove, you should use 2-4 pounds of dry
kindling at the initial lighting. If possible, maintain a 1-1.5 inch (2-3 cm) layer of ash on the
oor of the combustion chamber for added insulation.
1. We recommend using the “top-down” method to light
your wood-burning stove. It is the most environmentally-
friendly method of lighting. Use two relighters and ap-
prox. 2-4 lbs of dry kindling sticks to quickly create a glow-
ing layer of wood. Place the relighters directly under the
top layer of kindling sticks.This minimizes soot formation
on the glass. Soot formation on the glass is often caused
by too vigorous burning in contact with cold surfaces. If
you avoid the formation of soot when lighting the re and
build up a layer of hot embers, you will have minimal soot
formation when getting the re burning again later.
2. The air supply must be fully open.
3. Light the re.
4. After lighting, partially close the door, leaving it open an
inch or two to allow in plenty of combustion air.
5. When the chimney is warm after about 5-10 minutes,
the door should be closed. A suitable layer of ember will
be formed after about 15-20 minutes.
6. When ready to reload, use a poker to spread the embers
across the rebox oor, bringing plenty towards the front
of the stove.
7. Lay two pieces of wood onto the embers. Leave half an
inch or more between each piece.
8. Close the door. Leave the primary air supply fully open.
If it does not light, leave the door slightly ajar to allow the
necessary amount of air in to ignite the wood.
Close the door again once the wood has kindled.
9. After a few minutes, adjust the primary air supply to suit
your heating requirements.
Make sure that there is always enough air to sustain clear,
enduring ames when you reduce the amount of combus-
tion air, and afterwards.
10. For refueling, add a layer of wood while there are still
plenty of live embers, repeat steps 6-9.
We recommend using fuel load with a weight of 3 lbs
(2 pieces) and up to 6 lbs (5 pieces).
Always keep the fuel load beneath the secondary
stainless-steel air box. The space in front and above the air
box is reserved for volatile gas combustion only.

14 15
DK ENG Do not for any reason attempt to increase the ring of your heater by altering the air
control adjustment range outlined in these directions.
Warning: Fireplace stoves must never be left unattended with the door open.
If the door is left partly open, gas and ame may be drawn out of the replace stove open-
ing, creating risks from both re and smoke. We recommend that you t a smoke detec-
tor in the room where the stove is installed.
DO NOT OVERFIRE THIS HEATER. Overring may cause a house re, or can result in per-
manent damage to the stove. If any part of the stove glows, you are overring.
The maximum recommended weight of wood fuel per load is 6lbs (5 split logs).
Under normal ring, the average ue temperature in the stove pipe, measured 20 cm above
the stove, is approx. 300° C (550°F). The maximum ue temperature in the stove pipe must
not exceed 450° C (750°F). If the ue temperature exceeds 450°C (750°F), it is considered
as over ring and may cause premature wear and tear of the stove.
To help gauge the correct running temperature of your stove, we recommend you use the Morsø
Flue Gas Thermometer (part # 62901200). The Flue Gas Thermometer magnetically attaches onto
the stove pipe approx 20 cm (8”) above the stove’s top plate and measures the surface temperature
of the stove pipe. Please see your authorized Morsø Dealer for availability.
Draft conditions
If smoke or fumes come out of your stove when lightning up and reloading, or if the re simply
will not respond, a poor draft is almost certainly to blame. (In a very few cases, there may be
insucient fresh air getting into the room - see installation advice above). Take advice from
your stove supplier on how best to upgrade your ue system to improve draft.
Rules of woodburning
If you want less heat, put fewer logs on the stove and reduce the amount of air. It is still impor-
tant to maintain a good layer of embers.
Less heat - less wood - less air
Greater heat - more wood - more air
Soot deposits will settle on the glass if the stove is run too slowly or if your wood is not well
seasoned.
We would strongly recommend that you do not leave your stove alit at night. It harms the
environment, and constitutes very poor use of the wood, as the gases in the wood do not
ignite at the low temperature, but settle as soot (unburned gases) in the chimney and stove
instead.
Carbon monoxide detectors
It is required in some jurisdictions to install smoke and carbon monoxide detectors where
heaters are installed. Install at least one smoke detector on each oor of your home
to ensure your safety. It should be located away from the wood appliance and close to
the sleeping areas. Locating a smoke detector too close to a wood appliance can cause the
smoke detector alarm to sound if a pu of smoke is emitted while the wood appliance door
is open during reloading. Follow the smoke detector manufacturers placement, installation,
and maintenance instructions
3.0 Maintenance
When perfoming maintenance on your stove, always protect yourself, using safety gog-
gles and gloves.
3.1 Exterior Maintenance
The stove surface is painted with heat-resistant Senotherm paint. It is best kept clean by
vacuuming with a soft brush attachment or by wiping with a lint-free cloth.
Over a period of time, the painted surface may become slightly grey. A can of Morsø touch-up
spray paint should be available from your stove supplier. This can be applied - in accordance with
the instructions - in just a few minutes. When rst ring after touching up, the stove will give o
a slight smell as the paint cures. Make sure to ventilate the room well during this phase.
3.2 Internal maintenance
Glass
If the stove is generally run at the correct temperatures, there should be little or no dirt on
the glass. If dirt does settle during lighting, most will burn o as temperatures increase.For
heavier deposits that will not burn o, use morsø glass cleaner, applied when the glass is
cold, in accordance with the instructions. Never use abrasive cleaners on the glass surface.
Reasons for dirty glass
- Fuel too wet
- Logs too large or not split
- Combustion temperatures too low
Do not clean the glass while hot
Replace broken glass immediately.
Do not operate your stove if the glass in the door is damaged.
If you need to replace the glass, it should be replaced with the high temperature ceramic
class supplied by Morsø, contact your Morsø dealer.
Installing the glass
Never install the glass when the stove is in function.
Ceramic glass replacement
Ceramic glass cannot be recycled because it has a
higher melting point that ordinary glass. If ceramic
glass is mixed with ordinary glass, the raw mate-
rial is spoiled, and the reclaiming process may be
halted. Take care that the ovenproof glass does not
end up among ordinary recycled waste. That will
be a great benet to the environment.
Note: Should be handed in to a recycling sta-
tion as ceramic glass.
