1 MY IRON DOG
An EISERNER HUND is a special cast iron stove. It’s a friend for life. Its life
expectancy is about generations and it will do good services to its owners –
therefore treat it well.
Nearly all components of the IRON DOG are made of solid cast iron. Ash
boxes, screws and bolts are made of stainless steel. A special, tempera-
ture-firm color coating protects the surface. All components of this cast iron
stove are manufactured and assembled in Germany with great care

3 SAFETY GUIDELINES
Radiation range
Do not bring inflammable materials within an 80 cm radiation
range of the IRON DOG! Fire risk! Don’t put inflammable objects
on the stove top, under the cast iron stove or in between the rear
of the stove and the wall behind.
First starting-up
Up to the first reaching of the maximum operating temperature
the protective paint hardens out. This can give some smelling nui-
sances. Provide therefore for sufficient ventilation of the installa-
tion area. Open doors and windows. Don’t stay unnecessarily in
the concerned area. Never use products as gasoline, white spirits
or the like to start a fire!
Burning risk
The external surfaces of the IRON DOG become hot, especially
the window of the fire door.
Don’t touch – Burning risk!
Particularly warn children for this. Keep children away from the
heated IRON DOG.
Use safety gloves during operation.

14 User manual (1.9) © 2019 Brunner GmbH
Ashes
Empty the ash pan only when the ashes are cold and keep them
during at least 24 h in a fire resistant container. Fire risk by re-
maining glow! In case of fire, call the fire-brigade!
Chimney fire
In case of a chimney fire, remove all inflammable objects from the
chimney. Beware of flying sparks. Call the fire-brigade!
Fire door
The fire door of the IRON DOG may only be opened for bringing
in wood or for cleaning. During use with open fire door, the stove
is too heavily charged, smoke or fire can come out and glowing
particles can be ejected. There is the danger of a flue gas poison-
ing. The fire chamber of the IRON DOG is also to be kept closed
when the stove is not heated.
4 BASIC PRINCIPLES
Cast iron stoves of the IRON DOG series function according to the prin-
cipal of ‘burning from above’ and are heated with the intermittent burning
method. The wood load degases with beautiful flames in approximately 60
- 70 minutes and produces a heating output between 5 - 9 kW/h depending
on the quantity of wood (1,5 kg - 2,5 kg).

© 2019 Brunner GmbH User manual (1.9) 15
Cast iron stoves of the IRON DOG series are tested according to EN
13240 / EN 12815 and can be used with a closed fire door. Connecting
more than one stove to a chimney is possible if the chimney is suited for
this (ask the chimney sweep).
Air supply to the setting up area
The IRON DOG can only function properly when the combustion air supply
at the setting up area is sufficient. Before heating up make sure there is a
sufficient supply of fresh air. In the building existing mechanisms for com-
bustion air supply should not be changed.
Fuel
Use only suitable burning wood in the indicated quantities and qualities.
Too small amounts of burning wood lead to insufficient combustion quality.
Too large amounts of burning wood lead to overheating and damage to the
equipment. Fire risk!
Heat output
The cast iron stoves of the IRON DOG series are designed to be used with
the intermittent wood burning method; the heat output is determined by the
quantity of wood used and by the distances in time between the firing oper-
ations. The right time to put on more wood has come when the wood has
nearly been burned down to glow.
Combustion air regulation
For a simple operation the air income is regulated with one single air con-
trol rod. Please heat with the given combustion air regulations. Insufficient
combustion air leads to an increased environmental impact, bad efficiency
and creosote in the stove and the chimney.

Heating operation
We recommend using safety gloves during operation, since the operating
elements become hot. Open the door slowly – this way no turbulences de-
velop, which let flue gases escape.
Flue exhaust/heating during transitional periods
The IRON DOG needs sufficient chimney draught for drawing in the com-
bustion air and exhausting the flue gases. It diminishes with rising outside
temperatures and this can lead to problems to start a fire. When outside
temperatures are over 15°C, please check the chimney draught. (for exam-
ple open the door and keep a burning fire lighter at the entry of the flame
channel – flame and flue gases must visibly take off). In case of too little
draught first light kindling and add burning wood when the draught has
been created.

5 FIREWOOD AND HEATING POWER
The combustion process in our devices has been optimized to enhance
their performance and reduce emissions. You can support our efforts to
protect our environment by respecting the following recommendations for
low-emission heating: Use only dry, natural wood with a residual humidity
factor below 20%, or wood briquettes according to DIN EN 17225-3, Class
A1, length >14 cm (5.51 in), diameter >8 cm (3.15 in).
Damp, freshly cut or improperly stored wood has a high water content,
therefore does not want to burn, makes a lot of smoke and gives not much
of heat. Use only firewood which has been stored for at least two years in
a dry place with sufficient air circulation. Because dry wood is much more
calorific, you can save on fuel costs.
For example: Dry wood has a calorific value of approx. 4 kWh/kg, freshly
cut wood only 2 kWh/kg. You will need twice the amount of wood to achieve
the same heating power.

What amount of heat will I get when
buying wood per weight?
500 kg freshly cut wood Water content 50% 500 kg x 2.0 kWh/kg = 1000 kWh
500 kg dried wood Water content 30% 500 kg x 3.3 kWh/kg = 1650 kWh
500 kg dry wood Water content 15% 500 kg x 4.1 kWh/kg = 2050 kWh
What amount of heat will I get when
buying wood per volume (1 cubic
meter = 1 m3)?
1 m3 freshly cut wood Water content 50% 1286 kWh
1 m3 dried wood Water content 30% 1518 kWh
1 m3 dry wood Water content 15% 1550 kWh
Most suitable for use in open fireplaces are all types of hardwood, like
beech or birch. Softwood species (conifers) have a closed-cell structure
which is bursting during combustion, causing glowing embers to be thrown
out of the fireplace. Hardwood is burning more calm and evenly.
You can control the heat radiation intensity by volume of wood and the in-
tervals for stoking up.

Adjusting the heat by reducing the volume of combustion air is wrong! If
there is not enough combustion air available, the energy contained in fire-
wood cannot be completely released. At the same time, the emissions are
rising due to unburned particles.
Too much of firewood or inappropriate fuel types can cause overheating
and damage.
No kind of waste shall be burned in a fireplace!
Waste on fire = Toxins in your garden!
Never use combustible fluids, like petrol or alcohol to light a fire!
Mind the waste incineration ban!
Remember to use only the recommended fuels described in this
User Guide. Unsuitable, not recommended fuels are not allowed
to be burned in a fireplace.
6 SEASONING OF FIREWOOD
After cutting the trees, the wood should be seasoned in an open and dry
place and protected from rain and snow.
The best time to cut trees is from December till February.
Firewood should be stored under a roof or in a ventilated building (shed).
Do not store freshly cut wood in the cellar or in a closed area. It can’t dry
there.

7 AMOUNT OF FUEL
EHeat output regulation by reducing the combustion air is wrong!
By lack of combustion air the calorific capacity of the fuel can’t be set free
completely. At the same time the emissions increase over the unburned
portions.
To large amounts of fuel or unsuitable fuel can lead to excessive heating
and thus to damage.
