4 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 nuisances. Provide therefore for sufficient ventilation of the installation
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.
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 remaining 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 poisoning. The fire chamber of the IRON
DOG is also to be kept closed when the stove is not heated.

5 BASIC PRINCIPLES
Cast iron stoves of the IRON DOG series function according to the principal 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).
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 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
combustion 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 operations. 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 control 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 develop, which let flue gases esca.
Flue exhaust/heating during transitional periods
The IRON DOG needs sufficient chimney draught for drawing in the combustion 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 example 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.

6 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 firewood with a water content below 20%
or wood briquettes according to DIN 51 731, size class HP2.
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 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.
Water content g/kg wood Calorific value kWh/kg Consumption raised by %
very dry 100 4,5 0
stored for 2 years 200 4 15
stored for 1 year 350 3 71
freshly cut wood 500 2,1 153
Natural firewood (picture left) is the best
fuel for fireplaces, but you can also use
wood briquettes complying to DIN 51 731,
size HP2 (picture right).
How much thermal energy you will get, if you buy
wood by 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

© 2013 Brunner GmbH User guide IRON DOG 06 15
How much thermal energy you will get, if you buy
wood by 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 intervals 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 firewood 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 as aids for lighting fire!
Mind the waste incineration ban!
Remember to use only the recommended fuels described in this User Guide. Improper, not
recommended fuels cannot be burned in a fireplace.
7 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.

8 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.

9 OPERATION
Grill and barbecue functions which are described here are only available in the models with grill function.
Consider also the denomination of the components related to this in the chapter 'Technical Data’.
Before initial operation
Before initial operation please grease the stove top and covers, the grill grate and the oven with edible oil
and heat up the Iron Dog 06.
Firing door
Note that the firing door is opened in a clockwise direction. (See
picture; Auf=open; Zu=closed)
Combustion air regulation
The air control push rod (5) can be put in three different positions.
Start up Nominal heat output Closed
Combustion air completely open
for heating up
Full heating Combustion air completely closed
In case of unfavorable chimney draught the start-up valve (4) can be opened by pulling. The combustion
gases now take a shortcut to the chimney (the combustion gases don’t flew around the oven (6) and the
stove top on the left (3) is not heated).
As soon as the fire burns strongly, close the start-up valve by pushing in its control lever completely. See to it
that the combustion air control is still in the start-up position and that the fire door is closed.
Consider the remarks in the chapter ‘Heating with the Iron Dog'!

Backing - Grilling - Cooking
The Iron-Dog 06 is a cooker in its best sense. One
can cook and bake with it, and once the fire burned
down, one can perfectly grill above the glow.
As grilling takes place inside the cooker, important
odors are evacuated by the chimney.
Illustr.7: Grill grate in stow compartment
To get an optimal temperature in the oven and on the stove top, the start-up valve must be closed. Push in
the ‘start-up valve push rod’(4) completely.
The grill grate is made of solid cast iron and thus heavy. When handling the grill grate always insert
the levers completely into the openings intended for this to avoid the grill grate from falling.
The cookplate. The 2-piece stove top of enameled cast iron can be used as heat- and cookplate. The
highest temperature is above the fireplace; to the side the temperature is less. To warm up fast water or a
meal the pot is put above the fireplace. By moving the cook pot to the side above the oven, the danger of
burning or boiling over diminishes.
Caution: in a hot stove only a small amount of wood is needed – otherwise the temperature becomes too
high for cooking. It takes some practice and skill to cook and bake with a woodfire. One has to learn to know
the cooker through experience.
The oven. Combustion gases flow around the iron cast oven and make it excellent for roasting and baking.
Please take care that the temperature does not accidentally get too high. On the enclosed thermometer the
oven temperature can be controlled.
Tip: put the thermometer in the oven during normal heating operations and observe the temperatures and
the heating capacity of the oven.
Caution: burn only a small amount of wood in a heated stove and observe the spices in the oven. It is
recommended to turn around the roast or baking dishes several times in order to equalize the temperature
differences at the door side or the back side. Otherwise the back side gets too dark or ‘burned’.
Tip: it is better to heat more calmly in the beginning and to add some more wood at the end in order to
improve the „browning“. Good baking takes time.
Grilling/Barbecuing. Using the glow of the wood
fire in the most beautiful way. Make certain that the
wood has burned down to glow and then close the
combustion air.
The grill grate can be found under the oven in the
stow compartment. It can simply be pulled out and
with the help of the two levers it can be pushed
through the firing door and slid above the glow in the
firing chamber.

© 2013 Brunner GmbH User guide IRON DOG 06 19
Grease the grill grate before each use with baking
brush and edible oil.
At the beginning, put the grill grate on the highest
position in the firing chamber.
Close the firing door and open the pivoting stove top
cover.
Space out the food on the grill grate and close the
stove top cover. Usually the grill grate has an even
heat distribution over its entire surface.
Grill vapors are evacuated along the smoke
channels towards the chimney.
For inspection and to turn around the grilling food,
open the stove top cover and then close it again.
With weak glow, push the grill grate on the lower
stages.
Cleaning: clean the enameled surfaces with a cloth and warm water with some cleaning agent. Persistent
incrustations can be removed carefully with the enclosed brush. Caution: never do this when the stove is
hot. Burning risk!
While grilling in closed areas, never leave the stove top cover above the grill open unattended. Fire
risk!
10 HEATING WITH THE IRON DOG
Control whether the ash pan must be emptied. Minimum distance between ash layer and bottom grate
should be 3 cm.
Bring the push rod in its “Start-up” position. The combustion air can flow strongly on the wood in order to
reach fast high heating temperatures.
Pile wood logs loosely on the bottom grate. Put a fire lighter between the logs and light it on. To start the
fire, use small wood; large wood logs degas and ignite badly in a cold fireplace.
Never use products as gasoline, white spirits or the like to start a fire!
Close the fire door and observe the flame development during the first minutes. If the fire goes out, open
the door slowly and put a new fire lighter between the wood logs and light it on. Check the chimney
draught.
After approximately 10 minutes, bring the push rod in its “nominal heat output” position.
When the wood has burned down (glow phase) new wood can be added. Bring the push rod in its “Start-
up” position for about 5 minutes. Then bring it back in its “nominal heat output” position.

20 User guide IRON DOG 06 © 2013 Brunner GmbH
If no more wood has to be added, bring the push rod in its “closed”position at the end of the combustion,
this is when no flames are to be seen any more.
ATTENTION: Never put the air control push rod in the “closed” position during the starting
up phase or during the nominal heat output phase (lack of air). In case of a sudden oxygen
admission (for example when one opens the fire door) gases present in the fire chamber can
react with the incoming oxygen (deflagration).
The Iron Dog draws its combustion air from the installation area. Consider the combustion air need in
case of simultaneous use of other fire places in the room.
11 ASHES
When burning dry wood and with correct steering of the combustion air, only light and fine ashes remain as a
residue.
The ash pan must be emptied regularly.
Ashes in the fire chamber should not rise over the bottom grate frame.
The ashes can easily be pushed into the ash pan beneath. Pull the slide valve and push the ashes
downward. The ash pan can be taken out with open fire door.
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! In case of fire, call the fire-brigade!
12 CLEANING AND MAINTENANCE
At least once a year at the beginning of a new heating season, should be checked whether in the smoke pipe
and on the baffle plate fly ash has settled. Remove the stove top cover or the entire stove top and remove
eventual fly ash with an ash cleaner. In order to have a better access to the smoke channels, the baffle plate
can be taken out or pushed toward the firing door.
Examine the chimney after longer rest breaks for obstructions.
Some soot on the window can be removed in warm condition with a dry tissue paper. To clean a more
polluted window use a wet paper towel, dab it in the ashes and remove deposits on the glass.
Subsequently wipe with a dry cleansing tissue. Do not use scrubbing tools or aggressive cleaning agents!
The Iron Dog should be examined by your specialized enterprise regularly.
