The boiler stove
A boiler wood stove is an advanced type of wood stove that not only provides warmth and ambience, but
is also used to provide hot water to a central heating system in your home. It is an efficient and
sustainable heating solution that will reduce the use of fossil fuels such as gas or oil.
The central heating wood stove has a built-in heat exchanger that transfers the hot water produced by
burning wood to your home's existing heating system. This water can be used for radiators, underfloor
heating or even for heating your domestic water.
Installing a central heating wood stove and connecting it to the existing heating system requires
specialist knowledge. It is advisable to consult a professional installer to ensure the system is installed
correctly and complies with applicable safety and building regulations.
Combination with solar collectors or a heat pump
It is possible to combine your central heating wood stove with solar collectors or a heat pump to create a
hybrid heating system. This makes it possible to theoretically save 100% on gas consumption. The
installer can look into the possibilities of this.
Note: the boiler wood stove cannot be used as a main heating system. It can, however, be used
as additional heating!

Assembly
Delivery of the stove
Check carefully that the stove is in undamaged condition. Please check that no transport damage has
occurred. You should report any damage to the carrier.
Damage to the glass or vermiculite after commissioning is almost always caused by overloading or
incorrect operation. In this case, a warranty claim is not possible.
The right setup location
oEnsure that the installation location is chosen to allow a straight connection to the chimney. The
exact requirements will be specified by your installer or Nordic Fire dealer.
oNordic Fire's boiler wood stoves are usually fitted with a top connection.A rear connection is not
possible.
oThe installation location must be flat and level before setting up the stove. If the stove is not
positioned correctly, excess air may not be able to escape from the stove.
oThe floor on which the central heating stove will be placed must be made of a non-flammable
material. The floor plate must protrude at least 50 cm at the front and 30 cm at the side. So that no
heat can be transferred to the combustible floor.
oThe flue materials should maintain sufficient distance from combustible materials. The distances
indicated on the rating plate and in this manual must be maintained.
oYou must ensure that there are no combustible materials directly in the radiant area of the glass
pane.

Connection to the flue pipe
The connection to the chimney should be provided and checked by a recognised installer. The Nordic
Fire dealer can check whether the flue and chimney are sufficiently safe. In addition, he will check
whether the flue meets the valid regulations.
The necessary connecting materials for the chimney are not part of the delivery of the stove. These
materials are provided by the installer. In any case, the diameter of the chimney must be at least the
diameter of the stove pipe mouth. Alarger diameter is possible, a smaller diameter is not allowed.
Wood-burning stoves are complex technical devices.A safe and trouble-free connection is important
here. Regulations should be observed in this regard.
The flue of a boiler wood stove plays a crucial role in the safety, operation and efficiency of your stove.
Safety
A properly functioning flue ensures the proper removal of combustion gases, smoke and harmful
substances, such as carbon monoxide, released during the combustion process. Carbon monoxide is a
colourless and odourless gas that can be life-threatening if inhaled. The flue prevents these gases from
entering the room, reducing the risk of poisoning and health problems.
Draft and efficiency
A proper flue ensures adequate draft, also known as chimney draft. Chimney draft is essential for proper
wood combustion and efficient stove operation. A good draught ensures sufficient air supply and
optimum combustion, where the wood is fully consumed and the heat is efficiently utilised. Poor draught
can lead to incomplete combustion, reduced efficiency and creosote formation.
Preventing condensation
During the combustion process, water vapour is produced that is present in the flue gases. Upon cooling,
this water vapour can condense and mix with the flue gases, creating creosote. Creosote can
accumulate in the flue gas duct and lead to corrosion, blockages and increased fire risk.A properly
constructed and insulated flue gas duct ensures efficient removal of condensation, extending the life of
the duct and reducing the risk of creosote development.
Cleaning and maintenance
The flue pipe requires regular maintenance and cleaning. Regular inspection and cleaning of the flue gas
duct help remove accumulated creosote, reducing the risk of chimney fire. Moreover, a clean flue can
improve the efficiency of the stove by ensuring unobstructed airflow. The flue should be cleaned at least
annually by a recognised chimney sweep.
A central heating wood stove is prone to insufficient chimney draft. This can cause smoke to enter the room
during refuelling.
Important when connecting tot he chimney:
oThe chimney must be checked in advance by the Nordic Fire installer for leaks and the condition of
the chimney.
oA brickwork, uninsulated flue is not allowed! A masonry flue must be lined with a suitable inner pipe
which is insulated. For example, with vermiculite granules. The lining must be smooth and at least
the diameter of the stove.Minimale trek in het kanaal is tenminste 17 Pa.
oThis draft should be measured in advance to ensure that the draft in the flue is sufficient. As soon as
the chimney draft exceeds 20 Pa, a draft limiter should be installed. If the draft is in the flue, smoke
may enter the room when opening the door.
oAll flue gas connections must be tight
oIt is not allowed to connect more than one stove to a chimney.
oIf the draught is insufficient, smoke may enter the room when filling the stove. You can prevent this
to some extent by carefully opening the door slightly first and then slowly all the way in before
topping up with wood.

MANUAL WOOD BOILER STOVE
10
CAUTION: A boiler wood stove with a high efficiency (read: high resistance) is susceptible to an
improperly functioning chimney.
We recommend using a fully insulated duct with a diameter of at least the connection of the stove. A
larger diameter will improve draught and is therefore advisable. Bends in the duct should be avoided as
much as possible.Abrick channel is not allowed, as it can cause too many problems with the draught
due to cooling and resistance.
External air supply
The boiler wood-burning stove is equipped with an external air supply which can be used in a poorly
ventilated house (passive / new-build house). However, the wood stove is not completely sealed. If a
negative pressure situation may arise, additional ventilation should be provided to prevent this. Even if
the stove is connected with an external air supply!
This external air supply can be connected to the outside air or other ventilated room if the room is
insufficiently ventilated.
Please note that an extractor fan present in the room or adjoining room can cause a large air extraction
which can suck smoke gases out of the stove.An extractor hood without external ventilation must not be
used at the same time as the wood stove.
The external air connection must not be reduced. The length may be a maximum of 5 metres with a
maximum of two 90-degree bends. In addition, care should be taken to ensure that the air supply cannot
be blocked by small animals.A grille is necessary for this purpose.
oIf there is an underpressure situation in the installation room, the stove must not be put into operation.
Contact your dealer for this.
oWhen connecting the external air supply to the outside, cold moist air can enter the stove. This can
cause rust if no measures are taken when the stove is not in use.
oIf the external air supply is not connected, always ensure adequate ventilation.
The installer can determine whether the external air supply should be connected. This depends
entirely on your living situation.

Connection to the central heating system
A central heating wood stove functions well if it is properly connected to the central heating system.
However, once this is not done, or if the stove is not suitable for the central heating system, the radiators
or underfloor heating may not heat up optimally.
The guarantee on the boiler wood stove is only applicable if it has been installed by the Nordic Fire
dealer - installer. They should observe this manual as well as the applicable legal regulations.Annually,
the cooling coil should be checked for leaks. They should also check that the cooling protection and
overpressure protection can function properly.

The technology
Thermal safety (temperature protection)
In the Netherlands, it is compulsory for a boiler wood stove to be fitted with a cooling coil, which is
integrated in the heat exchanger. This cooling coil must be fitted with a temperature safety device 95
degrees.As soon as the temperature in the stove gets too high, cold water will flow through the cooling
coil, indirectly cooling the central heating water. The water supply that is connected should not be able to
be shut off.
The temperature safety device is an emergency cooling device and can fail after it has cooled the heater
by overheating. The temperature safety device must then be replaced immediately.
A central heating wood stove without a (working) cooling coil and temperature safety device
must not be put into operation.
Important:
1. For trouble-free operation, the water pressure should be between 0.8 and 2.5 bar.
2. It must not be possible to shut off the water supply manually.
3. The drain must be discharged into the sewer via a funnel.
4. The drain line must be free.
5. Temperature protection should be checked annually.
If the water pressure drops, the central heating wood stove should not be used.
Overpressure protection
A central heating wood stove should be fitted with an overpressure safety device. This means that it
should be connected in open connection with the stove. The outlet of the pressure relief device should be
in a frost-free zone. The outlet should be visible and lead into a funnel. This pressure relief device should
be checked annually.
Warning: During operation of the central heating wood stove, steam or hot water may flow from
the pressure relief valve. Do not close the outlet.
Thermal mixing valve
A thermal mixing valve is necessary to install with the central heating wood stove. The opening
temperature of the mixing valve should be at least 60 degrees.A thermal mixing valve prevents deposits
of creosote in the chimney and stove during operation. Only at start-up can some creosote form.
At the start-up of the boiler wood stove, the thermal mixing valve ensures that the water flows directly
back to the stove via the bypass. This heats up the central heating stove before it releases heat to the
central heating system. This also keeps the temperature in the stove at least 60 degrees.
Warning: Without a 60-degree thermal mixing valve, there is an increased risk of chimney fire in
the short term!

MANUAL WOOD BOILER STOVE

Filling and bleeding
Proper venting of the central heating system is necessary to ensure proper operation of the boiler wood
stove. Make sure there are sufficient vents at high points at branch points. Venting the system is often
problematic and can take a long time.
Tips on filling and bleeding:
oThe heating and especially the pumps should be switched off.
oFilling should be done via the return.
oThe bleed valves should be opened before filling. The valve should be closed immediately as
soon as water comes out.
oOpen the filling valve slowly when filling
oThe pump can be vented by opening the central screw. A pump can make noise. This is mainly
caused by air. This air is difficult to remove and may take a longer time.
oFor trouble-free operation, the water pressure should be between 0.8 and 2.5 bar.

MANUAL WOOD BOILER STOVE
16
Commissioning
Important to know:
oA central heating wood stove should never be used if it is not connected to the central heating
system. High temperatures can damage the heat exchanger.
oIn case of prolonged power failure, one should not refill wood and stop firing.
oWhen installing the central heating wood stove and connections, follow the applicable
guidelines.
oCheck that the connection to the chimney is completely sealed.
oThe stove becomes very hot when in use.
oMake sure that no flammable materials are placed near the stove.
oThe stove door should be kept closed as much as possible. Even when not in use.
oAs far as possible, avoid overheating the stove with too much wood, which will shorten the
lifespan of the boiler wood stove.
oNever use petrol, spirit or other lighter fluids
oMake sure that the stove's air supply is not blocked.
oThe ash drawer must not be completely filled with ash. This may block the supply air. The grate
may also overheat.
oEnsure adequate air supply, aeration of the staging area
oBe aware that an exhaust hood and the same or adjoining room can cause underpressure. This
may draw flue gas from within the stove. It is important that the extractor is not used at the
same time as the boiler wood stove once an underpressure situation may arise.
oAsh should only be removed once the wood stove has cooled down completely. Ensure that the
ashes have cooled down completely before removing them.
oAlways use a heat-resistant glove when operating the stove.
oObserve minimum distances from combustible materials. These can be found in this manual.
Firing the stove
First use
When you use the wood stove for the first time, the stove has to 'fire up'. Ventilate the room well while
stoking. Make sure no cooker hood is on in the same room while the fire is burning; a cooker hood draws
off combustion air that the fire needs.
Lighting the stove
oOpen the air slider fully while lighting the stove
oFill the stove bottom with a layer of wood. Place small wood on top and make sure there is enough
kindling on top. Ignite this kindling with firelighters suitable for wood-burning stoves. Starting the fire on
top creates less creosote when the stove starts up
oLeave the door ajar so that sufficient air can enter the stove at start-up. You should stay with the stove as
long as the door is ajar.After the stove has warmed up, the door can be closed.
oWhen the stove is warm, the air slider can be retracted slightly, but the air slider should never be closed
completely!
oA single air slider stove controls both primary (combustion air) and secondary (post-combustion air) air
supply. Up to the first half you control primary air supply, the second half the secondary air supply.
Additional tips for stoking your stove
This wood stove should be fired as hot as possible to achieve good combustion. Smothering the stove
will result in poorer combustion which may lead to chimney fire. It is not allowed to close the air slider
completely.
It is not possible to keep the stove burning at night. If you add wood in the evening, it will normally burn
out after a few hours. You cannot 'keep' the stove burning overnight. A smouldering / choked combustion
leads to nothing. It only makes your chimney and your surroundings more polluted.Het is niet mogelijk
om de kachel 's-nachts door te laten branden. Indien u 's-avonds hout bijvult is dit normally burn up after
a few hours. You cannot 'hold over' the stove at night. A smouldering / choked combustion leads to
nothing. It only makes your chimney and your surroundings more polluted.
A choke valve in the chimney is not allowed.

MANUAL WOOD BOILER STOVE

Heating capacity of the stove
The actual output of the stove is largely determined by the amount of wood fired.As a rule of thumb:
1 kg of wood corresponds to 3 kW of power.
The capacity of the stove is indicated on the rating plate. This is the output that is achieved with the
prescribed amount of wood during inspection. Stoking less wood leads to less power. Stoking more
wood leads to a higher output. However, it must be taken into account that the stove does not overheat.
The capacity of the boiler wood stove is tested during the inspection and indicated on the rating plate of
the stove. Depending on the capacity, you can heat more or less. The space you can actually heat
depends on the amount of fuel, the chimney draft and the insulation level of your home. Values issued for
this reason are different in each case because not all other conditions are equal.
Correct operation
Stoves are designed to deliver maximum efficiency. A well-fired wood stove can achieve an efficiency of
around 85%. This means you need less wood for the same amount of heat. Moreover, a well-fired stove will
produce less smoke pollution.
Some tips for optimum firing pleasure:
oAlways fire your stove with the door closed.
oDo not put more than 3 logs on the fire at once. A lot of fuel at once counteracts efficient
combustion and pollutes the environment.
oVentilate the room well when your stove is burning.
oNever turn on your extractor when your stove is burning in the same room.
oFeed additional air to your wood stove only when you start firing. If you constantly supply a lot
of primary air, the efficiency will be much lower.
oDo not fire in fog or windless weather. In windless weather, there is hardly any draught in the
cold chimney. As smoke is heavier than air, there is a chance that smoke will enter the room. In
fog, the smoke from the chimney (outside) will cool quickly, drop down and cause a nuisance in
your area.
oDo not extinguish the fire suddenly with water but let it burn out. The materials inside the
fireplace may deform or crack due to sudden, large temperature differences.
Note: You control the heat output not by operating the air slider, but by the amount of wood you
fill the stove with.

Wood firing is a natural process that releases as much CO2 as during decay in the forest. However, poor
combustion can release harmful fumes. That is why it is imperative that you, the user, fire correctly to
avoid nuisance. Provide dry, clean wood and do not fire during foggy weather.Regel de hoeveelheid
warmte niet middels de luchtschuiven, maar middels de hoeveelheid hout. Het volledig knijpen van de
luchttoevoer kan een slechtere verbranding met zich meebrengen.
Checking various functions
To ensure the stove is functioning properly, it is necessary to check some parts at least annually.
Thermal temperature protection
If the temperature guard is not closed when cold but still leaks water, this is caused by overheating over
dirt that has accumulated. Once this is the case, one can press the red button of the temperature guard
several times which will flush this guard clean.
Please note that overheating and indentation of the temperature protection device may cause it to
malfunction. As a result, this part may need to be replaced.

Wood as a fuel
Only wood that is sufficiently dry, cleaved and clean is suitable for use in a Nordic Fire wood stove.
Do not use wet wood. This is wasted energy (50% less energy!) and it pollutes your stoveAND chimney,
increasing the risk of chimney fire.
Avoid nuisance. Do not fire during foggy days.
Wood suitable for stoking a wood-burning stove
It is important to use dry wood. Split wood is dry after the wood has dried in the air under a canopy for at
least 2 years, leaving a residual moisture of 15% to 19%. Oak wood should be dried for at least 5 years
before reaching these residual moisture values. We recommend not using oak or other hardwoods!
The performance of your stove strongly depends on the quality and amount of residual moisture in the
wood. The more moisture present in the wood, the more energy is required to evaporate residual
moisture.As a result, there is very little residual energy left in the wood. Wet wood is wasted energy.
Wet wood causes greater deposits in your stove and chimney. In addition, it is much more
environmentally damaging than dry wood. Firing with insufficiently dry wood leads to possible chimney
fires!
The type of wood also determines the amount of energy that can be released. Light wood types give off
the energy quickly, while hardwood gives off the energy more slowly. The following table shows the
different types of wood and their energy values.

Lighter woods burn faster and give off heat faster by reaching higher temperatures faster. Lighter woods
are therefore better suited when heating the stove. Hardwood burns slower and therefore you can stoke
longer without topping up.
A disadvantage of hardwood is that these types of wood are harder to dry. In practice, hardwood often
contains too much residual moisture. This affects the operation of the boiler wood stove. Hardwood is not
optimal for use with a central heating stove.

A few tips
oWood should be stored split.
oFirewood should be stored in a windy place, protected from rain.
oHardwood should dry longer than lighter woods
oDamp wood is wasted energy. It pollutes your chimney and causes nuisance in the surrounding
area.
Only wood that is suitable should be used in the wood stove. Never use the following types of wood:
oDamp wood, or impregnated wood/hardwood
oVarnished wood or wood with a plastic protective coating
oChipped wood
oChipboard remnants
oCoal
oWaste
oPaper and cardboard
It is important not to use your stove as a waste incinerator. Burning waste releases toxic substances.
These lodge in your chimney, but also spread into your living environment
How much wood can you fire?
Use only the amount of wood in your stove, which is necessary for the heat required at the time.
To achieve the output of your stove, you need the prescribed amount of wood. Overfilling will lead to
overheating and damage to your stove. Normally, the right amount of wood is fully burnt after about 45
minutes.
Overfilling leads to damage to the vermiculite, retaining plate and fire grate. If these parts are found to be
defective within a few years, this is due to overheating of the wood stove. This leads to additional
replacement costs.
