BOILER ROOM DESIGN:
The boiler room for biomass boilers must be performed in accordance with the Danish
Institute of Fire "Fire Standard No. 32" BTV32. In addition, you must comply with the
rules set forth by your local building codes, environmental authorities, and labor
inspectorate. If you are in doubt on how to set up your boiler room, we recommend
that you contact your local chimney sweeper for guidance.
1. Wall and Ceiling
2. Distance to the Wall
3. Floor
4. Area and Lighting
5. Chimney
6. Air
7. Water Faucet
8. Fuel
9. Prohibited Liquids and Materials in Boiler Room.
10. Permit, Notification and Inspection
1. Wall and Ceiling. Ceiling surfaces must be constructed with at least Class 1 surface material. If the ceiling surface
happens to be the underside of the roof, the material must be made of noncombustible materials. Wall surfaces must be
constructed of at least a Class 2 surface material.
2. Distance to the Wall. Distance from the boiler or flue pipe to any combustible material should be large enough of a
distance to prevent temperatures from reaching an excess of 80 ° C. This requirement applies even if the combustible
material is covered with non-flammable material. If the distance is greater than 500 mm, the distance requirement is
typically satisfied.
3. Floor. Floors should consist of (or be covered with) non-combustible material under and around the boiler of a
distance of at least 300 mm from the boiler sides, and 500 mm from the boiler’s front (i.e. the side where the ash is
removed).
4. Area and Lighting. The boiler room and area around the heating system must be large enough to allow for easy
operation, cleaning, and maintenance of the heating system and boiler room. There must be adequate lighting so that
supervision and maintenance can be performed safely.
5. Chimney. The chimney must be of a design, aperture area, and height that provides
adequate draft conditions and sufficient exiting of flue gasses. The chimney draft
is created by negative pressure resulting from the buoyancy of the hot smoke rising
up through the chimney. If there is not enough draft in the chimney, the smoke will
not properly rise and will instead seep out through small cracks. This can result in
toxic smoke seeping into the house.
6
BOILER ROOM DESIGN:
The size of the chimney opening must match the amount of flue gases the chimney has to lead away. If the
opening in the chimney is too small, this will prevent the smoke from exiting fast enough due to the large
resistance in the chimney. This could cause the smoke to turn back; thus allowing for toxic fumes to enter into
the house. Simultaneously, the pellet fuel may not be completely burned, due to the lack of oxygen for
combustion. This can cause traces of soot to sit in the chimney and create what is called shining soot, which
increases the risk of chimney fire. The chimney opening must also not be too large since cold air can enter the
chimney from the top. When the chimney becomes cooled, condensation can occur and develop soot inside the
chimney. Soot is mostly a cosmetic problem, because it can penetrate through the chimney and cause ugly brown
splotches to appear on the walls inside the house. In addition, it is important that the chimney protrudes high
enough above the roof so the smoke does not bother the surrounding houses. Environmental authorities have
the possibility of prosecuting you if there are neighbors that complain about the smoke or odor.
What signs are there, if the chimney is not working?
• Light sensor is sooty or melted.
• Smoke in the hopper.
• Warm drop shaft.
• Smoke billows out of the fan or boiler during startup.
If you have any problems with your chimney, it is a good idea to keep a "diary“
of any draft problem; as draft problems are often associated with wind in certain
directions. Wind blowing on one side of the house can cause under pressure on
the other side of the house. Overpressure and under pressure will try to balance
out even through a chimney, if possible. It is a good idea to ask your chimney
sweeper about the size of the chimney and flues, the location of chimney
cleaning doors, and whether it is required to have steps on the roof. He will also
perform a fire prevention inspection
6. Air. The pellet boiler should be supplied with enough air for combustion. This
can be achieved if the pellet boiler is installed in a room which is equipped with a
sliding window with an adjustment bracket, an adjustable air vent from the outside,
or by providing the combustion chamber with air through a duct from the outside.
The area size of the fresh air valve should generally be the same as the internal diameter of the chimney. It
should also be mounted on the same side as the chimney to compensate for any pressure differences.
Note: drum dryers, range hoods, oil burner in the same room, all use high pressure blowers, that steal the air in
the room!
7. Water tap. There must be a tap in the boiler room. If the boiler output is less than
60 kW, a powder extinguisher (at least 5 kg) will suffice.
7
BOILER ROOM DESIGN:
8. Wood Pellets. The pellets must consist of pure wood, 6-8 mm max 8% water. Materials with glue, paint, wood
paint or plastics must not be burned. If the fuel storage is greater than 0.75 m3, the boiler system and fuel storage
must be located in a separate fire cell with at least one BD30 door to the other room. If the fuel storage or hopper
is placed in the open or under a shelter, there may be minimum distance to the building that should be observed.
Exposed fuel may not be in the boiler room, except logs. Do not exceed 4.75 m3 fuel in the boiler room, including
fuel storage and usage storage
9. Prohibited liquids and materials in boiler room. The boiler room must be kept clean and contain no combustible
materials nor flammable liquids (except oil for oil burners). The floor must be kept free of spilled fuel, dust and
combustible waste as well as waste from other activities in the room. Any burning embers
must be extinguished with water and transported to a secure storage location in the open.
!
10. Permit, notification and inspection.
Building permit:
You must obtain a building permit if the burner is situated in a building that is part of the Building Regulations 1995
(commercial buildings); though not for animals and farm buildings
Notification:
The heating system must be reported to the local council and registered with the chimney sweep.
Inspection:
The chimney sweeper will regularly supervise your biofuel boiler. If the chimney sweeper becomes aware of any
illegality under the rules for fireplaces and chimneys in the building code, he may notify the local council if the
owner does not change the illegal conduct.
Insurance:
You must notify your insurance company about your biomass system.

INSTALLATION OF THE
BOILER:
A correctly executed installation ensures that the system functions properly.
Both national/local guidelines and requirements must always be observed.
The boiler can be installed on a pressurized system up to max 2.5 bar.
1. Standard.
DHW with mechanical flow control
2. DHW with 2 way valve.
Typically used when DHW is small or
when the surface coil is small.
Heat for the house is supplied while hot
water is being produced.
3. DHW with 3 way valve.
-Typically used when the water heater is large,
and when the surface coil is large
-The house is not supplied with heat while
producing hot water. The house must therefore
be able to manage without heat for short periods
during the winter .
4. Weather compensation.
Allows you to have a high temperature on the boiler.
Manage the supply temperature to the house in
relationship to the outside temperature and chill factor.
5. Weather compensation and solar heating
Do not go down on equipment 
10
INSTALLATION OF THE
BURNER:
General Guidelines:
Installing the burner on the boiler:
1. Check that the burner is not damaged during transport.
2. Check that the burning grate is inserted correctly in the burner (see image right).
3. Mount the burner and tighten the burner with the 2 wing nuts supplied.
Never use locknuts, as the seal between the boiler and the burner can leak over time.
4. Make sure that the burner is horizontal and that all connections are tight.
5. Mount the shield and the connector on the burner.
6. Install electricity for safety cut-off thermostat according to the wiring diagram. SAFETY THERMOSAT
MUST ALWAYS BE FUNCTION TESTED! The thermostat can be tested by using an electric kettle. The
thermostat must switch off when the temperature feeler is dipped into boiling water. If necessary, adjust
the switch-off temperature lower by turning the screw inward. Reset the thermostat by pressing hard on
the red button!
External auger:
7. Install the auger output over the burner.
8. Auger should be at an angle between 0 and 50 degrees.
9. The flexible hose should be angled enough as to allow for the free passage
of the wood pellets to the burner without getting stuck in the PVC hose.
11
INSTALLATION OF THE
BURNER:
Temperature sensor on the boiler:
Mount the sensor within a sufficiently long thermo well.
Use a fastening strip or similar to prevent accidental slippage.
Safety thermostat:
Mount on either the left or right side of the boiler as
displayed in image.
Note: Functional testing of the high limit safety thermostat
is required before starting up the boiler.
To test, press moderately on the disc (shown in A) in the
direction towards the temperature feeler. A small "click“
will occur, signaling that the connection between C and C2
is interrupted and that the high limit safety thermostat is
triggered. To re-activate the thermostat, press hard on the
red button marked (B) in the drawing. You will also hear
a "click", signaling that the connection between C, and C2
is restored and that the high limit safety thermostat is
activated and ready for use.
Semi cleaning on BS1016, BS2030 and BS4050:
The boiler cleaning system must be connected with 230V AC
through the socket located on the back of the boiler. In the
control box, make a connection to output (L5-L10). The cleaning
system will run every time the burner conducts a blower
cleaning sequence, ie. typically 5 sec. every 10 min. These
settings can be configured under the Cleaning menu in the
controller.

NBE's Cloud Service ensures:
Fewest possible number of electrical ignitions.
Best possible PI regulation.
An optimized system for your house.
Lower wood pellet consumption.
Security in everyday life.
The latest updates to the controller.
22
FIRST TIME START UP:
Once the system is assembled, filled with water, and power is connected to the system a
few basic adjustments to the burner is required.
1.
Fill the auger with pellets by force starting the auger either through the
controller or directly via a 230V connection.
2.
When the augur appears full, run for an additional 15 min. to ensure
correct weighing later.
3.
Activate the 6 min. test run in the controller and collect the dispensed
pellets with a plastic bag.
4.
Using a kitchen scale, weigh the pellets from the test run and enter the amount into the controller under
"Auto calculation“. Repeat again after 7 days!
5.
Adjust minimum output as low as possible, typically 10% of the burner's rated output (i.e. if 20kW, set to
2.00kW). If the chimney draft is high, adjust the minimum output up until you have a stable flame at 10%
power.
6.
Once the burner is activated an ignition will be made. After approx. 20 minutes the burner will reach a nominal output
(100%). If necessary lock the burner output at 100%. Now you can perform an evaluation as to whether the fan is providing
suitable supply of air to the flame. If necessary, adjust in the fan menu
The flame at 100% should fill the entire width of the grate,
have redish spikes, and reach the opposite wall…
7.
Lock the burner to 50% power. Wait 5 minutes for the flame to stabilize.
Again, assess fan performance in relation to the flame
The flame at 50% should be approx. 10 cm out of the burner
and is yellowish in color.
8.
Lock the burner to 10% power. Wait 5 minutes for the flame to stabilize.
Assess fan performance in relationship to the flame.
The flame at 10% should be small and short
The photo sensor reading may fluctuate, however, it should not have a 0 LUX
reading for a period >10 sec. If the chimney draft is too high, increase the
minimum effect of the burner to increase flame size.
23
CLEANING THE
BURNER/BOILER:
Cleaning should be carried out regularly and/or as needed. There is a big difference in the
frequency of maintenance required from system to system. The setup, adjustment, and
wood pellet quality play an important role on how frequent maintenance should be
performed.

Turn off the burner in connection with cleaning.
Turn off the controller and allow to cool for approx. 5 min. Once the burner is completely turned off, it is ready for cleaning.
Unplug the burner, remove the shield, drop shaft, and detach the burner from the boiler so work can be easily performed.
Boiler.
All surfaces inside the boiler must be brushed clean from any deposits and the ash can must be emptied. When empting the
ash can, pay special attention to any build-up of ash in the rear smoke chamber and flue, since the Chimney Sweeper may not
always be removing the ash from the chimney flue
Never dispose of hot ashes in the trash, but let it cool in a metal bucket. Hot ashes can start burning when
it gets oxygen (air).
!
Burner head.
Remove any ash or cinders from the grate. Remove any pellet remnants under the burner grate. Wipe the photo sensor clean.
When re-inserting the photo sensor, ensure that the sensor points towards the combustion grate. Ensure that there is nothing
lodged in the fan and that it can rotate freely.
Hopper.
Since pellets naturally contain dust, you should periodically empty the hopper completely. The more dust that is present in
the hopper, the less the auger will dispense, and the more unstable the dosing. The boiler will go out of adjustment with
greater risk of downtime. How often one should empty the hopper depends greatly on the design and quality of the pellets
you use.
!
Put 1 dl cooking oil or similar into the hopper each time it is emptied (poured over the last pellets)
and the hopper will automatically empty the sawdust.
Start-up after cleaning.
Once the pellet boiler is reassembled, turn on the controller and the burner will start itself up.
!
Remember to reattach the shield so that the temperature reading on the burner is correct

FLUE GAS
CONDENSATION:
When a boiler has an extremely high efficiency (for example > 93%), the flue gas temperatures exiting the
boiler are very low. As a consequence of this high efficiency and low chimney temperature relationship, proper
precautions must be observed to avoid condensation from developing in the chimney. Leaving condensation
untreated will risk the development of soot in the chimney, corrosion in your boiler, as well as possible loss of
warranty.
Note: even if there is water in the boiler it may be due to condensation in the chimney.
Things that can prevent condensation in the boiler and chimney.
1. High chimney> 5m.
Provides a good draft in all conditions.
2. Small clearing in the chimney 125mm-150mm.
Provides better flow, and can "carry“ out more moisture.
3. Short un-insulated smoke pipe 70C degrees.
10 degrees up in the boiler temperature gives 10 degrees more smoke temperature.
6. Suitable return temperature> 55C degrees.
Hits the smoke boiler surfaces under 47C degrees, it starts condensing.
7. Open bypass in the boiler.
Release the smoke before the last smoke cooler, 15C degrees increase in
temperature of the smoke, only costs approx. 1% in efficiency.
8. Heated boiler room.
Lowers cooling of the boiler and smoke pipe and provides draft stabilizer more hot
air to work with.
9. More oxygen in combustion.
Increases air flow in the boiler, and carries more moisture, 1% more oxygen costs
approx. 0.5% in efficiency.
10. Remove the retarder.
The retarder decreases resistance of the boiler, and get a bad chimney to work
better. The gas temperature typically increases to approx. 100 degrees. The burner
should be basic readjusted after retarder is removed.
11. Keep the heat on the boiler continuously.
When using DHW priority on controller, and the boiler starts from cold each time it
starts The boiler is not to dried out between each start.
12. Mount electric exhaust fan to chimney.
Helps the flow the right way, from CHIP 6.82 can exhaust fan be connected directly
to the controller.
