2.2 Permitted uses

The boiler should only be operated when it is in full working order.
It should be operated in accordance with the instructions, observing
safety precautions, and you should ensure you are aware of the
potential hazards. Ensure that any faults, which might impact safety are
traced and removed immediately.

The P2 Pellet Boiler is intended exclusively for heating up
heating water. Use only the fuels specified in 2.2.1 below.

The manufacturer or supplier is not liable for any damages
resulting from non-permitted uses.

2.2.1 Permitted fuel

Wood pellets from natural wood with a diameter of 6mm

Applicable standards:

Austria: ÖNORM M 7135 - HP 1 and/or DINplus certification

program

Germany: DIN 51731 - HP 5, DINplus certification program and/or

ÖNORM M 7135 - HP 1

Applies generally:

Before refilling the store, check for pellet dust and clean if necessary.

Non-permitted fuels!

Burning non-permitted fuels lead to a build-up of aggressive
sedimentation and condensation, which can lead to damage to the
boiler and also voids the warranty!

2.2.2 Who can operate the boiler

Only trained operators are permitted to operate the boiler.

No unauthorized access to the boiler room.

Danger: Personal injury and damage to property.

It is the responsibility of the operator to ensure that unauthorized persons,

2.3 Design Information

It is generally forbidden to carry modifications to the boiler or to change
or deactivate safety equipment.

In addition to the operating instructions and the applicable regulations
for the country in which the boiler will be operated for installation and
operation of the boiler system, all fire, police, and electrical regulations
must be observed.

2.3.1 Official approval and obligation to report

Each heating system must be officially approved.

When installing or modifying a heating system, you must inform the
inspectors from the supervisory authority and get authorisation from the
building authorities.

Austria: Report to the construction authorities of the community or

magistrate

Germany: Report new installations to an approved chimney sweeper and to

the building authorities.

2.3.2 Requirements for heating water

The requirements for heating water are based on the following
standards:

Applicable standards:

Austria: ÖNORM H 5195-1
Germany: VDI 2035

If the system is topped up or refilled:
Prepare (soften) the water to prevent boiler scaling.

2.3.3 Ventilating the Boiler Room

The openings for the supply air and the exhaust air should be arranged
as nearly opposite each other as possible to achieve a good thermal
draught effect.

 The supply air must be drawn in directly from outside. The exhaust

air must be discharged directly outside.

Provided they are not contradicted by the relevant building regulations
room where the boiler is to be installed, the following standards apply:

2

Rule of thumb:
Provide a supply air cross-section of 2 cm2 per kW of boiler rated output,

as per ÖNORM H 5170, but a total cross-section of at least 200 cm

2

2.3.4 Heating System Installation/ Standards

The following standards govern the installation of heating systems:

Applicable standards:

ÖNORM / DIN EN 12828 Heating Systems in Buildings

The following prior standards still apply:
Austria: - Closed systems as per ÖNORM B 8131

- open systems as per ÖNORM B 8130
Germany: - closed systems as per DIN 4751 Part 2

- open systems as per DIN 4751 Part 1

A storage tank with the proper dimensions will guarantee the best boiler
operating values during the entire heating period.

Return feed lift

If the heated water return feed is under the minimum return
temperature, a portion of the heated water outfeed will be mixed in.

Below dew point / condensation forms during operation without
return feed lift!

Condensation water and fuel residue combine to form an aggressive
condensate, leading to damage to the boiler!

Regulations demand the use of a return feed lift!

§

Safety

Design Information

2.3.5 Chimney connection / chimney system

The standard EN 303-5 specifies that the entire flue gas system must be
designed to prevent, wherever possible, damage caused by seepage,
insufficient feed pressure and condensation.

It should be noted here that flue gas temperatures of less than 160 K
above room temperature can occur within the permitted operating range
of the boiler.

The flue gas temperatures (when cleaned) and the additional flue gas
values can be found in the technical specification sheets.

 Page 12, Boiler data for constructing the flue gas system

Install the connection to the chimney via the shortest path, as far as
possible under 30 – 45°. Insulate the connector.

The entire flue gas system (chimney and connection) must be worked
out as per ÖNORM / DIN EN 13384-1 or prior standards ÖNORM M
7515 / DIN 4705-1.

In addition, local and other legal regulations apply!
 The chimney must be approved by a smoke trap sweeper or

chimney sweeper.

 As per TRVB H 118 (only in Austria) an explosion flap must be

installed in the flue pipe or in the chimney.

Draught limiter

 We recommend that you install a draught limiter 1
 Install the draught limiter directly under the mouth of the flue line,

as there is always low pressure there.

4.2.1 Modes

Winter operation The boiler controls the heating and hot water heating according to the timed

program settings. There is no reduction in temperature  the boiler stays at
the same temperature and maintains a constant burn.

Summer operation

Systems without storage

The boiler only controls the hot water heating according to the timed program
settings. There is no reduction in performance  the boiler switches to “Burner
Off”.

Summer operation

Systems with stores

The boiler regulates domestic hot water (DHW) heating according to the DHW
tank loading times, which have been set. After heating the domestic hot water,
the boiler switches to “Burner Off”.

Transitional operation

Systems without storage

The boiler produces heat during the specified heating phases (“Boiler times”
menu). Heating and hot water are regulated according to the specified times
(heating times, DHW tank loading times). There is no reduction in temperature
 the boiler stays at the same temperature and maintains a constant burn.
When the heating phase ends, the boiler switches to “Burner Off”.

Transitional operation

Systems with stores

If the temperature falls below the “Store up min. temp.”, the boiler is turned on
within the specified store loading times. If the store is fully loaded, the boiler
switches to “Burner Off”. When the parameter “End of 1st or 2nd store loading”
is reached, the boiler also switches to “Burner Off”, even if the store is not fully
loaded.

NOTE: Set a sufficiently large time window (00:00 to 24:00 means that as soon
as the value falls below the parameter “Storage up min” the store is
immediately fully loaded)

NOTE: This is an ideal operating method for systems with storage tanks

Extra heating

Press and hold the key for 5 seconds:
The controls are set to “Override”: the boiler switches on for 4 hours; hot water

heating and heating circuit regulation are active.

Firewood operation This mode is for emergency firewood operation. The pellet feeding system is

deactivated.

Cleaning The boiler turns off the combustion system as directed (“Burner Off” status)

Then the ID fan, combustion air fan, heat-exchanger system and ash screw are
controlled according to the program.

After the cleaning has finished, reset to original mode.

Chimney sweeper

Press and hold the key and the

BACK

key for 5 seconds

The chimney sweeper program for boiler measurement is started.
The system is operated for 30 minutes at nominal load. For this aim the
maximum boiler temperature, the maximum heating circuit flow temperature
and the DHW tank loading are released.

Switched off

Press the key
The boiler turns off following the shutdown routine. The system now only

regulates the connected heating components

For systems with a storage tank, always select transitional operation!

4.2.2 Operating statuses

Preparation The induced draught fan is switched on.

Heating up The combustion bowl is filled with pellets. The supply air fan, the induced

draught fan and the igniter are turned on.

Pre-heating The pellets are pre-warmed with the fan-assisted ignition and a bed of embers

is formed. No fuel slide-in unit.

Ignition The pellets are ignited with the fan-assisted ignition. The flame is spread across

the whole combustion bowl. The supply air fan, the ID fan, and the slide-in unit
can be set in the “Ignition” menu.

Heating The Lambdatronic controls combustion according to the target boiler values.

Constant burn The boiler has reached the specified temperature and there is no reduction in

temperature. The supply air fan, the ID fan, and the slide-in unit are
deactivated.

STBY. Wait 1 The supply air fan and perhaps the ID fan are running too slowly (“Fan during

shut down”) to burn the remaining pellets. No slide-in.

STBY. Feed 1 Safety slide-in after the first wait time. As with status “STBY. Wait 1”, but

with slide-in, in accordance with the parameter, “Feed off”.

STBY. Wait 2 The supply air blower fan and the induced draught are switched off, no slide-in.

STBY. Feed 2 Safety slide-in after the second wait time. As with status “STBY. Wait 2”, but

with slide-in, in accordance with the parameter, “Feed off”.

Fault ATTENTION - Fault!

Error correction 20 min When the faults “Ignition failed”, “Safety time elapsed too low”, “Safety time

O2 too high” and “Pressure monitor comb chamb” are acknowledged, error
correction starts. When error correction has been carried out (approx. 20 min)
the warning, “Clean/ check burner”, is shown on the display. The warning can
only be acknowledged with the enter key after checking the burner.

Burner Off

This status is reached by pressing the key when store or DHW tank loading
has finished, or after acknowledging an error message, which requires a
shutdown. All parts of the boiler stop. The system now only regulates the
connected heating components.

6.1.1 System procedure following power failure

When the power supply has been restored the boiler returns to the
previously specified mode and is controlled according to the specified
program.

EXCEPTION:

If the boiler was at operating status “Heating up”, “Pre-heating” or
“Ignition” troubleshooting is started automatically. When error
correction has been carried out (approx. 20 min) the warning, “Clean/
check burner”, is shown on the display. The warning can only be
acknowledged after checking the burner.

6.2 Excessive temperature

The safety temperature limiter shuts down the boiler when it reaches a
temperature of approx. 100°C. After the boiler has cooled down, the
safety temperature limiter (1) must be manually unlocked:

 Unscrew the cap on the safety temperature limiter
 Reset the safety temperature limiter by pressing with a screw-driver.

7.3.5 Boiler Release

When setting the system selection, the parameter “Boilerlaunch in av” is
preset to enable an external floating release or start contact.

Boilerlaunch in av YES

This is set if boiler release input is available.
As long as the contact is closed, the controls operate

according to the specified parameters. If the external
contact is open, the boiler loses the release and
follows the shutdown procedure.

(e.g. flue gas thermostat of a supply boiler)

Boilerlaunch in av NO

This is set if there is a boiler start input or no layout.
As long as the contact is open, the controls operate
according to the specified parameters. If the external
contact is closed, starts the boiler and works in
continuous operation. (e.g. heat requirements of a
heating fan)

 If the boiler is released or started by the parameter, it goes at least

to “Heating” status, even if meanwhile the signal has stopped.
When this has been carried out, the boiler follows the shutdown
procedure.

 Note: Do not set any wire handle  Continuous operation!

NOTE for Uno/Eco/Komfort universal suction systems and bag silo
systems:

To fill the suction unit container set the “Fill” parameter in the “Manual
operation” menu to “ON”. The suction system starts and the suction unit
container is filled with fuel until the switch point of the level sensor is
reached.

NOTE for screw suction systems, underground tank (external
discharge):

To fill the suction unit container, set the “Start of automatic filling” in
the “Outfeed” menu to one minute after the current time. This starts the
suction system a minute later and the suction unit container is filled with
fuel until the switch point of the level sensor is reached. After filling,
reset the parameters to the desired time.

7.4.6 Setting parameters

After starting the boiler with the key, “Winter operation” mode is set
according to factory settings.

 For other modes see 4.2.1 Modes

You need to check and if necessary adjust the following parameter:

Heating curve Radiator or floor heating
Minimum flue gas

temperature

The value should be adjusted for chimneys without
tiles or a stainless steel pipe.

Mode

 See 4.2.1 Modes

Induced draught offset Settings are made by the service technician using

an analytical device

The other parameters are factory set in such a way that in most cases
optimal operation is possible without making further changes to the
parameters.

The following parameters, however, can/should be adjusted as desired
by the customer:

- Target boiler temperature

- Storage times

- DHW tank times

- Solar parameters

- Reduction programs

- Heating circuits 1 - 4

- Start of automatic filling (for suction systems)

- Boiler times (only for transitional operation)
