01 General Information

Our customer service or an authorized specialist contractor must carry out assembly, installation, and initial start-up

(setting) of our pellet heating system.

Recommendation: For long burner running times, in order to reduce the start-stop emissions and to reduce maintenance costs, the boiler should be fitted with a buffer storage tank, thermosiphon buffer storage tank or combination storage tank. In practice, buffer capacities between 40 and 75 litres/kW have proven successful. Be sure to take into account the country-specific requirements regarding buffer storage tanks. The operation of the system is only permissible if it can be guaranteed that the boiler‘s nominal heat output can be reduced by 50% for a period of at least 2 hours.

Use only those fuels recommended by us - wood pellets pursuant to EN 14961-2, Class A1+ A2 (Ø 6 mm). Only in this way can low-emission, economic, and trouble-free operation of your pellet heating system be ensured. Non-compliance will result in voiding of the guarantee.

At regular intervals, perform the maintenance and cleaning procedures recommended by us in the manual for your pellet heating system. When this is done you not only ensure the functional reliability of the system and its safety systems, but also efficient, low-emission operation of the system. You achieve the best care of your pellet heating system by concluding a maintenance contract. The indicated cleaning and maintenance intervals must be unconditionally respected. Please note that, no warranty claim arises for damage that is the result of non-compliance with the maintenance instructions.

Your heating boiler is adjustable within an output range of 30% to 100% of the rated output. The units should be

operated if at all possible in the middle and upper output range (adjusted to the respective heat requirement), in order to avoid unnecessary emissions in low load operation. The ideal is the combination with a modulating room and heating regulator in order to avoid unnecessary cycles and to enable the longest possible running times.

If technical changes are undertaken independently, we assume no liability for damages that that may result thereof.

Any procedure undertaken by persons other than those authorized by us, and non-compliance with these general considerations and the safety notices described below, shall result in immediate voiding of any warranty claim as well as the guarantee.

Damaged parts and unit components must be replaced only with original replacement parts.

It is urgently recommended that this manual be kept within reach in the heating room.

The pellet heating system described in this manual has been tested in accordance with EN303-5.

The generally applicable rules of heating technology must be observed for protection against Legionella.

NOTE: When using pellet heating systems with 2 suction turbines (e.g. 100kW boiler) the daily tank is unequally emptied (complete emptying cannot be ensured). We have already recommended in the planning a division of the storage area of between 60 and 40%.

The mandatory maintenance of the system must be done by authorized technicians at least one a year but no later than when reaching 1500 hours of operation (with an output range of 80-100%).

If NO service is performed, the warranty claim or the warranty is void!

In the course of maintenance work on the pellet heating system all wear parts are replaced and billed, if necessary.

For service work to be performed, the system must be „cold“. If the system is not shut down in sufficient time and is still

“warm” when the service technician arrives, the resulting idle and waiting time will also be billed.

Foreign bodies in the fuel can result in damage to the system.

The regulations pursuant to A-Norm M 7136 (Transport and Storage Logistics) and M 7137 (Pellet Storage Requirement) must be observed.

Please note that you must observe the prescribed servicing intervals during the warranty period!

Properties that require a high degree of security for heat supply (the hotel business, process heating, etc.) are to be equipped with dual boiler systems. If this requirement is not met, we will deny any claims for consequential damage based on a faulty heating source. In a biomass heating system, it is essential to take appropriate care ( caretaker, porter, etc.) so that the stipulated maintenance tasks are carried out regularly!

We assume warranty obligations in accordance with the provisions of our warrantee conditions only when original Biotech replacement parts are used. Biotech grants repair service and supply of replacement parts for at least 10 years from the date of purchase of the system!

02 Safety Notes

A heating emergency switch (all-phase multidirectional switch off) must be arranged upstream of the combustion chamber! Switch it off before carrying out the maintenance and/or service work!

The safety notes must absolutely be read before operating the system! Non-compliance with the safety notes can result in physical injury, life-threatening situations, or damage to the system!

• The pellet heating system may be operated only in technically perfect condition. Malfunctions and damage that adversely affect or are capable of adversely affecting safety, must be resolved promptly by our technical personnel.

• Assembly must be done only by our customer service or by an authorized technical contractor . The system includes rotating parts that are driven at relatively high torque (crushing hazard).

• Live voltage parts are located under the enclosure and in the junction boxes. Therefore never remove enclosure parts or never open the junction boxes!

• During running operation never open the maintenance ports of the boiler; hot flue gas and dust can escape.

The system must be switched off prior to carrying out any maintenance. Use the ON/OFF switch to switch off the system. Wait until the system is cooled down (please refer to the boiler temperature on the display). Then switch the system off using the Heating Emergency OFF Switch. Secure the switch against accidental switch-on of the system.

Before sweeping the heating tube or the chimney by the chimney cleaner, switch off the system using the ON/

OFFswitch and wait for the burn-out process (about 20 minutes). Explosion hazard due to flue gas congestion.

• Never empty flammable liquid into the combustion chamber.

• Never perform repair work yourself on our systems but rely on our technical personnel. A warning sign „Smoking and tampering with open flame and fire is prohibited“ must be posted (hazard when refilling the pellet hopper).

• A certified fire extinguisher must be provided in the heating room.

Ensure an adequate supply of fresh air.

• Secure the heating room against unauthorized access, especially by children.

• The boiler doors and the water-side connections must be inspected once a month for tightness and damage.

• The safety temperature limiter (STL) must be inspected once a year (this should be done during maintenance or service).

• Safety and monitoring devices must not be removed, bypassed or in any other way made inoperative.

• When cleaning and when removing ashes use a dust mask in order to prevent hazards to health and damages.

• When filling the fuel bunker using pump vehicles, the system must be switched off (waiting time: 20 minutes).

• When setting the non-potable water temperature above 60 ºC ensure an appropriate mixture of cold water (scalding hazard).

6

• The pellet heating unit must be set up and operated only in heating or installation spaces that have been constructed in accordance with regulations.

• A suitable vent valve must be installed on the top of the boiler.

• The heating system must be filled with heating water in accordance with VDI 2035 or A-Norm H 5195-1.

• Annual inspection of the heating water pursuant to A-Norm H 5195-1.

• Annual inspection of the safety valves by a specialist.

• Regular inspection of the expansion daily tank by a specialist.

• Regular inspection in accordance with prTRVB H 118 of the discharge device, automatic wood firing systems, loader.

• Fire prevention specifications that are compliant with the applicable regulatory provisions must be implemented!

Please note that even when the system is switched off, different functions are still operating! (The frost protection device, pumps, and mixers are moved periodically during night times in order to prevent sticking of the bearings).

In order to be certain that absolutely no current is still flowing through the system, you must disconnect your heating unit from the mains!

• The manufacturer assumes no liability for damage arising from an incorrect hook-up of the flow and return – do not confuse these connections. Establish removable and non-distorted connections. When routing pipelines ensure venting of the boiler block. For the event of repair, equip the system at the appropriate point with shut-off devices (e.g. ball valve etc.).

• Before hooking up the boiler to the heat distribution system: Flush the lines and remove residues.

• Caution: Danger of injury by safety valve blow-off! Direct blow-out water to the drainage point.

• Check the boiler for leaks prior to initial start-up. Pressure test the boiler using the pressure equivalent to the safety valve response pressure. Large pressure will damage the pressure, control, and safety devices. Carryout closure integrity tests in accordance with local regulations.

• Fill the boiler only when it is in a cold condition The flow temperature must not exceed 40°C

03 Return water riser

It must be ensured that the return temperature never drops below 55 °C. Since this is not possible without an automatic return water riser, installation of the device is compulsory.

Disregard voids the warranty.

07 Refilling of the pellet storage

7.1 Fuel

The wood pellet boiler is designed for burning wood pellets according to Ö-Norm and DIN-Plus SWISSPELLET. By using other qualities of wood pellets, the consistent functioning of the pellet boiler cannot be granted. Failures that are caused by the use of different fuels will not be covered by warranty.

7.2 Pellet loading

While filling the pellet storage or underground tank, observe strictly the following instructions:

• Switch off the pellet boiler approx. 20 minutes before starting the filling operation in order to ensure that the flame inside the pellet boiler has completely extinguished.

• After re-filling the pellet storage, restart the pellet boiler.

• Pellet feeding by worm screw:

Remove possible excessive deposit of dust around the suction zone.

(Inform your pellet supplier or technical service or qualified re-seller).

Make sure that the worm screw is not feeding an excessive quantity of wood dust during the refilling of the pellet storage.

11 Operation modes

The current operation mode is displayed with the white bar.

11.1 Domestic hot water tank operation mode

Operation mode for the preparation of domestic hot water.

The pellet boiler only starts at the pre-set loading times (see production of domestic hot water).The heating circuit is not activated, even if the temperature falls below the summer / winter switching temperature. The domestic hot water tank pump only starts when the pellet boiler temperature reaches 55°C.

11.2 Automatic operation mode

Can only be selected in combination with a heating circuit regulation controlled by the external weather compensation (outside temperature).

In automatic mode, the domestic hot water tank and the heating are activated together. If there is no heating demand from the heating circuit controlled by the outside temperature, the pellet boiler automatically switches to SUMMER

MODE (domestic hot water tank mode) and switches back automatically to WINTER MODE (automatic mode) as soon as the heating is required again.

The switch over is the result of an automatic calculation (based on mixer setting) or of the average daily temperature.

The pellet boiler switches to domestic hot water operation mode if no „+“ order arrives from the mixer in 60 minutes.

The boiler is not kept on standby temperature anymore and as soon as the mixer demands heat, the pellet boiler restarts, as long as the boiler has reached the switch on temperature set in the hysteresis.

e.g.: Boiler SET:

Hysteresis:

Switch on temperature:

70°C

15°C

55°C

11.3 Buffer operation mode

Buffer operation mode is used in combination with a buffer. Choose this operation mode if the buffer control is controlled via the pellet boiler. Make sure that the buffer probes are mounted correctly

Buffer switch-on temperature = top probe

Buffer switch-off temperature = bottom probe

The buffer pump starts at a pellet boiler temperature of 56°C.

With buffer priority „ON“, the domestic hot water tank is loaded via the buffer.

With buffer priority „OFF“, the domestic hot water tank is loaded via the pellet boiler.

If the domestic hot water tank demand is activated and the buffer is cold first, the buffer is loaded until its temperature is

5°C above the set temperature of the domestic hot water tank.

18

11.4 Time operation mode

This operation mode is mostly used when no automatic heating circuit regulation is available.

The pellet boiler only starts at preset times.The domestic hot water tank loads at preset loading times even if these are different to the programmed heating times.

If the boiler is controlled using an external input then the boiler should be set to time operation mode and the time window set to 24 hour operation e.g.: from 05:00 to 04:59

11.5 Switching between operation modes

• Press until you reach the main menu

• Press until the white bar highlights the operation mode

• Press (submenu operation mode appears on the monitor)

• Press until the white bar is on the target operation mode

Press (the operation mode is now selected and the control switches automatically back to the main menu)

Heating circuits controlled by the outside temperature

(max. 4 mixer circuits)

15.1 General Explanation

The integrated heating regulation („climatic“) adjusts the flow water temperature according to the outside temperature and the pre-set hysteresis temperature curve.

It is possible to reduce tthe flow temperature in the night or during the day

(e.g. if nobody is at home during the day).

It is possible to set two time intervals of reduced temperature a day depending on individual customer needs.

You can determinate the value of the temperature reduction according to your personal needs.

TIME

DAY

NIGHT

Available operation modes ●Time / Day / Night

The control works according to the preset heating times and reduced temperature times

The control does not consider the set times and temperature reduction values but works according to the heating curve, without reducing the temperature (suitable setting for very slow heating systems)

The control only works according to the preset reduced temperature (if you are not at home for several days and wish however to ensure a minimum temperature)

Available operation modes ● External / Fixed / Off

EXTERNAL The control works according to the outside temperature

FIXED

OFF

It is possible to set a fixed temperature of the flow water. The control will maintain this temperature, independently from the outside temperature, day, night or time setting.

The climatic regulation is turned off
