1.1. Document information
This document is an integral and indispensable part of the product and must be retained in good condition by the user. Keep it in a safe place for future reference.
If the appliance is sold or transferred to another person, this manual has to always follow the appliance and handed to the new user or installer.
Read the safety instructions carefully before installation. Always follow the safety instructions during installation and during maintenance
Installation, operation, service, and other work must be carried out by qualified personnel in accordance with local codes and regulations.
All electrical installation and service work shall be done by certified and qualified personnel inaccordance with local codes and regulations. Do not perform electrical work unless you have the required qualifications. Perform a complete burner shutdown and disconnect the power supply prior to performing any work on the burner. Observe all guidelines with respect to installation, service, or cleaning.
Children and adults should be alerted to the hazards of high surface temperatures and should stay away to avoid contact to skinand / or clothing.
Always follow the instructions for operations and service.
There is a risk of burn from touching the equipment during operation. The burner casing, burner body, flange, and flame trap pipe are hot surfaces during operation. Keep children away and do not touch the equipment during operation.
Young children should be carefully supervised when they are in the same room with the burner.
Electric switch must be used to the
power supply cable as an emergency stop
Only wood pellets are to be used with this burner. No other fuel is to be used in the burner.
NEVER BURN ANY TYPE OF CORN, CHERRY PITS, STICKS OR OTHER TYPES OF FUEL IN THE BURNER.
Burning wood pellets according to recommendations and the specifications set forth will assure longer burner life and lessen potential maintenance issues.
DO NOT install in a sleeping room. DO NOT connect to any air distribution duct or
system. DO NOT terminate the vent in any enclosed or semi enclosed area, such as; carports, garage, attic, crawl space, under a sun deck or porch, narrow walkway or closed area, or any location that can build up a concentration of fumes such as a stairwell, covered breezeway etc.
2. Function principle
The principle of works of MPB Pro burners is based on providing fuel via steering the feeders appropriately and the work of a fan which steers the burning process.
Burners have 3 ways of operating:
Single mode: The burner reaches the desired “HEATING WATER TEMPERATURE “(i.e 65oC) and
burns off. Then, it starts its operation again when the temperature of the boiler goes down to the temperature “HEATING WATER TEMPERATURE - CH FURNACE HYSTERESIS” (65oC - 10oC= 55oC. The CH FURNACE HYSTERESIS must be more than 10oC
Continuous mode: The burner reaches the desired “HEATING WATER TEMPERATURE “ and goes down at 3kW (maintain).When the boiler's temperature goes down to the temperature “HEATING WATER TEMPERATURE - CH FURNACE HYSTERESIS”, the burner increases its power from 3kW (maintain) to the maximum burner power (i.e30kW). The CH FURNACE HYSTERESIS must be no more than 5oC
Analogue mode: The burner reduces its power 1/3 (for example: from 30kW to 21kW) 10oC
before the furnace reaches the “HEATING WATER TEMPERATURE “. When the temperature of
the furnace is 510oC before “HEATING WATER TEMPERATURE “, the burner reduces its power again 1/3 ((for example: from 21kW to 12kW).
After reaching a particular temperature of the heating water, the driver goes into the mode of sustaining the temperature or switches the burner completely off. The ignition of fuel starts automatically with the help of igniter which is connected to this driver. The regulator operates also on the useful warm water buffer. The WUW pump starts working when the regulator detects too low temperature of the WUW buffer. It is also possible to stipulate the working mode of the WUW pump – with a priority or without it. The driver enables the control of the furnace's work thanks to the room thermostat. It is possible to steer the heating in relation to the actual temperature in the room. The regulator is also equipped with the self-control systems (detecting the malfunction of the temperature's sensors) and mechanisms monitoring the furnace's work preventing from going beyond the range of safety for the installation of the central heating.

4. Boiler
It is important to check that the combustion chamber in the boiler is big enough to ensure that the flame does not come in contact with the water-cooled walls. Verify that the boiler’s capacity range complies with the burner. There must be enough space for the ash to accumulate. The exhaust gas channels should not be so narrow that they can easily be clogged with ash.
The distance between the front edge of the burner and the rear part of the combustion chamber should be at least 350mm for the MPB 50 and500mm for the MPB 80 burner.
The minimum distance to the bottom of the fireplace depends on the boiler design.
There must be enough space for the quantity of ash build up that is created during at least one week’s use in the winter heating season.
5. Chimney
We recommend that you have a local chimney sweeper or other corresponding authority make an inspection and provide advice and instructions on the chimney measurements in accordance with local codes and regulations.
The chimney should be of a length and diameter that gives a draught of 10 - 25 Pa. Measures have to be taken if the chimney is smaller or much larger in diameter in order to give the proper draught and flow.
If there is not enough draught in the chimney, exhaust gases stack in boiler's combustion chamber or in the chimney with the risk of explosion. Also, gas flow into the boiler's room can happened.
Always check the exhaust gas temperature. Directly after the boiler it should be between 160°C and 250°C.
Too high a temperature can damage the chimney and is not economical.
Too low a temperature, a very high chimney, or a large chimney diameter creates a risk for condensation that can cause corrosion and damage due to freezing.

7. Operation functions
After switching the burner on, it is appeared on the LCD screen the program's logo defining the type of the driver and the version of the current software
While activating, the burner carries out a test of the connected sensors. In case of one lacking, on the screen appears an appropriate message (---). The work of the burner without a heating water temperature sensor (CH) is blocked and an emergency mode is activated (CH pump is still on).
Correct connection of sensors causes displaying of actual CH furnace's temperature and the temperature of useful warm water of the WUW buffer (if the function is active). On the screen appears which function is currently used by the driver.
The burner may work in three working modes (“STOP”, “IGNITION”, “AUTOMATIC WORK”). The mode changes when the “MODE/ ” button is pressed. Activating the “STOP” mode is possible in all modes after pressing the “MODE/ ” button for 3 seconds. When Stop is activated, the burner goes at “Burning off” process (if there is fire) and the at “Cleaning” process.
When the burner is activated for first time, it is on “Stop” mode. Every next time, its status is
saved in the regulator's non-volatile memory. Activating the driver again, automatically causes switching on of the lately used working mode.
In the table beneath a short description of particular functions of the burner, activated depending on the working mode of the driver, is shown.

Then, press "MODE/ " and leave the sub-menu, go to the menu "MANUFACTURER SETTINGS"
* CAUTION!!
Manufacturer's settings are exclusively the suggestion. All of the values depend on the kind of solid fuel, the sysytem, the user's requirements, etc.
The producer of the burner reserves the changes of the ranges of settings in next versions of the driver.
9.2. Description of manufacturer's settings
FEEDER FILLING TIME
In this menu the manufacturer sets the time of the feeder's filling. The time is the protection from filling up of the burner. This time depends on the angle of arrival of the large feeder. The parameter is set in the bracket of 5 to 20 minutes.
Manufacturer Advice: 10-12min
PELLETS IGNITION TIME
In this menu the manufacturer sets the time of the pellet's ignition. After the lapse of time, the ignition cycle restarts. The cycle is repeated once again. Unsuccessful trials of ignition are seen on the screen as a message: no pellets. The cause of this condition may be also a broken or dirty flame's sensor. The time of ignition is set in the bracket of 1 to 15 minutes.
Manufacturer Advice: 6-7min
FAN POWER (IGNITION)
In this parameter the producer sets the power of the fan during the pellet's ignition. The fan's power is set in the bracket of 5 to 50%. If chimney's draught is over -15Pa, then the parameter stays at 10% If chimney's draught is from 0 to -15Pa, then the parameter must change to 15-20%.
Manufacturer Advice: 15-20%
PELLETS DOSE (IGNITION)
In this parameter the manufacturer sets the dose of fuel needed to ignite the burner. The parameter is set in the bracket of 50 to 500 grams. Depending the pellet's quality the parameter can change from 150gram to 220grams. The default value is 200grams
Manufacturer Advice: 280-340gr Depends on pellet quality and on momentum the pellet comes into the burner
FEEDER PERFORMANCE
In this parameter the manufacturer sets the performance of the feeder. The whole work of the burner is based on this parameter. The parameter is set in the bracket of 5 to 45 kg/h with the step of 500grams.
Manufacturer Advise: Cannot be given any advice since it is depended on the
feeder's angle and pellet quality. Please follow the procedure on paragraph 11 “First use
PELLETS FEEDING PERIOD
In this parameter the manufacturer sets the period of feeding the pellet. After the lapse of time, the driver releases the next dose of fuel. In the cycle of maintain, the parameter is ten times multiplied. The feeding period of the pellet is set in the bracket of 10 to 60 seconds.
Manufacturer Advice: 10-20s
OVERFLOW PELLETS AIR (WORK)
In this parameter the manufacturer sets the overflow of the air needed to burn the specified amount of the pellet when the burner works at full power. This parameter should be increased if during the working cycle too low capacity of the fan would be noticed. The overflow of the air is set in the bracket from 0.2 to 2.
Manufacturer Advice: 1.0
OVERFLOW PELLETS AIR (MAINTAIN)
In this parameter the manufacturer sets the overflow of the air needed to burn the specified amount of the pellet during “Maintain” mode. This parameter should be increased if during the working cycle too low capacity of the fan would be noticed. The overflow of the air is set in the bracket from 0.2 to 2.
Manufacturer Advice: 1.0
FLAME DETECTION TRESHOLD
In this parameter the manufacturer sets the flame's detection threshold. Beneath the pre-set threshold's value, the burner detects the vanishing of the flame. The parameter is set in the bracket of 5 to 90%.
Manufacturer Advice: 10%
FURNACE PROTECTION (OVERHEAT)
In this parameter, the user sets the furnace's temperature which protects from the overheating. The protection is activated when a higher temperature than the one that was previously set is reached and when the CH pump is turned off. The driver starts the CH pump automatically and switches off the burner. The protection of the furnace from the overheating is set in the bracket of 60 to 90 ºC. The furnace's protection can be activated when:
working of room thermostat and simultaneously surpassing the protection temperature
of the furnace,
setting ”Summer” function and simultaneously surpassing the protection temperature
of the furnace,
setting the ”STOP” mode and simultaneously surpassing the protection temperature of
the furnace,
surpassing the temperature of the heating water over 90ºC.
Manufacturer Advice: 80-90ºC
STB TEMPERATURE
It is the temperature where the Overheating Alarm is activated. At the same time the controller activates the CH pump and the WUW pump. For water boiler the default value is 90oC.
If sensor type PT is chosen then, the value of this parameter can change depending the application.
IGNITION STABILIZATION
When ignition has occurred, the air-fan works for the time, which has been set by this parameter. This operation drives the ignition gases out of the boiler faster.
Manufacturer Advice: 60-120sec
MAXIMUM BURNER POWER
In this parameter the installer can set the maximum burner power, where the user can set by visiting the burner's menu. This prevents the user to set the burner at a maximum power, than the one it is required by the system. Manufacturer Advice: 50kW for MPB 50 and 80kW for MPB 80
MINIMUM BURNER POWER
In this parameter the installer can set the minimum burner power, where the user can set by visiting the burner's menu. This prevents the user to set the burner at a maximum power, than the one it is required by the system.
Manufacturer Advice: 9kW. It can be set higher, especially for industrial
applications
MINIMUM FURNACE TEMPERATURE
In this parameter the manufacturer sets the minimal temperature of the furnace which can be set by the user. The activity of the room thermostat causes the setting of the boiler into this parameter. The minimal temperature of the boiler is set in the bracket of 20 to 60 °C.
Manufacturer Advice: 35oC
SENSOR TYPE
In this parameter the installer can choose between KTY and PT 1000 temperature sensors.
KTY is the default sensor which is used for measuring temperatures up to 100oC.
The PT 1000 sensor is given by the manufacturer under request and it is used to measure temperature higher than 100oC (industrial applications).
EXTERNAL CONTROL (room thermostat)
This parameter, it is activated only if room thermostat it is connected on the controller
If external control No (Manufacturer's settings):
1. When thermostat is ON, the burner works at the maximum power is set.
2. When thermostat is OFF, the burner burns off
This is mostly suggested for low consumption houses (less than 3.000kg/year) or for connecting with timer.
If external control Yes (Manufacturer's settings):
1. When thermostat is ON, the burner works at the maximum power is set.
2. When thermostat is OFF, the burner goes at maintain mode and keeps a small fire.
In both cases, when the thermostat is OFF, the CH pump stops.
TEMPERATURE CALIBRATION
In this menu the manufacturer calibrates the temperature sensors. It is possible to add a regular offset for the temperature of the furnace and the warm useful water. The parameter is set in the bracket of -10 to +10°C.
10. First use
1. Ensure that the installation has been done according to this manual
2. Ensure that the plastic pipe is not connected to burner's feeding pipe
3. Fill the feeder up with wood-pellet, by connected the power supply cable of the controller
with the feeder's cable (alternative, you can fill the feeder by following the direction of
paragraph 14). The filling of the feeder lasts 8-13min depended on feeders incline.
4. Ensure that the feeder is full. Let the feeder working after the first pellets come out of the
feeder for 10-15 minutes (locate a plastic bag at the exit of the feeder)
5. Empty the plastic bag and place it back at the exit of the feeder.
6. Connect again the power supply cable of the controller with the feeder's cable for 2 minutes.
7. Weight the wood pellet which is in the bag (for example 0.8kg)
8. Multiply it by 30 minutes (0.8x30 = 24kg/hr). This is the feeder's performance
9. Repeat the steps 4-8, 2-3 times until you make sure that you weight the right quantity.
10. Place this value (i.e 24kg/hr) on manufacturer's settings menu, in the parameter
“5. Feeder Performance”
11. Connect the power cable back to the controller and also we plug the feeders cable to the
controller.
12. Switch on the controller and set the burner at “Automatic mode”.
13. When the maximum power of the burner is reached (from 25 to-80kW), then adjust the
burners flame by calibrating the air.
For the MPB 50, the parameter “Overflow pellet's air” at Manufacturer's menu is set at 1.0
and the burning air is calibrated by adjusting the damper of the air-fan.
For the MPB 80, the parameter “Overflow pellet's air” at Manufacturer's menu is set at 1.0
and the burning air is calibrated by adjusting the damper of the air-fan.

16. Burner safety systems
For total, fail-safe security, the burner is equipped with four safety systems:
1. The plastic pipe connecting the feeder with the burner. This tube will melt away from the burner in event of a too high temperature, thereby breaking contact between pellets fuel replenishment and the burner.
2. The burner’s fall-tube is equipped with a back-burn protection system which is triggered at 65oC. The back-fire protection system is placed on the fall-tube. In the event of the alarm being triggered always investigate the cause and rectify.
3. The Overheating Boiler sensor (STB sensor), which is activated when the boiler's temperature is higher than 95oC. When this protection is activated, the light next to the STB sensor is ON and the feeder is turned off. The, you must reset the STB sensor, the feeder to work again.
4. The photo sensor senses that ignition has taken place and is running normally.
