Any specific precautions that shall be taken when the solid fuel boiler

is assembled, installed or maintained

Each time before installation, start-up or maintenance of the

device, the recommendations contained in the Operating

Manual provided by the manufacturer should be taken into

account

Fuel gasification boiler: wood. Protected by patent application no. P.437844 and P.444656.

1. General information

The operating manual for the boiler is an integral part of the product and must be handed over to the user also in case

of transfer of ownership. Please read it carefully and keep it for future reference as the information regarding, among

other things, installation, operation, maintenance, safe use, if necessary, can provide appropriate guidance.

The installation of the boiler must be carried out in accordance with the standards and regulations of the country of

destination, according to the manufacturer's instructions and by trained and qualified personnel. Improper installation of

the boiler may cause injuries to people and animals and damage to property for which the manufacturer is not

responsible. The boiler may only be used for the purpose for which it was specifically designed. Any other use of the

boiler must be considered inappropriate and consequently dangerous.

In the event of errors during installation, operation or maintenance caused by failure to comply with the applicable

legislation, regulations or information contained in this manual, the manufacturer waives any contractual or extra-

contractual liability for the damage caused, and the guarantee relating to the appliance becomes null and void.

NOTE!

Please be advised that any unauthorised modifications to the appliance aimed at adapting the boiler to

carry out functions not provided for by the Manufacturer, including combustion processes and the use of

fuels other than those specified by the Manufacturer in this Operating Manual, are strictly prohibited and

constitute grounds for the loss of the guarantee for the appliance.

NOTE!

Boilers meeting the 5th class and ECODESIGN requirements are characterised by a low flue gas

temperature. Operation of such a boiler at a return water temperature lower than 55°C leads to

accelerated corrosion of the boiler exchanger. It is necessary to install a system increasing the return water

temperature, ensuring a temperature of at least 55°C. This is a prerequisite for the efficient operation of

the boiler and the recognition of warranty claims on the integrity of the heat exchanger.

2. Application of the boiler

Low-temperature water boilers for solid fuels with manual feed, type MPM Wood Plus are designed for operation in

open or pumped central heating systems with safety devices in accordance with PN-EN 12828:2013-05. MPM Wood

Plus boilers can operate in a closed system provided that a diaphragm expansion vessel, safety valve, control and

measurement fittings and DBV valve are installed in accordance with PN-EN 12828:2013-5, PN-EN 303-5:2021-09 and

recommendations contained in the boiler manual. Boilers installed in accordance with the recommendations of this

manual are not subject to the UDT. Boilers of the MPM Wood Plus type are recommended by the manufacturer mainly

for heating flats, detached houses, commercial pavilions, services, catering establishments, workshops, etc., where the

supply water temperature does not exceed 90°C and the operating pressure is 1.5 bar. The required flue gas draught

after the boiler is approx. 0.20 mbar. MPM Wood Plus boilers can be used to prepare domestic hot water with the use of

a heat exchanger installed in accordance with the PN-EN 12828:2013-05 standard. The selection of a boiler for heating a

given building should be strictly dependent on the heat balance drawn up for the heated premises in accordance with the

PN-EN 12831:2006 standard.

NOTE!

Due to the operating specifications of the solid fuel central heating boiler, supervision of the unit's

operation in the form of daily monitoring of the operating parameters is required. In the event of a power

failure, continuous monitoring of the boiler operation is required!

3. Boiler construction

The MPM Wood Plus boiler is an appliance of modern design, adapted for burning solid fuels (logs of deciduous trees -

beech or birch), gasifying the fuel. The gasification boiler has a structure which has separate chambers, in one of which

the process of fuel degassing takes place (production of combustible gas), while in the other - ceramic chamber, the

combustion of gases takes place. The fuel gasification boiler should be operated in conjunction with a buffer tank. The

minimum volume of the buffer tank is given in the Product Data Sheet in accordance with Commission Regulation (EU)

No 2015/1189 . The MPM Wood Plus boiler is made of approved P265GH grade steel boiler plates with welded

construction. It has a large loading chamber to prevent fuel from hanging up, a movable cast-iron grate, a metal-ceramic

burner, an exchanger with a vertical arrangement of flue channels in which a swirler is installed. It is also equipped with a

draught switch for easier firing and faster passage through the so-called dew point. Air is supplied to the combustion

chamber and ceramic nozzle, with both primary and secondary air adjustable. The burner consists of a metal baffle with a

secondary air supply No. 1 and a ceramic-lined swirl-box, which is an integral part of the burner. Secondary air No. 2 with

circular inlets is supplied to the swirl unit.

The MPM Wood Plus boiler is equipped with a convenient, large loading door and also has a firing and ash door in the

front part. An innovation is the introduction of a system of smoke removal from the loading chamber, the smoke

removal duct of the gasifying boiler and the method of forcing the draught of the gasified flue gases, which prevents

the escape of smoke into the boiler room when adding fuel. In the upper part of the boiler, under the casing flap, there is

a clean-out hatch giving access to all heat exchanger channels and the ceramic nozzle. There is a flame viewer in the top

outlet. In both side walls of the boiler there is a cleaning device for removal of impurities generated during the

combustion process. The boiler in the standard version is designed to operate using natural draught, regulated by a

mechanical draught measurer. In the upper part of the boiler there is a muffle for the draught measurer, a safety valve

and a thermometer. In the rear wall there is a supply and return water muffle, a DBV thermostatic valve muffle and a

drain valve muffle. The hot flue gases give up their heat by passing through a steel heat exchanger, which is a system of

vertical convection channels, where they are cooled. The cooled flue gases leave the boiler through a steel flue

connected to the flue pipe at the rear of the boiler. The heat exchanger is fully insulated with 40 mm thick mineral wool.

4. Fuel

The fuel for the MPM Wood Plus boilers is firewood (hardwood logs) with a circumference of approximately 20 - 30 cm.

The wood recommended by the manufacturer is beech or birch. The wood must be dry and seasoned for at least two years.

Burning wet wood reduces the efficiency and adversely affects the service life of the boiler. It is forbidden to burn cardboard

packaging in the boiler, whose unburned pieces can block the airflow through the cast iron grate, as well as plastic packaging

which can damage the ceramic burner and other boiler components, but above all is a health hazard. Fuel for the boiler

should meet the quality requirements contained in Table 7 of the PN-EN 303-5:2021-09 standard. The fuel parameters are

given in the tables below.

* Fuel parameters are given in relation to the operating state.

VERY IMPORTANT NOTICE!

It is forbidden to burn plastic materials and flammable materials (e.g. petrol, paraffin, solvent).The above

actions may contribute to boiler (furnace) damage, explosion, fire or damage to the health of the boiler

user.

NOTE!

Continuous use of wet fuels while maintaining a low flue gas temperature leads to accelerated wear of the

boiler, corrosion of the convection ducts, furnace plates, smoke stack and fouling of these surfaces. This is

caused by condensation of the products of combustion: water, nitrogen oxides and sulphur oxides which

create a very aggressive environment favouring accelerated corrosion.

7. Transport

The boilers are delivered in an assembled condition on a pallet in foil packaging. It is recommended that the boiler be

transported as close as possible to the final installation site in this packaging condition to minimise the possibility of

damage to the boiler casing. All packaging residues must be removed so that they do not pose a risk to people and

animals. The accessories and equipment are located inside the boiler, in the loading chamber. On the other hand, the

manuals and warranty cards are located under the top cleanout cover, packed and protected from damage. The

components are assembled by the installer according to the enclosed instructions. Use suitable lifting gear to lift and

lower the boiler. Before transporting the boiler, it should be secured against shifting and tilting on the vehicle platform

using straps, wedges or wooden blocks.

NOTE!

Transport the boiler in an upright position!

8. Boiler installation and requirements

The installation of the boiler should be carried out by qualified personnel with authorisations (specialised person with

appropriate training and authorisation to carry out maintenance and repair work). It is the installer's responsibility to

familiarise himself in detail with the product, its operation, the way the safety systems work and to impart the necessary

minimum knowledge on the commissioning and daily operation of the boiler to the end user. He should familiarise

himself with the instruction manual and the product before starting the installation work. The boiler operating at

nominal output should be connected to a heat buffer and then the buffer to the rest of the central heating system.

8.1. Open layout

The safeguarding of open-system waterborne heating installations must be carried out in accordance with the

requirements of the currently applicable, specific regulations of the country of destination (EN 12828+A1:2014-05

Heating installations in buildings - Design of waterborne central heating installations). The volume of the storage vessel

should be at least 4% of the volume of water contained in the entire heating system.

NOTA!

No valves may be installed on the rising and falling safety pipe and the circulation pipe, and these pipes and

the expansion vessel must be protected against water freezing in them.
