4.0 START-UP
4.1 PRELIMINARY OPERATIONS
Before starting the Boiler, the installer must carry out the following checks:
 Make sure that all the electrical connections have been carried out following the instructions
given in the Burner Manual.
 Make sure that the smoke outlet is thermally sealed.
 Make sure that the intake and delivery parts are free and not obstructed.
 Make sure that the burner is correctly fixed to the Boiler.
 Make sure that all 3 doors of the Boiler are closed correctly, so that the flame is only generated
inside the combustion chamber.
 Make sure that the auger and the flaxible hose for connection to the burner have been connected
and positioned correctly.
 Fill the container with Pellets only, and not with any other fuel.
 Check that the safety valve is connected and working correctly.
 Inform all users about the relative risks and dangers, and also train them about how the Boiler
works.
N.B.= the checks indicated above must also be carried out by the User or Maintenance
Technician following any type of maintenance operation that caused the systems to be
disconnected, or after intervening on the safety devices or on parts of the Boiler or Burner
4.2 FIRST START-UP AND SHUT-DOWN
When starting for the first time, some of the oil and grease that coat the combustion
chamber will tend to evaporate.
The room must be aired to allow these fumes to exit.
For the Start-Up, proceed as follows:
1) Make sure that the Boiler is connected to the Hydraulic system
2) Connect the Burner to the mains
3) Ignite the Burner; for ignition, see the BURNER MANUAL and follow the instructions.
The burner electronic board ignites the flame and keeps it constantly under control, The board al-
so monitors any problems that may appear on the burner display
To SOLVE possible PROBLEMS, consult the BURNER MANUAL.
To shut down the Boiler, it is sufficient: first, to turn off the burner, wait for the cooling cycle to be
completed, and once it is finished, disconnect the Burner from the mains.

3.4 INSTALLATION
The user is fully responsible for the work carried out or still to be carried out in
the installation area.
Before starting assembly operations, the installer must adhere to the safety
precautions required by law and, in particular:
 must ensure that the provisions for the system comply with local, national and European
laws
 Must check if specific authorisation is required because of urban, architectural and fire
prevention regulations ;
 Must scrupulously follow the instructions given in this manual, above all paragraphs (3.1) on
page 10 and (3.2 - 3.3) on page 11
Must always use the personal protective devices and all the protective means required in
compliance with current legislation in force.
3.5 ELECTRICAL CONNECTION
The BMax boiler does not need any electrical connection, but the burner does (SEE THE
BURNER MANUAL). These electrical connections must be carried out by a specialised,
qualified technician who is authorised to work, in line with current legislation in force.
3.6 CONNECTION TO THE HEATING PLANT
 Choice of the correct size of the boiler and the heating plant, as well as the choice of the type of
plant to be realised, are the responsibility of the installer and/or the designer.
 It is advisable to connect the machinery to the heating system by means of a three-piece joint, in
order to be able to remove it without causing damage in the event of malfunctioning, in particular, to
the return flow connection. In fact, it could be useful to install a T-junction with a stop cock to be able
to drain the plant for maintenance work.
 For correct functioning of the plant it is advisable to use a mixing valve set at 55 °C as a way to
regulate the temperature both of the plant and the boiler, and to be able to increase the temperature
of the return flow into the boiler, in order to protect the parts from dangerous temperature drops
caused by condensation in the flues.
 After having completed the connections to the hydraulic system, the heating plant and the boiler
must be filled. Before this operation, it is necessary to check the hardness of the water and of water
residue, and if needed, install (for example, if there is water with a fixed residue greater than 300 mg/
l at 180°C) a water softener before the entry point of the water supply pipe. This will ensure optimal
conservation of the inside surfaces of the boiler body, but also of the whole heating plant. Briefly, the
following operations are necessary for filling: open any sectioning valves on the plant; completely
open all the bleeder valves on all the radiators, so that all the air can escape without leaving air
bubbles; fill the system very slowly using the Drainage Connection (4) of the boiler (see Pg. 7)
keeping the bleeder valves of the radiators open even when a trickle of water starts to run, again to
ensure that no air bubbles are created. When the installation is completed, it is a good rule to keep
checking the seals of the hydraulic connections for at least 2 or 3 days for any leakage.

3.0 INSTALLATION
3.1 RESPONSIBILITY OF THE INSTALLER
The installer is responsible for : ,checking the chimney flue, the air vents and all the
necessary actions for installing the boiler. The installer is also responsible for: ensuring that all
the safety regulations required by the specific legislation in force in the state, region, province
and city of installation are respected.
The use is subordinated to the instructions contained in the present manual and all the
safety regulations required by the specific legislation in force in the state, region, province, city
where the boiler is installed must be complied to.
The UNI 10683 Directive defines the responsibilities of the installer: the installer must
verify:
 The type of plant to be installed
 The compatibility of the installation area with the machinery itself in that the minim um
distances required by the manufacturer must be respected
 The manufacturer’s requirements for the boiler regarding the smoke exhaust system
regulations (smoke channels and chimney flues)
 The internal section of the chimney, the material in which it is constructed, the
homogeneity of the section, the absence of obstructions
 The possibility of installing external air outlets and the sizes of existing ones
 The possibility of the co-existence of the boiler to be installed with pre-existing
equipment

If the checks are positive, the machine can then be installed, so long as the instructions
supplied by the manufacturer and the regulations concerning safety and fire prevention are
scrupulously observed.
When the installation is completed, there must be a test start-up of the plant, for a duration of not less than
30 minutes, to check the general operational state of the equipment.
When the installation is completed and after the first start-up of the plant, the installer
must consign the following documentation to the client:
 The machine use and maintenance manual (if not present inside the machinery)
 The necessary documentation in compliance with existing laws

3.2 SMOKE EXHAUST
The smoke duct and connection to the chimney must be made in compliance with
standards and laws in force. The pipes used must be rigid, resistant to temperature and
mechanical stress, and watertight
The chimney must guarantee the minimum depression indicated by current technical
standards, considering a “Zero” pressure at the connection point with the smoke duct.
Unsuitable or badly-sized chimneys or smoke ducts can increase combustion noise and
negatively influence the generator combustion parameters.
Non-insulated outlet ducts are a potential source of danger.
The joints must be sealed using material that is resistant to a minimum temperature of
350°C (e.g. fillers, rubber cement, silicon preparations).
N.B.= Refer to the TECHNICAL DATA TABLE (paragraph 2.4) on page 9 for the size of the
generator smoke duct .
3.3 POSITION
The POSITION in which the boiler is to be placed must be checked/established by the
system installer or by a qualified technician, and account must be taken of technical
requirements and laws in force.
To position the boiler correctly, make sure that :
 it is placed it on a surface that has been levelled and is able to support the weight;
 the MINIMUM distances indicated in the figures below are respected to allow
correct air flow and to allow normal CLEANING and MAINTENANCE operations to be
carried out;

