Pipe installations
Before installing the boiler, the heating network must be flushed and checked by means of a
water-pressure test. After installation, make sure that all joints are tight. e factory is not
responsible for damages caused by leaking joints.
Dirt trap and manometer installation
It is recommended that the dirt trap delivered with the boiler be installed in the cold water
pipe before the heat exchanger. ere is no manometer in the boiler. erefore, it must be
installed in the heating network.
Safety valve installation
e valve must be CE marked. Its maximum opening pressure must be 1.5 bar and its mini-
mum size DN 15. e safety valve must be chosen according to the highest pressure class of
the combination of devices. Devices that can close the connection must not be installed be-
tween the valve and the boiler. e blowdown pipe must be dimensioned and installed in such
a way that it does not limit the valve blowdown efficiency and does not cause dangerous situa-
tions during the operation of the valve
.
Electrical installations
A pellet burner, a 6/9 kW electrical resistance and an internal circulation pump with its
switches are installed in the boiler and are ready for use. e boiler contains an overheat pro-
tection for the burner and the electrical resistance. e electrical installations related to the
boiler must be carried out by an installer with the relevant qualifications. e connection is
carried out according to the enclosed connection diagram. A safety/maintenance switch must
be installed in the voltage supply system of the boiler.
Before commissioning
Before starting the boiler, the following should be checked:
• the heating network and the boiler are full of water (pressure at least 0.5 bar).
• air is removed from the internal circulation pump through the venting screw located in the
pump head.
• the flue damper (if any) is open.
• the circulation damper located in the convection part of the boiler is in place.
• the circulation pump is running.
• the network valves are open.
• the ventilation air intake is open.
• the safety valve is in working order and there are no obstacles between it and the boiler.

e boiler should be installed by a company with the proper professional qualifications. e
installation must be carried out in such a way that it meets the requirements of at least Stand-
ard SFS 3332.
NOTE!
All electrical connections must be carried out by a professionally-qualied electrician.
Space requirement
e boiler room must be rated at fire resistance class EI 30 or above according to Part E9 of
the National Building Code of Finland. At least one metre of free space must be left in front of
the boiler for cleaning and maintenance operations. It is also recommended to leave about 80
cm of free space on the other side and at least 50 cm above the boiler.
NOTE!
The boiler must located be at a distance of no less than 180 mm from the back wall. In addition, it
must be possible to remove the ue gas blower whenever maintenance requires it.
Flue pipe connection and combustion air intake
Silicon sealant with a temperature resistance of 350°C can be used as a sealing compound for
joints. e flue pipe must be made of steel or equivalent material. e flue pipe length must
be dimensioned according to the building requirements. e ventilation air intake must not be
covered.
