Biomaster Boiler 15-30 Instruction Manual
12
Recommended flue diameters for 30 kW boilers are:

square chimney: 18 cm x 18 cm

round
chimney: Φ18 cm
When settling the flue in the chimney special attention should be paid to the free
access to the boiler’s exhaust ventilator.
Remember that the flue gas discharged from the chimney is hot and the
lever will heat up.
Due to the high efficiency of the boiler, flue gases have a temperature
below 100
o
C, which may be the cause of moisture gathered in the
chimney. It is recommended to use stainless steel chimneys or stainless
steel chimney inserts.
2.5. Connecting the boiler to the installation
The
boiler
will function properly when the temperature inside the
boiler
chamber
is high enough, which means that feed water (leavin
g the boiler) should be at 70÷80
o
C, and return water should not be colder than 55
o
C. These parameters prevent the
boiler
from low temperature corrosion of material. To ensure proper boiler function
the manufacturer recommends installing a mixing valve and a heat accumulator.
The boiler has a G1½ thread connection. The boiler should be connected with the
installation using appropriate couplings.
If the boiler is equipped with a thermal safety valve sensor should be
mounted in a
G1½ coupler (17 Fig.1.4.2).
Install a safety valve.
Connect the water line using a G ½ valve (in the back of the
boiler
) with an elastic
hose, which should be disconnected after loading the water. During filling, all air
releases should be opened along the whole installation and gradually be closed until
the water flows from the overflow pipe in the expansion tank.
Lossless installations can be loaded with raw water, unless its hardness does not
exceed 10n. Otherwise the water should be treated. Mount the boiler equipment
(handles and grips).
Connection of the boiler to the power supply should comply with the PN-891E-
05012 norm (see chap. 2.7).
In case of any welding works when connecting the boiler to the central heating
installation, the power supply to the controller should be disconnected and the
controller itself should be covered. Temperature sensors should be removed
from their couplings and isolated from any surges and damage resulting from
welding. Disconnect the burner from the boiler.
