4 INSTALLATION
Before
connecting the boiler, perform the following operations:
•
Thoroughly clean all the system pipes in order to remove any foreign matter that could affect correct
operation of the boiler;
•
Check that the flue has an adequate draught , that there is no narrowing of passages and that it is free
from debris; also check that other appliances do not discharge into the flue (unless designed to serve
several utilities). See the regulations in force.
4.1 BURNER
Before installation you are advised to thoroughly clean the inside of all the fuel supply system pipes in order
to remove any foreign matter that could affect correct operation of the boiler. See technical specification
tables and check the max pressure value inside the furnace. The value found on the table may also increase
by 20% if heavy oil is used instead of gas or light oil; furthermore the following checks should also be carried
out:
a) Check the internal and external seal of the fuel supply system;
b) Regulate the fuel flow according to the power required by the boiler;
c) Check that the boiler is fired by the correct type of fuel;
d) Check that the fuel supply pressure is within the values specified on the burner rating plate;
e) Check that the fuel supply system is sized for the maximum flow rate necessary for the boiler and that it
is provided with all control and safety devices provided for by the regulations referred to above;
f) Check that the boiler room vents are sized in order to guarantee the air flow established by the
regulations referred to above and that they are in any case sufficient to obtain perfect combustion.
In particular, when using gas:
g) Check that the feeding line and the gas ramp comply with the regulations in force;
h) Check that all the gas connections are sealed;
i) Check that the gas pipes are not used as earth connections for electrical appliances.
If the boiler is not going to be used for some time, close the fuel supply cock or cocks.
IMPORTANT: verify that the spaces between the burner sleeve and the plug are suitable filled with flame-
resistant ceramic insulation (Fig. 1).
All details on the draught tube length ( P6 ), the diameter of the burner hole ( Øb ) and the pressurization are included
in the par. Technical Specifications.
