BURNER CONNECTION

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:
- check the internal and external seal of the fuel supply system;
- regulate the fuel flow according to the power required by the boiler;
- check that the boiler is fired by the correct type of fuel;
- check that the fuel supply pressure is within the values specified on the burner rating plate;
- 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;
In particular, when using gas:
- Check that the feeding line and the gas ramp comply with the regulations in force;
- check that all the gas connections are sealed;
- 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.
- 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

check that the air spaces between the burner drau-
ght tube and the manhole are suitably filled with
thermoinsulating material. The boiler is supplied with
a piece of ceramic rope.
Should this not suit the burner used, use a braid of
different diameter bur same material.
