Instructions for the connection of the fuel tank
The dimensions of the fuel tank support structure should be ad-
equate for the dimensions of the tank and the weight of the
tank when full. If the fuel tank is located on the outside, this and
the coupling pipe should be thermally insulated.

The tank should be placed higher than the burner, with a differ-
ence of level H between the output of the fuel tank (9) and the
burner input (10) greater than 4 m. When the boiler is not being
used, empty the fuel tank to prevent corrosion.
