• Remove the through nipple and secure it to the diesel filter by
inserting the shorter threaded part into the filter, taking care to
place aluminum seal N between them.
• On the top left side of the burner box, secure the diesel filter unit
and secure it to the metal panel by tightening with the ¼” nut.
• On the bottom left side of the burner box, secure second through
nipple and secure it to the metal panel by tightening with the ¼”
nut.
Warning
The threaded portion with internal conical chamfer M
must protrude in order to allow seal tightening with the
hose.
• Screw the flexible suction hose of the pump onto fitting M on the
diesel filter unit.
• Screw the flexible supply pipe of the pump onto the second
through nipple.
• Close the burner cover;
• Apply one of the two stickers with the serial number on the
nameplate of the machine characteristic data:
• Apply the second sticker with the serial number on the Assembly
and Installation Declaration contained in the user manual:
4.5. CONNECTION TO FUEL SUPPLY
Warning
The heater must be installed, set up, and used in
compliance with all applicable regulations.
Connection to the diesel supply pipe can be made by connecting the
fuel tank to the burner pump:
• directly, i.e., by using the burner’s diesel pump, in conformity to
the dimensions and lengths specified in the burner instruction
manual attached hereto.
• indirectly, i.e., by using an auxiliary return diesel pump. In this
case, contact a Customer Service Centre to ensure correct sizing
of the fuel system.
4.6. CONNECTION TO EXHAUST DUCT
Exhaust ducts must be in steel and conform to EN 1443.
Efficient combustion and trouble-free working of the burner depend
on efficient flue draft.
The unit must be connected to the chimney flue in compliance with
current legal regulations and in line with the following guidelines:
• The path of the flue pipe smoke should be as short as possible
and should slant upwards (minimum height 1 m);
• There should be no sharp curves in the pipes, and the diameter of
the pipes must never be reduced;
• there must always be a wind deflector to prevent the entrance of
rain and to prevent smoke from being blocked by the wind;
• flue draft must at least equal the level in the Technical
Specifications.
• every heater must have its own chimney;
The following diagrams show possible flue positions:
A) Minimum 1 m
B) As short as possible
C) Minimum 1 m
D) Chimney draught H shape
4.7. FIRST START-UP AND COMBUSTION ADJUSTMENT
Warning
The first start-up should always be carried out by a
specialised technician checking the correctness of the
combustion parameters.
Warning
The burner settings are pre-set at the factory and may not
comply with those required, therefore, the settings need to
be checked and, where necessary, corrected.
