BURNER CONNECTION TO THE BOILER
ASSEMBLING THE HEAD UNIT
The combustion head is packaged separately from the body of
the burner.
Anchor the head unit to the boiler door as follows:
• Position the insulating seals -13 on the sleeve.
•
Anchor the flange of the head unit -14 to the boiler -19 with the
stud bolts, washers and nuts provided -7.
CAUTION / WARNING
Completely seal the space between the burner sleeve and
the hole in the refractory material inside the boiler door with
suitable material.
ASSEMBLY OF VENTILATION SYSTEM
• The burner has an ambidextrous hinge opening for easy access
to the combustion head with fitted burner.
The burner is set as standard with hinge installation on RH side.
• To enable the maximum opening and so facilitate maintenance
operations, it is recommended to install the hinge opposite to
the position where the gas train is installed.
For a correct installation of the ventilating body, follow the proce-
dure described below:
• After installing the head group on the boiler, assemble the two
hinges -12 -17 on the lung, using the screws -21 and the corre-
sponding washers, without fully tightening them.
• Position the ventilating body -2 at the two junctions.
• To move the ventilating body, use the appropriate chains or ro-
pes (32) and hook them to the eyebolts.
• Insert pin -10, then lock it using the nuts -23 and the correspon-
ding washers, taking care that the abutting surfaces of the two
hinges are perfectly in contact with the corresponding surfaces
of the scroll.Do not tighten the nuts -23 too deeply, as this may
make hinge rotation difficult.
•
Tighten the centring pin -20 on the fan flange, opposite to the
hinge side.
• Keeping the chains anchored to the eyebolts, turn the venti-
lating body and place the fan flange in contact with the lung
flange, checking that the pin -20 is inserted in the corresponding
hole.Close the burner using the screws -11 and the correspon-
ding washers.
• Once the ventilating body is connected to the head unit, start
the final tightening of the four screws fixing the hinges, then
release the lifting chains or ropes.
• Connect the tie rod -15 to the control lever of the gas adjust-
ment throttle valve -26.
IMPORTANT
Every time the burner has to be opened, it is necessary to
disconnect gas solenoid valves connectors first.
