Burner mounting
For mounting the burner to the boiler

been prepared according to the dimen-
sions given in the technical datasheets.
• Install the stud bolts in the connection
plate.
• Put the insulating backing and burner
in place and fasten by bolts.
Check before burner installation
1.
Select the nozzle according to
boiler output and combustion
chamber geometry.
2.
Set the mixing and ignition unit
according to the boiler output.
For the standard factory setting
refer to the burner head settings.
3.
Set the ignition electrodes on the
nozzle.
4.
Check the burner tube installation
depth according to the data speci-
fied by the burner and boiler
manufacturers.
Electrical connection
The electrical connection work compri-
sing all the installation materials, termi-
nals and earth connections must be
carried out in accordance with the appli-
cable regulations. For the electrical
installation of the burner care must be
taken to observe the circuit diagram
made out for the furnace system.
The electrical connection of the burner
and gas valves and instruments shall be
entrusted to authorized specialists only.
NOTE: For the installation of the con-
nection cables care must be taken to
provide cable loops of sufficient length
to allow for the swing-out of the boiler
door and burner.
Make sure after the completion of the
electrical connection work to check the
wiring of the electrical system of the
burner. This should include a check of
the direction of rotation of the burner
motor (fan).
Boiler inspection glass cooling
For cooling and cleaning the boiler
inspection glass a cooling line (e.g.
hose) may be installed from the burner
to the inspection glass. The burner is
provided with a connection socket for
this purpose.
