Maintenance
CAUTION
Maintenance checks should be made more
frequently to appliances close to/or under
particularly hot areas.
• Repairs or maintenance must be performed
by a competent and qualified engineer.
• Disconnect the unit from the main power
and fuel supply before any maintenance
and/or inspection work.
• In order for the heater to properly work
and be maintained, we suggest regularly
cleaning and maintenance checks listed in
the following bullet points.
• Cleaning and maintenance intervals must
be carried out in relation to the appliance
use conditions, to the installation site and
to the environment.
• Any action to this effect must be carried out
safely by a qualified engineer.
• It is recommended that you use personal
protective equipment.
• All maintenance/cleaning operations
requiring the use of ladder or other means,
must be secured safely before use.
• It is advisable to report the changes on/or
to the appliance (date, description, type of
intervention, cause, etc.).
• If you are not going to use the appliance for
long periods of time, turn the main switch
"off". If long periods of unusual operation
occur, it is advisable to contact the
manufacturer on how to restart operation.
• Regularly check that all the screws used to
assemble the heater are properly fixed.
4.1 Cleaning of gas or oil burner
The burner should be cleaned by authorized
personnel, only.
Electro-ventilator cleaning
WARNING
The belts must have enough tension to
prevent sliding on the pulley. Too much
tension on the belts may cause the bear-
ings and/or shaft to break.
After removing the necessary panels, clean
the component using a wet cloth. Be sure to
periodically check the tension of the trans-
mission belts and the alignment between the
motor pulley and the fan pulley. The belts
should not be stretched; if the belt is pressed
on both sides with the hands, it should bend
between 20-30 mm. To manage the tension,
operate the two belt-stretching bolts.
Thermostat safety check
Check functionality of the safety thermostat
at least quarterly. Simulate its intervention
and it should be verified that the burner
goes out.
Checking electrical connections
Periodically check the correct tightening of
all electrical connections.
Security control
Periodically check the operation of all the
safety devices of the unit, by simulating
their intervention and making sure that the
unit stops safely.
Jacket cleaning
With a wet cloth, clean all the inner and outer
surfaces of the jacket. Do not use solvents
and / or abrasives products on the unit.
Flue gas analysis
Combustion control-analysis checks must
be done periodically.
Heat exchanger integrity
Periodically check for cracks and/or leak-
ages of the heat exchanger.
The heat exchanger should be cleaned, internally and
externally, by authorized personnel and in compliance
with specific rules. In general, we suggest cleaning
the exchanger at least once a year, at the beginning of
every winter.
For such operation, perform the following operations:
•
Disconnect the flue
•
Remove the burner (1)
•
Remove the panel (2)
•
Remove the inspection door (3)
•
Remove inspection door with flue connection (4)
•
Remove the panel (5)
•
Remove the inspection door (6)
•
Remove turbulators if present
•
With a brush, clean the inside of the fume pipes (7)
•
With a vacuum remove any soot that has been deposited in the
front (8) and rear (9) manifolds
•
If necessary, use a vacuum, remove any soot that has been
deposited inside the combustion chamber
•
If necessary, also remove the side panels and carry out external
cleaning of the heat exchanger
•
Reassemble all the pieces, especially considering the tightness and
replacing the gaskets, if needed
•
If necessary, also clean the flue pipe
CAUTION
Cleaning of the FSE 40 appliance must be carried out
similarly, considering that the tube bundle(7)
consists of only one row.
