17.1 - General warnings
This section must be brought to the installer’s attention,
highlighting the tasks to maintain proper system operation;
The installer is also obligated to inform the user that failure
to take care of and service this appliance could cause
malfunctions.
It is advisable to follow scheduled annual system
maintenance for the following reasons:
- to keep appliance output high, thereby saving fuel;
- to keep a high level of working safety;
- to keep the level of fuel environmental compatibility high;
ATTENTION!!! The appliance must only be
serviced by a professionally qualified technician.
ATTENTION!!! Before any maintenance
operations, disconnect the appliance from the electrical
mains using the specific switch located nearby.
ATTENTION!!! Close the gas cock before any
maintenance operations
The box below shows the operations to do at every
maintenance session.
17 - MAINTENANCE
17.1.1 - Gas leak check
1.- Make sure there are no gas leaks in the system;
2.- Check for gas leaks using a leak detector (with bubbles
or the like) or an equivalent system, thoroughly checking
the entire gas route from the counter to the appliance.
ATTENTION!!! Do not carry out these checks in
the presence of naked flames.
17.1.2 - Making sure the air intake and flue
exhaust ducts are in good conditions
1. - Check whether the air intake and flue exhaust ducts
have obstructions, signs of corrosion, physical damage,
water spots or signs of rust.
2. - Make sure the externally assembled intake grids and
flue exhaust outlets have no residue and are clean.
17.1.3 - Checking the system water
pressure
1.- Make sure the system is full of water and under
pressure as shown in section 18 technical features.
2.- Make sure there are no leaks in the hydraulic
connections.
ATTENTION!!! Repair any system or appliance
leaks. Continuously adding new water leads to
increased minerals that reduce the flow cross-section,
decreasing heat exchange and causing the heat
exchanger to overheat. All of this leads to failures and
reduced appliance life.
17.1.4 - Checking the ignition and
detection electrodes
1.- Remove the burner fan unit (as shown in section 17.3).
2.- Clean any operating material build-up from the
electrodes.
3.- Make sure the electrodes are in the correct position as
shown in section 17.5.
