3. Service and maintenance

All adjustment, conversion, startup and periodical checking operations described below must only be carried out by Quali-

fied Personnel (meeting the professional technical requirements prescribed by current regulations).

FERROLI declines any liability for damage and/or injury caused by unqualified and unauthorised people tampering with the

unit.

3.1 Adjustments

Secondary air adjustment

During the startup stage it is advisable to check the setting of the secondary air adjustment device.

Light the boiler and carry out first loading with the same type of fuel to be used by the end-user.

Wait for the boiler to stabilise.

Using a combustion analyser check the CO in the fumes. If the CO content is > 0.5% gradually open the regulator until

obtaining a CO value of < 0.5%.

N.B.: opening the secondary air regulator of the boiler too much can result in uneven combustion (tendency to

"puff"). In this case close the regulator by 1/2 - 1 notch.

3.2 Startup

Checks to be made at first lighting, and after all maintenance operations that involved disconnecting from the

systems or operations on safety devices or parts of the boiler.

Before lighting the boiler

• Open any on-off valves between the boiler and the systems.

• Check correct prefilling of the expansion tank

• Fill the water system and make sure that all air contained in the boiler and the system has been vented.

• Make sure there are no water leaks in the system, connections or boiler.

• Check correct connection of the electrical system and efficiency of the earthing system

• Make sure there are no flammable liquids or materials in the immediate vicinity of the boiler

Checks during operation

• Turn the unit on as described in sec. 1.3.

• Check the seal of the water systems.

• Check the efficiency of the flue and air-fume ducts while the boiler is working.

• Check that the water is circulating properly between the boiler and the systems.

• Check the seal of the wood loading and combustion chamber doors.

• Check combustion and correct setting of the secondary air control device.

3.3 Maintenance

Warnings

- Before carrying out any maintenance make sure to disconnect the power to the boiler and wait until it is at

room temperature.

- Never drain (even partially) the water from the system, unless absolutely necessary.

- Do not clean the boiler and/or its parts with easily flammable substances (e.g. petrol, alcohol, etc.).

- Do not leave containers with flammable substances in the room where the boiler is installed.

- Do not clean the heating system with boiler operating.

- Use tube brushes and vacuum aspirators for cleaning; if rags are used, make sure they are not left inside

the boiler.
