Maintenance

664Y5900 • A

 

It is recommended to stop the boiler and have it serviced during good weather 

conditions.

cleaninG the bUrner and the heatinG body

Set-up conditions

• 

Boiler shut-down

• 

External power supply isolated

• 

Oil supply closed

Procedure

 1.  Open the front panel.

 2.  Release the burner flange and place the burner in the maintenance position to clean it (see the 

burner manual).

 3.  Remove the burner

4.  Open the heating body door.

5.  Using a brush, clean the soot that may be present in the heating body and on the turbulators.

6.  Check the correct position of the braid.

Follow-on tasks

• 

Close the door and tighten with sufficient torque to ensure it is sealed against combustion 

products.

• 

Reinstall the burner flange and the burner.

• 

Close the front panel.

 

cleaninG the condenser

Set-up conditions

• 

Boiler shut-down

• 

External power supply isolated

• 

Oil supply closed

Procedure

 1.  Disconnect the flue pipe at the flue exhaust duct connection.

  2.  Inspect the inside and clean as required: 

• 

If the condenser is moderately dirty, pour a mixture of water and liquid soap (dish-washing 

type).

• 

If the condenser is very dirty, open the rear side panel, or the rear panel (

A

), to access the 

condenser. Open the condenser (

B

) and clean it using a synthetic bristle brush. 

 

Do not use the same brush as the one used to clean the heating body to prevent any 

risks of corrosion.
