16 BOILER MAINTENANCE
In order to maintain the boiler under correct operating conditions, a checking operation is to be
made by DOMUSA’s authorised personnel on a yearly basis.
16.1 Boiler cleaning
To maintain the boiler under correct operating conditions, it is recommended to carry out one
annual clean-up of the combustion chamber, flue gases pipes and condensator. For it, with
the boiler, it is supplied an appropriate brush of clean-up. This brush is located in the front
side of the boiler, near door.
The combustion chamber and flue gases pipes should not be cleaned with chemical
products or steel hard brushes. It should put on special care after all the operations of
clean-up, making several power on cycles, checking the correct operation of all the
components.
For a correct clean-up, follow the following recommendations carefully:
Boiler corp cleaning

flue gasees tap, the burner and the external door of the boiler.
Condensator cleaning
- Open and retract the external top cover of the boiler, to access to the condensator,
located in the back side of the cast iron body.
