reached.
- The control and safety devices (thermostats, gas valve, etc.) must operate correctly.
The burner and the inside of the combustion chamber must be clean. Soft brushes or
compressed air are recommended for cleaning the module, to prevent damage.

The module condensation water drain outlet should not be altered in any way and it must be kept
free of obstructions. It is advisable to perform an annual cleaning procedure of the condensation
collection siphon.
If a neutralisation system is installed at the condensation drain outlet, it should undergo periodical
maintenance, in accordance with the manufacturer's instructions.

Never use chemical products to clean the module. A plastic brush is enough, if the cleaning is
carried out annually.
The cleaning of the module and hydraulic circuit will have lasting effects if water with a hardness of
over 25ºF is treated previously. For softer water no treatment is required. In any case, a descaling
pump should be used to carry out the descaling process.
