Appropriate Use of the Boiler

This boiler MUST be used for the use for which it has been expressively designed. Any other
use shall be considered improper and therefore dangerous.
This boiler is designed to heat water at a temperature below the boiling point at atmospheric
pressure.

Prerequisite System Flushing

Before installing the boiler the following actions MUST be carried out by a competent engineer
or technician:
a) The whole system should be thoroughly flushed in order to remove any
residual dirt or grime which could compromise correct boiler operation.
b) Check that the boiler has been preset for operating with the gas type
available. This is verifiable via the indication on the packaging and on the
data badge;
c) Check that the flue pipe has an adequate draft, does not have any
constrictions or obstructions, and that no other appliance's flue outlets have
been fitted, unless the flue pipe is serving more than one heating appliance,
according to the specific standards and regulations in force. The connection
between the boiler and flue outlet can be made only after this verification has
been carried out.
