COMMISSIONING
Start up the boiler as follows:
1) Power the boiler control panel on the general switch.
2) Make sure that the pressurization system has efficiently set the system to the minimum pressure.
3) The boiler must be operated at reduced power (max 50%) until reaching the water operating temperature in order to avoid
thermal shocks and thermal expansions between the various parts of the body.During the start-up phase, it is recommended to
limit the flow rate of the water passing through the boiler in order to reduce the condensation phenomenon and the consequent
acid corrosion of the parts in contact with flue gases.The critical dew point temperature is approximately 57°C with methane gas
and approximately 47°C with liquid fuels.

ATTENTION
–
On the boilers equipped with manhole, during the first start-up, it is essential to progressively tighten the two nuts (1) of
the hatch while pressure increases. Otherwise, the installation area may become dangerous for the operators in charge,
due to water seeping through and deteriorating gasket (2) rapidly.
–
Check the intervention of all safety and adjustment accessories described in the relevant chapter.
