INSTALLER INSTRUCTIONS
IMPORTANT
When carrying out commissioning of the boiler, you are highly recommended to perform the following checks:
Make sure that there are no liquids or inflammable materials in the immediate vicinity of the boiler.
Make sure that the electrical connections have been made correctly and that the earth wire is connected to a
good earthing system.
Open the gas tap and check the soundness of the connections, including that of the burner.
Make sure that the boiler is set for operation for the type of gas supplied.
Check that the flue pipe for the outlet of the products of the combustion is unobstructed.
Make sure that any shutoff valves are open.
Make sure that the system is charged with water and is thoroughly vented.
Check that the circulating pump is not locked.
Purge the system, bleeding off the air present in the gas pipe by operating the pressure relief valve on the gas
valve inlet.

1.4 TECHNICAL FEATURES
* When the “BT130 - BT150” tank units is connected to the boiler with the kit provided and the optional D.H.W. expansion vessel.
** Flow calculated with a fixed temperature on the D.H.W. potentiometer of 60°C for a maximum period of 10 minutes.
*** The gas flow refers to the inferior calorific value in standard conditions of 15°C - 1013 mbar
