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 and has been pro-
perly installed.
– 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 (CAUTION: Remember to release the pump coupled with the control
panel, if necessary, to protect the electronic control card).
– Purge the system, bleeding off the air present in the gas pipe by operating the pressure relief valve on the gas
valve inlet.
