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 con-
nected 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
properly 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.
– Purge the system, bleeding off the air present in the gas pipe by operating the pressure relief valve on
the gas valve inlet.
– The installer must provide the user with instruction in operation of the boiler and safety devices and hand
over the instruction booklet to the user.
