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 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.
FONDERIE SIME S.p.A. of Via Garbo 27 - Legnago (VR) - Italy declares that its hot water boilers, which bear the CE
mark under Gas Directive 90/396/CEE and are fitted with a safety thermostat calibrated to a maximum of 110°C,
are not subject to application of PED Directive 97/23/CEE as they meet the requirements of article 1 paragraph
3.6 of the Directive.
