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 appli-
cation of PED Directive 97/23/CEE as they meet the requirements of article 1 paragraph 3.6 of the Directive.
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 cock 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/or 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.
