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 (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.
- Check that the syphened drip is fully filled with water. If necessary, fill it via the special opening.
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.
