Our Company declares that MURELLE HM ErP boilers comply with the essential requirements of the fol-
lowing directives:
- Boiler Efficiency Directive 92/42/EEC
- Gas Appliances Directive 2009/142/EC up to 20/04/18 and Gas Regulation 2016/426/EC from 21/04/18
- Electromagnetic Compatibility Directive 2014/30/UE
- Low Voltage Directive 2014/35/UE
- Ecodesign Directive 2009/125/EC
- Regulation (EU) N. 813/2013 - 811/2013
- Energy Labelling 2010/30/EC
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.
– 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.
