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 the earth wire is connected to a
weel done earthing system.
– Open the gas tap and check the soundness of the connections, including 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 and dirt seperators are installed on the return water connection.
– Make sure that the system is charged with water and is thoroughly vented.
– Check that the circulation 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.
