6.7.2. Burner assembly
The front door is provided with a norm-conform flange for fitting the burner. An additional, intermediate flange
may be necessary to fit the burner. The intermediate flange and relative screws must be supplied by the burner
manufacturer.
Attention: The intermediate space between the burner tube and door hole must be filled with the supplied
insulating material before the burner is commissioned (see separate assembly guide).
6.7.3. Connection to the fuel supply
The whole installation may only be carried out by a licensed installation company. The installation must be
performed in accordance with local regulations. Particular care is to be taken that measures are foreseen to
prevent any burner start when the boiler door is open. Good practice is to connect the fuel supply to the burner in
such a way that the supply line has to be disconnected in order to be able to open the boiler door. Another
possibility is to attach the burner cables with glands in such a way that the connectors on the burner have to be
pulled to open the door.
Customer installations (oil tubes, etc.) must not be attached to the boiler casing!
6.7.3.1. Gas burner
Observe the separate instructions of the burner.
The gas installation must be dimensioned in accordance with the gas flow rate and the available gas pressure.
A shut-off valve must be installed in the gas supply line to the burner.
Important: Before the gas burner is connected to the gas line, it must be ensured that the line has been blown
through and is free from particles and chips.
The gas line must be checked for leakage during commissioning and after each disconnection (leak
detector spray).
The installation may only be operated using gas of the intended quality – observe burner type plate!
6.7.3.2. Oil burner
Observe the separate instructions of the burner.
6.7.4. Part load operation
Stick to the minimum power of the supply heat according the technical data, chapter 4.
6.8. Flue gas system
The pertinent rules of technology and good practice as well as the country-specific regulations and valid
standards must be observed.
The Melbury HE boilers have been developed using the latest technologies. The perfect balance existing
between boiler and chimney ensures optimal fuel use and economical system operation as a result.
6.8.1. Section determination
Sections must be calculated for boilers without draught.
Fuel type, power output, combustion gas temperature and quantity, chimney construction and height are all
important elements in determining sizes.
