4.6.2. Burner assembly
The front door of models Melbury HE 3800-10000 is
provided with a norm-conform flange to fit the burner.
An additional intermediate flange may nevertheless be
necessary to fit the burner. Models Melbury HE
3800-10000 will in
most cases require a special flange. This intermediate
flange and related screws must be ordered separately
or supplied by the burner manufacturer.
CAUTION:
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).
4.6.3. 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.
CAUTION:
Customer installations (oil tubes, etc.) must not be attached to the boiler cladding!
Gas burner
Observe the separate instructions of the supplied
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.
INFORMATION:
Oil burner
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
additional panel on boiler!
Observe the separate instructions of the supplied
burner.
4.6.4. Part load operation
Stick to the minimum power of the supply heat according
the technical data, chapter 2.7 and 2.8.
