Connecting The Gas Pipe; Upper View - baltur Minicomist 7 Manual

FITTING THE BURNER TO THE BOILER AND

CONNECTING THE GAS PIPE

The burner is fitted with a sliding attachment flange on the burner
head. When fitting the burner to the boiler, this flange must be
correctly positioned is that the burner head penetrates the boiler by
the amount specified by the manufacturers of the boiler.
When the burner is fitted correctly to the boiler, proceed whit the
connection of the gas feed pipe (see
BT 8780 and BT 1387).
The size of the gas feed pipe must be proportional to its length and
to the gas delivery rate in accordance with the UNI standard (see
diagram), and it must be perfectly airtight and properly tested before
running the initial tests on the burner.
It is essential to fit a connector to this pipe, near to the burner, for the
easy dismounting of the burner and/or the opening of the boiler door.
FOR BURNERS WITH DUNGS GAS VALVE mod. MB.....
The DUNGS mod. MB.... valve has a filter and gas pressure sta-
biliser, which means that only the cut-off cock and the vibration
damper joint should be fitted to the gas feed pipe. A pressure
reduction unit should be installed outside the heating system only
in cases where the gas pressure exceeds the level permitted by
the standard (400 mm.C.A.).
It is recommended to put a bend directly on the burner gas train
before fitting the detachable connector. This is to allow the opening
of the boiler door, when the connector itself has been opened.
These details are clearly illustrated in the following diagram.
HYDRAULIC CONNECTIONS (LIGHT OIL)
The connection pipes between tank and burner must be comple-
tely tight. We suggest to use copper or steel pipes of an adequate
diameter (see list and drawing).
At the rigid pipes ands it must be fitted the fuel's detection gates.
Filters, flexible pipes and relative connection couplings are supplied
along with burner. Pump is equipped with suitable connecting points
(see drawing) for detection instruments (pressure gauge and vacu-
ummeter). Pressure drop in suction must not exceed 4,6 mm.W.G.
= to 35 cm.Hg. for a proper and silent operation. Probable max.
pressure on suction and on the return 1,5 bar.
