INSTALLING ON BOYLER

The dimensions of the gas adduction pipeline should be in function with it's length and with gas delivery according
to UNI regulations; It must be perfectly hermetic and adequately tested before the burner is general inspection. It
is indispensable to install a suitable pipe union in the pipeline, in proximity to the burner, to allow for easy disas-
sembly of the burner and opening of the boiler door.
The burner is equipped with a mounting flange which
slips on the burner head. When applying the burner to
the boiler, it is necessary to correctly position the
flange so that the burner head enters the furnace to
the extent specified by the boiler manufacture.
When the burner has been correctly fastened to the
boiler, proceed with connecting in to the gas pipeline.
The DUNGS mod. MB... valve incorporates a filter and
a gas pressure stabilizer and, therefore, only a cut-off
cock and an anti-vibration joint have to be fitted onto
the gas adduction pipeline. Only if the gas pressure
were above the maximum value allowed by regulations
(400 mm. W.C.) would it be necessary to install a
pressure reducer on the gas pipeline outside the
heating plant. We advise installing a bend directly onto
the burner gas ramp before applying the removable
fitting. This layout makes it possible to open the boiler
door, if there is one, after the fitting itself has been
opened. The above is clearly illustrated in the following
drawing (see BT 8871/GB).

1) Lock the flange B on the tube of the
burner via the supplied screw A and nut
C (n° 2 x BTG 20).
2) Position the insulating seal E on the
tube, interposing the cord F between
flange and seal.
3) Finally, fix the burner to the boiler via
the 4 stud bolts and relative nuts
(supplied).
N.B. Make sure the tube penetrates
into the combustion chamber as per
the boiler manufacturer's
instructions.
