REMARKS
When tightening the flange, it is important to do it evenly so that the inner faces are parallel between
them. Since the locking system is highly efficient, do not tighten the nuts too much.
During this operation (tightening of the flange locking nuts) keep the body of the burner lifted so that
the combustion head is kept in a horizontal position.

GAS FEED SYSTEM AT LOW PRESSURE ( max. 400 mm.C.A )
When the burner has been correctly fastened to the boiler, proceed with connecting it to the gas pipeline (see BT 8780).
The dimension of the gas adduction pipeline should be in proportion to its length and to gas delivery and the load loss
should not exceed 5 mm W. C. (see diagram). It must also be perfectly hermetic and adequately tested before the
burner’s general inspection. It is indispensable to install a proper fitting on the pipeline, in proximity to the burner, to allow
for easy disassembling of the burner and/or opening of the boiler door.
In addition, the following should be installed: a cut -off cock,
a gas filter, a stabilizer or a pressure regulator (when the
feed pressure is superior to 400 mm W. C. = 0,04 Kg/cm2),
and an antivibration joint. These parts should be installed as
described in our drawing (see BT 8780).
We consider it useful to give the following practical tips for
installing the essential accessories on the gas pipeline near
to the burner:
1) To avoid big drops in pressure on ignition, the length of
the pipeline between the point where the stabilizer or
reducer is fitted and the burner should be from 1,5 to 2 m.
This pipe must have a diameter equal or superior to that of
the burner attachment fitting.
2) The fitting must be applied on horizontal pipes.
This is to avoid any impurities falling into the pipes or
entering the stabilizer during cleaning.
3) To get the best performance out of the pressure stabilizer,
it is advisable to fit it onto horizontal pipes, after the filter.
In this way, the vertical movement of the entire mobile part
(shutter) of the stabilizer is rapid. (If the movement of the
mobile part were horizontal - with the stabilizer fitted into
vertical pipes - friction to the guide bush/es of the pin to
which the entire mobile part is fitted would delay movement).
4) 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 pipe fitting itself has been opened.
The above information is clearly illustrated in drawing BT
8780.

GAS FEED SYSTEM AT AVERAGE PRESSURE a few bars (see BT 8058-BT 8530/1-8531/1)
When high delivery is required, the Gas Distributing
Company requests the installation of a unit comprising
a pressure reducer and a meter, and then connects it
to the gas pipe network at average pressure (a few
bars).
This unit can be supplied by the Gas Distributing
Company or by the user, but should be according to
the Gas Company’s precise instructions.
The unit’s pressure reducer should be large enough to
supply the maximum gas delivery required by the
burner at the rate of pressure normally estimated for
it.
From experience, we would recommend utilising a
large-scale reducer in order to attenuate the notable
increase in pressure which occurs when the burner
comes to a standstill, with a high delivery. (Regulations
require that the gas valves close in less than one
second).
As an indication, we would advise using a reducer
capable of producing at delivery (m3/h) about double
that of the maximum amount estimated for the burner.
If several burners are to be used, each one should
have its own pressure reducer; this will enable the
gas feed pressure to the burner to be maintained at a
constant level even if only one burner is operating at
the time.
Consequently, it is possible to accurately regulate the
delivery and therefore the combustion, and thus
improve yield.
The dimension of the gas pipeline should be in function
with the quantity of gas it has to deliver. We advise
maintaining the load loss at a low level (not more than
10% of the gas pressure value at the burner); it should
be kept in mind that the load loss is added to the
pressure existing when the burner stops and therefore
a subsequent start up will occur at a pressure that
rises in accordance with an increase in the pipe’s load
loss.
Should the gas pressure reach unacceptable values when the burner stops (rapid closure of the gas valves), it is necessary
to install between the reducer and the first valve of the burner an automatic overflow valve and relative conveying pipe, of
suitable section, in the open air.
The end of conveying pipe in the open air should terminate in a suitable place, be protected from rain and have a flame
trap. The overflow valve should be regulated in such a way as to completely unload excessive pressure.
See diagram BT 8058 for gas pipeline dimensions.
Near to the burner should also be fitted a cut-off ball cock, a gas filter, an anti-vibration joint and a flanged fitting (see
BT 8530/1 and BT 8531/1).
