POWER SUPPLY LINE
The gas supply scheme is shown in
the diagram below. The gas train is
certified in accordance with regula-
tions EN 676 and is supplied sepa-
rately from the burner.
A manual shut off valve and anti-vi-
bration joint must be installed up-
stream of the gas valve, as shown
in the diagram.
In the case of a gas train with a
pressure regulator that is not incor-
porated in a monoblock valve,
we consider it useful to give the fol-
lowing practical advice regarding

the installation of accessory com-
ponents to the gas piping close to
the burner:
1) To prevent severe drops in pres-
sure on ignition it is advisble to
have a length of piping of 1.5 to
2 metres between the point of
application of the stabiliser or
pressure reducer and the bur-
ner. This pipe must have a dia-
meter equal to or greater than
the connector to the burner.
2) For the better working of the
pressure regulator it is advisa-
ble to apply it to the horizontal

piping, after the filter. The gas
pressure regulator must be
adjusted when working at maxi-
mum capacity and actually used
by the burner. The delivery pres-
sure must be adjusted to a le-
vel slightly below the maximum
obtainable. (that which is obtai-
ned when the regulation screw
is turned almost to the end); in
the specific case, when the re-
gulation screw is tightened, the
output pressure from the regu-
lator increases and when it is
loosened it decreases.
