POWER SUPPLY LINE
The gas supply scheme is shown in the diagram below. The gas
train is certified in accordance with regulations EN 676 and is sup-
plied separately from the burner.
A manual shut off valve and anti-vibration joint must be installed
upstream 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 following practical advice regar-
ding the installation of accessory components to the gas piping
close to the burner:
GENERAL GAS BURNER SYSTEM
Legend
1) Manual shut off valve
2) Anti-vibration joint
3) Gas filter
4) Minimum gas pressure switch
5) Safety valve
6) Pressure regulator
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
burner. This pipe must have a diameter equal to or greater
than the connector to the burner.
2) For the better working of the pressure regulator it is advisable
to apply it to the horizontal piping, after the filter. The gas pres-
sure regulator must be adjusted when working at maximum
capacity and actually used by the burner. The delivery pres-
sure must be adjusted to a level slightly below the maximum
obtainable. (that which is obtained when the regulation screw
is turned almost to the end); in the specific case, when the
regulation screw is tightened, the output pressure from the
regulator increases and when it is loosened it decreases.
