GAS LINE (A)
The gas train is to be connected on the right of
the burner, by flange 1) (A).
If it is necessary to connect it on the left of the
burner, loosen nuts and screws 3) and 4),
remove blind flange 2) together with its gasket
and fit them to flange 1) tightening the nuts and
screws.
Note
Once assembled the gas train, check for leaks.
GAS TRAIN (B)
It must be type-approved according to Stand-
ards and is supplied separately from the burner.
KEY TO LAYOUT (B)
1 - Gas input pipe for main burner
2 - Manual valve
3 - Low gas pressure switch
4 - Safety shut-off valve with SKP10
5 - NO vent valve
6 - Regulating shut off valve with SKP20
7 - Gas input pipe for pilot
8 - Gas adjustment butterfly valve
9 - Burner
10- High gas pressure switch
11- Manual valve (for seal control)
12- Pilot regulator
IMPORTANT
The pressure at the head of the burner from
table (C) - refers to zero in the combustion
chamber; to obtain true pressure, measured by
a U-type manometer, (see fig. (A) page 10) add
the counter-pressure of the boiler.
Note
See the accompanying instructions for the
adjustment of the gas train.
