attachment 1)(A), using the flange 2), gasket
3) and screws 4) supplied with the burner.
• The gas train can enter the burner from the
right or left side, depending on which is the
most convenient, see fig. (A).
• The gas solenoids must be as close as possi-
ble to the burner, to ensure that the gas
reaches the combustion head within the safety
time of 3s.
GAS TRAIN (B)
Approved, together with the burner, according to
the regulation EN 676, and supplied separately
from the burner, with the code indicated in the
tables (C). It is possible to use the one-stage

limiting the ignition output according to the
standard, with the aid of only the brake, as spec-
ified on page 12.
