GAS FEEDING LINE

• The gas train must be connected to the gas
attachment 1)(A), using 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.
• Make sure that the pressure governor calibra-
tion range (colour of the spring) comprises the
pressure required by the burner.
