GAS 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).
• Gas solenoids 8)-9)(B) must be as close as
possible to the burner to ensure gas reaches
the combustion head within the safety time
range of 3 s.
• Make sure that the pressure governor calibra-
tion range (colour of the spring) comprises the
pressure required by the burner.
