6.2.1 Setting multiblock, MBC-65-DLE-S20
• Connect a pressure gauge to the test nipples
(1) Inlet pressure
(4) Regulator pressure
(5) Nozzle pressure
• Ensure the presence of air-free gas at the ball valve.
• Start the burner.
6.2.1.1 Setting gas flow
• The gas flow can be changed with the help of a 2 mm Allen key
on the adjustment screw (6).
• Greater gas flow, turn counter-clockwise (+).
• Lesser gas flow, turn clockwise (-).
NOTE!
When the gas flow is changed, a new check of the combustion must be
performed. Use a flue-gas instrument for this check.
6.2.1.2 Setting pressure regulator
A higher outlet pressure from the regulator can be required if, for instance,
the quantity setting is max. open and the factory setting is not sufficient.
• The regulator pressure can be changed with a 2 mm Allen key on the
adjustment screw (9).
• Adjustment clockwise gives higher pressure.
• Adjustment counter-clockwise gives lower pressure.
6.2.1.3 Replacement of coil
• Loosen screw (10).
• Remove the cover.
• Remove the circuit board.
• Disconnect the solenoid valve from the valve with a hexagonal screw.
• Install and fasten the new coil.
• Install and fasten the circuit board and cover.
6.2.1.4 Replacement of gas pressure switch (GW...A5)
• Loosen the two screws (11).
• Carefully remove the gas pressure switch.
• Install a new gas pressure switch.
• Attach the gas pressure switch with the two screws (11).
6.2.1.5 Important
When replacing gas pressure switches, inspecting filters via the gas
connection, etc., ensure that the O-rings and gaskets are positioned
correctly and that leak testing is performed after each operation. Also check
the function of the gas pressure switch and set it.
!
After completion of the jobs on the gas components, perform leakage control and
function control.
