The burner can be put into operation once the gas and electrical installation and assembly work has been
completed.
•
Measure inlet pressure with U-pipe pressure gauge at measuring point "p

max. 100 mbar (static pressure) for KEV 220, KEV 225
max. 360 mbar (static pressure) for MB407, MB412, MBC300

min. 35 mbar (flow pressure) for -F
Burner and gas ramp are preset to low output at the factory. This ensures an initial safe start-up of the
burner.
•
Use the adjustment tables to set the burner to the desired nominal output.
For this:
•
Check the nozzle pressure with U-pipe pressure gauge at measuring point "p
G
".
•
Adjust gas pressure and air flow dimension "A" according to adjustment tables.
•
Be sure to check the exhaust gas values (CO, CO
2
and/or O
2
).
•
Depending on the system, the setting values must be corrected.
•
The setting data must be logged once adjustment is complete.
•
Check the gas pressure controller after start-up. Close the ball valve slowly, the burner must switch off
without triggering a fault.
The gas supply line and gas assembly must not subject the burner to tensile, compressive
or torsional forces; since these could adversely affect operational safety.
