Adjusting gas burner and boiler
The burner can be put into operation once the installation and assembly work has been completed.
•
Measure inlet pressure with U-pipe pressure gauge at measuring point "A".
max. 360 mbar (KE 15), max. 70 mbar (KE 10, static pressure)
min. 18 mbar (flow pressure) on RG1...-N
min. 35 mbar (flow pressure) on RG1-F
•
Burner and gas assembly are preset at factory to low output. This enables a soft burner start-up.
•
Adjusting the burner to the desired nominal output in accordance with the adjustment tables on
Pages 10, 11.
To do so:
•
Check gas working pressure with U-pipe pressure gauge at measuring point "B" outlet pressure.
Caution !
Minimum pressure difference (inlet-outlet pressure) 5 mbar!
•
Adjust gas pressure and air flow measurement "A" according to adjustment tables, PP. 10, 11.
•
Check exhaust gas values here without fail (CO, CO
2
or O
2
).
•
Depending on the system, the setting values must be corrected.
•
After completion of adjustment, check the setting data.
•
Check the gas pressure monitor after start-up. To do so, close ball valve slowly; burner must shut
down but not go into fault mode.
