Page 23: Settings
BENTONE Settings Setting the combustion assembly The burner is equipped with a lever that changes the position of the brake plate in the combustion head. This is used to set the correct pressure drop across the combustion assembly and thereby obtain good combustion without ripples. -
Page 24: Setting The Air Pressure Switch
BENTONE Setting the air pressure switch The air pressure switch must block the burner if the amount of air for combustion becomes too low. The air pressure switch must be set so that in the event of a lack of air supply at the burner’s max. or min. capacity reacts before the monitored pressure drops so much that poor combustion occurs. -
Page 25: Setting The Gas Pressure Switch, Min
BENTONE Setting the gas pressure switch, min. The gas pressure switch must react to too low a connection pressure to the burner, prevent the burner from starting and stop the burner during operation. The burner may start again when the connection pressure has risen above the set pressure on the gas pressure switch. -

Page 36: Control Of Flame Monitoring And Ionization Current
BENTONE Control of flame monitoring and ionization current The burner is monitored in the standard version according to the ionization principle. The ionization current must be checked at each service occasion. The ionization current is measured with a microampermeter (µA) which is connected in series with the flame electrode and the gas burner control. - Page 37 BENTONE 8.8.2 UV –detector (QRC) The UV sensor should not be exposed to temperatures higher than 60 °C. The current passing through the UV sensor when it is lighted must be at least 70 µA. The current can be measured using a rotary coil instrument. A check is necessary only if a malfunction is suspected.

Page 39: Handing Over Of The Installation
BENTONE Handing over of the installation • Make repeated start attempts to ensure that the adjustments function. • Close the ball valve during operation to check that the gas switch switches off at the set value. • Remove the hose for the air pressure switch to check that the burner locks out. -
Page 40: 10. Troubleshooting
BENTONE 10. Troubleshooting Conditions favourable to trouble-free operation of the system can only be guaranteed through the interaction between three factors: electricity, gas flow and combustion air. If any of these factors change, it may cause a malfunction. Before requesting servicing, check the following points: Are the system’s gas taps open? - Page 41 BENTONE Cause of fault Action Burner trips during pre-aeration: Air sensor faulty or incorrectly set. Increase/decrease air setting. Reduce air volume. Ignition load incorrectly set. Increase/decrease gas supply Reduce airflow. Gas pressure too low. Increase pressure. If necessary, contact gas supplier.
