4.5 Checks before taken into operation
Perform the following checks before taking the heater into operation.
•
Wiring, Ensure the heater is free of electricity by removing the plug from the socket outlet.
Now check that the connection is OK and that the wiring is connected properly.
•
Fuel leaks, Check that the oil system is leak-free and does not contain air.
•
Supply voltage; check if the supply voltage is sufficient.
•
Transport and combustion air flow, Check if the transport and combustion air exhaust is
free from any obstacles. In this way, you will prevent the heater from continuing to
operate while the air exhaust is blocked.
•
Burner pump pressure, The heater will not operate if the burner pressure is too high or too
low; refer to Measuring the burner pressure
•
Flame detection, Flame detection is by means of an LDS photocell. The LDS photocell
measures the brightness of the flame that arise when there occurs a flame. When the
measured brightness of the flame does not arise or is to low the heater will not function.
•
CO-value and CO2-readings in the combustion air too high a level of CO and/or CO2 in
an enclosed space can be harmful to people, animals and crops. You should therefore
always verify that the CO value and the CO2 content in the flue gas comply with the
requirements; refer to Measuring combustion values
•
