Part Work to be carried out
Heater Check that the device is functioning correctly for all
safeties. Make sure all the screws are tightened.
Flue gas system Check the combustion air and flue gas pipe trace.
Check the seals and check for corrosion.
Condensate drain Check the siphon for contamination and clean it.
Burner Disconnect the electrodes, the electrical
connections of the combustion air fan and the gas
pipe at the gas valve. Remove the burner / fan / gas
mixer composition. Clean the burner with a brush,
vacuum cleaner or an air syringe. Check the burner
for damages and cracks in the surface. In case of
damages, replace it. Note: when re-inserting the gas
pipe, check the gasket for damage.
Ignite / Ionization
electrode Check the condition and clean if necessary. Check
the distance between the ignition electrodes
(4 +/- 0.5mm) and the distance between the
electrode and the burner (8 +/- 1mm). Check the
seal, replace if necessary. Check the height of the
ionization current. If this is lower than 3μA, check
the adjustment and the condition of the ionization
electrode and the connection to the ground.
