11 INSPECTION AND SERVICING INSTRUCTIONS

11.1 General

The Remeha Quinta has been designed to need minimum maintenance, but to ensure
optimum efficiency we advise that once a year the boiler should be checked and if
necessary cleaned and reset.
All service and maintenance must be carried out by a qualified Engineer with the
relevant training and certification (ie CORGI - ACOPS - etc.).

11.2 Annual Inspection

The annual inspection of the Remeha Quinta as follows:
- check combustion characteristics, ref. table 16.
- clean the condensate siphon (re-fill with clear water)
- check for leaks (water side, flue gas side and gas soundness)
- check flue and air inlet system is clear and gas/water tight
- check system pressure
- check control settings
- check ionisation level, minimum 4 μA dc (ionisation measurement in Volts between
terminal 4 and earthing, 1V dc  1 μA dc, see Fig. 23).
If ionisation level < 4 A dc or not present, check:
- CO at both part and full flame
2
- Is flame core visible?
- Is flame geometry stable?
- Ignition probe earthing
- Temperature sensors for loss current (humidty on sensors)
- Is analog control (0 - 10 V) volt free?
Visual check of ignition/ionisation probes:
- if white oxydes show, use sand paper or screwdriver for cleaning
- check geometry and distance between both probes, i.e. 3 to 4 mm.
- clean and re-set the ignition electrode
