Inspection And Servicing Instructions - REMEHA Quinta 30 Technical Information

11 INSPECTION AND SERVICING INSTRUCTIONS

11.1 General
The Remeha Quinta 30 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 rele-
vant training and certification (ie CORGI - ACOPS - etc.).
11.2 Annual Inspection
The annual inspection of the Remeha Quinta 30 as follows:
- check combustion characteristics, see Table 16.
- clean the condensate siphon (refill with clean 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) If ionisation level < 4 µA dc, 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)
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
Note: If flue gas temperature is more than 30°C above the boiler return water tempe-
rature the heat exchanger must be cleaned see Par. 11.3.
