Visual inspection of the flame (2 and 4 year maintenance)
The burner must flame evenly over the entire surface when operating correctly. The
flame must burn with a clear, blue, stable flame.
Check the flame through the inspection glass in the ignition probe (fig. 44).
The flame pattern should be as shown in the figures below.

Further checks:
- Inspect the pressure relief valve
- Clean the water filter in the return pipe
- Check the pH of the water or glycol/water mixture.
The combustion must be checked and adjusted if required at both the 2
year/4000 hour and 4 year/8000 hour service intervals with a properly working
combustion analyzer.
Verify proper operation after servicing. Always reset the service interval counter after
full maintenance interval (every 4 years or 8000 hours of operation).
Reset service interval counter
At 8000 hours of use, "SERVICE" will scroll across the display. "Good" will display
as well alternatively.
To reset the 8000 hour service notification:
- Enter the 1st Tier Settings: 123 Code
- Briefly press "Mode" again until the Service Chapter is displayed (SERV)
- Hold the "Store" button until SERV flashes once—the service notification will no
longer show during normal operation and the countdown to service will reset to
8000.
For warranty conditions refer to the warranty supplied with the boiler.
