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.
Verify proper operation after servicing. Always reset the service interval counter after
full maintenance interval (every 4 years or 4000 hours of operation).
Reset service interval counter
At 4000 hours of use, "SERVICE" will scroll across the display. "Good" will display
as well alternatively.
To reset the 4000 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
4000.
For warranty conditions refer to the warranty card supplied with the boiler.
