Shut-Down - REMEHA Quinta 85 Technical Information

18.4. Check the flame via the inspection window.
The flame should be stable, mainly blue.
18.5. Run the boiler at part-load by pressing the 'm'- and [-]-keys simultaneously.
18.6. When part-load speed is reached, check values against the table and adjust if
necessary using the Þ screw on the combi valve (see Fig. 20).
18.7. Check the flame via the inspection window. The flame should be stable,
with a regular blue flame distribution and orange burner surface.
18.8. Check the ionisation level, measurement in Volts between terminal 4 and earth,
minimum 4 µA (1 V dc ≡ 1 µA dc, see Fig. 22).
NOTE: The full load adjustment changes the gas/air graph slope angle, whilst the part
load adjustment shifts the base point on a parallel axis, each adjustment therefore
alters the previous setting slightly. Repeat the process 18.1 to 18.7 and re-check the
values as many times as necessary until they are correct at both loads.
19. Remove the flue gas analyser. Seal the test point.
20. Fit the boiler front panel.
21. Allow boiler to run up to its set flow temperature and shut off.
22. When pumps have stopped, vent the system and check the water pressure.
23. The boiler is now ready for use.
24. Check system controls.
25. Set system controls to the required values
NOTE: The Remeha Quinta 85 is supplied with a number of factory default settings
which should be correct for most installations. If other setting values are required: see
Par. 6.5 and 6.6.
