15. Re-establish power supply to boiler and isolate controls.
16. Use manual override to start the boiler (press and hold for 5 seconds [-]-key
(green LED should appear in h-symbol)
17. The boiler should start with the run sequence (3) indicated in the 'code'-display,
see Par. 6.3.
18. Check the boiler for correct gas/air setup in full load by measuring the O
the flue gas (direct measurement of CO
levels of CO

Correct gas/air setup:
18 a. Force the boiler into high fire by pressing 'm' and [+] -keys simultaneously. The
code box will show and H in the display
18 b. When full load speed is reached check values against Table 16 (checking data)
- * With deviations greater than the permitted tolerance, a check must be made
to see if:
- the inlet pressure is sufficient,
- the correct restriction is fitted in the boiler.
18 c. Check flame via inspection window, the flame should be stable, mainly blue with
burner surface covered with orange dots.
18 d. Force the boiler into low fire by pressing the m' and [-] -keys simultaneously. The
code box will show an L in the display.
When part load speed is reached, check values against Table 16 (checking data) and
adjust if necessary using the screw on gas combi block (adjustment screw is protected
by a cover - both cover and adjustment screw are torx star type keys) turning screw
clockwise will increase CO
