COMBUSTION
Once adjustment has been made, wait until CO
2
level
stabilises and recheck the combustion. Repeat the above
steps as necessary.
Check that CO
2
levels are within stated levels at minimum
rate, turn knob to first segment on the display.
Using the method detailed above, run the boiler at its
minimum output. Wait for the boiler to stabilise and
perform the combustion analysis, check the results.
If found to be inconsistent, turn the gas valve regulator
B (See Fig. 21) in the appropriate direction. Turning
clockwise will increase the CO
2
turning anti-clockwise will
decrease the CO
2
. Please note that due to the sensitivity
of the screw, only small adjustments will be necessary
(1/8 of a turn).
Once adjustment has been made, wait until the CO
2
level
stabilises and recheck combustion. Repeat the above
steps as necessary.
After completion of calibration, recheck the CO
2
, at
maximum output.

Turn the cooker burner to mark H and ensure programmer
is set to MANUAL , the burner should light within 60
seconds.
Check within 5 minutes that the gas consumption is ±5%
of the stated heat input. 14.6 kW.
Connect a suitable gas analyser to the sample point on
the hob or flue outlet. Ensure the CO/CO
2
content is:
CO
2
8.8 - 10.2%
CO 0 - 100ppm
If these levels cannot be obtained, check gas rate and
adjust the throttle screw if required and allow readings to
stabilise. (See Fig. 22).
