5. Press the Chimney Sweep button twice to select the minimum rate. The orange status light for the Chimney Sweep button flashes green briefly and minimum rate is
selected.
6. Check the CO is 8.9% ±0.1%. If the CO

Re-check both the maximum and minimum values if any adjustment has been made.
THERE MUST ALWAYS BE A DIFFERENCE OF 0.4% BETWEEN MAXIMUM & MINIMUM CO
7. Check the Combustion Performance (CO/CO
8. Briefly press the RESET button to return the boiler to normal operating status and remove the analyser probe.
Refit the sampling point plug & ensure there is no leakage of products !

11 Troubleshooting

11.1 Error Codes
Operation status and error codes are displayed on the 'chimney sweep' button (3) on the control panel. In normal operation this button is illuminated and goes off for a time once
periodically. When normal operation is interrupted for some reason this button will turn off and flash on a number of times periodically. The colour and number of flashes displayed
is dependent on the boiler status or fault condition.
The orange LEDs will flash at EVERY heating demand.
The number of flashes will correspond with the output of the boiler as shown in the table. e.g. 4 orange flashes = 21kW.
This is normal and does not indicate a fault condition.
"Error" or auto reset conditions (Green flashes on "chimney sweep")
The following table describes the conditions that may result in a blocking signal being displayed.
The boiler will try to re-start several times, and normal operation will resume once the blocking condition has been eliminated.
Should the conditions persist the boiler may go into lock-out (see following section)

Remedial actions by service engineer
Check system circulation & pump operation
Check demands for boiler operation (switched live operation)
Check temperature setting
Check temperature sensors in boiler
If condensate pump is wired to these terminals check
operation of condensate pump
Check wiring to BL terminals (link present or connections
to external device correct)
