Step 6
- Once the air has been bled from the fuel pump
the burner should have established a flame on “Pump
Pressure (bar ) Setting 7 Bar*
*Please note the start pressure setting may differ as it can
be altered in the parameter screens under “Initial Pump
Pressure (bar)”.
If the burner has not successfully established a flame on the
Initial Pump Pressure setting then alter the “Fan Speed %” by
pressing or - buttons and retry.

Then press the + or - buttons to increase/decrease the
pump pressure setting (min 5bar to max 20bar depending
on boiler model). Then set/trim the fan speed so that flue
gas analyser reads the correct CO2% value given as 12.5-
13.5%.

Repeat the process for each “Pump Pressure (bar)”
setting
Step 7
- Now the boiler is firing, locate the combustion
analyser test points and carry out a smoke and
combustion test with the aid of a smoke pump and
combustion flue gas analyser to ensure the combustion
levels are suitable.
