Correct gas/air setup:

18.1. Connect the flue gas analyser, ensuring the connections are gas tight.
18.2. Run the boiler at full-load by pressing ‘

’- and [

]-keys simultaneously.

18.3. When full-load speed is reached, check values against the table and adjust if

necessary using the

screw on the venturi

(see Fig. 20).
