4.1 COMBUSTION ADJUSTMENT

In conformity with Efficiency Directive 92/42/EEC the application of the burner on the boiler, adjustment and test-
ing must be carried out observing the instruction manual of the boiler, including verification of the CO and CO
concentration in the flue gases, their temperatures and the average temperature of the water in the boiler.
To suit the required appliance output, fit the proper nozzle, then adjust the pump pressure and the air damp-
er opening in accordance with the following table.
ADJUSTMENTS CARRIED OUT IN FACTORY FOR SIME BOILERS
The values shown in the table are measured on a SIME boiler (as per EN 267).
