The fine adjustment on the gas combination
control is made on the basis of the flue gas
measurements on the chimney.
▷
The following are required for setting:
– 2.5 mm Allen key,
– Pressure gauge with display range 0 to 50 mbar,
– Flue gas analyzer. The flue gas analyzer must be
able to measure λ (lambda), O

.
The sensor should be suitable for temperatures
of up to 300°C.
▷
The inlet pressure p

must comply with the
technical data, see page 26 (Technical data).
Important! Always check the inlet pressure when
the RGA 100 is in operation.
