of diameter 150mm. The impeller is to be exchanged
by plumber (never by customer) instead the existing impeller in case of installing the boiler
in chimney with a very high draught which is not able to reduce by any possible way. The
impeller is installed so that it was easier to adjust optimally the burner.
