Hi Folks
I just installed a new Riello RDB 1 replacing a older G5 BF, its in a grant 50-90 Balanced Flue (late 90s, utility model). I am near the end of the air adjustment to achieve figures which are within tolerance e.g 02% 4.7, CO ppm 12, CO2% 12, Flue gas temp 226, excess air 29% and Eff gross at 84%. There are no restrictions to air intake etc and I am of the opinion the RDB 1 is at the upper end of its capability hence near wide open air adjustment (6 on the scale to achieve the above figures) any thoughts?
Cheers
