B diffuser vs 9 slot Carlin EZ Gas Burner
140,000 BTU New Yorker Steam boiler with a Carlin EZ gas burner conversion kit installed in 06. Was doing some reading and according to the literature the 9 slot diffuser would be better for short flame pattern for shorter combustion chamber units. Not certain what would dictate the use of B vs the 9 slot diffuser other than the original oil burner that was in the boiler to start with? And what effect on the boiler & or gas usage between the two diffusers if any would be? I understand that the orifice also plays a part in this as well and would it be worthwhile to have all of this torn down to verify that it is what it should be?
