I have a Weil Mclain sgo4 steam boiler with a data plate input of 144,000 btus. It has been converted to gas with a Wayne p265f bb conversion gun. The original Becket oil gun had a nozzle that burned 1.25 gph. The Wayne manual ( attached below) on page 5 gives instruction on how to size the gas orifice. We drilled it to the 144000 btu input from the data plate on the boiler. I have an hour meter and now that it has gotten cold the boiler runs a lot longer than in past years for the same outdoor temps. it seems like it is under-fired. After re reading the manual I think we need to redrill the orifice based on the original oil nozzle size. Page 5 in the manual shows for a 1.25gph ( original nozzle size) x 144000 for an input of 175000 btu. The manual says to size the orifice based on the gph of the oil nozzle. Does anyone agree with my understanding of the manual. It is currently drilled with a #2 bit and want to redrill with a letter c bit. we have clocked the meter and the boiler is burning just about 145000btus.
