I have a Weil Mclain AB-466E boiler, not sure on the age. What is the correct fuel nozzle size? We seem to go through a ton of fuel in the winter. I was looking up the size and its a pretty big boiler 144kbtu our house is about 1500 square feet so i would imagine that it may be related to that.

It currently has a 60 H 1.10 nozzle.
