Question

miller oil furnace dripping oil


I have a 3 to 4 year old Miller furnace. I had it check because it was dripping oil. I was told that I might have to replace the front panels that the gun screws to because it warped and the tube is sloping out and when the nozzle drips it is running out instead into the chamber is this noted to happen? thanks John

if you have nozzle drip the checkvalve in the oil pump is shot. it isn't normal to have oil dripping in the combustion chamber. You should add a solenoid valve to the nozzle line.

the blast tube should indeed pitch down towards the unit- afterdrip can also be caused by some air in the fuel line, but it's most likely is what Bigmike said-

if replacing the nozzle and bleeding the line doesn't help replace the pump or go with the selenoid valve-

Hi bigmike thanks for the info. Should I replace the pump and put in a solenoid valve or should I just by a new pump? I have another pump that got destroyed by grit can I take the check valve and replace the one in this pump? Do you have any idea what made the check valve go? Thanks John my email is johnny2941@yahoo.com

I would put in the solenoid valve first, then see how it works out. The valve will stop nozzle drip. The checks in the pumps go fairly often.
