international heater co. model OLS-111F oil furnace

[BryanS]

This is my bro in law and sisters furnace. I know this thing is pretty old. I'm doing a tune up on this since they just bought this house. I don't really work on oil furnaces, but these are designed just like the new generation heaters I worked on in the military. The model says what I listed on the title. It has another number which is CS195-60 at the top of the data plate. From what I gathered this is a 60% efficient.

Does anyone have any idea who manufacturered this unit, or a part# for a set of electrodes that will work on this. The electrodes appear to be about 6 inches from the end of the threads to the tips. They have two long flat bars that hook on the back. It would be nice to replace those too since they are a bit pitted.

I would say they look like this set.

I ended up ordering these. All the measurements matched except the bus bars are a little longer.

I have an issue with this oil furnace. I'm trying to replace a White Rodgers 668-401 oil furnace primary control with a Honeywell R7284U. This stupid thing will not power up the digital readout on the new primary control. The only way it works is if I straight wire a common and red to the primary control TT terminals.

A local contractor sold us a Beckett 7505A0000U primary control. Hooked it up and the furnace ran like a champ. I'm still not sure why the honeywell didn't work. I will say the local contractor said the ignitor wire goes to L2 and not the ignitor terminal.
