I just bought this used NewMac NBR-2000 wet base design oil fired boiler. The seller said it was 8 years old. I've since found out from decoding the serial number it was made in 1997. Even so it is...

Thanks for the advice.
I thought the main jet was clear. Turns out it was partially plugged. I got it cleared and the generator would run with the choke open. However it was surging like crazy. I...

I'm pretty sure the firing rate of a coal fired stove or boiler is based on the floor area of the firebox and the open area of the grates. I haven't found the formula yet.

The draft is only open 1mm, at 8 degrees F outside, 72 inside the boiler water temp around 107 degrees. Not much room to close it.
