Good morning all,
Just finnished up a hybred out of Mike's (pacway) International boiler,a 350 base,and my 520 stoker.
She is working very nice.
My question is, what should I be seeing for a baro reading at idle ?

Hope this is not a stupid question. :?

Thanks !
Dave

Somewhere between -0.01 and -0.05" of w.c. should be fine. if there isn't enough draft, you will need to either modify the chimney, or add a draft inducer.

Sounds like a great setup.

Thank Rob,
I like the tubes in the fire design that they had. And the way the door opens makes for easy cleaning. She was tall and that made the lift up onto the base tough but its nice for thermo- reserve, ( lots of gallons ) on early morning showers with girls in the house. :o

I'd recommend permanently installing a manometer to monitor Draft at all times before your barometric damper. It is a valuable diagnostic tool.
