EFM-520 Build Thread

Stoker Coal Boilers automatically feed the coal and have controls and pumps just like any conventions boiler. They are intended to be used as a primary heat and often have domestic hot water coils as an added bonus. They can be set up independently or in dual sytem with your existing oil/gas boiler. They can accommodate both hot water base board or steam plumbing.

Actually I took the baro off a while ago, the second day of running the unit and havent put nit back on since. I suspected I did not have adequate draft so I put a cap in its place to play it safe. The manometer mesurement was taken with the cap in place and is still at .02 to .03 witch I understand is ok for this stoker but .04 is best. I will see when it gets cold if draft gets better.

If the draft in the chimney improves and you don't have the damper adjusted, you'll have a little blast furnace in your house.

Thanks for the warning stoker man. I mounted the manometer permanently so I can moniter the draft because I don't know what to expect with my new install. Last night I had .01 when not running and .03 when running. By the way, really nice to meet you yesterday at the meet and greet. Wist I lived closer so I could help with your pipeing project.

If it's negative .03 at the door when running, it should be reduced via the damper to neg. .02. I'll let you know if my system leaks........if it gets done this year.
