What Coal Should I Burn in EFM 700,900

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.

If it says S30 on the blower and is 16" across the pot, the stoker came out of an EFM 700. The stoker can handle rice, rice/buck mix, or straight buck. Since you can only get rice it is an easy decision. ;)

it does say S30 on the blower, what is the difference of the 700 and the 900 ? how do you tell? does burning the rice coal mean I will use more than buck?

IF IT SAYS S-30 IT IS AN E.F.M. unit as far as the boiler it should have a plate or a stamp
, G.M.C. or LOLINE,COBCO OR FITZGIBBONS these were all boilers used by E.F.M. where is the domestic coil located, is there a cleanout plate under the coil, round or square fire door SCRAPPER
