I purchased a home a few years ago the had an HS tarm boiler model 303 with a coal automatic feed system attached. I have not been able to get any manuals on the feed system and tarm said they never produced one with an automatic system. The manual I purchased from tarm for this boiler has a reference to an HS 20 automatic stoker on page 2. Tarm again said they never seen it and would no longer be supported with parts or manuals anyway.
Is anyone familiar with this setup? I would need info on setup of system. I pressurized the boiler - no leaks- and the controls all seem to work properly. Any info on feed rate adjustment, air flow settings, coal type and size compatability would be appreciated.
