copped a Riteway M37. tore it down today. found some interesting stuff. this one was burned pretty hard. the bottom around the edges were full of nails. someone was burning scrap wood in it. also found quite a few pieces of partially burned coal, so they burned that too. louvers were installed upside down in anthracite coal burn mode, and they were blocked with coal ash. one brick retainer was broken in half on a short side, and 2 bricks cracked.
the thermostat and magnetic damper work perfectly. chain is intact. direct draft damper works perfect too. fire door is missing one bolt/nut, and the emblem is gone leaving 2 tiny holes. no front or rear exterior heat shields on this one. now the real hard core coal addict stuff you never find out, until you tear one down.
shining a very bright flashlight directly down into the combustion flue, from the direct draft outlet pipe area, and looking down at the bottom main draft inlet valve area, with thermostat set wide open, I could see a slit of light down inside the main draft control box. the main draft was leaking and directly exposed to the exhaust flue gas portion above it, through a little slit
, most likely between the 2 firebricks that are angled to form the combustion flue at mid level in the firebox. doubtful its a design feature, most likely an overlooked quirk in the stove design that needs to be fixed.
not good. since when is main draft exposed to exhaust flue, when there is already secondary air holes drilled in that area, with a cover on them.
deduction is this stove was leaking main draft into the exhaust flue and probably didnt respond to the control valve very well. I'm going to remove the entire direct draft assembly next. the combustion flue will have to be sealed with furnace cement or gasketed.
just an fyi to those who own this stove or one of its modern clones or variants
ok heres the pics. to know how any stove works, take it apart and look at it first. this thing has a massive firebox. these stoves are a neat design. I like the removeable top. already thinking of modifying it, to make it a TOP LOADER like a cook stove or old oak stove.
