So i picked up a 4 year old Hitzer 50-93 this January and Installed it.
New to coal burning, so far love the heat and the duties of maintaining it.Info:
Hopper gasket replaced, all others passed dollar bill test.
2200 sq ft ranch home built in mid 60s and well insulated.
Stove is located in mostly finished basement.
Chimney is SS rocket outside of home 18' tall
Using cheap baro because that's what was used on the stove when i got it, and recommended from last owner.
Manometer installed, reading .05-.06 baro open about 1/3.
Magnetic temp sensor on pipe right below baro and top right corner of stove.
Variable speed controller for blower (usually set at half speed or a bit less).
I ash down and fill every 12hrs.
Normal temps pipe: 180-225 stove: 350-450 nut coal
pipe: 150-200 stove 350-450 pea coal
2 CO detectors in basement.
I started with Kimmel nut coal cause it was bagged and I only had to drive 5 miles to get it.
I burned for about 3 weeks with no issues, thanks to all the info on this forum. Then one morning I emptied ash pan, It had a medium burn going, shook it down till i had coals in pan,(rear flap was open calling for air) and within 10mins or less the stove pipe started to rumble and temp shot up to 550.
It filled basement with paint smoke. I shut the back flap, opened the basement door and nervously waited for temps to come down. Once temps dropped to under 200 I adjusted dial rear flap opened and it happened again only reaching 500. So now I'm late for work and I continue to do this till pipe stays at an unnerving temp so I can leave (about 2 hours).
It was fine for a few days, no issues, then all of a sudden one morning it happened again. I let it burn out, shut it down, cleaned everything, checked everything, started a new fire.
It was fine for a few more days, I went to pick up some coal and *censored*, they sold out of nut. I grabbed the last 5 bags of pea and have been using that. I found pipe temps to be lower with same stove temps. Then just this morning, shakedown ad pipe temps shot up to 400.
Can anyone tell what I might be doing wrong? I'm sure it is me and not anything else. Anything I can do to avoid this? I hate being late for work and thinking about the damn stove all day.
