The stove had been out for 2 days, & there may have been some chunks of bitty still floating around in there. So I fire it up last night, left the door open for a while, piled it on & closed the door. About a half hour later I told the wife to check on it ...... she says it looks like it went out. So I told her to open the ash door. Well, she let the ashpan area get real bright, then made the mistake of closing the ash door with the loading door shut.
BAM!!! I felt the house shake on that one! Wife screamed, so I asked if she's ok .... and she was. So I go down there in the fog of ash. I opened the loading door & another large explosion happened!
WOW! Never had one quite that powerful before!My glass is cracked COMPLETELY IN HALF!!! The mortar I put around the connector pipe where it meets the chimney is all cracked & loose, as is the pipe for the boiler. The new baro on the boiler pipe is no longer level. I swear the baro flap got bent slightly backwards, as it no longer sits flush when there's low draft. That was a biggun to be sure!!!
I have no screws in the pipe where it meets the stove & it didn't even move, as expected. It's wedged in pretty good -- & that was the ultimate test! Fire is burning bright right now. I overlapped the 2 halves of the glass. Not pretty, but will get me through the next few weeks until the weather gets more stable. Next season I'll either replace it or caulk it, depending on the finances.
Smitty, you might want to pull the pipe off your oil boiler and make sure you didn't get any flyash blown back into the heat exchanger. Also, since you are using a "combo chimney"...the next time you get ready to light the stove, try running the oil boiler for a while to warm the flue. My last house had a big flue, and it was tough to get the draft started in mild weather. 10-15 minutes with the oil boiler always did the trick
