I feel your pain smitty...
The new DS stove just got fired for the first time on Sunday...
Had four good booms...
One when opening the glass door to get a 'look see'...
Baby Boom...
One just because it could...
Muffled boom...
That tested all the black pipe, stove was closed up and all the pipe joints have 3+ screws...
Another to see how the hopper door worked...
Boom...
The best was like yours...
New coal, hot fire and opening the ash door forgetting to open the over fire air...
Heard the woooooof-boom, then the ash cloud...
That was the biggest as I was getting close to a full load of coal...
These puff backs can be huge as the new stove can hold about 165# of coal...
I am not an engineer, train or otherwise!
I stay at a Holiday Inn at least once a year!
Most of all I do have common sense and a practical application of logic.
Oh, add humor, on the dry side, along with a wee bit 'o sarcasm.

I also had a nice size sonic boom from my DS #3. I forgot to open the over fire air after loading it over the top. About 5 minutes later I went to check on its progress. Well I had blue flames come out the door at least a foot. The fly ash exited all the pipe connections and the clean out door blew open. But the funniest part is the cat will not go near the floor register at all any more. The wife said when she heard the boom she jumped but nothing like the cat, straight up in the air and then off to the back bedroom for a few hours to recover.

Glad you all enjoyed! I laughed my ass off too ...... the wife didn't seem to find the humor in it ... until some time passed. :lol:

She's a trooper though .... I got her to get her motorcycle license after I bought her a 1984 Honda XL350R ..... I thought that would be a good beginners bike. I guess I've been riding too long! :lol: She rode the best wheelie I've seen in many years .... completely out of control!! Almost ended up in my neighbors living room, bike & all ..... but that's another story for another day! She got back on the horsey (not the same one though) & got her license!

So I'll get her tending to the coal fire again ... :devil: :funny:

At least I know my chimney is clean! :woot:

My barometric damper blew out with a bang! After the second time I switched to nut coal and no more problems. Left the damper out and seems like don't need it on this stove. Warmer without it.

Ok. I know this is probably explained someplace else in the forum but as I am new; what's the mechanics here? Why does it happen? Pressure? I have a Mark III right in the middle of the house. This sounds like something I could lose my bladder over. :gee:

It happens when you pile fresh coal on top of a nice glowing bed .... now the flame goes out, but the fresh coal starts heating up & releasing flammable gasses. Sometimes just the pressure of shutting the ash door will force a tiny flame through a corner of the bed of coal ...... and since you just had the ash door open, you now have a perfect air/fuel mixture .... essentially, you've created an engine with no piston! :D

This is completely preventable. Little bit of coal at a time, or banking the coal ... or opening both the ash & loading doors at the same time until you get flame, then close ash door first, followed by loading door ..... if there is no flame, the potential for a puff is high. If you have flames, no chance at all. 8-)

I see this scenario every day. Just a matter of time I suppose. Mine is usually banked quite a bit though since I usually fill it above the fire bricks in the back. I keep it between 1/2 to 1 1/2 turns and I need a lot to last the 12+ hours I am away during the day.
