After fire inspection pics...and Q's...

[WhatIsChazaq]

Inspecting the stove...this is what I found:

It all looked very clean inside, but with a dusting of ash.

This is the oval adapter, the yellowish color in the pic is from the work light I was using.

Here is the oval vent on the back of the stove. Shouldn't the oval vent adapter be cemented...or at least screwed into place?

Looking up the vent stack through the ceiling box:

I didn't see any creosote whatsoever...I mean NONE. All the metal looks nearly new (plus the ash dust). I didn't really notice any discoloration of the metal ("bluing") except at the adapter ring that connects the internal vent piece (black pipe) to the ceiling box.

Is it possible that when the Everburn was running really hot...an extra injection of air at the oval adapter (because it wasn't sealed) was acting like a jet afterburner and hitting Mach 6 as it tried to exit the stack?

Shouldn't the oval vent adapter be cemented...or at least screwed into place?

It looks like you have screw holes in that cast iron stove collar. The screw holes are for screws into single wall pipe but with a straight piece of double wall with a slip joint I see no need for the screws. My stove doesn't have screws or cement at the collar and the vertical piece of double wall is expanded into place and screwed to hold it expanded.

I passed inspection and pro installation with no collar screws and I pointed it out to both guys.

Seeing fire at the collar means it wasn't on all the way. That's bad.

I like a system to be as rigid and held together as possible, so I screw at every opportunity. That includes at the flue collar. After a couple of strong puffbacks, and/or earth shakes you'll see what I mean.

I hesitate to say "never"...so I'll say that earthquakes and Southern Colorado don't go hand in hand.
