Small Puff Of Smoke Came Out Of Collar Connector?

Hi, I did do some searching for this topic and got some good info but it wasn't really exactly related (I don't think) to what I'm wondering about here.

At first I thought I was just seeing something in my imagination but from time to time I see a small puff of smoke come out of the collar connector on our stove. This only happens when a reloaded stove reignites. In other words when we have a good glowing bed of coals on and then load the new load, the stove smolders for a few seconds and then ignites in a woosh and right at that point a puff of smoke sneaks out of the collar connector.

I think this is happening just basically because with that woosh of ignition the interior air pressure of the stove rises significantly for a fast second but is it something to address or to ignore? If it is something to address are there any recommendations about how? I've read through several threads and I think I've learned that I wouldn't want to use any sort of silicon type sealant but instead something similar to Rutland's stove cement? Then again I've also read through several threads and I think I've learned that I shouldn't really need this at all? So I'd love to get advice about all this. Thanks as always.

PS This is with ICC's Ultrablack Double Wall Stove Pipe going to ICC's Excel Double Wall Chimney Pipe if that is helpful to know. Thanks Again.

Sounds like a small puffback as the built up wood gas ignites. To avoid this I like to put a few shavings, nut shells or thin scraps on the coals before putting on the splits. These ignite quickly. Also, you can ignite the smoke with one of those long barbeque lighters instead of letting it build up.

Yes that is exactly what it is right when the wood ignites it does this and I wasn't putting smaller pieces in so it sort of built up big amount of smoke for say fifteen or so seconds and then ignited pretty powerfully. So you're saying it is better to basically just put some smaller pieces in to prevent this as opposed to relying on furnace cement? Thanks.

Furnace cement is not the solution for this. The solution for this lies in the operation of the stove.

Understood! I will start adding some kindling to the bed and then add the splits to avoid the ignition that pressurizes the stove. Thanks as always for all the advice.
