was sealing surround a good or bad idea?

[Mr. Jones]

I sealed it up with this fireblock sealant rated at 1,382 degrees f. Also sealed the bottom where air was rushing under the stove and up the chimney. I was having cold air problems in an old leaky house. The only issue I see with doing this is having to pull insert out when cleaning chimney. What say you?

I take it this is a slammer install? No liner attached to it?

 

[Grisu]

The way you describe your installation I suspect you have neither a liner nor a block-off plate. ( https://www.hearth.com/talk/wiki/make-a-damper-sealing-block-off-plate/ )
Put both in and you won't need the sealant, have less to no heat-loss, an easier to clean flue and a much safer installation.

 

[Mr. Jones]

Yea, it's a slammer. Didn't mean to load that pic soo big. I did it from my slow phone, and not sure how to get the pic thumbnail size.

 

[begreen]

I made the pic a thumbnail for ya. Slammers are no longer allowed. Time for a cleaning and liner.
