Hello, I have a jotul 550 that is located in the center of my living area. My chimney stack is masonry block with a clay liner that had to be broken/removed in order to make room for my insulated stainless stack.
I was having major issues with attic air coming down the chimney and out into my living room through the gap between the surround. The chimney liner connects directly to the top of the stove and runs to the top of my chimney.
Over the summer, a contractor poured insulation from the top of the chimney in order to 'plug' the area between the stainless liner and the rough masonry block in order to stop the attic air from down drafting into my living room. He stuffed fiberglass insulation above the stove and then poured the insulation in. It stopped the attic air and all was well until I started using the stove.
Now I can hear the pebbles dropping onto my stove while the stove is heating up/cooling down. Not a tiny amount either, it is piling up against the top of my stove and the flue pipe. To make matters worse, the insulation is falling into the space between the top of my stove and the box (where the air flows) and being blown out into my living room.
I had the contractor come back to address it, but all he did was put a small strip of fiberglass around the bottom of the flue and (to my dismay) taped it to my flue pipe with metal tape. Needless to say, I just pulled the surround to see why insulation is still blowing out and found the tape has failed (big surprise!) and there is a mountain of insulation laying on the top of my stove.
My question is, is it a good idea for me to stuff mineral wool insulation (rockwool) up into the space above the top of the stove and completely fill that void? (stuffed from the top of the stove all the way up as far as can go).
While i'm at it, can I also stuff rockwool on the sides/back of the stove to fill the gap between the stove and the 'fireplace'? I've attached some pics to hopefully help you visualize what I am talking about.
Thanks!
