Yeah, after thinking about it now I'm covinenced it's a 2 into 1 config. I wont know 100% until I can get on the roof and look down the flu to see if they are seperate all the way to the top of the chimney and just "share" the same opening at the top.
I do know that prior to hook up of the stove to the piping, I stuffed a t-shirt in my "T" to keep from pulling the heat out of the house and it damn near pulled it into the "T" all the way.
Also, when the furnace kicked on, the draw through the piping increased big time! thats why I installed the hand damper thinking I needed to slow down the air drawing up and out.
So it look's like I'm stuck being only able to burn wood in the stove not coal because of the fireplace/chimney/furnace configuration that right?
Does a wood fire need that much less a draft then a coal?
Obviously I can burn wood there It'S connected to a fireplace. Lucky for me I guess The Russo c35 is a wood/coal stove
I was hoping to get that roast you out of the house heating effect from burning coal with the long burn times. Unlike wood... stoke the stove every 2-3 hours looks like I need to warm up the chain saw......
If anyone has any other insight on if my config will work for coal please speak up.
