Cleaning a 6' Stainless Steel Liner for a wood fireplace insert
I have a lot of creosote build-up in my 6" flexible stainless steel liner. This is from last year, my first full season of using my insert. The liner is in a two story (21 ft. run) interior brick chimney which goes to a Regency I-300 Fireplace Insert. I just bought a 6" Rutland PolyPro round brush. This was recommended as opposed to a wire brush, as the wire may harm the liner.
It was also recommended that I first burn some logs (for a week) using some ACS (Anti-creo-soot) sprayed on the logs to crystalize the tar build-up in the liner prior to brushing. Your comments are welcome on this. Are there any other recommended anti creosote products out there?
But, most important, I tried to push the new brush down a remnant of the 6" liner that I had left over from the install. It is so tight, I wonder if I will have trouble in the cleaning process.
Seems like I will need to get the flexible 6 ft. poles to feed it down and up. I was going to use a rope method to pull the brush up and down. But, I'm afraid the rope may let loose, the the brush will get stuck... what a disaster that would be.
But I'm really concerned with how tight the brush is in the liner. Is this normal with chimney cleaning brushes.
What if the interior of the liner caught fire.... How dangerous is this? Would it safely burn itself out?
I'm here in the West Bloomfield area of Michigan (just north of Detroit) I'm a do it yourself kind of guy as I bought and installed the fireplace myself last November .
Looking foward to your comments in this critical area of wood burning.
