Forever Flex Chimney Liner

[Siggy894]

Last year I installed a Regency CI1250 wood stove insert with a 5.5” forever flex chimney liner in an existing masonry fireplace with a heatilator preform metal firebox. I installed a 5.5” forever flex chimney liner with the blanket insulation around it. To get the chimney liner to come down I had to cut out the old damper and some of the smoke shelf. My only question now is there is bend in the chimney liner to get it from the back of the fire place to where it hooks into the woodstove. Is it okay for a chimney liner to bend like this or should I install an offset box on the top of the stove that would connect to the chimney liner? I would like to figure out if this is okay so I can move onto making a block off plate. Thanks

They make 15 and 30 degree angled appliance adapters.

At this stage of the install, maybe just get the angled appliance mentioned above. That way, the adaptor fits in stove nice, straight, and tight.

The manufacturer of the stove also sells an offset flue adapter that would set the center of the flue back another 5”. Maybe it’s best to go that route?

You have 5.5” liner (undersized) if you are not over 20’ the offset box will further reduce draft. I vote adapter. But it’s hooked up and the liner didn’t come apart making the connection so not working, correct. Are you just not like the looks or are you trying prevent something?

The manufacturer of the stove says 5.5” or 6” liner is acceptable with this model stove. It’s not an offset box, it’s an offset flue adapter that manufacturers sell. I installed everything last year and was able to burn only a few times. The draft was good with no problems. My only concern is if it is okay for a s.s chimney liner to flex that amount to hook into a stove? I just want to make sure everything is good before I go ahead and install a steel block off plate.

You need to unwrap the lower insulation and inspect inside and out for separation. I’m assuming It came in a box. Is the radius tighter own than it was in the box? It doesn’t look to extreme but I’d unwrap just for piece of mind. If it’s fine wrapt back up and leave it alone.

No it is not bent as tight as it came in the box. I just has a S curve to it. Here is the part the manufacturer offers to help get rid of that. If you look inside the firebox the liner comes down and is flush with the appliance connector.

Bends are fine. Unwrap if you to be extra sure it’s good to go. otherwise I would not mess with it.
