Block off plate, insulate the top of the chimney....ect..

[Dustin]

I'm installing 20 feet of SS Simpson Duraflex liner in the morning to my older Osburn insert. The liner calls for 1'' clearance from the masonry chimney

I live in Northwest Oregon. During the winter the temp usually hangs out around 40 degrees. Sometimes it will drop below freezing but not very often. Mostly just 40 and RAINING all freakin winter.


Anyway, I'm obviously going to seal the chimney off with a top plate.

This house was built in 1970, and has an interior brick chimney with a HUGE hearth. It takes up the entire wall in the living room. The chimney is large and has three individual flues.

The one I'm installing 12''x12''

In our pretty mild climate, is it worth it to put a block off plate in above the insert, and insulate anything?

Thanks
Dustin

Since the chimney is interior you could get away without insulating the liner.
However, I think you will regret not doing a block off plate. Ya gonna save alot
of heat from escaping up tha chimney (resulting in less wood usage) and being more comfortable.

Edit: Not to mention if you DIY it will only cost about $15.
