Stove Pipe Clearance Through Wall

We bought a 20 yr old cabin/cottage summer of 2013. It has a wood stove
with chimney pipe going through wall to exterior concrete block chimney.

The 6" black stove pipe goes through a 12" insulated pipe as it passes through
the wall (please see the photo attached). The Insurance comany has told me
that the 12" insulated pipe needs an additional 2" clearance all around. We ran
the stove all last winter and the 12" pipe never gets above body temperature.
It stays cool regardless of the intensity of fire in the stove. The former owner
assured me that in thet previous 20 years there was no evidence of any heat
from the chimney pipe on the drywall. So, why fix it if it ain't broken?

Should I go ahead and cut a 2" circle around the drywall to see if the 12" pipe
is clear of any structural members? If it is clear do I need to add any special
insulation before I throw a decorative metal collar over the gap I will create
in the drywall? Or, should I call a WETT technician to certify the safety of the
current installation? To me it all spells unnecessary $$$$$ down the drain.

Is the Insurance clerk just blowing smoke up my a** to simply watch me
jump through hoops?
Expert advice would be appreciated. GerryName:  Stove through wall.jpg

Hi Gerry,
The insurance clerk is probably right. The point you and the former owner missed is normal operation isn't want causes a fire in a wood stove chimney. If and when you get a chimney fire the temperatures can turn that black stove pipe cherry red, personal experience. Good intentions of keeping everything clean are not something upon which your insurance company wants to bet your house/cabin.

Be thankful they will even insure your cabin, in Maine it is becoming expensive to impossible to get insurance with a wood stove in the house or camp. Jump through whatever hoops they want and make them happy.
