Pulled the stove pipe and stove pipe adapter off to inspect the bottom of the chimney and found a small hole in the stainless steel chimney. The contents between the inner liner and outer covering is a white powderish material. Wondering if I have to replace that piece of chimney or if a piece of foil tape to cover the hole would be enough to prevent anymore insulation from falling out. This wood stove was installed by my father-in-law at least 25 years ago and hasn’t ran in the last 15 years. The top of the wood stove has rusted from years of neglect and I’m trying to determine if it worth repairing/replacing or come up with another heat source.
