I have a Lopi "revere" certified insert. I have seen at least one
comment about insulating the hidden part of the stove to cut the
loss into the chimney. I have a stainless chimney liner from the
stove through the top of the chimney. Does anyone have any
knowledge about the advisabilty of this action. I would probably
use 1" insulation from the stove shop, backed up with standard
fiberglass insulation to hold it in place.
