I was at a home today which a while back had a lightning strike the chimney and explode the top of the chimney off. On the drive home I got to thinking, I have two metal chimney liners, one for a first floor wood-stove and another for the furnace and only the furnace liner is indirectly grounded, I guess, via the furnace ground. If TV antennas need to be grounded should chimney liners be grounded as well?
Thank you for your thoughts!
