I was recently sold into buying and installing a pull-type chained damper
that is connected to the roof with the chimney cap. This is to replace our
rusted old damper inside the lower area of the chimney.
I've never had a fireplace, but I was a bit hesitant into buying because I
think I would like to visually see if the damper is closed.
Can you give me your unbiased opinion on the advantages and disadvantages of
the top chimney cap mounted damper vs the type that rests inside the
fireplace directly over the fire?
