If you're talking about the "holes" in the heatilator, of course
it would be bad to plug them! I'd suspect it'd be bad to plug
ANY hole unless you're positive what you're doing. Your descrip
is very lacking in the place where high detail is needed; sorry.
A heatilator works by extracting the heat from the air before
it goes to the chimney, but ... it can't make the air cool
Is it functioning OK? I'd leave it alone if I were you except
to possibly oil any oil ports if the motor has them and be sure
the cord is in good condition.
Perhaps if you more closely described where the "holes" are, what
they're in, and what are they between, etc.?
Oh, BTW, heatilators also, by their nature, make the air going
up the chimney cooler than usual and so creosote and such builds
up much faster. Using a "roaring fire" to clean a chimney,
especially when one is using a heatilator, is a dangerous
situation. Only clean it the right way. \\
