We have used them on pellet stoves (which have their own id fans) to
limit draught on an insulated ss chimney that rose through 4 floors. I
wasn't entirely happy with the idea as it raised the possibility of
the boiler room getting combustion products if the seal wasn't good, I
would have been happier if the air was sucked from outside. In fact
there was subsequently a problem but this was down to poor
maintenance.
