[ASKNACHI]This question was posted on AskNACHI.org by Ted Hull (from Baltimore, MD). [/ASKNACHI]have an older oil furnace with Barometric Draft
Damper. The last time the unit was serviced, the
igniter was adjusted to prevent the access door from
blowing open during ignition. Even so, soot still
escapes from the draft damper.
Is there a way to filter the soot that the damper
spits out? Could a filter box be attached to the
damper (on the intake side)?
