Insert exhaust

[robweinrich]

New to all of this. Just curious. With an insert, how come you have to run tubing , why couldn’t you just have the flue open to allow the smoke to escape?

Dumb question I’m sure. Don’t judge.

Thanks,

Because just allowing it to vent into the fireplace allows the exhaust to cool off to much. That creates creosote and reduces draft which makes more creosote. The insert also is not sealed to the face. That allows dilution air in which makes the problems worse.

The other problem Is when all that creosote catches fire air leaks around the insert feeding massive amounts of air to the fire

Now, this never entered my mind
