I have a DGA070 furnace in my mobile home. When it runs, it draws air from the house, mainly through the fireplace chimney. It seems to be when the big fan is running, not the burner fan.

I figured the big fan was just moving air around. I don't see why it should pull a negative pressure on the house.

It will pull all cold return air throughout the home. IF the fireplace is open and/or not sealed, it will pull air from there as well.


Thanks,
Robert
