It seems very clearly to come from vents in one part of the house, and if you walk by the heater when it is coming out from the vents the heater does smell.
We have had the heater checked out, and he could find nothing wrong. The gas company has checked for gas and CO, and they found nothing. We've had the vents cleaned, and it still happens.
HELP!
Thanks.
