In my opinion, installing a new line with the new boiler/furnace is smart. It adds little cost to the overall replacement and who wants a new boiler/furnace sucking on dirty line? Should the new unit have any issues drawing off the old line, you'll have to go back and take care of it...FOC, of course.Quote:
