I reciently move into a 29 year old log cabin. I would like to replace the original Olsen nat. gas furnace with a spiffy hi effency type.
My only issue is the "vent" that every one says has to be sloped back towards the furnace. The location [ kinda in the center of the main floor with no dirrect access to the great out doors] of the exesting furnace makes this impossible to do. What then are my options?
Please & thank you
