Question about Heating & Cooling
Do you know how I could find the combustion air requirements for the subject model? I recently purchased the house and the former owners did not leave behind the owner's manual for the furnace. I am finishing the basement and need to ensure there is sufficient combustion air. Any suggestions?
The general rule is that gas furnaces need access to all of the air in a basement, so completely sealing off a utility room or closet is almost always a bad idea. Adequate air for combustion can be ensured by either installing vent high and low (both are important) in the finished utility room wall, allowing air from the rest of the basement to be able to flow into the utility room. These should be as large as possible, finished off with a regular return air register on the finished side of the wall. Another way of doing this is to install a louvered door for the utility room/closet, which will also give you enough air access for combustion.

Make up air is a different requirement than combustion air. Chapter 5 of the UMC states that if you have a dryer in a closet you need to provide a make-up air opening of 100 sq inches. The make -up air is to replace the air that is being exhausted not to provide air for combustion. The make -up air could be taken form the exterior of the building or another room within the building. Technically the closet should be insulated and weatherstripped if you get the make-up air and combustion air form the exterior.
Sorry doc john but the fire inspector is not talking about the exhaust duct (environmental air duct). That is required no matter where you have installed the dryer and is a totally separate
