We have a 90s three story townhouse, and our ground floor has the garage, foyer and family room.
In our layout, the garage and family room span end to end of ground floor. The gas water heater and furnace are in a small utility closet between garage and family room.
But in our configuration, the garage is closed off and the utility closet has a gusset red vent door to the family room.
1) does anyone know why they put our gas appliances in our family room? Would it be possible to open the other side of the closet to the garage and close off the family room?
2) how many people have gas appliances in their finished basement or den, and do you let your kids play down there unattended? Does air quality suffer, like NOx or does the flue catch things really well?
