furnace/heater in bathroom

[btuhack]

Both the Uniform Mechanical Code and International Mechanical Code prohibit a non direct vent fuel burning furnace and W/H in a bathroom, toilet room, or room for sleeping unless non DV appliance is in a separate closet with gasketed self closing doors and the closet must have the proper ventilation.

The main issue is that bathrooms have exhaust fans which can easily back draft a gravity flue. Even a dryer exhaust can back draft the furnace or W/H.

More likely the central heat was a retrofit. My dad installed a furnace in the home they bought when I was a teenager. Before that it was a fireplace and area heaters.
