Re: Water Heater Location
From the 2003 IRC:"M2005.2 Prohibited locations.Fuel-fired water heaters shall not be installed in a room used as a storage closet. Water heaters located in a bedroom or bathroom shall be installed in a sealed enclosure so that combustion air will not be taken from the living space. Direct-vent water heaters are not required to be installed within an enclosure."From the 2003 IMC:"303.3 Prohibited locations.Fuel-fired appliances shall not be located in, or obtain combustion air from, any of the following rooms or spaces:1. Sleeping rooms.2. Bathrooms.3. Toilet rooms.4. Storage closets.5. Surgical rooms.Exception: This section shall not apply to the following appliances:1. Direct-vent appliances that obtain all combustion air directly from the outdoors.2. Solid fuel-fired appliances, provided that the room is not a confined space and the building is not of unusually tight construction.3. Appliances installed in a dedicated enclosure in which all combustion air is taken directly from the outdoors, in accordance with Section 703. Access to such enclosure shall be through a solid door, weather-stripped in accordance with the exterior door air leakage requirements of the International Energy Conservation Code and equipped with an approved self-closing device."
The important part of the above code is highlighted (bold) to identify that the combustion air shall not be taken from the living space. Clearly, if there is a door that opens into the sub-closet and the closet opens into the bedroom-- this is not a good install.
