303.3 of the Uniform Mechanical Code lists prohibited locations for a heating appliance. There are exceptions if the stove is very small or the room is really large.
Okay, I understand that the whole Art of the Code is
Interpretation, so I will not be super critical here, but you are referring to the Uniform Mechanical Code, which regulates the installation of "mechanical systems," and which I had not been aware had any bearing on (non-mechanical) wood stoves.
If I accept as a given that it does, in fact cover wood stoves, then here is the text of the subsection you posted:
303.0 Installation.
303.1 Installation Practices.
Mechanical systems shall be installed in a manner in accordance with this code, applicable standards, and the manufacturer’s installation instructions.
303.2 Listed Appliances.
Except as otherwise provided in the code, the installation of appliances regulated by this code shall be in accordance with the conditions of listing. The appliance installer shall leave the manufacturer’s installation and operating instructions attached to the appliance. Clearances of listed appliances from combustible materials shall be as specified in the listing or on the rating plate.
303.3 Room Large in Comparison to Size of Equipment.
Central-heating furnaces not listed for closet or alcove installation shall be installed in a room or space having a volume not less than 12 times the total volume of the furnace; central-heating boilers not listed for closet or alcove installation shall be installed in a room or space having a volume 16 times the volume of the boiler. Exception: The installation clearances for furnaces and boilers in rooms not large in comparison with the size of the equipment shall be as specified in the appliance listing regardless of whether the enclosure is of combustible or noncombustible materials and shall not be reduced by the protection methods described in Table 303.3(a1) or any other method. Where the ceiling height of the room or space exceeds 8 feet (2438 mm), the volume shall be calculated on the basis of an 8 foot (2438 mm) height.
I would note that the rest of this section refers to obviously mechanical equipment, such as rooftop condensers, that Chapter 3 overall refers to solid fuel devices only in tables that list approved clearances from combustible materials, and that section 305, which states that,
"Heating appliances shall be equipped with a listed device or devices that will shut off the fuel supply to the main burner or burners in the event of pilot or ignition failure," there is absolutely no mention of solid-fuel heating devices, either as covered entities, or as exceptions, while all other types of mechanical heating devices are mentioned.
Section 303.3 clearly applies only to central heating furnaces, which are mechanical devices, and not to non-central heating accessory appliances.
However, even if I were to accept that the wood stove in question were a central heating furnace (which it is not), at roughly 12cu/ft, if we multiply its volume by 12, we get 144cu/ft, which is 1/24th the actual volume of the 3500cu/ft room in which I intend to place it, and therefore well within the requirements of this section (which doesn't apply to it anyway).
Do you have any other references?
