Gas-fired direct vent space-heating appliances used for providing heat in rooms for sleeping purposes shall be deemed to be located outside of the sleeping room provided that such a unit is factory assembled and manufactured with an integral factory assembled carbon monoxide detector interlock with automatic main gas shut-off valve. Such unit shall be of direct vent type, such that all air for combustion is derived from the outdoors and that all flue gases are discharged directly to the outdoors. All gas piping shall be hard-piped with no flexible connectors. Such unit shall be installed through a sleeve located in an exterior wall. Pursuant to Section 27-2034(f) of the New York City Housing Maintenance Code, each heater shall be equipped with an effective device which will automatically shut off the gas supply to the heater if its pilot light or other constantly burning flame is extinguished, or in the event of an interruption of the gas supply to the heater, and will not permit the heater to be relighted unless such shut-off device is first reset manually. Installation requirements shall be in accordance with the manufacturer's instructions and the applicable listing.
