"Accessible" is having access to a fixture, connection, appliance, or equipment that requires the removal of an access panel, door, or similar obstruction.
"Appliance compartment" is a room having a floor area not in excess of twice the largest plan area of the room's appliance or appliances plus clearances required in this chapter.
"Automatic pilot device" is a device employed with gas-burning equipment that will either automatically shut off the gas supply to the burner being served or automatically activate, electrically or otherwise, a gas shutoff device when the pilot flame is extinguished.
"Btuh" is British thermal units per hour.
"Clearance" is the distance between the appliance, chimney, vent, or chimney or vent connector, or plenum and the nearest surface.
"Combustible material" is a material adjacent to or in contact with a heat-producing appliance, vent connector, chimney, or steam and hot water pipes, made of or surfaced with wood, compressed paper, plant fibers, or other products that will ignite and burn. Such material must be considered combustible even though flame-proofed, fire-retardant treated, or plastered.
"Connector-gas appliance" is a flexible or semi-rigid connector listed as conforming to ANSI Standard Z21.24, Metal Connectors for Gas Appliances, used to convey fuel gas, three feet or less in length (six feet or less for gas ranges), between a gas outlet and a gas appliance in the same room.
"Fuel gas piping system" is the arrangement of piping, tubing, fittings, connectors, valves, and devices designed and intended to supply or control the flow of fuel gas to an appliance.
"Gas" is fuel gas, such as natural gas, manufactured gas, undiluted liquefied petroleum gas (vapor phase only), liquefied petroleum air-gas mixtures, or mixtures of these gases that would ignite in the presence of oxygen.
"Gas-supply connection" is the terminal end or connection to which a gas-supply connector is attached.
"Input rating" is the maximum fuel-burning capacity of any warm-air furnace, recessed heater, or burner expressed in British thermal units per hour.
"Liquefied petroleum gases (LPG)" is any material that is composed predominantly of propane, propylene, butanes (normal butane or isobutane), and butylenes, or any mixture of them.
"Quick-disconnect device" is a hand-operated means of connecting and disconnecting a gas supply or connecting gas systems and is equipped with an automatic device to shut off the gas supply when disconnected.
"Readily accessible" is having direct access without the necessity of removing any panel, door, or similar obstruction.
