ACCEPTED ENGINEERING PRACTICE
That which conforms to accepted principles, tests or standards of nationally recognized technical or scientific authorities.
A removable plate, usually secured by bolts or screws, to permit access to a pipe or pipe fitting for the purposes of inspection, repair or cleaning.
Having access to, but which first may require the removal of a panel, door or similar covering of the item described. See READILY Accessible.
An approved connecting device that suitably and properly joins or adjusts pipes and fittings which do not otherwise fit together.
The individual, official, board, department, or agency established and authorized by a state, county, city or political subdivision created by law to administer and enforce the provision of the code as adopted or amended.
AIR ADMITTANCE VALVE
One-way valve designed to allow air to enter the plumbing drainage system when negative pressures develop in the piping system. The device shall close by gravity and seal the vent terminal at zero differential pressure (no flow conditions) and under positive internal pressures. The purpose of an air admittance valve is to provide a method of allowing air to enter the plumbing drainage system without the use of a vent extended to open air and to prevent sewer gases from escaping into a building.
AIR BREAK (DRAINAGE SYSTEM)
A piping arrangement in which a drain from a fixture, appliance or device discharges indirectly into another fixture, receptacle or interceptor at a point below the flood level rim.
The treatment of air so as to control simultaneously its temperature, humidity, cleanness, and distribution to meet the requirements of a conditioned space.
AIR GAP (DRAINAGE SYSTEM)
The unobstructed vertical distance through the free atmosphere between the outlet of the waste pipe and the flood level rim of the receptacle into which the waste pipe is discharging.
AIR GAP (WATER DISTRIBUTION SYSTEM)
The unobstructed vertical distance through the free atmosphere between the lowest opening from any pipe or faucet supplying water to a tank, plumbing fixture or other device and the flood level rim of the receptacle.
That portion of an injection (Bunsen) type burner into which the primary air is introduced.
An adjustable device for varying the size of the primary air inlet or inlets.
ALTERNATIVE ENGINEERED DESIGN
A plumbing system that performs in accordance with the intent of Chapters P3 through P13 and provides an equivalent level of performance for the protection of public health, safety and welfare. The system design is not specifically regulated by Chapters P3 through P13.
In a choice of two code provisions, signifies that use of both provisions will satisfy the code requirement and use of either provision is acceptable also.
A term applied to valves or mechanical devices that eliminate siphonage.
Any device which utilizes gas as a fuel or raw material to produce light, heat, power, refrigeration, air conditioning or to generate a chemical atmosphere.
The flue passages within the appliance.
APPLIANCE, AUTOMATICALLY CONTROLLED
Appliances equipped with an automatic burner ignition and safety shut-off device and other automatic devices which accomplish complete turn-on and shut-off of the gas to the main burner or burners, and graduate the gas supply to the burner or burners, but do not affect complete shut-off of the gas.
APPLIANCES FOR VENTED FIREPLACE
A self contained, free-standing, fuel-gas burning appliance designed for installation only in a vented fireplace and whose primary function lies in the esthetic effect of the flame.
APPLIANCES FOR VENTED FIREPLACE Coal basket
An open-flame type appliance consisting of a metal basket filled with simulated coals which gives the appearance of a coal fire when in operation.
APPLIANCES FOR VENTED FIREPLACE Fireplace insert
Consists of an open-flame radiant-type appliance mounted in a decorative metal panel to cover the fireplace or mantel opening and having provisions for venting into the fireplace chimney.
APPLIANCES FOR VENTED FIREPLACE Gas log
An open flame type appliance consisting of a metal frame or base supporting simulated logs.
APPLIANCES FOR VENTED FIREPLACE Radiant appliance
An open front appliance designed primarily to convert the energy in fuel gas to radiant heat by means of refractory radiant or similar radiating materials.
a person learning a craft under a skilled person; A beginner.
Approved by the gas official or other authority having jurisdiction.
A receptacle designed to collect surface or storm water from an open area.
A fitting or device supplied with water or other fluid under positive pressure that passes through an integral orifice or constriction, causing a vacuum. Aspirators are also referred to as suction apparatus, and are similar in operation to an ejector.
AUTOMATIC GAS SHUTOFF DEVICE
A device constructed so that the attainment of a water temperature in a hot water supply system in excess of some predetermined limit acts in such a way as to cause the gas to the system to be shut off. It may be constructed integrally with the shut-off device or be a separate assembly.
Means which provide for ignition of the gas at the burner when the gas burner valve controlling the gas to that burner is turned on, and which affect re-ignition if the flames on the burner have been extinguished by means other than closing the gas burner valve.
