TRAP SEAL
a cylindrical conduit or conductor or conforming to the particular dimensions known as “tube sizes” and denoted by its outside diameter or O.D
TUBE
a room space having a volume equal to at least 1.4 cu.m. of the aggregate input rating of the fuel-burning appliance installed in that space. Rooms adjacent and open to the space where the appliance is installed, through openings not furnished with doors, are considered a part of the unconfined space
UNCONFINED SPACE
an arrangement of venting so installed that one vent pipe will serve two (2) traps.
UNIT VENT

VAClJUM BREAKER
a pipe or opening used for ensuring the circulation of air in a plumbing system and for relieving the negative pressure exerted on trap seals
VENT PIPE
the vertical vent pipe installed primarily for providing circulation of air to and from any part of the soil, waste of the drainage system
VENT STACK
pipes installed to provide flow of air to or from a drainage system or to provide a circulation of air within such system to protect traps seals from siphonage and back pressure
VENT SYSTEM
any pipe or fitting installed in a vertical position or which forms an angle of not more than forty-five (45) degrees with the vertical line
