(f) Fresh air intakes may also be installed within existing unused chimney spaces providing acceptable spacing and clearance is obtained
at the termination as per appliance manufacturer requirements.
(g) Vertical piping through the chimney space or any other vertical spaces exceeding 20 ft (6m) is to be structurally supported by use of a
pipe coupling installed immediately above and sitting upon a snugly fit pipe clamp. One of these pipe coupling and pipe clamp
combinations is to be installed at the entrance of the chimney space to support the pipe weight. The clamp at the entrance of the
chimney is to be rigidly fixed against the wall or floor (see Figure 4). Should the pipe run exceed 60 feet (18 meters) inside the
chimney space, please contact IPEX for further guidance.
(h) It is recommended that consideration be given to obtaining an air-tight or water-tight seal as required at the chimney exit to prevent
entry of water, snow, moisture or cold air.
(i) The use of System 636 Deep Socket Couplings is recommended when available for added joint strength for chimney installations.
