d) Use straps, clamps or equivalent that will not score or damage the pipe. Do not constrain
or clamp the vent system anywhere between the Element and the vent termination point
such that it is unable to expand or contract as it heats and cools during operation.
e) The weight of the concentric kits must be supported by clamps/straps and not by the vent
system it connects to.
f) All penetrations must be sealed according to local building codes. Caulking for side wall
terminations and flashing for roof penetrations are typical. Use only PVC/CPVC compatible
sealing material, contact IPEX for a complete list
g) Attach the rain cap to allow for removal and cleaning according to section titled
Mechanically Fastened Rain Cap
. The rain cap can also be permanently attached to the
inner pipe with the solvent cement specified in the Installation Guide. Whether mechanically
or permanently attached, the outer pipe is only a friction fit with the cap.
h) Once rain cap is installed and the kit secured, connect kit to the venting system.
i) For multiple horizontal installations, keep Concentric Vent Kit gaps close (up to 4" apart) or
over 24" apart.
j) When installing three or more horizontal vents, consult the IPEX 636 installation manual.
k) Contact IPEX at www.ipexinc.com, if additional System 636 Concentric Vent Termination
Kit assembly or installation guidance is needed.
7.4 Connecting to an Existing Vent System
Do not connect the Element to an existing vent system until it has been confirmed that the
existing vent system complies with all requirements for a new vent system. A venting system in
full compliance with the instructions provided in this manual is required for safe and reliable
operation of Elements. Do not connect the Element to a masonry chimney.
W A R N I N G !
Before operating a unit connected to an existing vent system, confirm the vent system complies
with all guidance and requirements for a new vent system specified in this manual. Failure to
confirm the existing vent system complies can result in unsafe operation and the potential for
poisonous carbon monoxide to enter occupied areas and can cause property damage, personal
injury, exposure to hazardous materials or death.
