IPEX 196005 Installation Manual

These instructions are to be followed in conjunction with those
found in the IPEX System 636 Installation Guide. The installation
guide is available in every box of System 636 45° Elbows or
on the web at www.ipexinc.com.
System 636 Pipe, Fittings, Termination Kits and Cements are
certified as a system and must be installed as such. Different
manufacturers have different materials, joining systems and
adhesives. Do NOT mix pipe, fittings, cements, or joining
methods from different BH Vent manufacturers, this can result in
unsafe conditions and will void the certification.
System 636 PVC/CPVC concentric vent kits are made from
certified compounds. PVC kits are rated to 65ºC maximum and
CPVC kits are rated to 90ºC maximum.
All termination kits must be located and installed in accordance
with local building code and CSA B149.1 Natural Gas and
Propane Installation Code.

Concentric Vent Kit Assembly
1. Once the proper location has been determined, cut a hole
in the roof or wall large enough to accommodate the outer
pipe. The size of the hole can vary greatly depending on
the roof pitch.
2. As per the procedures outlined in the System 636
Installation Guide , solvent cement the inner pipe to the
concentric Wye fitting.
3. Solvent cement the outer pipe to the concentric Wye fitting.
4. Slide the assembly through the roof or wall penetration.
(Install flashing if needed)
5. To permanently affix the rain cap, it should be solvent
cemented to the inner pipe. For installations where removal
of the cap may be required for service or cleaning the cap, it
can be fastened mechanically (see instructions below). For
either installation method, the outer pipe is only a friction fit
with the cap.
6. Once the rain cap is installed, and the kit secured as outlined
below, the kit can be connected to the venting system.

Installation / Support Procedures
1. Kits must be securely fastened to structure, to ensure dimensions
shown below are maintained.
2. Straps are field supplied. Use straps, clamps or equivalent that
will not score or damage the pipe. Expansion and contraction
should be addressed between appliance and termination point.
3. 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.
4. The weight of the concentric kits must be supported by the
clamps/straps and not by the vent system it connects to.
5. Insulating exhaust piping in unconditioned space to prevent
freezing may be required by code.
6. For multiple horizontal installations, keep Concentric Vent Kit
gaps close (up to 4" apart) or over 24" apart.
These guidelines are not appliance specific; OEM manufacturers
may supply spacing guidelines particular to each appliance. In
this case the manufacturer's recommendations shall supersede
those described herein.
To prevent flue gas from recirculating, IPEX recommends installing
multiple concentric kits as follows:
2 concentric vent kits: either maintain a 24" minimum distance
apart, or have the rain caps no more than 4" apart
F
3 concentric vent kits: Option 1 - keep all 3 kits at least 24"
apart. Option 2 - group 2 kits close up to a maximum of 4" apart
and the third kit over 24" apart.
4 or more concentric vent kits: Option 1 - keep all concentric kits
at least 24" apart. Option 2 – group the CVK's in pairs, having 2
kits close together to a maximum of 4" apart, keeping the next
grouping of 2 kits over 24" away. As per Figure C.
The dimensions shown in Fig. C, are distances between the edges
of the rain caps.
7. The pipe length of the concentric vent kit can be shortened;

providing that the cutting and cementing procedures adhere to
the System 636 guidelines.
7.38 1.75
8. Pipe lengths and/or fittings can added to the socket of the rain
8.75 2.25
cap in order to divert the exhaust gas; providing that the
7.38 1.75
appliance manufacture confirms that the extra length or changing
in direction will not adversely impact the flow of flue gas

8.75 2.25 Mechanically Fastened Rain Cap
8.75 2.25 The Rain Cap must be installed with the supplied Stainless Steel
screwand lock nut, and in accordance with the instructions and
10.00 3.50
diagram below.
8.75 2.25
1. Locate the drill location dimple on the outside of the rain cap.
8.75 2.25
2. At this location, drill through the cap and the inner pipe wall.
8.75 2.25
Ensure that the path of the hole is perpendicular to the inner pipe
10.00 3.50
NOT the outside of the cap. For the 2" & 3" kit, drill a 3/16"
hole, for the 4" kit, a 1/4" hole.
3. Insert the screw and tighten the bolt, do not over tighten.
