System 636 Installation Methods
2
(d) Only certified System 636 PVC or CPVC primer and cement shall be used to assemble System 636 PVC or CPVC venting systems.
* All IPEX System 636 cements contain special additives to aid in identification during warranty claims.
NOTE: Follow IPEX solvent welding procedures as shown in this manual, and check for proper joint construction when joining pipe
to fittings.
(e) Venting should be as direct as possible with a minimum number of fittings. The maximum vertical rise or horizontal run of vent pipe
plus the total number of fittings in a single vent installation shall not exceed the requirements outlined in the appliance manufacturer’s
installation instructions.
(f) All framing requirements for floor and ceiling penetrations shall be in accordance with the local building code and/or the local
regulatory authority.
(g) All penetrations of fire rated floors and walls shall be firestopped as described in Section 7 of this manual.
(h) Roof penetrations should be sealed with a plumbing roof boot or equivalent flashing as per the local building code, or as
permitted by the local regulatory authority.
(i) Chemical attack can cause product failure. Only use PVC/CPVC chemically compatible sealants, gaskets and adhesives.
(j) If spray foam insulation comes in contact with System 636, it is recommended that foam be applied in a maximum layer thickness
of 2 inches (50mm) until the required thickness of insulation is achieved.
(k) All horizontal sections of the venting system must be installed with a slope not less than 20mm/m (0.25 in./ft.) down towards the
appliance in order to collect condensate and remove condensate generated inside the line. The removal of condensate will help
reduce the possibility of ice buildup and blockage. Refer to the appliance manufacturers' installation instructions for further details
regarding the installation of necessary condensate drains.
