2.8. 1 Installation Methods for IPEX System 636 Type BH PVC or CPVC Gas Venting Systems (for Canada Only)
System 636 PVC or CPVC Type BH Gas Venting
Systems are third party certified to ULC
S636.The following installation methods have
been prepared in conformity with the require-
ments of section 4 of ULC Standard S636.
1. Application
IPEX System 636 PVC or CPVC Gas Venting
Systems are intended for negative or positive
pressure venting of gas fired appliances
producing exhaust gases having temperatures
limited to the range specified in 1(a) and 1(b).
(a) System 636 CPVC venting systems are sui-
table for temperatures up to and including
90°C (194°F); ULC S636 Class II.
(b) System 636 PVC venting systems are suita-
ble for temperatures up to and including
65°C (149°F); ULC S636 Class II.
2. Limiting to Use and Application
(a) Improper installation of System 636 CPVC
systems may result in personal injury or
death. Only qualified personnel should
attempt the installation of gas burning equip-
ment, following the gas appliance manufac-
tures' directions.
(b) All System 636 gas venting pipe and fitting
must be carefully inspected before use to
ensure no damage has occurred during tran-
sportation. Any damaged product must be
replaced. No attempt at repairs shall be
made at the job site.
(c) The common temperature changes in a gas
venting application will cause the system to
expand and contract accordingly, proper
care must be taken to allow for this move-
ment through walls, ceilings, and roof pene-
trations. The venting system must be sup-
ported in accordance with these instruc-
tions.
(d) Only approved System 636 PVC or CPVC pri-
mer and cement shall be used to assemble
System 636 PVC or CPVC venting systems
respectively.
* All IPEX System 636 cements contain an
optical brightener to aid in identification
during warranty claims.
Note: Follow IPEX solvent cementing proce-
dures as shown in this manual, and check for
proper joint construction when joining pipe to
fittings.
System 636 Pipe, Fittings and Cements are ce
tified as a system and must be installed assu-
ch. Different manufacturers have different
mat rials, joining systems and adhesives. Do
NOT mix pipe, fittings, solvents, or joining
methods from different BH Vent manufactu-
rers, this can result in unsafe conditions.
(e) Venting should be as direct as possible with a
minimum number of fittings. The maximum
vertical rise or horizontal run of vent pipe in
a single vent installation shall not exceed the
requirements outlined in the appliance
manufacturer's installation instructions. The
total number of vent fittings in a single vent
installation shal not exceed the require-
ments outlined in the appliance manufactu-
rer'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 regula-
tory authority.
(g) All penetrations of fire rated floors and/or
walls shall be as required by the local building
code and/or the local regulatory authority.
All fire stopping of venting shall be completed
using fire stops that are listed by a recogni-
zed agency. Fire stop installationshall be as
per the fire stop device / system manufac-
turer's installationinstructions.
(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) All framing required in conjunction with wall
and roof terminations shall be in accordance
with the local building code and/or the local
regulatory authority.
(j) WARNING: Insulation shall not interfere
with required clearance spaces.
4. Special System Layout Considerations
(a) Vent piping must be sized according to the
equipment manufacturers' recommenda-
tions. IPEX does not recommend the use of
existing vent piping, flues or chimneys.
When old appliances are replaced, do not
connect System 636 venting to existing vent
materials. Replace the entire existing venting
system with ULC S636 listed venting mate-
rial. If transitions between ABS, and PVC or
CPVC must be made at the appliance, only
System 636 PVC/ABS or CPVC/ABS
Transition Cement shall be used. System
636 Primer may only be used on PVC or
CPVC connections. Do not use Primer on
ABS appliance connections.
(b) All horizontal sections of the venting system
must be installed with a slope not less than
0,8 inch (20 mm) per 40 inches (1000 mm)
down towards the appliance in order to pre-
vent collection of condensate. Reference the
appliance manufacturers' instructions regar-
ding installation of necessary condensate
drains.
