2.8. 1 Installation Methods for IPEX System 636 Type BH PVC or CPVC Gas Venting Systems (for Canada Only)
ENG
FR
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 requi-
rements of section 4 of ULC Standard
S636.
1. Application
IPEX System 636 PVC or CPVC Gas Venting
Systems are intended for negative or positi-
ve pressure venting of gas fired appliances
producing exhaust gases having temperatu-
res limited to the range specified in 1(a) and
1(b).
(a) System 636 CPVC venting systems are
suitable for temperatures up to and inclu-
ding 90°C (194°F); ULC S636 Class II.
(b) System 636 PVC venting systems are
suitable for temperatures up to and inclu-
ding 65°C (149°F); ULC S636 Class II.
2. Limiting to Use and Application
(a) Improper installation of System 636
PVC/CPVC systems may result in per-
sonal injury or death.
Only qualified personnel should attempt
the installation of gas burning equip-
ment, following the gas appliance manu-
factures' directions.
(b) All System 636 gas venting pipe and fit-
ting must be carefully inspected before
use to ensure no damage has occurred
during transportation.
Any damaged product must be repla-
ced.
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 accor-
dingly, proper care must be taken to
12
allow for this movement through walls,
ceilings, and roof penetrations.
The venting system must be supported
in accordance with these instructions.
(d) Only approved System 636 PVC or
CPVC primer 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 identifi-
cation 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 certified as a system and must be
installed as such.
Different manufacturers have different
materials, joining systems and adhesives.
Do NOT mix pipe, fittings, solvents, or joi-
ning methods from different BH Vent
manufacturers, 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 installa-
tion shall not exceed the requirements
outlined in the appliance manufacturer's
installation instructions.
The total number of vent fittings in a sin-
gle 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 accor-
dance with the local building code
and/or the local regulatory 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 com-
pleted using fire stops that are listed by
a recognized agency.
Fire stop installation shall be as per the
fire stop device / system manufactu-
rer's installation instructions.
(h) Roof penetrations should be sealed with
a plumbing roof boot or equivalent fla-
shing 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' recom-
mendations.
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 exi-
sting vent materials.
Replace the entire existing venting
system with ULC S636 listed venting
material. If transitions between ABS,
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
