CHAPTER 1 - PRE-INSTALLATION REQUIREMENTS
1.2. Vent/Combustion Air Piping and Materials
The installation must conform to the require-
ments of the authority having jurisdiction or,
in the absence of such requirements, to the
National Fuel Gas Code, ANSI Z223.1/ NFPA 54,
and/or Natural Gas and Propane Installation
Code, CAN/CSA B149.1.
The Prestige is certied per ANSI Z21.13 as a Category IV
(indoor air) or Direct Vent (sealed combustion) appliance.
A Category IV appliance utilizes uncontaminated indoor
or outdoor air (surrounding the appliance) for combus-
tion. A Direct Vent appliance utilizes uncontaminated out-
door air (piped directly to the appliance) for combustion.
To reduce the potential risks associated with
indoor contaminates (listed on page 11), flam-
mable vapors and tight housing construction
(little or no infiltration air), it is recommended
to pipe uncontaminated combustion air di-
rectly from the outdoors to the appliance. This
practice also promotes higher system efficien-
cy by reducing heated indoor air from being
exhausted from the building and replaced by
cold infiltration air.
The Prestige requires a Category IV venting system which
is designed for pressurized venting and condensate.
The vent and combustion air materials (piping,
fittings and cement) must meet the listed re-
quirements in this manual. Failure to comply
with these material requirements can result in
substantial property damage, serious injury, or
death.
1.2.1 PVC and CPVC Vent and Combustion Air
Piping and Fittings
• PVC Schedule 40 - ANSI/ASTM D1785
• PVC-DWV - ANSI/ASTM D2665
• CPVC Schedule 40 - ANSI/ASTM F441

WARNING
1.2.2 PVC and CPVC Pipe Cement and Primer
• PVC - ANSI/ASTM D2564
• CPVC - ANSI/ASTM F493
• For installations in Canada, all piping, fit-
tings and cement/primer material must be
certified and listed to ULC-S636. Ipex Inc. is
an approved manufacturer of ULC S636 vent
components.
• Use of cellular core PVC (ASTM F891) cel-
lular core CPVC, or Radel® (polyphenol-
sulfone) in venting systems is prohibited.
Cellular core pipe may be used for combus-
tion air piping.
DO NOT mix a PVC/CPVC vent system & com-
ponents with other vent system materials &
components. Seal all PVC and CPVC pipe and
fittings with the appropriate primer and ce-
ment. Failure to comply with this requirement
can cause the venting system to fail resulting
in substantial property damage, serious injury,
or death.
1.2.3 AL29-4C® Stainless Steel Vent Piping and
Fittings
Approved AL29-4C® Stainless Steel vent manufacturers
and vent systems:
• SelKirk/Heatfab
• Muelink and Grol B.V./Dura Vent
• Z-FLEX U.S. Inc.
Only use approved stainless steel vent adapters and
terminations listed in Table 1 on page 3.
Contact approved AL29-4C® stainless steel
vent manufacturer for a copy of their instal-
lation instructions. Read, understand and fol-
low all of the vent manufacturer’s instructions
before beginning the installation. Contact
vent manufacturer if you require any tech-
nical support. Failure to properly install and
support vent system can cause the venting
system to fail, resulting in substantial proper-
ty damage, serious injury, or death.
