Commercial Tankless Venting
COMMON VENTING SOLUTIONS
Up to ten Rheem
®
Commercial Condensing Tankless Water
Heaters can be in-line or back-to-back common vented using
Rheem polypropylene (PPs) header kits and extension pieces.
Common venting saves space and materials
while reducing outer wall penetrations.
Polypropylene is lightweight, assembles quickly, and doesn’t
require glues or solvents to connect. It also meets UL-1738
and ULC-S636 certifications.
Note: If heaters are common vented, you can still manifold
up to 20 units in a bank, however, you must limit the venting
cascade to 10 units.
Easy to Install
• Gasketed, push-fit connection system installs quickly/easily –
No glues, primers or solvents required
• Directional gasket and flow arrows ensure proper vent layout
• Connector ring installs where needed, in seconds ensuring
UL-1738 & ULC-S636 compliance
• Venting parts can be field cut to length to meet any venting
requirement
Tested and Approved by Rheem
• Tested and Listed by Intertek to UL-1738 & ULC-S636 for
temperatures of -4°F to 230°F
• Zero clearance to combustibles in all applications
• All products are UV rated
• LEED friendly
• 100% Recyclable
