Venting & Vent Kits

All indoor tankless gas water heaters must be vented vertically or horizontally to the outdoors using factory approved venting material (No other venting material is permitted). See the Use and Care Manual for important information regarding the venting installation and materials for your tankless water heater.  NOTE: Rheem outdoor tankless water heaters do not require venting materials.

When choosing an indoor location, you should consider the shortest venting distance to the outdoors. Consult your professional installer or contact us for maximum venting distances.

Rheem offers many venting accessories to make your tankless water heater installation easy.

Contact your local Rheem dealer for details and information on our vent kits and solutions for your tankless water heaters.
