| All indoor tankless gas water
heaters must be vented vertically or horizontally to the outdoors using
Category III stainless steel venting material (No other venting material is
permitted). RTG-42PV indoor models require 3" stainless steel venting.
RTG-74PV and GT-199PV indoor models require 4" stainless steel venting.
Venting details, including clearances and diagrams, can be found in the "Use
& Care Manual" of Rheem indoor tankless water heaters. 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.

and expertise to make your tankless water heater installation easy -
