Venting

Depending on placement within the home, internal Rinnai Tankless Water Heaters can vent vertically through the roof or horizontally through an exterior wall. Each option features concentric venting that requires only a single wall penetration for both the intake and exhaust and has zero clearance to combustibles.

External Rinnai Tankless Water Heaters do not require additional venting.

Gas Line Sizing

Rinnai Tankless Water Heaters typically require a ¾” gas line to provide a sufficient gas supply to the unit’s burner. However, if there is sufficient pressure and the gas line is short enough, there are some cases where a ½” gas line can be used, which is the most common size used in the United States and Canada. This can make switching from a tank-style water heater to a tankless water heater faster, easier and less expensive.

As with all tankless water heater applications, installers should check and abide by local gas-pipe size and licensing rules and codes.

Proper Installation

Rinnai recommends that tankless water heater installation should be performed by a licensed contractor who is trained to handle the plumbing, gas, electrical and venting aspects of a tankless water heater and is aware of all local and national codes. Having a non-licensed professional perform the installation can cause operational and performance issues.
