Spec Sheet  Install Manual

Current SENSEI™ RUR Condensing models will be discontinued and replaced with the New RSC•SERIES Condensing Models with a Built-In Pump and Smart-Circ™ Intelligent Recirculation™..

Enjoy an endless supply of hot water with the SENSEI™ RSC199eP Super High Efficiency Plus condensing tankless water heater from Rinnai. Only the size of a small suitcase, the propane gas RSC199eP model is compact, easy-to-install and perfect for outdoor locations.


With Smart-Circ, installation just got easier. External controllers are no longer required to set-up recirculation for your customers. Smart-Circ “learns” users hot water patterns over a seven-day period, then schedules pump and tankless recirculation patterns accordingly. Users enjoy hot water during regular demand periods, while saving energy and money.

You’re all set! Hot water will be ready for you based on your previous usage schedule. As hot water events are added throughout the week, scheduled recirculation adjusts accordingly.

Rinnai Circ-Logic recirculation technology allows users to set recirculation patterns that coincide with their hot water usage patterns. Hot water is available when needed, without the expense of circulating it during times of inactivity. Two recirculation modes are available:

Dedicated Mode - With a dedicated return line, the integrated pump recirculates water from the tankless water heater through the return line and back to the heater.

Crossover Mode - In applications where a dedicated return line is not available or is difficult to install, Circ-Logic technology allows for the simple installation of a Thermal Bypass Valve (included with purchase) at the fixture farthest away from the water heater

Safety Devices Flame Failure - Flame Rod, Boiling Protection, Combustion Fan RPM Check, Over Current - Glass Fuse, Remaining Flame (OHS) and Automatic Frost Protection

Tankless Water Heater, Thermal Bypass Valve, Pressure Relief Valve and Adapter, Isolation Valve Kit, Integrated Controller
