the LS Series
Introducing Rinnai’s most innovative offering
Contemporary design
xperience a never-ending supply of fresh hot water – and a sleek, sculpted
water heater design that reflects the innovative technology within. Introducing
E
the Rinnai LS Series, a whole new line of tankless water heaters that afford you
R63LSe
the very best of both form and function. With their attractive silver finish, Rinnai
LS Series units are available in interior and exterior models, giving you virtually
unlimited flexibility to install your unit wherever you choose.
R50LSi
perfect for Any Home
The remarkable combination of design and performance makes the LS Series the perfect
choice. Whether you’re building a spacious new home – complete with luxurious spa bath
and body spray system – or remodeling your older home, Rinnai LS units can be used
individually, in pairs, or in banks of three or more to supply all your hot water needs.
key Features of the LS Series
• Sleek, modern design
• Commercial-grade heat exchanger
for residential and commercial
applications
LS Series interior-mount units can be placed in any room – no need to hide them in
closets or utility rooms – and vent directly to the outside. Exterior units require no
additional venting and can even be installed in a recessed enclosure, then painted or
textured to match the exterior of your home for a clean, inconspicuous appearance.
• Increased hot water output
• EZConnect™ (connects two
units together)*
Improved performance and Longevity
• Integrated condensate collector
for interior models
• Backed by a 12-year heat exchanger
limited warranty, 5 years parts,
1 year labor
Whichever LS unit you choose, you get the
benefit of a newly designed, commercial-grade
heat exchanger for optimum durability. In
fact, the same LS unit can be used for both
residential and commercial applications.
Homeowners get the reliability of commercial-
grade construction and an industry-leading,
12-year limited warranty, and commercial
customers get lower cost and wider availability
of units.
* EZConnect feature is not available for the R63LSe.

Commercial Quality at Your Fingertips
oth commercial and residential customers benefit from the
innovative new heat exchanger design of the LS Series. To achieve
this level of performance, Rinnai engineers used finite element
B
analysis simulation to maximize thermal transfer and minimize thermal
stresses. Rigorous high-temperature reliability testing confirmed the design.
And now Rinnai delivers to you the most reliable, durable tankless water
heater in our history.
Commercial Applications
• Restaurants
This dual-use heat exchanger provides commercial customers a benefit
unique to Rinnai: the ability to access a commercial-grade water heater at
any of our over 2,000 distribution outlets. So, when emergencies occur and
replacement units are needed immediately, you’ll no longer need to wait
for a commercial unit.
• Car Washes, Laundromats
• Schools, Colleges and Universities
• Public Facilities and Event Venues
• Hotels and Motels
• Nursing Homes
• Salons and Spas
Additional Commercial Features and Benefits:
• Industrial Facilities
• Variety of digital controllers allows precise control and monitoring.
• Available wireless controller (MC-502RC-1M/S) provides control
from a central location, even on retrofits.
• Multi-unit options: the EZConnect™* cable (for 2 units) or MSA
control boards (for 3 or more units**) allow units to be used in
combination and in rotation, to avoid wearing out the first unit in a
manifolded series.
• Exterior units can be mounted on outside walls or on rooftops with
no additional protection or venting.
• Rinnai’s concentric venting system means zero clearance, sealed
combustion, and single wall or roof penetration for maximum safety
and installation simplicity.
* EZConnect feature is not available for the R63LSe.
** For each group of five units one MSA-M and three MSA-S control boards are required.

flexibility + control
Accessories
Rinnai’s line of digital controllers allows you to set water temperature
precisely for multiple locations in your home, analyze and troubleshoot
the water heater, and even automatically fill your bath to a pre-set
temperature and volume. An available wireless controller is perfect for
retrofits where pulling a wire through the wall is impractical. (Note: the
MC-91-1-S Standard
Digital Controller
MC-91 controller comes standard with all LS units.)
Flexible Installation
Choosing a mounting location depends on your taste, your home or
building, and your location. Install your Rinnai tankless water heater
inside, outside, in a garage or laundry room or virtually anywhere else.
For interior installation, Rinnai units use a concentric venting system –
a single vent assembly featuring an inner, metal vent for exhaust gases
and an outer PVC or metal tube for bringing combustion air from
outdoors. The result: a direct-vent, sealed-combustion system that offers
optimum safety, performance and ease of installation.
MC-502RC
Wireless Controller
Other benefits include:
• Integrated Condensate
Collector: ensures
condensation doesn’t drain
back into unit, and reduces
cost of venting.
• High-Altitude Operation:
all LS units can be adjusted
for use up to 10,000 ft.
Exterior units can be installed in a recessed enclosure, flush with the
outer wall, then painted or textured to match your home’s panel or
brick siding.
MC-100V-1-S Deluxe

And if you need more than one unit for your larger home, spa or body
spray shower, Rinnai’s EZConnect™ feature allows you to link two units
with a simple cord. For even larger applications, your installer can place
multiple units in parallel.
