At  Rinnai,  we’ve  sold  more  tankless  water  heaters  worldwide  than  anyone  else.  Our  complete 
commitment to safety, quality and the environment has also made us #1 in the U.S. market.

As the leading manufacturer of gas heating products worldwide, Rinnai continues
innovating  to  ensure  a  greener  environment.  Rinnai’s  superior  heating  and  hot 
water technologies deliver greater efficiency and reliability, so everyone benefits – 
with environmental preservation and energy conservation that results in a better 
planet for us all. 

The Rinnai can be vented vertically or horizontally.

CUSTOM INSTALLATIONS to match the outside appearance of the home 
or to blend in with the interior (shown with optional pipe cover).

 

MOUNT 
installations 
require no 
additional 
venting 
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 controller comes standard with all LS units.)

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.
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.
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.
