Rinnai gas water heater models R50LSi, R63LSe and V53e are
residential and commercial tankless units designed to deliver endless
and almost instant hot water for up to three bathroom or plumbing
outlets, using natural gas or propane (LP) gas.

R50LSi
and R63LSe Review

Rinnai gas water heaters
R50LSi
and R63LSe
are working on demand and fast, right after you open the hot water
tap. They deliver up to 5 and 6.3 gallons
per minute, which is enough hot water for up to three applications.

If there is a demand for even more hot water, EZConnect feature
is available for R50LSi models, and with a simple cord you can
combine two units and gain even more power and capacity.

To manifold two to five R63LSe
Rinnai
gas heaters use Rinnai pressure activation
valves, PVA, to
provide a stable water temperature and make units work more
efficiently.

MC-91-1 digital controller with error code indicator is the standard
equipment for almost all Rinnai tankless hot water heaters, giving you
freedom to precisely control and adjust the
temperature and troubleshoot by using the error codes
display.

Rinnai R50LSi

Rinnai gas water heater R50LSi with the energy factor of 0.82 and maximum gas rate of 150,000
BTU is the Energy Star and high efficient unit,
and therefore
qualified for government tax credits and rebates.

R50LSi
models are also direct vent with forced combustion where proper venting
has to be provided. With good venting they can be installed almost
anywhere in your house. The best is close to the actual point of use
application, as the hot water supply line is shorter, making the wait
time
shorter and heat loss reduced.

Rinnai R63LSe

Rinnai gas water heater R63LSe has the energy
factor of 0.81 for both gas types and maximum gas rate of 150,000 BTU
(R63LSe EF
value is the smallest of all Rinnai tankless water heaters).

R63LSe models,
when
used in commercial applications can heat the water up to 160 F but it
requires an MCC-91 commercial controller, which you have to buy
separately.

When you buy Rinnai R63LSe
you don't have to spend more money on Rinnai vent kits,
as they do not require venting, they are outdoor units and can
be installed easily on the exterior wall.

These exterior water heaters are ideal if you are remodeling
your
home, and want to get rid of the old tank type water heater. You can
use the extra valuable space that your tank occupied for
something else.

V53e
Review

Rinnai
gas water heater V53e model is another
exterior unit that can be installed on the outside
wall and requires no additional venting or protection, so you
don't have to worry
about possible gas leak, venting system installation, flue gases, water
leaking or freezing.

Even hanging outside they are still able to provide sufficient
hot water for up to two bathrooms or shower and kitchen sink at the
same time, with a consistent and safe temperature for
residential
applications.

Max gas input for propane and natural gas is 120,000 BTU;
energy
factor is 0.82 and water delivery of 5.3 gallons per minute. The
optimum temperature is factory pre-set on 120 F, great feature
for kids in providing scalding protection and maximum
energy savings for you, but it can be changed up to
140 F.

Rinnai gas water heater V53e model still provides the decent
warranty on heat exchangers, 10 years. And often standard equipment,
MC-91-1
remote control is not included, it is optional feature; error codes are
displayed on front panel LED indicator.

Safety
features

• Boiling and overheat protection - if the hot water
  exceeds the pre-determined temperature, the unit will automatically
  shut down.

• Combustion fan RPM check

• Flame rod in a case of flame failure shuts
  the heater automatically.

• Remaining flame (OHS)

• Thermal fuse will break and shuts-off the appliance
  if the overheat system does not prevent the temperature from rising.

• Over current protection with glass fuse - when the
  fuse blows all indicator lamps will be off.

• Automatic freeze protection (warranty does not cover
  water heater and
  parts damage, due to freezing).

• An auto
  drain down solenoid valves for freeze protection can be used as back-up
  when normal freeze protection is disabled. This is not
  standard equipment, and has to be purchased separately.

• Min and max pressure system protects unit
  from lack of water in the and high pressure in plumbing.
