Environment
Air surrounding the water heater is used for
combuson and must be free of any compounds that
cause corrosion of internal components. These
include corrosive compounds that are found in
aerosol sprays, detergents, bleaches, cleaning
solvents, oil based paints/ varnishes, and refrigerants.
The air in beauty shops, dry cleaning stores, photo
processing labs, and storage areas for pool supplies
oen contains these compounds. Therefore it is
recommended that outdoor models be used for these
locaons where possible.
The water heater should not be installed in any areas
where the air may contain these corrosive
compounds. If it is necessary for a water heater to be
located in areas which may contain corrosive
compounds, the following instrucons are strongly
recommended.
IMPORTANT CONSIDERATIONS:
Install the water heater as far away as possible
from exhaust vent hoods.
Install as far away as possible from air inlet
vents. Corrosive fumes may be released through
these vents when air is not being brought in
through them.
Chemicals that are corrosive in nature should not
be stored or used near the water heater.
Damage and repair due to corrosive compounds in
the air is not covered by warranty.

In addion, the solenoid valves should be connected
electrically to a surge protector with terminals. This
allows the solenoid valves to operate if the water
heater is disabled due to a diagnosc code.
The freeze protecon features will not prevent the
external piping from freezing. It is recommended that
hot and cold water pipes are insulated. Pipe cover
enclosures may be packed with insulaon for added
freeze protecon.
In the event of a power failure at temperatures below
freezing the water heater should be drained of all
water to prevent freezing damage. In addion, drain
the condensate trap and drain line.
Checklist to Determine Installaon
Locaon
The water heater is not exposed to corrosive
compounds in the air.
The water heater locaon complies with the
clearances.
The planned exhaust outlet/air intake locaon
meets the clearances.
The water supply does not contain chemicals or
exceed total hardness that will damage the heat
exchanger.
A 120 VAC, 60 Hz source is available.
The installaon must conform with local codes or,
in the absence of local codes, with the Naonal
Fuel Gas Code, ANSI Z223.1/NFPA 54, or the
Natural Gas and Propane Installaon Code, CSA
B149.1. If installed in a manufactured home, the
installaon must conform with the Manufactured
Home Construcon and Safety Standard, Title 24
CFR, Part 3280 and/or CAN/SCA Z240 MH Series,
Mobile Homes.
Leave the enre manual taped to the
temperature controller (if installed), or give the
enre manual directly to the consumer.
Mount to Wall
1. Idenfy the installaon locaon and conrm that
the installaon will meet all required clearances.
2. Securely aach the water heater to the wall using
any of the holes in the wall installaon brackets
which are at the top and boom of the water
heater. Ensure that the aachment strength is
sucient to support the weight. Refer to the
weight of the water heater in the Specicaons
secon.
Use a leveling tool to ensure that the water
heater is level. Proper operaon requires that
the water heater be level.
NOTE: The water heater should be installed in an
upright posion. Do not install upside down or on its
side.
Make sure that in case of freezing weather that the
water heater and its water lines are protected to
prevent freezing. Damage due to freezing is not cov-
ered by the warranty.
Loss of freeze protecon may result in water damage
from a burst heat exchanger or water lines.
With electrical power supplied, the water heater will
not freeze when the outside air temperature is as
cold as –4°F (-20°C) for outdoor models, when pro-
tected from direct wind exposure. Because of the
wind-chilleect, any wind or circulaon of the air
on the unit will reduce its ability to freeze protect.
The unit may be drained manually. However, it is
highly recommended that:
drain down solenoid valves are installed that will
automacally drain the unit if power is lost.
These are available in a kit, 104000059.
Freeze Protecon
V53De Manual 9
Installaon of Plumbing
A manual water control valve must be placed in the
water inlet connecon to the water heater before it is
connected to the water line. Unions may be used on
both the hot and cold water lines for future servicing
and disconnecon of the unit.
DO NOT
Do not introduce toxic chemicals such as those
used for boiler water treatment to the potable
water used for space heang.
MUST DO
The piping (including soldering materials) and
components connected to this appliance must be
approved for use in potable water systems.
Purge the water line to remove all debris and air.
Debris will damage the water heater.
If the appliance will be used as a potable water
source, it must not be connected to a system that
was previously used with a non-potable water
heang appliance.
Ensure that the water lter on the water heater is
clean and installed.
Piping Requirements
Pressure Relief Valve Requirements
Install the pressure relief valve according to local
plumbing codes and these instrucons.
An approved pressure relief valve is required by the
American Naonal Standard (ANSI Z21.10.3) for all
water heang systems, and shall be accessible for
servicing.
DO NOT
Do not plug the relief valve and do not install any
reducing ngs or other restricons in the relief
line. The relief line should allow for complete
drainage of the valve and the line.
Do not place any other type valve or shut o
device between the relief valve and the water
heater.
MUST DO
The relief valve must comply with the standard for
Relief Valves and Automac Gas Shuto Devices for
Hot Water Supply Systems ANSI Z21.22 and /or the
standard Temperature, Pressure, Temperature and
Pressure Relief Valves and Vacuum Relief Valves,
CAN1-4.4.
The relief valve must be rated up to 150 psi and to
at least the maximum BTU/hr of the appliance.
The discharge from the pressure relief valve should
be piped to the ground or into a drain system to
prevent exposure or possible burn hazards to
humans or other plant or animal life. Follow local
codes. Water discharged from the relief valve
could cause severe burns instantly, scalds, or
death.
The pressure relief valve must be manually
operated once a year to check for correct
operaon.
The relief valve should be added to the hot water
outlet line and near the hot water outlet according
to the manufacturers instrucons. DO NOT place
any other type valve or shut o device between
the relief valve and the water heater.
INFORMATION
If a relief valve discharges periodically, this may be
due to thermal expansion in a closed water supply
system. Contact the water supplier or local
plumbing inspector on how to correct this
situaon. Do not plug the relief valve.
The American Naonal Standard (ANSI Z21.10.3)
does not require a combinaon temperature and
pressure relief valve for this appliance. However,
local codes may require a combinaon
temperature and pressure relief valve.
Isolaon Valves
Rinnai strongly recommends the installaon of
isolaon valves on the cold and hot water lines
because they provide the ability to isolate the water
heater from the structures plumbing and allow quick
access to ush the heat exchanger. Flushing the heat
exchanger regularly is required as part of the proper
maintenance for this water heater.
Remove the Front Panel
Slide the plasc trim pieces on each side of the
water heater to expose the screws.
Remove the 4 screws and pull o the front panel.

Connect Water Heater to Water Supply
Water connecons to the tankless water heater
should follow all state and local plumbing codes.
If this is a standard installaon, refer to the Piping
Diagram for Basic Installaon.
1. Plumb the cold water supply to the tankless water
heater on the 3/4” MNPT connecon at the
boom of the unit marked COLD.
2. Plumb the building hot water supply to the 3/4”
MSPT connecon marked HOT.
If a pipe cover will be installed, make sure water lines
to the water heater t.
Checklist for Plumbing
Purge the water line of all debris and air by
closing the hot isolaon valve and opening the
cold isolaon valve and its drain. Debris will
damage the water heater. Use a bucket or hose
if necessary.
Ensure that hot and cold water lines are not
crossed to the unit and are leak free.
Ensure that a pressure relief valve is installed with
a rang that exceeds the BTU input of the water
heater model. Refer to the rang plate on the
side of the water heater for BTU input.
Clean the inlet water lter by closing the cold and
hot water inlet isolaon (shut-o) valves. Put a
bucket under the lter at the boom of the water
heater to catch any water that is contained inside
the unit. Unscrew the water lter. Rinse the
lter to remove any debris. Install the lter and
open the isolaon valves.
Check for proper water pressure to the water
heater. Minimum water pressure is 20 psi. Rinnai
recommends 60-80 psi for maximum
performance.
Installaon of Gas Supply
MUST DO
A manual gas control valve must be placed in the
gas supply line to the water heater. A union can be
used on the connecon above the shut o valve
for the future servicing or disconnecon of the
unit.
Check the type of gas and the gas inlet pressure
before connecng the water heater. If the water
heater is not of the gas type that the building is
supplied with, DO NOT connect the water heater.
Contact the dealer for the proper unit to match the
gas type.
Check the gas supply pressure immediately
upstream at a locaon provided by the gas
company. Supplied gas pressure must be within
the limits shown in the Specicaons secon with
all gas appliances operang.
Before placing the appliance in operaon all joints
including the heater must be checked for gas
ghtness by means of leak detector soluon, soap
and water, or an equivalent nonammable
soluon, as applicable. (Since some leak test
soluons, including soap and water, may cause
corrosion or stress cracking, the piping shall be
rinsed with water aer tesng, unless it has been
determined that the leak test soluon is non-
corrosive.)
Use approved connectors to connect the unit to
the gas line. Purge the gas line of any debris
before connecon to the water heater.
General Instrucons
WARNING / AVERTISSEMENT
1. If you are not knowledgeable or qualied to
install gas lines or connecons, then contact a
licensed professional to install the gas supply.
2. Turn o 120v power supply.
3. Turn o the gas.
4. Gas is ammable. Do not smoke or provide other
ignion sources while working with gas.
5. Do not turn on the water heater or gas unl all
fumes are gone.
12 V53De Manual
Size the gas pipe
The gas supply must be capable of handling the enre
gas load at the locaon. Gas line sizing is based on
gas type, the pressure drop in the system, the gas
pressure supplied, and gas line type. For gas pipe
sizing in the United States, refer to the Naonal Fuel
Gas Code, NFPA 54. The below informaon is
provided as an example. The appropriate table from
the applicable code must be used.
1. For some tables, you will need to determine the
cubic feet per hour of gas required by dividing the
gas input by the heang value of the gas
(available from the local gas company). The gas
input needs to include all gas products at the
locaon and the maximum BTU usage at full load
when all gas products are in use.
2. Use the table for your gas type and pipe type to
nd the pipe size required. The pipe size must be
able to provide the required cubic feet per hour
of gas or the required BTU/hour.
Example:
The heang value of natural gas for your locaon is
1000 BTU/FT
3
. The gas input of the V53De is 120,000
BTU/HR. Addional appliances at the locaon require
65,000 BTU/hr. Therefore the cubic feet per hour =
(120,000 + 65,000) / 1000 = 185 FT
3
/HR. If the pipe
length is 20 feet then the 3/4 inch pipe size is capable
of supplying 188 FT
3
/HR of natural gas.
Gas Input of all gas products (BTU / HR)
Heang Value of Gas (BTU / FT
3
)
Cubic Feet
per Hour =
(CFH)
Any compound used on the threaded joint of the
gas piping shall be a type which resists the acon
of liqueed petroleum gas (propane / LPG).
The gas supply line shall be gas ght, sized, and so
installed as to provide a supply of gas sucient to
meet the maximum demand of the heater and all
other gas consuming appliances at the locaon
without loss of pressure.
INFORMATION
Refer to an approved pipe sizing chart if in doubt
about the size of the gas line.
