Description of Operation
The Rinnai water heater is one of the most advanced
water heaters available. It provides a continuous
supply of hot water at a preset temperature.
Ignition is electronic. There is no pilot light consuming
gas while the water heater is not being used. The gas
burner lights automatically when the hot water tap is
opened and goes out when the tap is closed.
This appliance is a direct vent appliance where air is
brought in from the outside and combustion gases are
exhausted to the outside.
Installation of the temperature controller is highly
recommended. The temperature controller can set the
temperature within a specific range and can provide
error codes to diagnose any problems.
While electricity, water, and gas supplies are
connected, the Rinnai water heater produces hot water
whenever a hot water tap is open.
The temperature of the outgoing hot water is constantly
monitored. The Rinnai water heater may adjust the
water flow in order to maintain the temperature setting.
The water flow may vary from summer to winter due to
the difference in ground water temperature.

** MCC-91 Temperature Controller
These settings require the MCC-91 controller. When the MCC-91
controller is connected, these higher temperatures are available on all
controller models in the system. Use of an MCC-91 controller in a
residential dwelling will reduce the warranty coverage to that of a
commercial warranty application.
The MCC-91 controller is intended for commercial and hydronic
applications only. If an MCC-91 controller is used in a residential
dwelling for a hydronics application, a mixing valve must also be
installed to limit the potable hot water temperature to a safe
temperature. Water temperatures over 125º F (51º C) can cause severe
burns or scalding. Refer to the Danger Alert on water temperatures.
Rinnai shall not, in any event, be liable for damages resulting from such
misuse or misapplication.
A temperature lower than 98º F (37º C) can be
obtained at the tap by mixing with cold water.
Suggested temperatures are
•Kitchen 120 ºF (49º C)
•Shower 98º - 110º F (37º - 43º C)

Trouble Shooting for Common Issues
I don’t have any hot water when I open the tap.
White smoke comes out of the exhaust.
Make sure there is gas, water, and electricity to the
Rinnai water heater (power is turned on and the gas is
turned on).
During colder weather when the exhaust temperature
is much hotter than the outside air, the exhaust fumes
condense producing water vapor.
When I open a hot tap, I do not immediately get hot
water.
When I was using the hot water, the water got cold.
If you adjusted the flow from the tap to lessen it, you
may have gone below the minimum flow required. The
Rinnai water heater requires a minimum flow rate to
operate. (See the specification page for the flow rate
of your model.)
Hot water must travel through your plumbing from the
Rinnai water heater to the faucet. The time period for
hot water to reach your fixture is determined by the
amount of water in the plumbing system between the
water heater and the fixture, water pressure, and the
flow rate of the fixture.
If you are experiencing issues with higher temperature
settings, then Rinnai recommends reducing the
temperature setting. Selecting a temperature closer to
that which is actually used at the faucet will increase
the amount of hot water being delivered to the faucet,
due to less cold water mixing at the fixture.
After I turn off the hot water tap, the fan on the
Rinnai water heater continues to run.
The fan is designed to continue running for a short time
after the flow of water stops. This is to ensure constant
water temperatures during rapid starting and stopping,
as well as exhausting any residual gas flue products
from the unit.

Gas Piping
Pipe Sizing Procedure - Example
The gas supply must be capable of handling the entire gas load at the location. 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 National Fuel Gas Code, NFPA 54. For Canadian gas pipe sizing, refer to the Natural
Gas and Propane Installation Code CAN/CSA B149.1. The below information 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 heating value of the gas (available from the local gas company). The gas input needs to include all gas
products at the location and the maximum BTU usage at full load when all gas products are in use.
Gas Input of all gas products (BTU / HR)
Cubic Feet per Hour (CFH) =
Heating Value of Gas (BTU / FT 3 )
2.Use the table for your gas type and pipe type to find 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 gas input of the RL94e is 199,000 BTU/HR using propane. Additional appliances at the location
require 75,000 BTU/hr. Therefore the maximum BTU usage will be 274,000 BTU/hr.
If using propane gas with Schedule 40 metallic pipe, 100 ft in length, then the 1 inch pipe size will be
capable of supplying 372,000 BTU/hr of propane gas..

Water Piping
Isolation Valves and Pressure Relief Valve (RL75e and RL94e)
The isolation valves provide the ability to isolate the
water heater from the structure’s plumbing and allow
quick access to flush the heat exchanger. Check with
local codes to determine if a pressure and temperature
relief valve is required. The included valves meet
American National Standard (ANSI Z21.10.3) /
Canadian Standard (CSA 4.3) and are ANSI/NSF 65
approved for potable water.

1. Wrap the ends of the threaded water inlet & outlet
on the tankless water heater,as well as the
threaded end of the approved pressure relief valve
with a minimum of 5 wraps of Teflon® tape.
2. Screw the pressure relief valve into the 3/4”
threads opposite the wing handle on the HOT
water service valve. (RED drain handle) (see
Pressure Relief Valve Section for proper
installation requirements)
Pressure Relief Valve Installation Instructions:
The PRV must be connected by the threaded
connection opposite the wing handle on the hot water
valve (designated by the RED drain handle) or the
threaded connection on the side of the relocation
fitting above the hot water valve. Installation must
maintain a ¾” port size with no shut off valve or line
restriction in-between the appliance and the PRV. The
discharge line from the PRV should pitch downward
and terminate 6” above drains where discharge will be
clearly visible. The discharge end of the line shall be
plain (unthreaded) and a minimum of ¾” in diameter.
The discharge line material must be suitable for water
at least 180º Fahrenheit and can be no more than 30
feet in length and contain no more than 4 elbows or
bends. No valve of any type may be installed in the
discharge line of the pressure relief valve.
3. Loosen the 3/4” union nut on the HOT water valve
and connect to the HOT water outlet on the
tankless water heater. If nut is removed, ensure
that you realign the tailpiece accurately to the
valve and that the black washer is positioned such
that the raised metal edge of the valve is inside
the washer.
4. Align the direction of the HOT water drain to the
desired position.
5. Tighten the union assembly to the HOT water
valve using approximately 15 foot lbs of torque.

7. Connect the INLET on the COLD water valve to
the MAIN SOURCE of the water supply.
For proper care of this approved pressure relief valve,
it is recommended that the valve is manually operated
once a year. In doing so, it will be necessary to
take precautions with regard to the discharge of
potentially scalding hot water under pressure. Ensure
discharge has a place to flow. Contact with your body
or other property may cause damage or harm.
Please note that only the PRV in this package is
certified by CSA International as an approved item.
8. Connect the OUTLET on the HOT water valve to
the HOT WATER plumbing system.

General Instructions
• A manual water control valve must be placed in the
water inlet connection to the Rinnai 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 disconnection of the unit.
• Toxic chemicals such as those used for boiler water
treatment are not to be introduced to the potable
water used for space heating.
• 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 nonpotable water
heating appliance.
• The piping (including soldering materials) and
components connected to this appliance must be
approved for use in potable water systems.
• Ensure that the water filter on the Rinnai water
• Purge the water line to remove all debris and air.
heater is clean and installed.
Debris will damage the Rinnai water heater.
Pressure Relief Valve
• An approved pressure relief valve is required by the
American National Standard (ANSI Z21.10.3) /
Canadian Standard (CSA 4.3) for all water heating
systems, and shall be accessible for servicing.
• The relief valve should be added to the hot water
outlet line and near the hot water outlet according to
the manufacturer’s instructions. DO NOT place any
other type valve or shut off device between the relief
valve and the water heater.
• The relief valve must comply with the standard for
Relief Valves and Automatic Gas Shutoff 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.
• Do not plug the relief valve and do not install any
reducing fittings or other restrictions in the relief line.
The relief line should allow for complete drainage of
the valve and the line.
• 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 situation.
Do not plug the relief valve.
• 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.
• Neither Rinnai nor the American National Standard
(ANSI Z21.10.3) / Canadian Standard (CSA 4.3)
requires a combination temperature and pressure
relief valve for this appliance. However, local codes
may require a combination temperature and
pressure relief valve.
• The pressure relief valve must be manually
operated once a year to check for correct operation.
Freeze Protection
The freeze protection features include electrical
heating elements. Freeze protection may be disabled
if electricity is not supplied, or if there is an error
preventing the water heater from functioning. Loss of
freeze protection may result in water damage from a
burst heat exchanger or water lines.
The condensate trap drain plug and water drain plug
are not affected by the auto drain down solenoid valves
and will have to be manually opened.
The freeze protection features will not prevent the
external piping from freezing. Rinnai recommends
heat tracing and insulating hot and cold water pipes
connecting units. Pipe cover enclosures may be
packed with insulation for added freeze protection.
The installation of auto drain down solenoid valves is
optional. However, Rinnai strongly recommends that
these valves be installed to prevent damage from
freezing in case the normal freeze protection should
become disabled. Any product damage due to
freezing will not be covered by the warranty.
With electrical power supplied, Rinnai water heaters
will not freeze when the outside air temperature is as
cold as –22ºF (-30ºC) for indoor models or is as cold
as –4ºF (-20ºC) for outdoor models, when protected
from direct wind exposure. Because of the “wind-chill”
effect, any wind or circulation of the air on the unit will
reduce its ability to freeze protect.
In addition, 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 an error code.
The solenoid valves and surge protector with terminals
are available for purchase at Rinnai.

Space Heating
If the water heater is to be used for both water (potable) heating and space heating then the following apply.
•
•
•
The piping and components connected to the water heater shall be suitable for use with potable water.
Toxic chemicals, such as used for boiler treatment, shall not be introduced into the potable water.
The water heater shall not be connected to any heating system or components previously used with a
nonpotable water heating appliance.
•
When the system requires water for space heating at temperatures higher than required for other uses, a
means such as a mixing valve shall be installed to temper the water for other uses in order to reduce the
scald hazard potential.
Space heating applications are considered commercial applications for warranty purposes.
Temperature Setting
When using this appliance to provide domestic hot water it is recommended that the domestic hot water
temperature be reduced to acceptable temperatures in accordance with local codes. In the absence of local
codes it is recommended that the domestic hot water temperature be set to 140º F (60º C) or lower in accordance
with UPC 501.6 by using mixing valves or the temperature controller for the water heater.
Pumps
Only use pumps of brass or stainless steel construction. Do not use pumps of iron construction as they will
oxidize and clog the inlet filter on the appliance.
Pumps circulating water through the water heater must be sized to overcome the pressure loss through the water
heater, the heating system, and any additional plumbing pressure losses. The pressure drop curve based on the
water heater model is provided in this manual.
Replacement
When replacing an existing space heating application’s water heating source (boiler, tank water heater, tankless
water heater, etc.) with Rinnai water heaters, ensure that the water heaters are sized to adequately provide the
necessary BTU input for the desired space heating application. Rinnai water heaters are designed to maintain a
constant outlet temperature and will supply only the necessary amount of BTU’s to maintain that temperature.
Depending on the application the maximum BTU rating of the unit may not be achieved. Contact Rinnai’s
Applications Engineering Department for assistance at (800) 621-9419 ext. 4490.
Iron Components
Do not use Rinnai water heaters directly for space heating applications involving iron radiators or applications with
any iron components. Iron components may oxidize creating rust that will clog the inlet filter of the Rinnai water
heater.

Limited Warranty
What is covered?
This Warranty covers any defects in materials or workmanship when the product is installed and operated according to Rinnai
written installation instructions, subject to the terms within this Limited Warranty document. This Warranty applies only to
products that are installed correctly. Improper installation may void this Warranty. Rinnai strongly suggests that you use a
state qualified or licensed installer who has attended a Rinnai product knowledge class before installing this water heater. This
Warranty extends to the original purchaser and subsequent owners, but only while the product remains at the site of the
original installation. This Warranty only extends through the first installation of the product and terminates if the product is
moved or reinstalled at a new location.

* Note: Period of coverage is reduced to 3 years from date of purchase when used as a circulating water heater within a hot
water circulation loop, where the water heater is in series with a circulation system and all circulating water flows
through the water heater, and where an on-demand recirculation system is not incorporated.
On-demand recirculation is defined as a hot water recirculating loop or system that utilizes existing hot and cold lines
or a dedicated return line, and only activates when hot water is used. It can be activated by a push button, motion
sensor, or voice activation but not by a temperature sensor. A timer added to a standard recirculating pump is not
considered as on-demand.
There is no warranty coverage on product installed in a closed loop application, commonly associated with space
heating only applications.
Use of an MCC-91 controller in a residential dwelling will reduce the warranty coverage to that of a commercial
warranty application (except when an MCC-91 is used with a Rinnai Hydronic Air Handler).
The integrated controller on indoor models has a 1 year warranty on parts.
† Note: Period of coverage is reduced to 3 years from date of purchase if the Rinnai water heater temperature setting
exceeds 160º F (71º C).

** MCC-91 Contrôleur de Température Ces cadres exigent le MCC-91 contrôleur. Quand
le MCC-91 contrôleur est connecté, ces plus hautes températures sont disponibles sur
tous modèles de contrôleur dans le système. L'usage d'un MCC-91 contrôleur dans une
demeure résidentielle réduira la couverture de garantie à cela d'une application de
garantie commerciale.
Le MCC-91 contrôleur est l'intention eu pour les applications de publicité et hydronic
seulement. Si un MCC-91 contrôleur est utilisé dans une demeure résidentielle pour
une application de hydronics, une soupape mélangeant doit être aussi installée pour
limiter la température d'eau chaude potable à une température sûre. Arroser des
températures plus de 125º F (51º le C) peut causer des brûlures ou scalding sévère.
Se référer à l'Alerte de Danger sur les températures d'eau. Rinnai ne fait pas, en tout
cas, être responsable des dommages qui résultent de tel usage impropre ou tel
mauvais usage.
Une température inférieure à 98º F (37 ºC) peut s'obtenir par
ajout d'eau froide avec un robinet mitigeur.
Les températures suggérées sont de :

102º - 110º F (39º - 43º C)
Pour passer l'affichage de température de Celsius à
Fahrenheit ou vice versa, actionnez et maintenez enfoncé le
bouton M/A pendant 5 secondes avec le chauffe-eau en
position d'arrêt.
Ces températures ne sont que des suggestions.
Options de température sans contrôleur à distance
Le réglage de température de consigne par défaut pour cet appareil sans un contrôleur à distance est de 120º F (49 ºC). On
peut, si on le souhaite, la passer sur 140º F (60 ºC) en modifiant la position d'un seul micro-commutateur DIP.
À la banque SW1 de 8 interrupteurs à positions multiples, le micro-commutateur 5 donne un réglage à 120°F (49 ºC) s'il est
sur OFF (valeur automatique) mais à 140°F (60 ºC) s'il est sur ON.
Si un contrôleur de température est installé, alors le contact DIP 5 n'a aucun effet sur des arrangements de température.

Instructions d'utilisation
À LIRE AVANT LA MISE EN SERVICE POUR VOTRE SÉCURITÉ
Si vous ne suivez pas exactement ces instructions, il peut en
résulter un départ d'incendie ou une explosion, causant dégâts
A. Cet appareil ne comporte pas de veilleuse. Il est muni
d’un dispositif d’allumage qui allume automatiquement le
brûleur. Ne tentez pas d’allumer le brûleur
manuellement.
• Si vous ne pouvez rejoindre le fournisseur, appelez le
service des incendies.
C. Ne poussez ou tournez la manette d’admission du gaz
qu’à la main ; ne jamais utiliser d’outil. Si la manette
reste coincée, ne pas tenter de la réparer ; appelez un
technicien qualifié. Le fait de forcer la manette ou de la
réparer peut déclencher une explosion ou un incendie.
B. AVANT DE FAIRE FONCTIONNER, reniflez tout autour
de l’appareil pour déceler une odeur de gaz. Reniflez
près du plancher, car certains gaz sont plus lourds que
l’air et peuvent s’accumuler au niveau du sol.
D. N’utilisez pas cet appareil s’il a été plongé dans l’eau,
même partiellement. Faites inspecter l’appareil par un
technicien qualifié et remplacez toute partie du système
de contrôle et toute commande qui ont été plongés dans
l’eau.
QUE FAIRE SI VOUS SENTEZ UNE ODEUR DE GAZ :
• Ne pas tenter d’allumer d’appareil.
• Ne touchez à aucun interrupteur ; ne pas vous servir
des téléphones se trouvant dans le bâtiment.
• Appelez immédiatement votre fournisseur de gaz
depuis un voisin. Suivez les instructions du
fournisseur.

une odeur de gaz, ARRÊTEZ ! Passez à l’étape B des
instructions de sécurité sur la portion supérieure (à
gauche) de cette étiquette. S’il n’y a pas d’odeur de gaz,
passez à l’étape suivante.
2.Réglez le thermostat sur la consigne la plus basse.
3.Coupez l'alimentation électrique de l'appareil en utilisant
son bouton M/A.
4.L'appareil est équipé d'un dispositif d'allumage qui allume
automatiquement le brûleur. N'essayez pas de l'allumer
manuellement.
7.Ouvrez l'arrivée de gaz en tournant la vanne manuelle de

Informations sur la garantie
L'installateur est responsable de l'installation correcte de votre chauffe-eau.

Garantie limitée
Qu'est-ce qui est couvert ?
Cette garantie couvre tous défauts dus aux matériaux et à la main d'œuvre quand le produit a été installé et utilisé en suivant
les instructions écrites d'installation de Rinnai, dans les termes décrits dans ce document de garantie limitée. Cette garantie
s'applique seulement aux produits qui sont installés correctement. Une installation incorrecte pourrait annuler cette garantie.
Rinnai vous recommande fortement d'employer un installateur qui aura suivi une classe Rinnai pour la connaissance des
produits avant d'installer le chauffe-eau. Cette garantie couvre l'acheteur d'origine uniquement tant que le produit reste sur le
site de son installation initiale. Cette garantie ne joue qu'après la toute première installation du produit et se termine s'il est
déplacé ou réinstallé à un autre emplacement.
Combien de temps dure la couverture ?

* Note : La période de couverture est réduite à 3 ans à partir de la date d'achat quand le chauffe-eau est utilisé comme chauffage
d'eau circulante dans une boucle de circulation d'eau chaude, où il est utilisé en série avec un système de circulation, et que
toute l'eau qui circule passe au travers de lui, et où un système de recirculation à la demande n'est pas incorporé.
Une recirculation à la demande est définie comme une boucle de recirculation d'eau chaude ou un système qui utilise des
conduites d'eau chaude et froide existantes, ou une conduite de retour dédiée, et qui ne s'active que lorsque de l'eau chaude
est utilisée. L'activation peut se faire par bouton poussoir, détecteur de mouvement ou activation vocale, mais pas par un
capteur de température. Une minuterie ajoutée sur une pompe de recirculation standard n'est pas considérée comme
donnant un système à la demande.
L'utilisation d'un contrôleur MCC-91 dans une habitation résidentielle réduira la couverture de garantie au niveau de la
garantie pour une application commerciale
† Note : La période de garantie est réduite à 3 ans à partir de la date d'achat si le réglage de température du chauffe-eau Rinnai
dépasse 160°F (71 °C).

•
•
•
•
•
accident, abus, mauvais usage

•
•
entretien inadéquat (comme sans y être limité accumulation de tartre, dommages dus au gel, blocage de ventilation)

Cette garantie vous donne des droits légaux spécifiques, et vous pouvez également avoir d'autres droits qui peuvent varier
d'un état à l'autre.
