USER INSTRUCTIONS
The following instructions are designed for the user of the water heater. The user may not install or adjust the ap-
pliance in any way that requires the removal of the front cover of the unit. To remove the front cover of the unit you

0800 408 5500 and verify the engineer’s name with their database. This is for your own safety.
Responsibilities of the USER
The user must abide by all warnings given in this book. The user must only reference the user section of the book,
and may not carry out any procedure listed in the installer section. This installation manual should be kept with the
appliance for maintenance and user information.
The user must have the unit checked and maintained annually by a gas engineer.
The user must not use the appliance in any way that it was not meant to be used. The user may only use the heater
as detailed in the User portion of this manual.
Interference with a sealed component is not permitted. In case of defect parts only use genuine Rinnai components
for replacement.
practice in the country where the unit is installed.
The user should familiarise themselves with the water heaters gas service valve and the main gas valve to the
premises.
ATTENTION: air surrounding the water heater, venting and vent termination(s) is used for combustion 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.
Therefore Rinnai recommends outdoor models be used for these locations where possible.
The water heater, venting and vent termination(s) 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, Rinnai strongly recommends the following:
Indoor/Internal Water Heaters:
* DO NOT install in areas where contaminated air is present
* Consider before installation where air has the ability to travel within the building
* Where possible, install the water heater in a sealed closet so that it is free of contaminated indoor air
* Chemicals that are corrosive in nature should not be stored or used near the water heater
Outdoor/External Water Heaters and Vent Terminations of Indoor/Internal Water Heaters:
* Install 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 or vent termination.
Damage and repair due to corrosive compounds in the air is not covered by warranty.
The exhaust outlet may change colour over time due to the condensate in the exhaust gases. This discoloration
Benchmark places responsibilities on both manufacturers and installers.
The purpose is to ensure that customers are provided with the
correct equipment for their needs, that it is installed, commissioned
and serviced in accordance with the manufacturer’s instructions by a
competent person(s) and that it meets the requirements of the appropriate
Building Regulations. The Benchmark Checklist can be used to
demonstrate compliance with Building Regulations and should be provided
to the customer for future reference.
Installers are required to carry out installation, commissioning and servicing work in accordance with the
Benchmark Code of Practice which is available from the Heating and Hot water Industry Council who manage and
promote the Scheme. Visit www.centralheating.co.uk for more information.

Check that the appliance is supplied with the correct gas type and pressure
according to the data plate: ensure that the gas in use matches with the gas
indicated on the data plate. If not, there could be incomplete burning of the
gas, resulting in toxic emissions and/or product failure.
Check the main gas valve to make sure it is opened before using the
appliance and check the gas pressure is correct.
Copper or Stainless Steel pipes are recommended for gas and water supply:
rubber hose might get damaged.
It is recommended to install valves on the gas and water pipes to allow an
easier maintenance and to increase safety in case of emergency.
Check the voltage at the power outlet to make sure it is within the appropriate
range before use. Ensure the electrical system is provided with an appropriate
grounding, otherwise the appliance could be severely damaged or operate
improperly.
The extension of the power cord should be avoided (e.g. using an extension
cord or a multiple socket). If the supply cord is damaged, it must be replaced

It is recommended to install a system to collect and drain water under the appliance in the case of water leakage to
prevent material and property damages.
Frost protection: Make sure that the power cord of the appliance is
plugged-in and the electrical power is always available.
The frost protection system activates only when the appliance is electrically
powered and switched ON.
All pipes must be wrapped with insulating materials to prevent heat loss.

All Rinnai water heaters are equipped with a control panel for general appliance
control, hot water temperature selection and diagnostic functions. The control
panel allows you to have full control over the appliance and to adapt it in a
simple and immediate way to the use of hot water according to your needs.
In the indoor models, the control panel is integrated on the front panel of the
appliance and cannot be removed; in the outdoor models, the control panel is available as a remote control to be
connected to the appliance by means of a cable that can be remotely installed in a domestic environment.
The outdoor models can operate without connecting the remote control: the operation of the appliance remains the

are usually installed in environments such as the bathroom, the laundry, etc.
The maximum temperature available for secondary controls is always limited to 50°C from the system: this is to ensure
maximum comfort of use and above all to prevent the risk of burns during use in the environments in which they are
installed.
All control panels are individually programmable, although the appliance only heats the water at one temperature at
a time.

Selectable Temperatures
The appliance is set at the factory to allow the selection of a maximum temperature of 55°C. This limit is generally more
than adequate for most domestic uses, but it is possible to modify it according to your needs. A Rinnai specialized
technician can modify the device electronics by modifying the maximum allowed temperature, bringing it to a higher
value or limiting it further. This change is not permitted to domestic users. Rinnai recommends setting the appliance
to the minimum temperature best suited to the intended use to reduce gas consumption and to increase the life of the
appliance.
The control panel supplied with the appliance is factory blocked: it is possible to increase the temperature up to a
limit of 50°C. Higher temperatures can be obtained only after having unlocked the control panel: correctly performed
the release procedure, it will immediately be possible to increase the delivered temperature and reach the maximum
value set on the appliance. The unlocking (and locking) procedure is described in the section dedicated to installation
instructions, and it is allowed to specialized personnel only.
The temperatures that can be selected using the control panels are as follows:
