WARRANTY, FEATURES & SPECIFICATIONS

WARRANTY

The benefits to the consumer given by this warranty are in addition to all other rights and remedies of the consumer
under a law in relation to the goods or services to which the warranty relates.

Our goods come with guarantees that cannot be excluded under the Australian Consumer Law. You are entitled to
a replacement or refund for a major failure and for compensation for any other lo ss or damage. You are also entitled
to have the goods repaired or replaced if the goods fail to be of acceptable quality and the failure does not amount
to a major failure.

This heater has a 7 year parts warranty from date of purchase. If the product fails within this 7 year period return it
to the supplier with proof of purchase for repair or replacement.

Supplier warranty claims for Rinnai products or services must be made by contacting Rinnai Australia. Contact
details are on the back of this document.

The following exclusions may cause the warranty to become void and may result in a service charge and costs of
parts (if required):

1. Accidental damage and acts of God.

2. Failure due to abuse or misuse, improper maintenance, failure to maintain or improper storage.

3. Failure due to incorrect or unauthorised installations or outdoors use.

4. Failure or damage caused by alterations, service or repair work carried out by persons other than Rinnai service
persons or service agents.

5. Where it is found that there is no fault with the appliance and the issue is related to the installation or is due to
the failure of electricity supply.

FEATURES

This heater incorporates the following design features.

DIY Installation: This heater is suitable for Do It Yourself installation.
Silent Operation: Electric element operation eliminates fan noise.
Draft Free: Non fan operation also means no drafts.
Low Maintenance: No moving parts makes for virtually maintenance free operation.
Delay Off Timer Function: Equipped with delay off timer, which can be set in 1 hour increments from 1

to 24 hours.

`Tamper Resistant´ Operation: Includes a Lock function desig ned to prevent accidental operation and small

children from altering the heater settings .

Operation: The heater uses electricity as the heating medium. It operates on the ‘natural

convection’ principle where air from the room is drawn into the ‘air inlet’
louvres at the base of the appliance, is heated inside the appliance and
expelled through the ‘air outlet’ louvres at the top of the appliance without the
use of fans. A sophisticated thermostatic system keeps the room close to the
selected temperature.

To remove dust and clean the appliance:

1. Unplug the electric plug of the heater from the socket outlet before commencing cleaning.

2. Allow to cool down.

3. Use a vacuum cleaner to remove any dust and fluff from the inlet and outlet louvres.

4. All parts of the heater can be cleaned using a soft, damp cloth with some mild detergent (such as dishwashing
liquid) if required.

5. Ensure the heater is dry before reconnecting to the electricity supply.

SERVICE AND REPAIR

If the electric power cord or plug are damaged, they must be replaced by Rinnai or a Rinnai appointed service agent.
There are no user serviceable parts inside the appliance. All service and rep air work must be carried out by persons

competent and permitted by law to do so.
If the heater requires service or repair contact your supplier or Rinnai Australia.
