Rinnai Australia 4 Owners Guide & Installation Instructions
For detailed instructions on clearances refer to AS/NZS 5601 Fig. 6.2 and for all flueing requirements
refer to separate flue instruction booklet supplied with the flue components.
Horizontal Obstructions
AS/NZS 5601 ‘Gas Installations’ stipulates a minimum
horizontal clearance of 500 mm between a building
structure and obstruction facing the terminal. For Rinnai
external continuous flow water heaters such a building
structure must ‘obstruct’ the full front cover height of the
appliance, or extend vertically above and below the front
cover. There must be no partial obstructions to the front
cover of the appliance or any other parts of the appliance
casing. This will avoid the appliance failing to operate
under windy conditions.
Multiple Installations of External Models
Dimension above does not apply when multiple Rinnai
external water heaters of the same model are installed on
the same vertical face with flue terminals at the same
height. Under these conditions appliances can abut each
other as shown. The total gas consumption of all
appliances applies when determining other clearances.
Safety Devices
The water heating system is supplied with various safety devices including temperature sensors,
overheat sensors and switches. These devices must not be tampered with or removed. The water
heating system must not be operated unless each of these devices is fitted and is in good working
order.
Expansion Control Valve (ECV) - if fitted
Operate the easing lever on the expansion control valve once every six months. It is very important
you raise and lower the lever gently.
It is normal and desirable that this valve allows a small quantity of water to be discharged during the
heating cycle. If it discharges more than a bucket of water during a 24 hour period or discharges
continuously there may be another problem.
If the valve leaks continuously, try easing the valve gear for a few seconds. This may dislodge any
foreign matter and alleviate the problem. If this does not alleviate the problem contact Rinnai.
Operate the easing gear regularly to remove any lime deposits and to verify that it is not blocked.
Servicing and Repair
Our servicing network personnel are fully trained and equipped to give the best on your Rinnai
appliance. If your appliance needs service, ring Rinnai the contact number is on the back of this
booklet.
The expansion control valve must be checked for performance or replaced by an authorised person
at intervals not exceeding 5 years or more frequently in areas where the water is classified as scaling
water (see 'Water Quality').
If the electric conduit, power supply cord or plug to hot water system is damaged, they must be
replaced by an authorised person in order to avoid a hazard. The power supply cord and plug must
be replaced by a genuine replacement part available from Rinnai.
