All terms of the warranty are effective from the date of installation of the Rinnai Demand Duo

system. Rinnai New Zealand Limited (Rinnai) reserves the right to verify this date.

Domestic vs. Commercial Application

The reason for distinguishing between a domestic and commercial application is because the

expected life of a system is directly related to the hours of use.

A domestic application is dened as an installation that serves a single residential dwelling

which is not used for commercial purposes, such as a hair salon, catering kitchen, motel or

communal care facility.

All other installations are dened as a commercial application.

General Warranty Terms

Rinnai reserves the right to make modications and change specications and its parts without

notice.

For the purposes of the Consumer Guarantees Act 1993, Rinnai only guarantees the availability

of repair facilities and spare parts for the express warranty periods recorded in the Rinnai

Warranty Summary Table.

If the Rinnai Demand Duo system is being acquired for personal, domestic or household

use, this warranty does not limit any consumer rights or guarantees that may apply under

the Consumer Guarantees Act 1993. If the product is being acquired for the purposes of a

business, the provisions of the Consumer Guarantees Act 1993 do not apply and no other

warranties (either express or implied by law) apart from those stated in this warranty apply.

Customer Information - Introduction

This manual has been written to:

Help you understand how your Demand Duo Lite operates

Identify what you need to do to maintain your Demand Duo Lite system

Assist in troubleshooting in the unlikely event a problem occurs

Some facts about your Demand Duo Lite system

•

How it works The thermostat senses the temperature of the water in the tank, and when

it drops below the set point, the primary pump is activated. This ow starts

the Rinnai continuous ow water heater which returns heated water to the

tank.

Safety devices For safe operation the tank component of your system is tted with a:

Temperature Pressure and Relief (TPR) Valve that ensures the water

remains at a safe pressure and temperature

Automatic tank thermostat to maintain water temperature, do not

adjust the thermostat which is set to 65 °C

It is important that you do not tamper with or remove these devices. In the

case of the TPR valve, do not block or seal the valve or drain pipe.

•

Anode The tank is tted with a sacricial anode designed to extend the life of the

tank. It will slowly dissipate protecting the cylinder and should be changed

every 5 years (more frequently in hard/aggressive water areas).

Space should left above the cylinder to allow anode replacement.

Reset timer Your system is equipped with a reset timer to ensure the pump does not

run continuously. This may occur if for some reason the Rinnai continuous

ow water heater does not ignite.

The timer will shut off the pump every 15 minutes for a few seconds to

ensure the continuous ow water heater resets itself.

Customer Information - For Your Safety

Scald Hazard Hot water can cause scalds

Children, elderly and disabled are the highest at risk of being scalded

Feel the water temperature before bathing or showering

Scalds from hot water taps can result in severe injuries

Scalds can occur when children are exposed directly to hot water when

they are placed into a bath which is too hot

•

Hydrogen Gas If the hot water is not used for 2 weeks or more, a quantity of hydrogen

gas which is highly ammable, may accumulate in the storage tank.

To dissipate this safely, it is recommended a hot tap (non electrical) be

turned on for 2 minutes at a sink, basin or bath. During this procedure

there must be no smoking, open ame or any other appliance operating

nearby.

If hydrogen is discharged through the tap, it will make a sound like air

escaping.

Safety Devices

WARNING

Your system is supplied with various safety devices including temperature

sensors, overheat sensors/switches and a Temperature & Pressure Relief

(TPR) valve.

Do Not:

Tamper or remove safety devices

Block or seal the TPR and drain pipe

Operate the system unless all safety devices are tted and in working

order

•

Legionella

Protection

Your system has been preset with specic temperature settings to disinfect

water for Legionella. Do not adjust these unless instructed by an authorised

person.

Flue Outlet of

Water Heater

Do not touch or insert any objects in the ue outlet.

Keep ammable materials, spray cans, fuel containers, trees, shrubs, pool

chemicals etc clear of the ue outlet.

If ue product discharge causes annoyance, an upwards or sideways ue

diverter can be purchased as an accessory.

Customer Information - Maintenance

Your Rinnai Demand Duo Lite requires little maintenance, but for maximum performance the

following is recommended.

Temperature &

Pressure Relief

Valve (TPR)

Normally only occurs during installation or servicing and must be carried

out by an authorised person.

Draining and ushing the cylinder on a yearly basis is recommended if

the water supply contains excessive levels of silt.

This valve is located near the top of the tank and is essential for safe

operation. Every 6 months operate the easing gear to ush the valve. As

this will discharge hot water, ensure no one is near the drain line.

It is very important that you raise and lower the easing gear gently.

During this operation, if the valve does not discharge water when the

easing gear is lifted, or does not seal again when closed, attendance by

an authorised person must be arranged immediately.

lift until water ows

from drain line,

lower gently

During servicing the TPR valve needs to be checked and/or replaced.

This needs to be done by an authorised person at intervals not

exceeding 5 years, or more frequently in areas where the water is

classied as hard.

Draining and

ushing of the

cylinder

Inlet water lter should be cleaned regularly.

Rinnai continuous

ow water lter

Storage tanks manufactured from metal can be susceptible to corrosion.

The combined effects of water pressure, temperature and water

chemistry can create an aggressive environment for corrosion of some

materials. For this reason anodes are placed in glass lined tanks so as to

corrode rst. They should be changed every 5 years (more frequently in

hard/aggressive water areas).

Customer Information - Troubleshooting

Lack of hot water or no hot water

Is there electricity

to the system?

Check isolating switches and electrical connections to ensure everything

is turned on.

Check the fuse or circuit breakers at the meter box. Repeated failure

of a fuse or tripping of a circuit breaker indicates a fault which must be

investigated by a licensed tradesperson.

Cold Water Relief

Valve discharging

continuously?

It’s normal for the Cold Water Relief Valve to discharge a small quantity

of water through the drain line. If water is discharging continuously

there may be a fault with one of the valves, contact your installer to

discuss.

High electricity/gas bills

If you think your electricity/gas bill is too high, investigate the following:

There may have been a change to your tariffs since your last bill

Cold Water Relief Valve is discharging continuously, refer above

You may be using more hot water than you think

There may be hot water pipe/tap leakages, check with your local plumber

The tank thermostat may not be set to 65 °C

•

Is the gas on? If the gas supply has been interrupted the water heater will display er-

ror code 11 or 12. Turn off the power to the system, wait 10 seconds

before turning on again.
