Overview of Condensing Gas Water Heater
This water heater is a high efficiency, fully condensing appliance. Unlike a traditional water heater, a
condensing type captures heat from the exhaust gas and uses it to preheat the incoming cold water
as it passes through the secondary heat exchanger as illustrated below.

The condensing gas water heater
discharges condensate.
When heat from the exhaust gas is collected
within the secondary heat exchanger,
condensation occurs from moisture in the
exhaust gas and the resulting water is
discharged from the drain pipe (approx. 75cc
/min. maximum). It is not a water leak. Do not
plug or block the drain line as it must always
be allowed to freely flow.
Drain pipe
(Installation example)
Condensate
comes out
from here.
The condensing gas water heater
tends to show white steam.
After the exhaust gas passes through the
secondary heat exchanger, it becomes low in
temperature and moisture rich which tends to
produce steam at the vent discharge terminal.
This is a normal occurrence.
8
During combustion, white
steam may often be seen.
This is normal.

Frost Protection
CAUTION
* Damage can occur from frozen water within the device and pipes even in warm environments.
Be sure to read below for appropriate measures.
* Repairs for damage caused by freezing are not covered by the warranty.
Freezing is prevented within the device automatically by the freeze-prevention heater
Freezing cannot be prevented when the power plug is unplugged. Do not remove the power
plug from the wall outlet.
(Freezing will be prevented regardless of whether the operation switch is ON or OFF.)
* The freeze prevention heaters will not prevent the plumbing external to the unit from freezing.
Protect this plumbing with insulation, heat tape or electric heaters, solenoids, or pipe covers.
Take the measures below for extremely cold temperatures*.
(outside temperature including wind chill factor less than -15°C)
This method can protect not only to the heater, but also to the water supply,
water piping and mixing valves.
Hot Water Fixture
1. Turn the unit off with the Operation Button on the Remote Controller.
2. Close the gas supply valve.
3. Open a hot water fixture, and keep a small amount of hot water running

(400cc / minute or about 4mm thick).
* If there is a mixing valve, set it to the highest level.
4. The flow may become unstable from time to time. Check the flow 30 minutes later.
* In general, it is not advisable to run water through the unit when it is OFF ( p. 6),
but in this case freeze prevention is more important.

Troubleshooting
Initial Operation

when water is running.
• Check for reversed plumbing or crossed pipes.
• Check the water drain valve filter. ( p.25)

• Is the water supply cut off?
• Is the heater frozen?
The hot water is not the correct
temperature.
Water takes time to become hot
when turning the hot water fixture.
• Is the hot water fixture sufficiently open?
The water is too hot.
• Are the gas and water supply valves fully open?
• Is the water temperature setting appropriate?
( p.16 and p.17)
• If the water supply temperature is high, it is possible
for the temperature to be higher than the temperature
set on the remote controller.
• If only a small amount of hot water is demanded, it is
possible for the temperature to be higher than the
temperature set on the remote controller.
The water is not hot enough.
• Are the gas and water supply valves fully open?
• Have you allowed enough time for the cold water in the
pipes to drain out?
• Is the water temperature setting appropriate?
( p.16 and p.17)

Operating Instructions
(Continued)
The water is cold when only a
single fixture is open.
• The unit will not heat the water if the flow rate is less than
2.5 litre per minute.
Open the fixture more or open other fixtures so that a greater
flow passes through the unit, and the unit should begin
heating again.
Fluctuations in hot water
temperatures.
• Set water temperature at 48°C to 50°C. This will allow you
to use a higher flow of hot water thus meeting the minimum
flow requirement of 2.5 L/min.
• Clean the water filter of any debris ( p.25)
Amount of Hot Water
The amount of hot water at a
certain fixture is not constant.
• When hot water is demanded at other fixtures, the amount
available may be reduced. The maximum flow available
from this unit is 26 L /min. at a 25°C temperature rise.
• Pressure fluctuations and other plumbing conditions can
cause the temperature and pressure at a fixture to be
unstable, but it should stabilize after a short time.
• There are some types of hot water taps that discharges large
volumes of hot water at first but stabilize after time.
• To keep the temperature stable, the heater limits the
amount of water that can flow through it to a small amount
initially, but the amount increases over time.
The amount of hot water in the
bath is less/more than the set
amount.
• When hot water is used for other fixtures while filling the
bath, the bath will not fill as much.
• If there is water in the bath already, or when filling is
stopped and restarted, the bath will fill more.
The flow meter alarm does not
sound even when filled to the set
amount.
• The flow meter alarm is set to sound when hot water
is continuously discharged for the set volume of water.
If mixing valves are used, or if cold water is mixed with hot
water at the fixture, the bath will fill more than the setting
of the flow meter alarm.
Amount of hot water available
has decreased over time.
• Is the water filter clogged? (

is. When leaving the protective sheet on, areas frequently
touched may tear or peel. However, the remote controller
will not malfunction from water entering such torn or
peeled areas. To restore the appearance of the remote
controller surface, simply remove the protective sheet.
Sounds
The fan can be heard after
operation is stopped.
A motor can be heard when turning
the unit ON or OFF, when opening
or closing a fixture, or after the unit
has been running for a while.
• These noises indicate the proper operation of devices
which are designed to let the unit reignite more quickly,
and ensure the water temperature is stable.

The hot water is turbid.
• This is harmless. Small bubbles appear as the air in the water
is heated and depressurized rapidly to atmospheric pressure.

• Coloration to a blue colour may be noticed from small traces of
copper ion contained in the water and fat (furring). However,
there are not problems concerning health. Coloration of the

WATER QUALITY
All Bosch water heating appliances are constructed from high quality materials and
components and all are certified for compliance with relevant parts of Australian and
New Zealand gas, electrical and water standards.
Whilst Bosch water heaters are warranted against defects, the warranty is conditional
upon correct installation and use, in accordance with detailed instructions provided
with the heater. In the case of the water supplied to the heater, it is important that the
water quality be of acceptable standard.
The water quality limits/parameters listed in water quality table are considered
acceptable and generally, Australian and New Zealand suburban water supplies fall
within these limits/parameters.
In areas of Australia and New Zealand where water may be supplied, either fully or
partly, from bores, artesian wells or similar, one or more of the important limits may well
be exceeded and the heater could, therefore, be at risk of failure.
Where uncertainty exists concerning water quality, intending appliance users should
seek a water analysis from the water supplying authority and in cases where it is
established that the water supply does not meet the quality requirements of the water
quality table, the Bosch warranty would not apply.
