Congratulations
Congratulations for choosing a Bosch HydroPower water heater. This appliance should give many
years of trouble free use, when installed to the specifications contained in this document.
The Bosch Story
Bosch Thermotechnology has
been delivering hot water to
Australia and New Zealand
families for nearly 50 years,
and forms part of the
worldwide Thermotechnology
division of Robert Bosch.
With global sales of 1.4
million water heaters every
year, Bosch provide hot
water solutions for every
water heating need.
Bosch pioneered continuous
flow water heating in the late
1800’s, and this tradition of
innovation and invention still
drives our company today.
Extensive research and
development ensures that
Bosch remains at the forefront
of water heating technology.
With an extensive product
range, Bosch strives to deliver
products designed to fit the
lifestyle of today’s modern
families.
Product Overview
HydroPower Ignition is exclusive to Bosch.
HydroPower uses the energy created by water flow to ignite the burner and begin the heating process.
The unit only starts when a hot water tap is opened. Once hot water is no longer needed, the unit turns
itself off.
1. Water enters the Hydro
Dynamic Generator
2. The turbine spins with water
flow
3. A spark is generated by the
turbine
4. The spark ignites the main
burner
5. The water continues on to the
heat exchanger and is heated
External HydroPower
External HydroPower models are perfect for a
constant, reliable supply of hot water. The
HydroPower ignition provides endless hot
water at the flick of a tap, without the need of
power point.
Versatile
• LPG models are particularly popular in
country areas, where reticulated gas is not
available and there is no external power
point.
• They are able to operate in relatively low
water pressure areas and in low
temperature regions of Australia and New
Zealand using Bosch accessories.
Economical
• Only heating water when required by the
user, the Bosch range is extremely
economical to run.
Internal HydroPower
Limited space need not mean limited hot
water. The Bosch range of internal hot water
heaters are created specifically to go places
where storage units will not, and will provide
endless hot water.
Versatile
• Operable without a power point
• Compact design
• Flexible connections
• Caters for a wide range of applications and
needs
Economical
• Only heating water when required by the
user, the Bosch range is extremely
economical to run.

Note:
Your water heating appliance requires a hot water flow rate of 3.5 litres per minute
and above to operate.
Water fixtures with a flow rate of 7.5 litres per minute or higher and Shower Roses of
9 litres per minute or higher are recommended.
Your water heating appliance is not to be used on Solar, Spa or recirculation
systems.

Adjust appliance with only one tap operating.
Starting and shutting off the appliance
To switch the appliance on, turn the on/off switch to position "1"
To shut off the appliance, turn the on/off switch to position "0"

Water Flow Adjustment
Turn anti-clockwise Water flow increases, temperature diminishes
Turn clockwise Water flow decreases, temperature increases.
Warning
If the appliance does not operate, burns with yellow flame, leaks water or a gas smell
is evident, turn off and contact the local gas authority, the manufacturer or an
authorised service person.
Freezing Weather
In areas where the atmospheric temperature may drop below 0°C the heater may be
drained to prevent damage by expansion of freezing water. For appliances installed
in locations where the temperature falls below 0°C and not less than -2°C for brief
periods, the installation of an EXOGEL expansion valve, part number H707 060 151,
will minimise the possibility of damage to the appliance.
This water heater MUST NOT be installed in areas where the temperature remains
below 0°C for extended periods.
CAUTION: It is recommended that for sanitary fixtures used
primarily for the purpose of personal hygiene that a temperature
control device be fitted (such as a tempering valve) as per
AS.3498

10 Basic Steps for Installation
1. Check cold water supply pressures, min & max as per table below.
Model BOSCH 10H BOSCH 13H BOSCH 16H
Minimum Inlet
Pressure for
maximum
water flow
Minimum Inlet
Pressure for
minimum water
flow
Maximum Inlet
water pressure*
* If Inlet water pressure exceeds 800 kPa then a pressure reduction valve MUST be fitted.
Where the pressure reduction valve is less than 3 metres from the hot water unit then it must
be fitted in conjunction with a cold water expansion valve. Failure to comply with this
requirement may void the warranty. The preferable location for the pressure reduction valve is
at the water meter.
2. Connection sizing as per table below.
Hot & Cold Water
Natural Gas
L.P. Gas
3. Determine most suitable location for appliance. Install only on an external wall, as close as
possible to the most frequently used hot tap. If the unit is to be installed on a combustible
surface use a heat shield (P/N 9708061400.ZG1). Allow a minimum air gap of 10mm between
the flue and the heat shield.
4. Secure the water heater to wall using two appropriate fasteners.
5. Locate and connect cold and hot water piping to hot water appliance. Install a gate valve or a
full flow ball valve (fixed mechanism type) in cold water line. If the water supply pressure
exceeds 800 kPa, install a pressure reduction valve. If installing a reduction valve fit a cold
expansion valve between the reduction valve and the appliance. PRV=500 kPa Cold
Expansion=700 kPa. Refer to AS3500.1 and AS5601-2004 for the relevant pipe size.
NOTE: Service calls for incorrect pipe sizing will NOT be covered under warranty.
6. Test Inlet Gas Pressure while unit is running, adjust regulator to give values in table
below.
Model BOSCH 10H BOSCH 13H BOSCH 16H
Inlet Gas Pressure NG 1.13 kPa 1.13 kPa 1.13 kPa
Inlet Gas Pressure LPG 2.75 kPa 2.75 kPa 2.75 kPa
Natural Gas: With the gas supply turned off, remove sealing screw from inlet
pressure test point located on the left hand side of the gas section, attach manometer. Turn on
gas , open hot water tap fully and adjust gas pressure regulator to 1.13 kPa . Turn off gas and
water, remove manometer, replace sealing screw and test for soundness.

LP Gas: No adjustment is provided at the appliance for inlet pressure, check cylinder
regulator and pipe sizing.
For LPG we recommend the installation of two or more supply cylinders and an auto change
over pressure regulator
7. Adjust Burner pressure. Turn off gas supply, loosen captive screw in burner pressure test
point, left hand side of burner manifold. Attach manometer, turn on gas and open hot water tap
fully, check pressure.
8. Minimum Gas Pressure Adjustment. Attach manometer to burner test point (see picture above)
Set water flow selector fully clockwise (hot position). Move gas slide to left side, single flame
symbol, open hot tap fully. Turn adjustment screw (Position C in picture below) located on
left hand side of gas valve at a 45° angle to correct pressure. Anti clockwise to decrease
minimum burner pressure.
