We recommend that all hot water pipes be lagged if the runs are long or exposed,
and water-proof lagging should be used on all external hot water pipes. If the water supply
pressure exceeds 80% of the specified maximum, install a pressure limiting valve.
If installing a pressure limiting valve fit a cold expansion valve between the limiting valve and
the appliance. PLV = 500kPa Cold expansion = 700kPa
Refer to AG 601 and AS3500.1 for the relevant pipe size.
NOTE: Service calls for incorrect pipe sizing will NOT be covered under warranty.
Water Filter
If sludge or foreign matter is or may be present in the water supply, it is
recommended that a suitable filter be incorporated in the water supply line to the heater. All
pipes should be well flushed before connection is made.
A water filter/strainer is installed in the inlet of the brass water valve inside the appliance.

Freezing Weather
In areas where the atmospheric temperature may drop below
0°C, the heater must be drained to prevent damage by expansion of
freezing water. For appliances installed in locations where the
temperature falls below zero ° C for brief periods , the installation of an
EXOGEL expansion valve, part number H 707 060 151, 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.

Operating instructions
Procedure to light the appliance.
Fig. 4
To ensure that the water, at maximum water flow, will be of adequate temperature for sanitary
purposes ( approx 40°C ), the appliance must be adjusted by the plumber at the time of
installation.
When hotter water is required, ie dishwashing, simply reduce the flow of water at the tap and
up to 60°C water will be delivered.
Refer to the commissioning section for adjustment details.
Warning -If the pilot light is extinguished, wait 5 minutes before attempting to relight the
appliance. 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.
When attempting to light the appliance ensure that all hot water taps are turned off.
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.

Commissioning
The two most important points are to set the maximum water flow rate and to ensure the
burner pressure is correct.
1. Water Flow
The water flow must be adjusted so that when a hot water tap is opened fully the appliance
has enough time to heat the water as it passes through the heat exchanger.
Open a hot water tap fully and adjust the water flow rate to the maximum rate.
Bosch 13P
Bosch 16P
13 litres / minute

In cool areas where the cold water temperature drops below 15°C in Winter it will be
necessary to set the water flow lower than the maximum rate.
Water Wizard 780
Water Wizard 960
8 to 10 litres / minute
10 to 12 litres / minute
Adjust using the slotted head screw in the base of the brass water valve. Refer Fig.5 Turn
screw clockwise to decrease flow rate (hotter water).
The time taken to fill a one litre container divided into 60 = litres a minute.
Example a one litre container fills in 6 seconds
60 ÷ 6 = 10 litres a minute.

Burner Pressure Adjustment
With the gas supply turned off, loosen the captive screw in burner pressure test point
( Position A Figure 6 ) on the left hand side of the burner manifold.
Attach a "U" tube manometer , turn on the gas supply and light appliance. Open a hot water
tap to draw off more than 10 litres a minute ( in summer or when the inlet cold water is above
15°C it may be necessary to temporarily increase the maximum water flow to compensate for
the thermostat turning down the gas rate )
Adjust pressure if necessary at the pressure regulator fitted to the gas supply pipe. (Refer
data page 3)

Figure 6
Inlet Pressure
The gas supply pressure must be as stated on the appliance rating label, located bottom right
hand inside rear panel. The gas pressure at the inlet test point ( Position A Figure 7) will be
approx 100 pascals less than the supply pressure due to the pressure drop across regulator.

Thermostat Setting
Method :Step 1.
Adjust maximum water flow to 10 -13 litres a minute
( Bosch 13P ) or 13-16 litres a minute (Bosch 16P ).
Adjust using the slotted head screw in the base of the
brass water valve. Turn clockwise to decrease water
flow ( higher water temperature ) .
Water flow can be measured by the time taken
( seconds ) to fill a container of a known quantity.
I.E.: A 2 litre container fills in 12 seconds
Therefore 60 ÷ 12 seconds × 2 = 10 litres a minute.
Water Flow

Step 2.
Loosen burner pressure test point and attach U tube manometer, light
appliance and open hot water tap fully. Measure the distance between the two
water columns.
1 KPa = 100 mm
2.6 KPa = 260 mm
Adjust natural gas appliances at the pressure regulator fitted to the gas inlet
pipe and LP Gas appliances are to be adjusted at the regulator fitted to the
supply cylinder.
If the burner pressure is not correct check the gas
inlet pressure at the test point located on the right
hand side of the gas valve . The inlet pressure
should be measured with the appliance operating.
Step 3.
With the manometer still connected turn a hot water

tap on to give a flow rate of 5 litres a minute ( fill a 1
adjustment nut
litre container in 12 seconds ).
Allow water to run for 1-2 minutes and measure temperature. Adjust to give an
outlet temperature of 60°C.
When an outlet temperature of 60°C is obtained ensure that the burner
pressure is lower than in step 2 , this will confirm that the thermostat is
sensing the hot water and closing the gas supply to give only the amount of
fuel required to achieve 60°C.
Now reduce the flow of water to a rate of 2 litres a minute, the temperature
should not exceed 63°C If incorrect replace flow thermostat insert.
Step 4.
After completing all the above adjustments open the hot water tap fully and
observe that the burner pressure returns to that stated on the rating label. This
will ensure that the thermostat is sensing the cold water and opening the gas
fully.
Remove the manometer and tighten the burner pressure test point.

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 b e 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.
