Installation
Install only on an external wall, as close as possible to the most frequently used hot
tap. Use a heat shield (accessory item part number 9 708 061 400) if the unit is to be installed
on a combustible surface. Allow minimum air gap of 10 mm between the flue and the heat
shield, (refer figure 2).
Ensure that the flue terminal is clear of any combustible material, and avoid
installation in a marine environment.
Install the appliance such that the base of the appliance is not more than 1.3 metres
and not less than 0.5 meters from the ground, and allow for easy access to service heater.
Secure heater to wall using two 10g X 5/16 hex head wood screws (Ramset 610041 or similar).
Locate head of screw in the key hole of the top mounting bracket.

Pipe Connections
Refer to Fig. 1 for locations
Hot and Cold water ½" male
Natural gas ¾" female
L.P. gas ½" male
A gas cock must be installed in the gas supply line with provision to disconnect the
appliance. Install gate valve or full flow ball valve (fixed mechanism type) in cold water supply.
A non return valve must not be fitted. Example duo valve
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.
Water Temperature Adjustment
Located inside the water heater, immediately below the gas controls, is a water
temperature selector knob.
To increase the water temperature ( decrease water flow ) turn the knob clockwise. To reduce
water temperature ( increase water flow ) turn the knob anti clockwise.

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 0° 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
Open all hot water taps to expel any air prior to lighting
Remove front cover by loosening the two screws at the lower rear corners of the cabinet.
Check that gas and water valves are open, operate as indicated in Fig. 3
Refit front cover and tighten screws
Fig. 3
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.

Commissioning
Gas Inlet Pressure Adjustment
With the gas supply turned off, remove sealing screw from inlet pressure test point located on
the right hand side of the gas section refer Fig. 4 pos.A, attach manometer. Turn on gas and
light heater. Open hot water tap fully and adjust gas pressure regulator to 1.13kPa for NG
or 2.60kPa for LPG. Turn off gas and water, remove manometer, replace sealing screw
and test for escape.
Gas Burner Pressure Adjustment
Turn off gas supply, loosen captive screw in burner pressure test point, left hand side of
burner manifold refer Fig.5 Pos A, attach manometer turn on hot water tap fully and check
pressure.
Adjust pressure by turning the knurled wheel clockwise to increase gas pressure, anti
clockwise to decrease. refer Fig 4 Pos.E

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.
