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.

Conversion and Spare Parts

For spare parts or conversion of the heater to operate on a different gas that for which it was

originally manufactured, please contact your local gas authority, authorised service agent or

the manufacturer

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.
