Installation/Operating Instructions

Invented for life

This Bosch water heater is an external, electronically controlled gas water heater. This Bosch appliance is supplied set to operate without temperature selector pads at a constant 55°C outlet temperature. To set the appliance to a different temperature, refer to page 13 for details.

Available as optional extras are Main, Bathroom or Sub temperature selector pads.

Only one Main controller and one Bathroom controller can be connected to the appliance along with up to 2 x Sub-controllers.

The bathroom and sub temperature selector pads have a maximum temperature setting of 50°C for safety. To ensure compliance with Australian Standard AS/NZS 3500.4, in the bathroom area, this may be achieved by using a Bosch appliance limited to 50°C or using a Bosch appliance with a delivery temperature greater than 50°C and installed with a tempering valve (high performance). In New Zealand, please refer to the New Zealand Building Code and all other applicable electrical, gas fitting and plumbing codes.

Before installing this appliance, carefully check that all packing materials have been removed and that the appliance is correct for the gas supply to which it is to be connected

GAS CONNECTION

(1)Fit a union to the water heater gas inlet for easy connection and removal. The thread diameter is 20 mm.

THIS DOES NOT INDICATE THE SIZE OF THE GAS SUPPLY.

(2)Fit an AGA / NZGA approved isolating gas cock in the supply line adjacent to the water heater gas connection.

(3)Ensure that the supply pipe and the gas pressure regulator (LPG or Natural Gas) has sufficient flow capacity for this and other appliances connected to the fitting line.

(4)For LPG appliances ensure that gas cylinders are of sufficient size. The water heater alone will require 2 x 45 Kg capacity cylinders.

(5)Before connecting the appliance to the gas service, purge any debris or air from the gas service.

(6)Check all joints for leaks with an approved leak tester after connection.

Refer to AS 5601 Installation Code or NZ installation code for pipe sizing details.

Ensure that the gas pipe size is correct. If undersized the appliance will not operate correctly

SERVICE CALLS ARE CHARGEABLE FOR UNITS WITH INCORRECT PIPE

SIZES OR BLOCKED GAS OR WATER FILTERS.

COLD WATER CONNECTION TO WATER HEATER

Refer to technical sheet for position of connections. The WATER INLET connection is 20 mm 3/4" BSP and requires a union to allow for removal of the water heater. Pipe sizing from the cold water supply should be sized according to local BY LAWS for water supply.

If sludge or foreign matter is present in the water supply it is recommended that a separate filter/strainer be fitted to the cold water supply line.

Please ensure this appliance does not receive inlet water greater than 85°C when used as a Solar booster.

ISOLATING GATE VALVE

A GATE VALVE OR BALL VALVE must be used on the cold water inlet to the water heater. THIS REQUIREMENT IS AN AUSTRALIA WIDE REQUIREMENT UNDER THE NATIONAL PLUMBING CODE.

STOP TAPS OR COMBINATION STOP TAPS AND NON-RETURNVALVES ARE

NOT TO BE USED.

N.B. NO PRESSURE REDUCTION VALVE IS REQUIRED UNLESS THE WATER PRESSURE EXCEEDS 1000 kPa

Installation/Operating Instructions

HOT WATER CONNECTION TO WATER HEATER.

Refer to Technical Sheet for position of connection. The outlet connection is 20 mm (3/4" BSP) MALE thread, and requires an isolating union to allow for removal of the unit.

Keep the pipe lengths to a minimum, and make sure that the pipework is well insulated as correct performance of the appliance is dependent on properly insulated pipework.

DO NOT FIT ANY VALVES OR RESTRICTORS TO THE OUTLET OF THE WATER HEATER.

DO NOT FIT ANY OBSTRUCTION TO THE PRESSURE RELIEF LOCATED ON THE HOT WATER OUTLET CONNECTION.

After purging the air from the system using the hot water supply taps, remove the water inlet strainer located on the cold water supply inlet connection. Remove any debris from the filter and replace. When replacing the filter, do not over-tightenthe “O” ring seal.

In order to comply with AS3498 the minimum distances as per the diagram below must be observed.

These requirements are only for the 50°C locked units.

Closest hot water outlet

WARNING: For continued safety of this appliance it must be installed, operated and maintained in accordance with the manufacture's instructions.

ELECTRICAL CONNECTION

The appliance is equipped with a 1.7 metre cable with a three pinned earthed plug to be connected to a 240V, 50Hz supply. The electrical rating of the appliance is 0.4 Amps

The appliance requires a 240V in Australia and 230V in New Zealand, 50Hz weatherproof plug installed in a protected position adjacent to the appliance.

IMPORTANT: The appliance should always be disconnected from the power supply before any maintenance is carried out. If the power cord is damaged and requires replacement, use only an original spare part available from the manufacturer.
