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
