2.0 Introduction

2.1 Introduction

1. Your Baxi Combi Instant 105e is a gas fired, room sealed, powered flue combination boiler, providing central heating for your home and mains fed domestic hot water to taps and shower. It is fully automatic and does not have a pilot light.

2. Priority is given to the hot water mode - when a hot water tap is turned on the supply of heat to the central heating circuit is interrupted.

2.2 Instant Domestic Hot Water

1. The boiler expansion vessel incorporates a small volume of stored primary hot water.

2. When the boiler has been off and there is then a demand for domestic hot water the stored primary hot water ensures that domestic hot water is supplied instantly at temperature.

3. The stored hot water is part of the primary circuit. This is not supplied as domestic hot water, which is fresh mains water heated by a heat exchanger within the boiler.

4. The stored primary hot water temperature is maintained whilst the boiler is in operation. During a period when there is no demand for heating or hot water the temperature of the stored primary hot water will eventually fall. The boiler will operate occasionally in order to maintain the temperature. This is indicated by the domestic hot water mode neon flashing (item 13 of Fig. 3).

2.3 Facia Panel

1. The facia panel is behind the hinged lower door. As well as the on/off/reset selector switch, central heating temperature control knob, pre-heat control and pressure gauge, the facia incorporates ten neon indicator lights.

2. Neons 12 to 15 indicate the operational status of the boiler. Neons 6 to 11 have a dual function, indicating the temperature of the central heating water when constantly illuminated. If a fault develops the appropriate neon will begin to flash. Refer to Sections 3.3 to 3.7.
