3.0Operating the Boiler

3.2Temperature Control

1.Central Heating: The central heating hot water flow temperature can be adjusted between 30° C (± 5° C) minimum and 85° C (± 5° C) maximum.

2.Turn the control knob clockwise to increase the temperature (Fig. 9).

3.In normal winter usage we recommend that the central heating temperature be set at maximum.

4.Domestic Hot Water: The temperature of the domestic hot water can be adjusted by turning the control knob clockwise to increase up to a maximum of 65° C (Fig. 10).

5.The temperature of the water is also dependent on the water flow rate and the temperature of the mains coming into the house.

6.By slightly reducing the flow from the tap the temperature will increase up to the maximum if required.

7.The flow rate can be reduced down to as low as 2.5 litre/min. The boiler will still recognise the need to heat the water.

3.3Flame Failure Reset

1.The red flame failure neon ( ) will illuminate in the event of the burner failing to light, when incomplete

lighting of the burner occurs or blockage of the condensate drain (Fig. 11).

2.Turn the selector switch fully anti-clockwise against the spring pressure to the ‘Reset’ position for at least two seconds and release (Fig. 12). Set the selector to the required position to light the boiler.

3.If the flame failure light illuminates repeatedly a fault is indicated with either the boiler, the gas supply or the condensate drain. Your installer or Service Engineer should be contacted as soon as possible.

3.4Safety Thermostats

1. Your Baxi Combi 105 HE is fitted with additional safety devices, which shut down the boiler in the event of the system, the boiler or the flue overheating. The

safety thermostat neon (	) will light in this instance
(Fig. 11).

2. To reset: Turn the selector fully anti-clockwise against the spring pressure to the ‘Reset’ position for at least two seconds and release (Fig. 12). Set the selector to the required position to light the boiler.

3. If after turning the selector to the ‘Reset’ position the boiler does not relight or the safety thermostat operates repeatedly, causing boiler shutdown, a fault is indicated. Your Installer or Service Engineer should be contacted

as soon as possible.
