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 Pre-Heat: To enjoy optimum performance of the boiler the pre-heat control should be set fully clockwise to the ON position (Fig. 10). When there is a demand for hot water it will be supplied at approximately 65° C instantaneously. 5. Turning the control 15° clockwise from the OFF position will activate the pre-heat feature. Hot water will be supplied at approximately 35° C instantaneously. 6. To increase the temperature turn the control further clockwise. For example, when set 90° clockwise the boiler will supply hot water at approximately 44° C instantaneously. At a position 180° from clockwise (i.e. straight down) the hot water will be supplied at 52° C instantaneously. 7. When the control is set anywhere between 15° clockwise from the OFF position and the ON position, the pre-heat feature will operate. 8. With the control in the OFF position (Fig. 11) the preheat feature will not operate. Hot water will be supplied at approximately 50° C. 9. The pre-heat feature will function with the selector switch in either operating position. This is indicated by the domestic hot water mode neon flashing (Fig. 12). 10. 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. 3.3 Flame 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. 12). 2. Turn the selector switch fully anti-clockwise against the spring pressure to the ‘Reset’ position for at least two seconds and release (Fig. 13). 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 called as soon as possible.

Your Baxi Combi Instant 80 HE or 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. 14). 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. 15). 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. 3.5 Air Flow Monitor 1. The boiler is fitted with an air pressure sensing device. This monitors the flue system. 2. If the neon illuminates ( ) it indicates that the flue or flue terminal is blocked or obstructed in some way, or that there is an internal fault. If there is no external blockage of the flue terminal that can be easily removed contact your Installer or Service Engineer (Fig. 14). 3.6 Pump Fault or Low Pressure 1. The neon ( ) will illuminate if the circulating pump is faulty or the system pressure drops below the minimum requirement (Fig. 14). 2. Check the pressure gauge as described in Section 3.9. If the pressure is in the normal range, a pump fault is indicated. Contact your Installer or Service Engineer to determine the nature of the fault. 3.7 Sensor Fault 1. When the ( ) or ( ) neon is illuminated a fault on the hot water or central heating temperature sensor is indicated (Fig. 14). Contact your Installer or Service Engineer. 3.8 Pump Protection 1. With the selector switch in either Position (i) or Position (ii) (Figs. 16 & 17) the pump will automatically operate for 1 minute in every 24 hours to prevent sticking. 3.0 Operating the Boiler 9 3.9 Central He...
