3.0Operating the Boiler

3.4Safety Thermostats

1.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.

3.5Air 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).

3.6Pump 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.

3.7Sensor 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.

3.8Pump 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.
