Points to note 12 Months Free Warranty - register today To receive your 12 months free warranty please complete the form supplied with the boiler or simply call heateam, the service division of Baxi Potterton on 08706 000 653 or visit our web site on www.
Operating the Boiler The Central Heating and Hot Water you need will be available when the gas and electricity supplies to the boiler are turned on with the timer and other heating controls in your system set correctly. Other heating controls are items such as room thermostats, cylinder thermostats and thermostatic radiator valves. To give the most energy efficient performance these controls can switch your boiler on and off even when your timer is on.
Fault Indication A Off Fast Flashing (2 every second) On Burner On Flame Failure Power On 1. Your Main Combi 24 HE has three neon indicators. The upper two function as boiler on and fault indicators. 2. Depending on the nature of the fault the upper two neons will illuminate, go off or flash. 3. There are five possible combinations, each indicating one or more fault conditions. These are described below.
Temperature 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. 6). 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. 7). 5.
Central Heating System Pressure Pressure Gauge 1. The water pressure in the central heating system is indicated by the pressure gauge. 2 1 3 4 0 bar Fig. 8 Normal Pressure (when cold) 2 3 1 2. With the system cold and the boiler not operating the pressure should be between 0.5 and 1.0 bar. During operation the pressure should not exceed 2.5 bar, and will normally be between 1.0 and 2.0 (Figs. 8 & 9). 3. A pressure of 3 or greater indicates a fault.
