Benchmark has been introduced to improve the standards of installation and commissioning of central heating systems in the UK and to encourage the regular servicing of all central heating systems to ensure safety and efficiency. THE LOG BOOK SHOULD BE COMPLETED AFTER EACH SERVICE AND KEPT WITH THESE INSTRUCTIONS (button) CONTROL OF CH TEMPERATURE The output temperature of CH water is adjustable from a minimum of about 38°C to a maximum of about 85°C by turning the knob C. Approx CH flow temperatures for the boiler thermostat settings: Minimum (38 ° C) C Maximum (85 ° C) CONTROL OF DHW TEMPERATURE (Mini C24, Mini C28 and Mini C32) The temperature of the DHW leaving the boiler can be varied from a minimum of about 35°C to a maximum of about 55°C (within the power limits of the appliance) by turning the temperature control knob B. Minimum (35 ° C) B Maximum (55 ° C) Adjustment of the DHW temperature is completely separate from that of the CH circuit. The adjustment system integrated within the boiler automatically controls the flow of gas to the burner in order to keep the temperature of DHW delivered constant, between the limits of maximum and minimum output. Where the demand is at a low level or with the temperature set to the minimum, it is normal to see a cycle of lighting and extinguishing of the burner when running. Adjustment It is advisable to adjust the DHW temperature to a level commensurate with the demand, minimising the need to mix with cold water. In this way, the automatic control facilities will be fully exploited. Moreover, where the amount of limescale present in the water may be particularly great, not exceeding the position as shown in the following illustration (about 50 ° C) minimises annoying incidences of scale deposits and clogging. B In these cases, however, it is advisable to install a small water treatment device or softener. With such a device you should avoid periodic descaling. Consequently, the DHW heat exchanger will keep its performance consistent for a longer period of time with resulting gas savings. TO SHUT DOWN THE BOILER For short periods To turn the boiler off set the function selector C to the O position. The appliance On lamp A will flash every 4 seconds. For long periods When you do not expect to use the boiler for a long period: 1 Switch the the electricity supply off. 2 Shut off the gas supply cock and the valves for the water circuits fitted under the boiler. 3 If necessary, empty the water circuits. FROST PROTECTION Mini C24, Mini C28 and Mini C32 appliances are provided with a built in anti---freeze system that operates the boiler when the temperature is below 4 ° C Therefore, when the boiler is not lit and used in cold weather, with consequent risk of freezing do not isolate the boiler from the electricity supply or close the gas inlet cock. ESCAPE OF GAS Should a gas leak or fault be suspected contact your local gas supplier without delay. Do not search for gas leaks with a naked flame. CLEANING For ...
