DESN 511053 4 AIR SUPPLY THE HOT WATER SYSTEM Kitchen or Internal Space Air Supply Where the appliance is to be installed in a kitchen or internal space, it does not require the kitchen or internal space containing it to have a permanent air vent. INSTALLATION PIPES Installation pipes should be fitted in accordance with current Gas Regulations. Pipework from the meter/tank to the cooker must be of adequate size, cooker connection size of 15mm Dia. On completion test the gas installation for soundness and purge in accordance with current Gas Regulations. ELECTRICAL A 3Amp 230V~50Hz fused electrical supply is required adjacent to the appliance. External wiring to the fan unit must be installed using a 3 core heat resisting 85°C PVC sheathed cable and in accordance with the current Wiring Regulations and any local regulations which apply. The wiring should be completed as indicated: The method of connection to the mains electricity supply must facilitate complete electrical isolation of the appliance, preferably by the use of an unswitched shuttered socket outlet in conjunction with a fused three pin plug. Alternatively, a fused double pole switch, having a contact separation of at least 3mm in both poles, serving only the appliance may be used. (Models GCB and GEB Only) In a domestic hot water system, the hot water storage vessel must be of the indirect cylinder of calorifier type. The hot water storage vessel should be insulated, preferably, with not less than 75mm thick mineral fibre, or its equivalent. Pipework not forming part of the useful heating surface should be insulated to help prevent heat loss and possible freezing, particularly where pipes are run through roof spaces and ventilated under floor spaces. Cisterns situated in areas which may be exposed to freezing conditions should also be insulated. Draining taps must be located in accessible positions which permit the draining of the whole system, including the boiler and hot water storage vessel. Draining taps should be at least 15mm nominal size. The use of horizontal pipe runs should be avoided wherever possible in order to prevent the collection of air in the system. If horizontal runs are unavoidable, the pipes should rise upwards in the direction away from the boiler. Hot water systems should be in accordance with the relevant recommendations. Water Circulation System (Models GCB and GEB only) The cooker boiler should be connected to a cistern water supply and subject to a maximum head of 18.25m and minimum 1m. The 28mm minimum diameter primary flow pipe must rise continuously from the cooker boiler to the cylinder to ensure good gravity circulation and have an open vent. The 28mm diameter primary flow and return pipes must not exceed 5.5m in length and be well insulated. Water Connections (Models GCB and GEB only) The two 28mm copper flow and return pipes from the boiler can be obtained for right or left hand connections. Hot Water Storage Vessel It is recommended that an indirect 190 litre (40 gallon) hot water storage cylinder of the double feed type should be lagged and fixed vertically as near as possible to the cooker. The water draw-off pipes to the taps must be dead leg connection from the vent/expansion pipe. A drain tap must be fitted at the lowest point of the system. Cooker Boiler Heat Exchanger The heat exchanger must be connected to a 190 litre (40 gallon) copper double feed indirect cylinder. 5 6 COMMISSIONING LIGHTING THE BURNER - Fig. 2 CAUTION: NO SMOKING OR NAKED LIGHTS Open the outer burner door to expose the gas control combination valve. CAUTION: BEFORE LIGHTING: ENSURE THAT THE GAS VALVE CONTROL KNOB 2 IS SET IN THE OFF POSITION (SEE FIG. A) AND COMBUSTION DISCHARGE SAFETY DEVICE BUTTON IS FIG A DEPRESSED. 1. Turn off union gas cock 1. Test the gas installation from the meter cock for s...
