Aga Gas Fired ranges are delivered unassembled. Before installation can be made the site is inspected for suitability by an Authorised Aga Distributor and corrected where necessary to conform with local installation codes or in the absence of local codes with: In Canada: The CAN/CGA-B149 installation codes. In U.S.: The National Fuel Gas Code NASI Z223. 1-latest edition. Assembly is undertaken on site by the same Aga Distributor to ensure correct performance and safety. BASE OR HEARTH It is essential that the base or hearth on which the range stands should be level and strong enough to support the total weight of the range. Approximate weight:- 3-Oven Model GC3 (Open Flue) - 477 kg (1049 lb) The top face of the hearth must be of non-combustible material for a minimum thickness of 12mm (1/2in) and comply with current Building Regulations and National Fire Laws. OPEN FLUE RANGE - MODEL GC3 (THREE OVEN) The wall behind the cooker draft hood and flue connector must have a minimum air gap of 57mm (2 1/4"). Any openings in the wall behind the range or in the floor under the range must be sealed before appliance installation. Ensure the draft hood is securely bolted to the support spigot as shown in Fig. 2. NOTE: THIS IS NORMALLY FITTED AND SECURED BY THE FACTORY BEFORE DESPATCH. The wall behind the range must be the outside wall for the venting of flue products. Recommended amount of make-up air into the room = 170ft3/hr Fig 1. Open Flue Model GC3 DESN 512843 Fig 2. Section Through Downdraught Diverter A VENT CONNECTION A 100mm (4in) Type B Gas Vent must be used and fastened by screw to the draft hood flue collar. U.S. The gas vent must be connected to a chimney or independently and in accordance with Chapter 26, chimney, Gas Vent and Fireplace Systems of the current issue of Equipment and Volume of the ASHRAE Handbook. The gas vent proximity to combustible materials must be installed as recommended in ANSI/NFPA 211 and according to manufacturers instructions. Chimneys and vents shall terminate above roof level and in accordance with the requirements of the current issue of ANSI/NFPA 211 (see diagrams) and be at least 1.53m (5ft) above the flue collar of the draft hood outlet. Part 7, Venting Equipment, outlined in the current National Gas Code NASI Z223, outlined in the current guidelines on all these aspects. Canada: The gas vent must be connected to a chimney or independently and in accordance with the CAN/CGA - B149 installation codes. The air gap between vent and combustible materials must be given for the following types of vent: (i) Type B Vent - 25mm (1in) minimum. (ii) Single wall vent connector - 150mm (6in) minimum. Listed connectors passing through the combustible walls and partitions must be guarded by a ventilated metal thimble not less than 200mm (8in) diameter. Chimneys and vents shall terminate above roof level and in accordance with the requirement of the current issue of the CAN/CGA - B149 Installation Code (Code W) (see diagrams) and be at least 1.53m (5ft) above the flue collar of the draft outlet. 1. If suitable lined brick chimney is used it must be swept before connection and not less than 150mm (6in) internal diameter. 2. The top of the chimney should be fitted with an approved Terminal. 3. The flue route to the chimney should be as direct as possible. Resistance in the form of directional change should be kept to a minimum. Right angle bends and horizontal runs should be avoided. 4. The chimney terminal should terminate at the highest possible point, preferably in a freely exposed position. Termination at the roofs eaves is unacceptable. 5. The Aga Distributor or Local Gas Company should be advised where any doubt as to the suitability of the flue. 6. Approved factory made chimneys are acceptable with the appliance and should not be less than (4in) internal diameter. 7. In the event of an extractor fan being fitted in the vicinity of the range, compensatory ventilation will be required to satisfy the demands of the fan without influencing combustion efficiency or chimney flue condition. Fig 3. WALL TILING If the cooker is to stand in a recess or against a wall which is to be tiled in no circumstances should the tiles overlap the range top plate.
