3 Oil Storage & Supply System 3.1 Fuel Supply Fuel Storage The tank should be positioned in accordance with the recommendations given in BS 5410:1:1997, which gives details of filling, maintenance and protection from fire. A steel tank may be used and must be constructed to BS 799:5:1987 and OFS T200. ! A galvanised tank must not be used. A plastic tank may be used and must comply with OFS T100. ! Plastic tanks should be adequately and uniformly supported on a smooth level surface, across their entire base area, that is, the area in contact with the ground. Fuel Pipes Fuel supply pipes should be of copper tubing with an external diameter of at least 10 mm. Galvanised pipe must not be used. All pipe connections should preferably use flared fittings. Soldered connections must not be used on oil pipes. ! CAUTION NOTE CAUTION Flexible hoses must NOT be used outside the boiler case. A remote sensing fire valve must be installed in the fuel supply line, with the sensing head located above the burner. Recommendations are given in BS 5410:1:1997. A metal bowl type filter with a replaceable micronic filter must be fitted in the fuel supply line adjacent to the boiler. A shut-off valve should be fitted before the filter, to allow the filter to be serviced. A flexible fuel line, adaptor and ¼" BSP isolation valve are supplied loose with the boiler for the final connection to the burner. If a two pipe system or 'Tiger Loop' type de-aerator is used, an additional flexible fuel hose (900 mm) and 3 / 8" to 1 / 4" BSP male adaptor are available to purchase from Grant UK, Part No. RBS36. Metal braided flexible hoses should be replaced annually when the boiler is serviced. Long life flexible hoses should be inspected annually and replaced at least every 60 months. Single pipe system - (See Figure 3-1) With the storage tank outlet above the burner a single pipe system should be used. The height of the tank above the burner limits the length of pipe run from the tank to the burner. As supplied the burner is suitable for a single pipe system Two pipe system - (See Figure 3-2) With the storage tank outlet below the burner, a two pipe system should be used. The pipe runs should be as shown in Figure 3-2. The return pipe should be the same level in the tank as the supply pipe, both being 75 to 100 mm above the base of the tank. The pipe ends should be a sufficient distance apart so as to prevent any sediment disturbed by the return entering the supply pipe. Avoid the bottom of the tank being more than 3.5 m below the burner. A non-return valve should be fitted in the supply pipe together with the filter and fire valve. A non-return valve should be fitted in the return pipe if the top of the tank is above the burner. To be used with a two-pipe system, the burner must be fitted with an additional flexible fuel hose - a flexible fuel hose (900 mm) and 3 / 8" to 1 / 4" BSP male adaptor are available to purchase from Grant UK), Part No. RBS36. The pump vacuum should not exceed 0.4 bar. Beyond this limit gas is released from the oil. For guidance on installation of top outlet fuel tanks and suction oil supply sizing, see OFTEC Technical Book 3. Available from OFTEC.
