5. Removal of the Cabinet and External Cover 4. Siting the Appliance 4.1 The appliance may be installed in any room although particular attention is drawn to the requirements of the current I.E.E. Wiring regulations BS 7671 and, in Scotland, the electrical provisions of the building regulations applicable to Scotland; with respect to the installation of appliances in rooms containing baths or showers.
3. The terminal must not cause an obstruction nor the discharge cause a nuisance as a result of either flue gases or terminal noise. 4. If the terminal is fitted within 600mm of a plastic/painted gutter or painted eaves then an aluminium or stainless steel shield at least 750mm long should be fitted to protect the surface. 5. If a terminal is fitted less than 2 metres above a surface to which people have access a terminal guard should be fitted.
Fig.8. Flue outlet terminating positions for oil-fired appliances NOTE: The dimensions given are for general guidance only. Other surrounding buildings or objects may affect the clearance of combustion products. An alternative flue terminal position should be sought when there is any possibility of a nuisance being caused by inadequate dispersal of flue products. Terminals should be positioned so as to avoid products of combustion entering into buildings. C.D. H.J.
8.6 If a single pipe system is employed then the tank must be positioned such that the oil level does not exceed 4 metres above the level of the burner oil pump and in addition the oil level must be at least 0.3 metres above the level of the oil pump. Should it prove impossible to site the tank below the 4 metres maximum oil level a head breaking device must be installed between the tank and the burner. 8.
8.11 The following components should be fitted in the fuel line between the storage tank and burner: 1. A manual isolating valve installed as close to the tank as possible. 2. A fire valve in accordance with BS799: Part 2 as shown in Fig. 9. The fire valve should be fitted externally with a fire detection element located within the appliance case. Use of a capillary type valve will allow a neat and simple installation. A suitable valve is the KBB manufactured by Teddington Controls Limited.
of 1 metre above the top of the highest point in the heating circuit. 9. Heating and Hot Water System 9.1 The appliance is suitable for connection to fully pumped conventional indirect hot water systems utilising an indirect double feed cylinder. This appliance is not suitable for use on gravity systems. 9.2 The flow and return sockets are located at the top of the appliance. From the inside of the property the flow pipe is on the right hand side and the return pipe is on the left hand side. 9.

10. Electrical The “S” plan provides complete control on installations having pumped circulation to both the domestic hot water and radiator circuits. 10.1 The electrical supply to this appliance must satisfy the latest edition IEE Wiring Regulations and any local regulations which apply. The domestic hot water and radiator circuits are independently controlled by two motorised valves via a cylinder thermostat and a room thermostat. Both thermostats switch the water circulator and the boiler on and off.

13. Remove the internal control box by undoing the two screws holding the facia to the internal control box and pivot the facia down. 14. There is an earth loom that connects the internal control box to the wall mounting duct, release the wire from the earth rivet inside the internal control box and push back through the hole in the back of the internal control box. 15. Undo the two remaining screws holding the internal control box to the boiler.
11.3 Reassembling the Appliance 1. From the outside of the property carefully insert the external duct into the wall mounting duct with the oil connection block on the bottom edge of the duct. 2. The wall thickness determines how far out of the outside wall the external duct protrudes. Set the external duct position by using table 6, fig. 4 and 23. rectly. Make any necessary adjustments to the external duct. Remove the cover and wall trim being careful not to move the external duct.

cause a hazard in the case of a fire. 11.6 Flue Installation 1. Attach the telescopic flue to the insulation box with the two wing nuts and washers. 2. Set the approximate flue length by sliding the flue locating slot onto the tab which protrudes from the external duct. 3. Fit the external cover and insert two fixing screws and washers, do not tighten. 4.
10. Check all of the air-ways to the burner are clear of any obstruction. off using the service switch checking that there is no after-spurting from the nozzle. This can be detected by oil saturation on the blast tube. If after-spurting occurs remove the burner from the boiler, unscrew the nozzle, and while holding the burner in a vertical position, fill the nozzle holder with oil. Refit the burner and continue to run the boiler for three minute periods until after-spurting stops. 12.5 Check the Burner 1.
debris. Discard the check valve if the holes cannot be cleared or if the unit is defective and replace with a new one. (e) Reassemble in reverse order. 14. Routine Cleaning and Inspection WARNING: The appliance is serviced and repaired externally. External equipment operated at 230volts should not be serviced or repaired under adverse weather conditions. 7. It is strongly recommended that the oil atomising nozzle be replaced at each service.
for this purpose on the base of the external duct to the right of the burner as shown in fig. 30. 4. Turn on the oil supply at both the oil tank and between the burner and oil filter. 5. Re-commission the burner as described in Section 12. 14.8 Re-commission the Burner. 1. Connect the flexible oil supply hoses to the connection block as described in Section 11.5.
