[. . . ] R Fulton Boiler Works (Great Britain) Ltd. OPERATOR, SERVICE & PARTS MANUAL SERIES 'E' - GAS FIRED STEAM BOILERS (6E - 60E) GFSE-Std-0202 WARNING Steam Boilers are a potential hazard possibly fatal if not properly maintained. CAUTION It is vitally important that the instructions given in this manual are strictly adhered to. Failure to carry out the daily, weekly, monthly and six monthly checks could result in a drastic reduction in the life expectancy of the boiler. NOTE The Pressure system and Transportable Gas Containers Regulations 1989 Fulton Boilers fall within the scope of the Pressure Systems Examination Scheme and Section 40 of the Health and Safety at Work Act, 1974. Regular inspections are therefore required by a 'Competent Person' at intervals not exceeding 14 months. The scope of the examination and the actual intervals between examinations is at the discretion of the competent person.

Where original equipment Service Manuals are supplied, they must be read and understood in conjunction with this manual. All Warnings and Cautions must be observed. 3. 2 BOILER CONTROLS The following brief description of the controls used on the Series E gas fired boiler is intended to provide the operator with a basic understanding of the operating principles, which is essential for the continued efficient operation of the boiler. Note: All the controls are of the `fail-safe' type and are wired in series; failure of any one will automatically shut down the boiler. Low Water Relays and Feedwater Pump Relays. These relays operate in conjunction with probes suspended in the boiler and water column to automatically maintain the level of water in the boiler and to cut-off the burner should the water level fall to an unsafe level. Located on the control panel box and connected to the steam pressure gauge assembly by copper tube, the pressure regulator controls the on/off cycle of the burner, shutting the burner off when maximum pressure is reached and switching it on when the steam pressure falls. This is the main control in the panel box. The programmer in conjunction with a sensing device `supervises' the ignition sequence, proves the flame is satisfactory and finally `monitors' the established flame. Should any fault occur, either during the ignition sequence or during normal running, the programmer will immediately go to `lock-out' and both main and pilot gas valves will be closed. Mounted on the burner scroll, this switch is operated by the pressure of air entering the burner through the throat of the scroll. Lack of air, or insufficient pressure, will prevent the switch completing the circuit thus preventing the burner from operating. Consists of pilot and main gas supply lines, each line having a manual gas cock, a governor and electrically powered gas valves. The governors maintain a constant pressure of gas entering the burner and are adjustable. The electrically powered gas valves are controlled by the burner programmer.

The meaning and operating sequence of these lights is as follows: 3 Start/Low Water Reset This switch is used to start the boiler and to reset the low water alarm. When the switch is pressed to initiate the start-up sequence, the low water alarm lamp also illuminates and the low water audible alarm sounds.
