INTRODUCTION 8 716 106 253f 30/3/10 12:59 Page 4 SAFETY PRECAUTIONS OIL FUMES OR LEAKS FROM THE BOILER: Extinguish any naked flames. Open windows and doors. Switch off the boiler electricity supply. Isolate the fuel supply to the boiler. Contact installer/service engineer. IMPORTANT: This boiler must only be operated by a responsible adult who has been instructed in, understands and is aware of the boiler’s operating conditions and effects.

Optional programmer (see instructions supplied with programmer for details). Reset button - lock out (behind front panel)* * The alternative reset is accessed by removing the top panel on the boiler and pressing the reset button on the control box of the burner (see diagram below).
8 716 106 253f 30/3/10 12:59 Page 6 OPERATING THE BOILER SWITCHING THE BOILER ON/OFF: To switch on the boiler; turn on the water, oil and electricity supply to the boiler. Check the programmer/timer is correct and is set to ON. USING YOUR BOILER Set the room thermostat to the desired setting. Open and set thermostatic radiator valves as required. Turn the boiler water temperature control to the required setting.
8 716 106 253f 30/3/10 12:59 Page 7 OPERATING THE BOILER SETTING THE HOT WATER TEMPERATURE: Turn the control clockwise to increase the water temperature. Turn the control anti-clockwise to reduce the water temperature. USING YOUR BOILER A high setting will give a higher hot water temperature and greater quantities of hot water.
716 106 253f 30/3/10 12:59 Page 8 OPERATING THE BOILER PRESSURE GAUGE: USING YOUR BOILER The pressure gauge indicates the boiler/heating system water pressure and has two pointers: Red (external) pointer is set manually to indicate the normal system pressure (1 to 1.5 bar for sealed systems, 0 to 0.5 bar for open vent systems). Grey (internal) pointer shows the actual system pressure (on sealed systems the pressure will rise when the boiler/system heats up from cold).
8 716 106 253f 30/3/10 12:59 Page 9 OPERATING THE BOILER FILLING LINK: Sealed systems only If the sealed system pressure within your system drops to below 0.5 bar (shown on the pressure gauge) you will need to increase the pressure to ensure your boiler continues to run without problems. Your installer should have informed you where to find the filling system and instructed you in its use.
8 716 106 253f 30/3/10 12:59 Page 10 OPERATING THE BOILER (1) NORMAL OPERATION: FAULT CONDITIONS: ALL MODELS The POWER ON and LOCK OUT lights can indicate some basic fault conditions. USING YOUR BOILER (1) POWER ON light on, LOCK OUT light off: Normal operation Mains power supply to boiler. (2) POWER ON light on, LOCK OUT light on: Boiler not firing (2) BOTH LIGHTS ON: Check the level in the oil tank. Remove the front white panel on the boiler (see 5 below) and press the reset button (G).

8 716 106 253f 30/3/10 12:59 Page 12 MAINTAINING YOUR BOILER Your new boiler represents a long term investment in a reliable, high quality product. In order to realise its maximum working life and to ensure it continues to operate at peak efficiency and performance, it is essential that servicing and maintenance checks are performed at least once a year by an OFTEC engineer or other suitably qualified person.
8 716 106 253f 30/3/10 12:59 Page 13 SERVICING SERVICING: You must have the boiler regularly serviced by a competent, qualified OFTEC registered engineer using approved spares, to help maintain the economy, safety and reliability of the boiler. The boiler should be serviced once each year after installation unless the installation conditions and usage demand more frequent services. IMPORTANT:- Ensure that the service engineer completes the Service Record in the checklist after each service.
8 716 106 253f 30/3/10 12:59 Page 14 VENTILATION INFORMATION BOILER LOCATION: **The boiler can be installed under a worktop as long as: The worktop above the boiler is easily removable for maintenance. There is at least 10mm clearance above the boiler. The front of the boiler is not enclosed. VENTILATION: Air vents must be functional at all times and the air supply must not be restricted or contaminated. The boiler clearances must meet the minimum shown below for servicing and venting purposes.
8 716 106 253f 30/3/10 12:59 Page 15 VENTILATION INFORMATION Conventional flue boilers require an adequate supply of fresh air which must be delivered to the boiler for combustion purposes through a permanent inlet, such as an air brick, into the area where the boiler is situated. If a cupboard or compartment which is to be used for storage or airing is built around the boiler after installation there must be a non-combustible partition around the boiler.
8 716 106 253f 30/3/10 12:59 Page 16 GENERAL NOTES To get the best from your boiler. please read these instructions carefully. GENERAL INFORMATION SEALED HEATING SYSTEMS Where the boiler is fitted to a sealed heating system your installer will inform you of the minimum and maximum pressure which must be indicated on the pressure gauge. Check regularly that the pressure is maintained and contact your installer or maintenance engineer if there is a noticeable, permanent drop in pressure.
8 716 106 253f 30/3/10 12:59 Page 17 TIPS ON ENERGY SAVING Room thermostats: Reducing the setting of the room thermostat by 1°C can reduce fuel consumption by up to 10%. New control systems: Upgrade your heating control system with the latest equipment available. The minimum level of control for a heating system is a programmer, interlocking room thermostat and thermostatic radiator valves.
