INTRODUCTION Thank you for choosing our condensing oil boiler, please read the following carefully. To the installer This manual must be left with the householder by the installer who will instruct the user on the boiler operation.
USER INSTRUCTIONS Reset Button BOILER OPERATION The Boiler Control Thermostat responds to the temperature of the water within the boiler and switches power to the burner when heat is required. The burner has an independent control system which regulates the firing and (shut-off) of the burner.
BOILER CONTROLS BOILER CONTROL THERMOSTAT The temperature of the water within the boiler is controlled and maintained by the Boiler Control Thermostat located on the boiler control panel. TEMPERATURE SETTINGS: The Boiler Control Thermostat has a range of 50°C to 80°C.
SWITCHING THE BOILER OFF The boiler can be switched off at anytime using one of the following: - Turn the boiler control thermostat to the OFF position - Switch the mains (electrical supply) to OFF - Set the control system to OFF (e.g. Time Clock) PLEASE NOTE: For longer periods of shutdown e.g. while away on holiday, switch OFF the mains (electrical supply) and turn OFF the OIL supply. If shutdown occurs during cold weather ensure boiler is protected against frost damage.
RESTART - Check there is adequate oil in the storage tank. - Check oil supply valves are open - Switch on heating system (e.g. Time Clock) - Press the Burner Reset Button on the burner Control Box, which will be illuminated. The Burner Reset Button (illuminated)(Fig 1) will go out and the burner will commence the ignition start sequence. After 15 seconds the Burner should fire normally.
REGULATIONS The installation of oil-fired boilers should comply with the following standards and codes of practice: - BS5449 Forced circulation hot water heating systems for domestic use. - BS5410-Part 1 Oil installations up to 45kw - BS7593 Water treatment of hot water central heating systems - BS7671 Electrical Regulations - Building Regulations Part 1L and J 2002 England and Wales, Part F Scottish Regulations and Technical Booklet L Northern Ireland.
BOILER LOCATION Sound levels should be discussed with the householder, as some people may be sensitive to low noise levels in a small room, as is may appear more annoying than in larger rooms. Please Note installation should take into account of flue position (see diagram). RECOMMENDED FLUE POSITION Issue No.1 Combined Manual 24.10.
OIL SUPPLY Issue No.1 Combined Manual 24.10.
OIL SUPPLY A flexible oil pipe is supplied to connect the burner to the incoming oil supply pipe. IMPORTANT NOTES: - If sitting oil tank above burner height, use single supply pipe only. - If sitting oil tank below burner height, use twin pipe supply or Tiger loop. - Please refer to Burner Manual for conversion to oil pump for two pipe system. Issue No.1 Combined Manual 24.10.
ELECTRICAL ENTRY The electrical supply to the boiler must be wired using a double pole-isolating switch 230v/50hz, fused 5 amps. The mains supply must be connected with the boiler dual stat, the supply will then continue down to the burner control box. The burner is supplied with a three wire cable plug which allows disconnection for maintenance. Issue No.1 Combined Manual 24.10.

COMMISSIONING & SERVICING INSTRUCTIONS A competent service engineer OFTEC registered should be appointed on an annual basis. • Isolate Power to the boiler • De-pressurise heating system and check expansion vessel pre-charge is the same as the cold fill pressure, of the heating system. Expansion vessel pre-charge must not exceed 1.5 bar.
BOILER WILL NOT START Check if mains electricity supply is reaching boiler control panel, making sure control thermostat is turned on and time clock is calling for heat. Mains indicator green should be illuminated. If green light is not illuminated and fuse has been checked then heating system charge may be low, check black needle on pressure, located inside boiler cabinet (top right hand side) is reading 1 bar or more. If not depressurised, refer to fault diagnosis. FAULT DIAGNOSIS Issue No.
NO HEATING OR HOT WATER - Check there is power to the boiler, has fuse blown? If yes replace and test, if fuse continues to blow check circulation pump is not passing heating water into circulation pump electrical box. Is the system pressure below 1 bar on black needle on pressure gauge? If yes recharge system pressure by opening the filling loop valve slowly, until black needle indicator reads (approx 1 bar) Green neon NOT illuminated. Place rocker switch to the ON position located on the control panel.
