PRE-COMMISSIONING CHECKS 1 3 CAUTION: ISOLATE THE MAINS SUPPLIES BEFORE STARTING ANY WORK AND OBSERVE ALL RELEVANT SAFETY PRECAUTIONS. 1 Check that the service and water pipes are connected correctly. Check that all unused sockets are capped. 2 Check that the oil supply is 28 sec Kerosene and that the pipework is connected correctly to the oil pump. Turn on the main oil supply valve at the tank and check the oil supply pipework, connections and rectify any leaks.
FILLING THE SYSTEM 1 1 Open all system and radiator valves. Turn on the water main stop cock. Open vented systems only; turn on the water to the system header tank and allow the system to fill. 2 Sealed systems only; Fill the system to between 1 and 2 bar pressure via a WRAS approved filling link. Check the expansion vessel pressure and adjust if necessary using the Schrader type valve. 2 1 - 2 bar 3 Vent all radiators, retighten when completed.
STARTING THE APPLIANCE IMPORTANT: Never run the appliance when the appliance/system is unpressurised (sealed systems) or empty. 1 1 Check the oil supply is correctly fitted and in good working order before turning on the oil supply valves to the boiler.
STARTING THE APPLIANCE 2 E 2 Fit a suitable pressure gauge to port (A) on the oil pump. Remove plastic cover from the burner casing. Adjust the air shutter (L) and pump pressure (B) as shown in the table opposite. The burner should ignite following a pre-ignition period of approx. 15 seconds.
STARTING THE APPLIANCE 1 1 Open all radiator valves. Set room thermostat to maximum. Set programmer to ON for CH. Turn the thermostat control (A) to 'max'. A The burner should be ON with the circulating pump. Ensure all radiators are heating up evenly and balance the system to the temperature difference required for the heating flow and return according to the heating load. Set the room thermostat to minimum. The burner and circulating pump should be off.
WATER TREATMENT 1 IMPORTANT: Debris from the system can damage the boiler and reduce efficiency. Failure to comply with the guidelines for the use of water treatment with the appliance will invalidate the appliance warranty. FLUSHING (Central Heating): 1 Switch off the boiler. Open vented systems only: turn off the water to the system header tank. 2 Open all radiator valves/drain cocks and drain the system while the appliance is hot. Close drain cocks.

Thank you for purchasing a Greenstar oil-fired condensing boiler from Worcester Bosch. The company prides itself on manufacturing boilers to the strictest quality control standards throughout every stage of production. INTRODUCTION EXCELLENCE COMES AS STANDARD Worcester Bosch has led the field in innovative appliance design and performance for more than 40 years. This heritage means all products are of exceptional quality and proven reliability.
INTRODUCTION GENERAL INFORMATION Read these instructions carefully to get the best from your appliance. CENTRAL HEATING SYSTEMS: During the first few hours of operation of the central heating system, check that all radiators are being heated at an even rate. THERMOSTATIC RADIATOR VALVES: It is recommended that this type of valve is fitted to all but one of the radiators (or at least those in the sleeping accommodation).
BOILER LOCATION: This boiler is only suitable for installing internally within a property at a suitable location onto a fixed rigid non-combustible surface at least the same size as the boiler and capable of supporting the boiler weight. INTRODUCTION GENERAL INFORMATION The boiler is not suitable for external installation unless a suitable enclosure is provided. Roof space installations must fully conform to BS5410 part 1 section 4.6.
INTRODUCTION GENERAL INFORMATION If a cupboard or compartment which is to be used for storage or airing is built around the appliance after installation there must be a non-combustible partition around the boiler. Further information can be found in BS 5410 which also describes venting requirements.

OPERATING THE APPLIANCE TEMPERATURE CONTROL: 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 it is set to ON Set the room thermostat to the desired setting USING YOUR APPLIANCE Open and set thermostatic radiator valves as required Turn the boiler water temperature control to the required setting To switch off the boiler; turn the programmer/timer to OFF for heating and hot water.
OPERATING THE APPLIANCE FROST PROTECTION: Use a suitable anti-freeze/inhibitor at the correct strength to protect against freezing USING YOUR APPLIANCE A frost thermostat should be fitted to the system where the system is most exposed and at risk of freezing. USER INSTRUCTIONS & CUSTOMER CARE GUIDE 8-716-106-257a (08.
OPERATING THE APPLIANCE FAULT CONDITIONS: The burner lockout indicator can indicate some basic fault conditions: Lockout indicator: a) Lockout indicator ON, boiler not firing; USING YOUR APPLIANCE A 1 Check the oil level in the oil storage tank 2 Press lockout indicator/reset button (B). Boiler should fire 3 If no response, wait 2 minutes - press lockout indicator/reset button (B) again 4 If lockout light stays on, do not attempt further resets. Contact your service engineer for advice.
TIPS ON ENERGY SAVING Heating economically: The boiler is designed to provide a high level of comfort while keeping oil consumption and the resulting environmental effect as low as possible. The central heating control on the boiler should be set as low as possible while still maintaining a comfortable room temperature. The temperature of each room can be set individually using the thermostatic radiator valves (except the primary room with the room thermostat).
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.
MAINTAINING YOUR APPLIANCE Your new appliance 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 a competent person beyond the initial guarantee period.
FAULT FINDING PROBLEM CAUSE Desired room temperature Thermostatic radiator Increase thermostatic radiator is not reached valve(s) set too low valve setting(s) Room thermostat set too low Desired room temperature Increase room thermostat setting Temperature control on Increase temperature control boiler set too low setting Air trapped in heating Bleed radiators and recharge system heating system Radiators are too hot Turn down thermostatic radiator exceeded by large amount MAINTENANCE
