PRE-COMMISSIONING CHECKS APPLIANCE CAUTION: ISOLATE THE MAINS ELECTRICAL SUPPLIES BEFORE STARTING ANY WORK AND OBSERVE ALL RELEVANT SAFETY PRECAUTIONS. 3 1 Check that the service and water pipes are connected correctly. 2 Check that the oil supply is kerosene and that the pipework is connected correctly to the oil pump. Check that the burner is seated correctly on its mounting. Turn on the main oil supply valve at the tank, check the oil supply pipework and connections. 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 feed and expansion cistern and allow the system to fill. 2 Sealed systems only: Check and if required, adjust the expansion vessel pressure using the Schraeder type valve (C). 2 1 - 2 bar Fill the system to between 1 and 2 bar pressure via a WRAS approved filling link.
STARTING THE APPLIANCE IMPORTANT: Never run the appliance when the appliance/system is unpressurised (sealed systems) or empty. POWER SWITCH 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 2 Fit a suitable pressure gauge to port (A) on the oil pump. 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. If changing the burner output, check the position of the air damper disc is correct to the output as shown in the table below.
STARTING THE APPLIANCE B 1 C A IMPORTANT: The burner has an 11 second delay before the motor is activated. 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. 2 Set the room thermostat to minimum. The burner and circulating pump should be off. 3 Check that any other controls that are fitted to the system are operating properly.
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. B B 2 A A C FLUSHING (Central Heating): 1 Switch off the boiler. Open vented systems only: turn off the water to the system header tank. Open all radiator valves/drain cocks (B) and drain the system while the appliance is hot. Close drain cocks (B).
FINISHING COMMISSIONING APPLIANCE A 1 B 1 Locate the top rear edges of panel (A ) onto the supporting tabs ( B ) and drop the front panel carefully into position over the appliance. Push gently into place taking care to apply any pressure at the edges of the panel to avoid accidental damage Lift the bottom panel (C) into place beneath the boiler and engage the front lip with the bottom of the front casing.
INSPECTION AND SERVICE 1 B B CAUTION: ISOLATE THE WATER, ELECTRICAL AND OIL MAINS SUPPLIES BEFORE STARTING ANY WORK AND OBSERVE ALL RELEVANT SAFETY PRECAUTIONS.
INSPECTION AND SERVICE Clean the Burner: Remove the air intake cover (A) and clear any debris from the air intake and air damper. Disassemble the burner to allow access to the fan impeller. Check the condition of the gaskets between these parts and replace if necessary. Note the position of the air damper adjustment and check the air damper moves freely. Clean both sides of the fan impeller and remove any debris from the burner housing. Check that the impeller rotates freely.
INSPECTION AND SERVICE External oil filter: Remove the paper element from the external oil filter and replace it. If the filter contains a washable element, thoroughly clean in kerosene and reassemble into the filter.

In the unlikely event the boiler does not give complete satisfaction, before calling for a service engineer, the installer should check the following:General checks 1. Is there 230V across the boiler live and neutral terminals? 2. Is the polarity correct? (230V across live and earth, 0V across neutral and earth) 2. Is the air bled from the primary system? 3. Is the air bled from the oil supply? 4. Is the flue sized and routed correctly? Boiler runs straight to lockout 1.
