FLUE TERMINAL PLUME MANAGEMENT The flue discharge can be redirected allowing some plume management control, alternatively, a complete plume management system can be fitted to the flue terminal. 2 A Redirecting the flue discharge: Important: should you wish to use the plume deflector please use the additional grease enclosed to ensure that an adequate seal is retained. 1 1 Remove screws (A) and terminal end (B).
CONDENSATE, GAS & WATER CONNECTIONS CONDENSATE CONNECTION: H The condensate pump (G) fills up and periodically discharges through the flexible condensate pipe (H) between 200mm to 4500mm from floor level. After this point the condensate flows, due to gravity, down the 21.5mm plastic pipe to the outlet. Max. 4500mm Fit the bayonet connector on the end of the condensate waste pipe to the condensate pump. Push down and rotate clockwise until the connector is locked.
PRESSURE RELIEF VALVE OUTLET A B Fitting the pressure relief valve drain pipe: Connect a length of 15mm copper pipe (A) to the P.R.V drain pipe (B). C The P.R.V drain pipe (B) should be at least 15mm diameter and run down away from any electrics or other hazard. IMPORTANT: The pressure relief valve is a safety device for the boiler and if activated may discharge boiling water or steam through the P.R.V drain pipe.

IMPORTANT: AFTER COMPLETING THE APPLIANCE SERVICE THE CO/CO2 MUST BE CHECKED AND SET TO THE LIMITS IN THE SECTION “AIR/GAS RATIO”. INSPECTION & SERVICE If the Heat Exchanger requires cleaning: An accessory kit is available (No. 840) specifically designed for cleaning the heat exchanger. If required order 7 719 001 996. 2 Remove the cleaning access cover (B), seal (C) and metal plate (D) securing it, if present. 3 Unscrew the condensation trap cap and place a suitable container underneath.
INSPECTION AND SERVICE Burner: NOTE: On re-assembly, replace the seal Check that the boiler is completely isolated from the gas supply. C 1 A Remove the clips (A) and unscrew the castellated nuts (B). Remove springs. Unscrew and remove the two hexagon screws (C) securing the fan. D Slacken fully the rear securing bolt (D). E F B D G Remove the burner cover plate (E). 2 Remove the burner (F) and clean the components. Do not use a wire brush. Re-assemble burner in reverse order using a new seal (G).
CAUTION: TURN OFF THE GAS SUPPLY AND ISOLATE THE MAINS ELECTRICAL SUPPLY BEFORE STARTING ANY WORK AND OBSERVE ALL RELEVANT SAFETY PRECAUTIONS. DRAIN THE BOILER/SYSTEM WHERE NECESSARY AND PROTECT ANY ELECTRICS FROM WATER INGRESS DURING COMPONENT REPLACEMENT. IMPORTANT: Refit or replace any components removed from the appliance in the reverse order using new gaskets/'O' rings/sealant/heat transfer paste where necessary. Any 'O' ring or gasket that appears damaged must be replaced.
NOTE: A SERVICE TO THE FAN ASSEMBLY AND FLAP VALVE MUST NOT BE ATTEMPTED IF A CO/CO2 ANALYSER IS NOT AVAILABLE. REPLACEMENT PARTS Fan Assembly: Undo lower pipe union on gas pipe (E). Remove fan lead and earth connector. The earth connector has a positive clip fixing. A B Remove fixing screws attaching fan (A) to the burner cover (B). Remove fan (A) with gas pipe (E) and mixer unit (D). Twist mixer unit (D) with gas pipe (E) to separate from fan (A).
REPLACEMENT PARTS Sensors: Check that the appliance is electrically isolated. Central heating flow temperature sensor (A): Remove the connector. Release the sensor clip and withdraw the sensor. A Apply heat transfer paste to the replacement sensor. B Drain the system first: Safety temperature limiter (B): Remove the connectors. Unscrew the sensor. Tank sensor (C): Remove screws retaining plastic cover. Remove cover and disconnect 2 electrical connections. Unscrew 2 hexagon studs.
REPLACEMENT PARTS Domestic hot water heat exchanger: Before removing the heat exchanger, close the inlet valves, drain the hot water circuits and tank. A The pipe (A) may be removed between the flow sensor outlet and the plate heat exchanger to improve access to the rear connections. Undo the two screws securing the plastic housing to the heat exchanger. Remove the heat exchanger. To refit, follow the above in reverse. Ensure any seals that have been disturbed are replaced.
REPLACEMENT PARTS Electrode assembly: Switch off the master switch. Isolate appliance from the power supply. Move control panel into service position. Release 4 screws to remove inner case door. Remove the leads from the electrodes. Unscrew the two fixing screws (B) and carefully remove the electrode assembly (A). Replace and re-connect the assembly taking care not to mislay the inspection window. D E C F After re-assembly check CO/CO2 levels as described in the section “Setting the air/gas ratio”.
SETTING THE AIR/GAS RATIO 1 IMPORTANT: The appliance is set at the factory and adjustment to the CO2 settings (air/gas ratio) is only required where the appliance has been stripped down and assembled or if the fan, burner or gas valve are replaced or the appliance has been converted to a different gas type. A The air/gas ratio may only be adjusted on the basis of a CO2 measurement at maximum and minimum heat output using an electronic tester.
