Burning wood: 5.1 Do not refuel when a large amount of flames are present in the firebox as this could cause smoke or flames to spill into the room. This appliance gives out its heat in two ways: —Directly into the room in which it is fitted through convection and radiation. Close the doors immediately after refuelling.
USER INSTRUCTIONS 5.8 De-ash the firebed before re-fuelling (see User Instructions, Section 7). 6. Burning tips Open the Primary Air Control fully to establish a glowing bed before adding new fuel. 6.1 Burn new fuel at a high temperature (see Diagram 7) for a few minutes before adjusting the Primary Air Control to the desired setting. Refuel little and often for clean, efficient burning. 5.9 Fuel Quality (Wood) Use wood with a moisture content of less than 20%.
USER INSTRUCTIONS Draught is caused by the rising hot air in the chimney when the appliance is lit. 7. ASH REMOVAL Symptoms of poor performance related to flue draught include: —Excessive fuel consumption (high flue draught). —Poor burning control, overheating (high flue draught). —Wind noise from air controls (high flue draught). —Difficulty getting a fire going and keeping it burning well (low flue draught). —Low heat output (low flue draught). —Smoke entering room when doors opened (low flue draught).
USER INSTRUCTIONS —Fit the plug supplied into the hole where the riddling mechanism is normally located and secure with bolt and clamp (also supplied, see Diagram 15). 8. Wood burning tray 8.1 In order to burn wood continuously in this appliance a Wood Burning Tray should be fitted (see Diagram 12). 15 12 Clamp Plug Bolt Front edge PR8865 PR8862 8.2 Remove the multi-fuel grate from the appliance (see Installation Instructions, Section 5). 8.
USER INSTRUCTIONS Check that the door shuts properly and creates an effective seal. Leaking door seals prevent the appliance working properly. 11. Chimney fire 11.1 If a chimney fire occurs: Do not use aerosol sprays near an operating appliance. —Shut all air controls immediately. —Evacuate the building. 13.

USER INSTRUCTIONS 130°C - 250°C (270°F - 480°F). Failing to close down the Primary Air Control once the appliance has heated up to this range may cause the appliance to exceed the ideal temperature range and to over-fire. Over-firing can cause permanent damage to the appliance and invalidates your warranty. Burn with the Airwash Control fully open for approximately 20 minutes to cure this. 15.
USER INSTRUCTIONS 17.5 All or some of the radiators do not get hot Open up the airwash to make a hotter fire Burning wood Wood is burning too slowly If fitted set the thermostat to a higher setting Burn dryer wood Burn better quality wood Reduce ashbed to 1" thick Burning Solid Mineral fuels Fuel is burning too slowly Open up the primary air to make a hotter fire. If fitted, set the thermostat to a higher setting The fire needs riddling to remove ash. De-ash the fire Empty the ash pan.
