Air Supply if fitted Flue Collar 157mm dia wt Welcome to more than one hundred and fifty years of Esse You join the illustrious tribe of Esse fire keepers from Florence Nightingale Captain Scott Mrs Beeton Auguste Escoffier Queen Victoria and most of the Royal Families of Europe to Fred Dibnah and Hugh Fearnley Whittingstall THIS APPLIANCE BECOMES EXTREMELY HOT AND CAN PRODUCE POISONOUS GASES A fire guard should be used if children or the infirm are present The installer is required to EXACTLY follow these instructions and to comply with all local national and applicable international standards LOCATION This appliance is 400mm to 460mm heavy a load distribution plate may be needed on weaker floors The appliance must be located on a flat hearth extending at least 225mm in front of the fire and of suitable material to protect the building from fire Combustible materials including fuels must be at least 225mm away from the room parts of the appliance This stove can fit into fireplace openings of 400 to 460mm wide and 550 to 590mm high If the Outside air kit is used fireplaces must be prepared with an extra opening to the lower right of the face as shown YOUR CHIMNEY makes your fire work It stores surplus heat from the fire which makes the gas inside its hollow flue lighter so that it rises pulling fresh air through the fuel and making it burn The Greenswitch is for connection
3. Dismantle the boiler If the unit is supplied assembled lift off the top of the front and carefully pull the cylindrical brass thermostat sensor from its holder Unfasten the 4 bolts shown lift the front unit up slightly and carefully part the two units Take very great care not to damage the soft seal 2 Prepare the setting fit and test the boiler Place the boiler rear unit on a hearth which will extending at least 250mm in front of the assembled fire noting that the final surface of the fireplace will be just behind the two flanges arrowed In this example the air supply kit has been fixed to the side of the boiler with adhesive tape prior to being cemented in Complete the piping circuit fill and inspect for leaks as you wont be able to repair leaks later 3 Brick up and form the flueway Build up a masonry wall around the boiler forming a smooth connection to the flue with no ledges where debris could collect Fill any space with mortar and rubble Shown part completed 4 Fit fireplace surround Slot a ready made fireplace surround in place or build one up using brick stone or other masonry or metal materials Extra fixing if needed is through the screw holes shown 5 Refit front and check thermostat Bolt the door front unit back in place taking great care that the parts seal Reassemble the interior fittings and check that the door closes and seals properly Push the
4. call the fire brigade Prevent fires by using very dry fuel and having your chimney swept regularly DIRTY WINDOW Is fuel absolutely dry The window will become dirty when the fire operates at low levels for a long time but will usually self clean at higher burn rates MAINTENANCE EVERY MONTH When the fire is cold use the operating tool to pull forward and clean the throat plate Check that the door seals are sound ANNUALLY or more often if smoky fuels are used sweep the entire length of the flue from firebox to chimney outlet REPLACEABLE PARTS Internal parts will last far longer if special care is taken to empty ash from mineral fuels regularly to clean the throat plate and to use completely dry fuel The GreenSwitch has been extensively tested for safety please don t try to modify it and always make sure to get genuine spare parts Your GreenSwitch is guaranteed excluding wearable parts for one year from the date of purchase in addition to your statutory rights 4 SE REPLACEABLE PARTS The Esse 300 and 350 Greenswitch Boiler the Furnesse Chroma and Virtine door designs are registered at the UK Patent Office and protected by Copyright and UK Design Right Glyn Hughes and the Ouzledale Foundry Esse Engineering 1994 2009 The Esse 350 Greenswitch central heating boiler is UK Patent Applied For Esse appliances are forever being developed and improved your applianc
