UNPACKING & ASSEMBLY UNPACKING WARNING: DUE TO THE WEIGHT OF THE STOVE IT IS ADVISED THAT TWO PEOPLE PERFORM THE UNPACKING. Unpack the stove and remove packing materials. Open the door and remove the loose items from inside the stove. Before assembling, please check contents against the following list and advise your dealer immediately if any parts are missing. Refer also to parts list & diagram on pages 24 & 25.
1. Lay the stove down on a soft surface such as the packing materials from the crate. 2. Attach the legs using the studs, nuts and washers supplied as shown in Fig 1. Tighten the studs using the spanner. 3. Sit the stove upright and attach the flue adaptor as shown in Fig 2 using the screws supplied. Ensure the fireproof gasket is correctly seated in the base of the flue adaptor. 4. Install the blanking plate in the rear of the stove when the normal flue exit is required.
POSITIONING AND INSTALLATION REGULATORY COMPLIANCE In England and Wales, there are only two routes to legally install a domestic solid fuel or wood burning appliance. In other parts of the UK there are variations in legislation and processes. You can either: • Use a registered installer who can self certify that the work he does complies with the relevant Building Regulations; or • The consumer applies to their local authority building control department for a building notice, and pays the appropriate fee.
When the stove is positioned near a wall constructed of flammable material, the distances shown on Fig 4 must be adhered to. Alternatively, a heat shield may be used, mounted according to the position of the fireplace. A firewall must be at least 100mm thick and typically made of brick, or concrete/stone. MATERIAL CLEARANCES The stove must have a minimum clearance of 1200 mm to a combustible ceiling above.
Sizes of flues in chimneys are stipulated in Table 2 of the Building Regulations 2000 Approved Document “J” as follows: 1. Stoves under 20kW rated output which burn smokeless or low volatile fuel require a minimum flue size of 125mm diameter (or rectangular flues having the same cross-sectional area and a minimum dimension not less than 100mm for straight flues or 125mm for flues with bends or offsets. 2.
FIG 5 External flue pipes should be “twin wall”. These retain the heat, enabling it to rise and disperse from the chimney. As an alternative approach, the calculation procedure within BS EN 13384-1 (2005) can be used as the basis for deciding whether a chimney design will provide sufficient draught. If in doubt, consult the Building Regulations.
INSPECTION & CLEANING Check that the chimney is in good condition, dry and free from cracks and obstructions. The diameter of the chimney should not be less than 150mm and not more than 230mm. If any of these requirements are not met, the chimney should be lined by a suitable method. The chimney must be swept before connection to the stove.
. Stove Air Supplies Stove with flue draught stabiliser Permanently open vents as below: If design air permeability>5.0m3/(h.m2) then 300mm2/kW for first 5kW of appliance rated output 850mm2/kW for balance of appliance rated output If design air permeability<5.0m3/(h.m2) then 850 mm2/kW for balance of appliance rated output Stove with no flue draught stabiliser Permanently open vents as below: If design air permeability>5.0m3/(h.
FIG 6 A non-combustible register plate minimum 1.5 mm thick should be fitted to all installations between the flue and the building structure. It’s suitability and fit should be checked by a qualified stove installation engineer against the current Building Regulations App”J”.

CLEANING THE FLUE Access for cleaning the flue should be incorporated in the system other than through the appliance (e.g. a soot door or access through a register plate). Purpose-made soot doors and inspection lengths are available from the Clarke range. Ensure that the whole length of the flue can be reached from the soot door. FUME EMISSIONS To avoid chimney problems, your fire should not be burnt slowly for longer than 12 hours without a period of fast burning.
CARBON MONOXIDE ALARMS Due consideration should be given to the dangers of carbon monoxide poisoning following incomplete combustion of solid fuels in an enclosed space. Carbon monoxide detectors to BS EN 50291 are available for use in domestic premises and details are available in the official HETAS guide that can be viewed on their website at www.hetas.co.uk.
USING YOUR STOVE THE CONTROLS WARNING: THE TEMPERATURE REACHED BY THESE ITEMS DURING OPERATION MAY CAUSE AN INJURY TO AN END-USER. AS THESE ARE INTENDED TO BE ADJUSTED DURING OPERATION, IT IS RECOMMENDED THAT A PROTECTIVE MITT IS WORN WHEN HANDING THESE PARTS. The amount of heat emitted by the stove is regulated using the air control (A) built into the door and to a lesser extent, by the air wash vents at the top (B) and secondary control at the bottom (C) of the stove.
The control knob (D) near the side of the stove is for riddling the grate section, causing loose ash to fall into the ashpan. SUITABLE FUELS This stove can be used in smoke controlled zones to burn wood/logs will function with wood or coal, but in general all fuel should be dry and timber should be well seasoned so as to have a moisture content below 20%.
INITIAL SEASONING Follow installation, and before regular use, the stove must be seasoned to prevent cracking of the metal casting. This procedure should also be followed if the stove has not been used for prolonged periods (during the summer months for example) and is carried out as follows: CAUTION: THIS STOVE MUST BE SEASONED BEFORE USE. FAILURE TO CARRY OUT THIS IMPORTANT PROCEDURE WILL RESULT IN PERMANENT DAMAGE TO THE STOVE AND WILL VOID YOUR WARRANTY.
6. The burn rate can be reduced by partially closing the air control. FIRE-LIGHTING WITH WOOD 1. Open the air control. 2. Lay firelighters or rolled up newspapers on the grate with a reasonable quantity of dry kindling wood. Place 2 or 3 small logs on top. 3. Light the newspaper or firelighters using a long taper and close the door. 4. When the fire is burning strongly add further logs up to 10mm diameter. 5. When the stove is really hot, close the air control as required.
When disposing of ashes, ensure they have cooled and always place in a metal container. Be sure to remove the ash when the fire is at its lowest point, such as first thing in the morning. The Clarke Ash Can Filter is ideal for use in conjunction with the Clarke range of vacuum cleaners, for collecting hot ash and debris from stoves. MAINTENANCE CLEANING The inside of the stove may require regular cleaning, especially during periods of peak use, the frequency of this being indicated by experience.
FIRE ROPE Check the rope around the door and glass. If rope is becoming detached, replace with rope approved for this purpose. Inspect the fireproof door seal where fitted, to ensure there is an effective seal around the door and re-fix it if loose using stove rope adhesive. If in poor condition it should be replaced. GLASS PANELS Clean any glass panel when cool, avoiding abrasive substances which could scratch the glass and make subsequent cleaning more difficult.
The flue and chimney should be inspected for a build-up of deposits especially following prolonged periods without use. The entire chimney/flue should be swept frequently from top to bottom by a registered chimney sweep to remove any build-up of soot etc, the frequency being dependant upon the usage and the fuels being burnt. If the chimney is swept after a few weeks of regular use, the condition found will give an indication of the frequency of sweeping required.
TROUBLESHOOTING PROBLEM CAUSE SOLUTION Fire difficult to start. Wood green, too damp or poor quality. Use recommended fuel. Logs are too large. When lighting, use small, dry kindling. To maintain the fire use split logs. Air starvation Open air control. Insufficient draught. Check that flue is not obstructed, sweep flue if necessary. Fire goes out. Fire burns too quickly. Too much draught. Ensure the air control is closed. Install a draught stabiliser. Consult your dealer.
