Acorn Multifuel Stoves5 INTRODUCTION SAFETY A fireguard conforming to BS 8423: 2002 should be used in the presence of children and old/or infirm people. If the appliance is used with the fire door open, a spark guard conforming to BS 3248 should be fitted. Do not use aerosol sprays or any other flame near the appliance under fire. Do not fit an extractor fan in the same room as the appliance. Fire cement is caustic, hand and eye protection should always be worn, prolonged contact with the skin should be avoided. Aarrow Fires Ltd will not be responsible for any consequential or incidental loss or injury however caused. Before continuing any further with the installation of this appliance please read the following guide to manual handling. • Always obtain assistance when lifting the appliance. • When lifting always keep your back straight. Bend your legs not your back. • Avoid twisting at the waist. It is better to reposition your feet. • Avoid upper body/top heavy bending. Do not lean forwards or sideways when handling the fire. • Always grip with the palms of your hands. Do not use fingertips for support. • Always keep the stove as close to the body as possible. This will minimise the cantilever action. • Use gloves to provide additional grip. THE PRINCIPLE OF THE FIRE Your Aarrow Fire is built to the highest standard of craftsmanship using the best materials and the most modern equipment available. It is a highly efficient and sophisticated piece of machinery and when properly installed and operated it should provide a lifetime of heating satisfaction.Safetyis the most important consideration when installing your fire. If not properly installed and operated a house fire may result. installation must comply with the Building Regulations and conform to all relevant fire safety standards. Aarrow Fires produce a variety of appliances ranging from units, which are traditional in style to stoves which are modern in appearance, all bristling with High Tech features. Model types include simple room heaters, convectors, integral boiler models and inset units. Your Aarrow Fire is constructed from either single or twin wall steel strengthened where necessary. Cast iron is used where appropriate for decorative features. All fire doors are fitted with special high temperature ceramic glass panels through which the fire can be viewed. Multifuel stoves are fitted with a cast iron grate to give full multifuel facility and positive de-ashing. All models except integral boiler models are lined with firebricks or heat reflective panels which ensure complete combustion and provide a good heat store to even out fluctuations in burning. An internal throat plate produces turbulence to encourage secondary combustion and directs the flue gas around the whole upper firebox before allowing it to escape up the chimney. On multifuel appliances the primary air for burning enters the ash pit chamber beneath the grate, controlled by the air inlet mechanism. Aarrow Fires are also fitted with an air wash so called because it provides a curtain of high speed preheated air behind the glass to help keep it clean and to provide secondary air/over draught. The provision of two inlets on all multifuel stoves gives a wide range of primary air/secondary air, under draught/over draught combinations. The optimum settings will only be established by experience in firing the appliance, and will depend on type of fuel, the position of the appliance in the house, condition of chimney etc.

8Acorn Multifuel Stoves INSTALLATION GENERAL PRECAUTIONS Note - All installations must conform to the appropriate building regulations. The Building Regulations for England and Wales 2000 ref Approved Document J 2002 edition (issued by the DTLR). The Building Standards (Scotland) (Consolidation) Regulations. Detailed recommendations for installation of appliances, chimneys and flues are outlined in the current issue of the following British Standards:- BS6461, BS8303 and BS4543. Any Manufacturers Instructions must not be taken as overriding statutory requirements. During installation ensure that adequate precautions are taken to avoid unnecessary risk to yourself or any householder. In particular the danger from the caustic nature of the fire cement should be avoided by using these accepted methods: •Wear gloves when handling fire cement. •Wear goggles when chiselling or looking up chimneys. Make sure that Building Regulations are adhered to during installation along with any local by-laws. In the case of heating systems make sure that the pipe work is correctly bonded to ensure electrical earthing. HANDLING By the time you read this you will appreciate the weight of the appliance. The Safety and handling guidelines as set out on page 5 of this manual should be followed. To make movement easier internal fittings, grates, firebox liners, flue outlets, hot plate, throat plate, etc., can be removed. Care should be taken to make sure that the hinges are not damaged during installation. HEARTH The fire should be installed to stand on a constructional hearth of non-combustible materials not less than 125mm (5) thick conforming to Building Regulations. Dimensions of the hearth should project at least 300mm (12) forward of the front of the appliance and 150mm (6) at the sides. The surface of the hearth should be free of combustible materials. In most buildings with solid concrete floors the requirement will be met by the floor itself, but mark the perimeter of the hearth to ensure floor coverings are kept well away or use different levels to mark the hearth perimeter. COMBUSTIBLE MATERIALS A gap of at least 450mm (18) should be allowed between the appliance and any combustible materials including furnishings. Adjacent walls should be of suitable non-combustible construction, preferably brickwork. In large fireplaces take care that any supporting beam is protected by a 13mm (0.5) sheet of Masterboard/Supalux spaced 13mm (0.5) off the surface with strips of non-combustible material - not wood. Make sure that there is a gap between an uninsulated flue system and any combustible material. This gap must be at least 3 x the outside diameter of the flue pipe, or 1.5 x the flue diameter to non combustible surfaces. See the illustration on page 14. AIR FOR COMBUSTION There must always be a permanent means of providing air for combustion into the room in which the fire is installed. A permanent vent with a total free area of at least 550mm 2for every kW rated output above 5kw should be connected directly to the outside air or to an adjacent room which itself has a permanent vent of the same size direct to the outside air. The fitting of an extractor fan to either of these rooms is not recommended.
FIREBOX LINER PANELS The Acorn Multifuel stoves have reflective liners to the sides and back. The throat plate sits on top of the side and rear panels. These should come fitted to your fire, if however they are not proceed as follows to fit them. •Remove the front brace retainer. •Set the small liner into the back of the fire. •Insert side liner panels •Fit the throat plate with the single bend and two cut outs to the front facing up. The projecting lugs sit on top of the side liners. The long centre tab on the back edge rests on the rear liners. The shorter turn-down tabs against the vertical face. •Replace the front brace retainer. Note: Neither the rear firebox liners nor the side firebox liners are handed, both faces are suitable for direct contact with the fire. Fig. 1 Liners inserted in Acorn Fig. 2 Inserting throat plate Fig. 3 Liners, throat plate and grate in the Acorn.REMOVAL OF THE THROAT PLATE Blocked chimneys cause dangerous fumes to escape. Remove the throat plate at least monthly to clean. Keep chimney and flue ways clear. FITTING THE OPTIONAL FLOOR FIXING KIT Once the stove is in the correct position it is recommended that the fire is fixed to the floor for safety purposes: You will need a No. 2 pozi drive screw driver to carry out this operation. Place the brackets each side of the appliance. Fig. 4 Lining up the bracket Slide the small threaded hole underneath the gap (as shown above) and turn inside so the both holes match the pre-drilled one. Repeat for the other side. Fig. 5 Inserting and tightening the screws. When both are in place, tighten the screws until they are firmly inserted. Then proceed to drill your hearth and insert and anchor bolt or similar fixing (Not supplied in kit) and bolt down the brackets once the appliance is in place. For further instructions please consult the floor fixing instructions attached to the kit. Acorn Multifuel Stoves9 INSTALLATION
MULTIFUEL GRATE GRATE The grates in the Acorn Multifuel units comprise a series of reciprocating cast iron bars seated on a pivoted comb. All bars in the grate are identical, but every other bar is turned through 180 degrees, with the ends of the bars marked H sitting on the high sections of the comb, and the ends marked L sitting on the low sections. ASSEMBLING THE GRATE To assemble the grate, fit bars to low sections of the comb first, inserting end marked H into rear channel with groove on underside of bar located on upstand tab, and then lowering end marked L onto the low section of the comb. The upper bar is fitted in a similar manner, but with the end marked L inserted in the rear channel, and the end marked H seated on the high section of the comb. 10Acorn Multifuel Stoves INSTALLATION GRATE BAR REPLACEMENT After extended use it may be necessary to replace some of the grate bars. Periodic inspection of the bars is recommended and the removal of any nails or wire that may be present after burning wood. All the grate bars in each appliance are identical and can easily be lifted out after removal of the fuel retainers. Remove damaged grate bars and replace with casting of the same type, fitting as per instructions above. (Check Identification letters on the casting when reordering).
