Firebelly FB2 stoves Attractive, efficient, economical and fully controllable... ...what more could you ask for? Firebelly FB1 A guide to stoves The benefits of stoves Providing an efficient, independent and guaranteed means of heating your home, a stove not only looks attractive but is a fully controllable appliance. Boiler stoves can provide an efficient and economical method of heating your home; providing you with hot water throughout the day. With an efficiency level of 65-80%, compared to an open fire efficiency level of 25-30%, a multifuel stove is a low cost alternative to burning oil or gas. For all of your heating needs, Mole Country Stores offers everything you need in one place. Wood and Solid Fuels Stove types When choosing the right stove for you, there are three types to consider: Wood burning stoves burn only seasoned wood or approved wood products; multifuel stoves burn approved solid smokeless fuel or seasoned wood and in most cases have a riddling grate. Boiler stoves can be either wood or mulitfuel and are designed to heat both the room and the boiler, which in turn can provide domestic hot water and water to run a central heating system. Fuels types When burning solid fuel: • Burn only fuels approved by your stove manufacturer. • Do not burn house coal or products containing petroleum coke as this will damage the stove and components. • A cast iron grate is recommended as solid fuel requires air from below to burn. When burning wood: • Wood should be well seasoned hardwood, with a moisture content ideally below 25%, stored in a dry, well ventilated environment (seasoned wood is wood that has been cut, split and stored for a recommended minimum period of 18 months allowing the moisture to evaporate). • Unseasoned wood will give poor heat output, tar your chimney and turn your stove glass black. • Kiln dried logs provide a clean burn with a much higher heat output than seasoned logs. • Hardwood is much denser than softwood so burns for longer. You will need almost twice as much volume of softwood to produce the same heat as hardwood. • Ideal types of wood to burn are: Oak, Beech, Birch and Ash. What not to burn: • Domestic rubbish – burning this in any stove will cause harm to the components and chimney, invalidating the manufacturers warranty. Full information regarding the most suitable fuels for our range of stoves is covered in your stove product manual. The carbon neutral option: wood releases the same amount of CO2 when burnt as if it were allowed to decompose naturally Hunter Herald 5 Slimline Choosing your Stove What size heat output is required? The most important factor is to choose a stove that gives out the correct heat so you are not too hot or too cold. Measure your room (length x width x height) in metres and divide by 14. Example - an average room of 4.8m x 4.8m x 2.6m = 59.9 divided by 14 = 4.3 kw average output required. Remember this is an average room. The number of doors and windows in the room and other factors such as stairs leading off the room, may increase the heating requirements. Similarly a well insulated house may reduce the heating requirements. Aura ll • Hearths should be made of solid, non combustible material at least 125mm thick. • For a stove installed into a recess, the hearth must extend 150mm to the sides of the stove and 300mm in front. • A free standing stove that has an under stove temperature of less than 100ºC, and has been tested by an approved body, may stand on a 12mm (minimum) non combustible hearth. The stove must have a clear surrounding hearth area of 150mm to the rear and sides of the appliance, plus 300mm in front of the hearth. Firebelly FB1 Installing a stove All stoves should be installed by a HETAS* approved installer. Alternatively, a building control officer can carry out an inspection. Upon satisfactory inspection, either parties will issue a certificate to confirm that the installation is correct. The manufacturer’s warranty may be invalid if no certificate of installation is available. For exact requirements, refer to Document J in the Building Regulations. Clearance requirements for fitting a stove vary between different manufacturers. Reduced clearance may result in reduced convectional heat into the room. Hearths The hearth that the stove sits on is a slab of non combustible material that extends around the stove to protect the floor, carpet etc from the heat and any burning material that may fall from the stove. • The edge of the hearth must be at a different level from the surrounding floor to define a safe perimeter. Connecting a stove to a chimney There is a distinct difference between a chimney and a flue. A chimney is the permanent structural part of the building, usually of brick construction. The flue refers to the inner passage which carries the exhaust gases through the chimney. The stove is connected to the chimney or flue with a short length of vitreous enamel or stainless steel flue pipe, connecting onto a flue system or liner. The minimum flue height should be 4.5m. Connecting a flue pipe (single skin) Vitreous enamelled steel flue pipe is used to connect a stove to a chimney or flue system. This: • Is designed for interior use up to 1.8m from the appliance. • Must be a minimum of three times its diameter from combustible materials, or one and a half times its diameter if protected with fireboard. • Must not run for more than 150mm from the rear of the stove (when running from the rear of a stove, a 90 degree sweepable tee piece is required). * See Useful Contacts page The minimum required diameter for a wood burning or a multifuel stove is a class 16 inch / 150mm liner. A 5 inch / 127mm liner is only suitable for a Defra exempt stove installed in a UK smoke control zone. • Access to the register plate must be provided for cleaning. • Bends and tee pieces may be required. Flexible flue liner (class 1): Constructed out of stainless steel, the lining is made of two thin layers, an inner and outer layer sandwiched together. This is often 316 grade. • Fast and efficient method of relining a chimney. • This would apply particularly to those installed before 1960. Useful points: • When going through an external wall, the angle must be no greater than 45 degrees. • If you do not have a chimney, you will need to build a traditional masonry lined chimney or the alternative would be a twin walled stainless steel flue system similar to Nova. • If the chimney is built pre 1960 it will probably need to be lined with a Class 1 flexible liner to suit the intended appliance, as oversized flues can be unsafe. The chimney can be back filled with insulator - either Leca, Vermiculite or Rocklap - to improve heat retention and stove efficiency. • Chimneys without bends perform better and are easier to clean and maintain. • Ventilation - appliances rated above 5kW require additional room ventilation. Rain cowl • Connects via a flexible pipe adaptor to a single skinned flue pipe. Chimney pot Mortar flaunching around pot • Must be installed correctly and fixed into the chimney. Top closing plate • Must have a rain cowl on the top. Top fixing clamp Twin walled flue system - suitable for wood, multifuel, gas and oil: Register plate • Can be used where there is no chimney. Flex pipe adaptor • The twin wall has to be a minimum of 50mm away from combustible materials. Single skin flue pipe running from the stove to the flex pipe adaptor • Two types are available: Nova for wood and multifuel systems, SMZ for gas and oil systems. Stove • The twin wall should be specified by a heating engineer. • Must have a rain cap on the top. Hearth Castech Firemaster 7 Maintenance and Care Chimney sweeping A chimney should be swept up to four times a year when burning wood or twice a year when burning solid fuel, preferably by a NACS* or NACE* qualified engineer, who will provide a certificate upon completion covering the visual condition of the flue in compliance with Building Regulations Document J. A poorly maintained flue liner may cause a chimney fire. Tar in a flue will burn vigorously and is very hard to extinguish. It can burn at over 10000C causing substantial damage and possibly a house fire. * See Useful Contacts page Stove & Fireside Accessories Log baskets Coal hods Coal buckets Fire grates Companion sets Ash carriers Hearth tidy sets Stove gloves Fireguards Fire cement Match holder and matches Stove rope Stove and grate polish Essential accessories to make fires and stoves safe and easy to operate.

By enclosing and controlling the burning process, up to 80% of the heat is retained and radiated into the room. What is a pre-heated airwash? An airwash allows a curtain of air to pass down inside the door, keeping the glass clean. What is meant by clean burning, secondary air and tertiary air? Clean burning is the term to describe the combustion process within the stove. This ensures that the gases and particulates are ignited in the firebox to offer complete combustion of all materials. This is achieved by injecting air above the fire bed – hence the term clean burning. Some stoves have a secondary air and even a tertiary air inlet above the firebed to improve combustion efficiency and clean burning. Can I burn my multifuel stove overnight? Most multifuel stoves are capable of burning for long periods, including overnight. Choose the right fuel and follow the instructions in your stove manual to achieve this and you will keep your home warm and cosy on long, dark, cold winter nights. Some very small stoves may struggle due to the size of the firebox. What is the difference between a wood stove and a multifuel stove? Generally a wood stove has no grate and therefore the wood fire is lit on a bed of ash on the stove base. With a multifuel stove you will have a grate as the air will need to come under the fire bed in order for the solid fuel to burn. Modern multifuel stoves are equally suited to burning wood and solid fuel. What are the differences between a steel and cast iron stove? Cast iron is the traditional choice for stove manufacturers but modern manufacturing methods mean that steel stoves are just as good. A cast iron stove will take longer to heat up and will radiate its heat longer after the fire dies down. Whereas a steel stove will heat up more quickly and will cool down more quickly after the fire dies down. Can I heat hot water and radiators with my stove? A number of stoves offer the option of an add in boiler which will allow you to heat a hot water tank and, in larger stoves, a towel rail or small radiator. If you want to run a complete central heating system there are dedicated boiler stoves capable of this. Be sure to ask a heating engineer to calculate the required BTU output for your heating needs in order that the appropriate boiler model can be chosen to suit your installation. See Boiler Stoves page.

Hunter Herald 14 Boiler Stoves Heating your home with a boiler stove Boiler output ranging from approx 12,000BTU – 54,000BTU If you are looking to use the heat generated by your stove to provide you with hot water and central heating with the addition of a boiler, you would need either an integrated boiler or a clip in boiler. Integrated boilers: Integrated boilers are more commonly known as wraparound boilers. They provide a much higher BTU output (British Thermal Unit - the amount of energy needed to heat one pound of water by one degree Fahrenheit) than a clip in boiler. As their name suggests, they are fitted into the stove and provide hot water for the home as well as your central heating. As the boiler is integrated into the stove, it cannot be replaced separately from the stove. Clip in boilers: Clip in boilers can be bought with the stove at the time of purchase or they can be bought after the purchase and retro fitted. This means that where there is a clip in boiler available for a specific model of stove, then a dry stove can be developed into a boiler stove and provide hot water, and in some cases central heating, to the home. As clip in boilers tend to provide a lower BTU output than an integrated boiler, they will only be able to service a small number of radiators. Please note, it is extremely important that your heating engineer or plumber calculates the required BTU output for your heating system before you decide on the boiler or boiler stove that best suits your needs. Top Tips for Stoves Installation • Always use a HETAS* qualified installer. Fuel • Use well seasoned or kiln dried wood. • Use approved solid fuels only. Always check manufacturers’ instruction handbook for guidance. How to light a fire • For solid fuel fires, ensure ash from previous fire has been removed. • For wood fires, a small layer of ash should be left on the grate of the fire box bed. • Open the bottom air vents in your stove. • Place a firelighter or scrunched up balls of paper (min 6 sheets) in the centre of the firebox (fire lighting material). • Place kindling (min 6 small pieces of dry, preferably soft, wood) on top of the fire lighting material. • Now lay some larger pieces of dry wood (no larger than 40mm square) on top. • Light the fire lighting material and close the stove door (or leave slightly ajar according to stove manufacturers’ recommendations). • Once the fire has caught, add larger pieces of wood or solid fuel to the fire and close the fire doors. • Adjustments to the stove vents will normally be required depending on the type of fuel being burnt and the draught up the chimney. If the fire burns too fast (uncontrollably) This could be due to: • An excessive air supply; check all vents and seals. • Door seals may require replacing. • Excessive chimney draw, in which case a chimney flue damper may be required. • The vents require closing. • The fire doors have been left open. • The throat plate is incorrectly fitted. If the fire burns too slowly This could be due to: • A poor chimney draught. • Wet or damp fuel. • Too much fuel in the firebox. • The air vents are closed. • Insufficient air supply in the room. If the stove is smoking This could be due to: • An insufficient flue draught. • An insufficient flue temperature. • Too much fuel in the firebox. • Wet or damp fuel. If the glass is blackened This could be due to: • Wet or damp fuel. • Under firing the stove. • Air vents being closed. Hot controls In normal operation the controls can get hot. Always use a stove glove.
