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.
INSTALLATION 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.
INSTALLATION MULTIFUEL GRATE GRATE GRATE BAR REPLACEMENT 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. After extended use it may be necessary to replace some of the grate bars.
INSTALLATION FITTING THE FLUE OUTLET AND HOT PLATE The flue outlet spigot is found inside the appliance. It is removed by turning clockwise. Smear a very thin layer of fire cement on the faces of the flue outlet and the blanking plate. Fit the outlet to the appliance in the desired position. Lock into place by rotating anti-clockwise and tighten by tapping with a block of wood and mallet from the inside of the appliance. Similarly, fit the blanking plate to the unused opening.
INSTALLATION Due to the gradual introduction of European Chimney Standards chimneys will be specified according to their performance designation as defined in BS EN 1443 that covers the General Requirements for chimneys. The minimum performance designation required for use with solid fuel burning stoves is T450 N2 S D3. Precautions" section page 8 of these instructions.

INSTALLATION TYPICAL METAL INSULATED CHIMNEY SYSTEM TO BE INSTALLED TO THE CHIMNEY MANUFACTURERS INSTRUCTIONS IN COMPLIANCE WITH BUILDING REGULATIONS AND BS7566 PTS 1-4 PLAN VIEW OF REGISTER PLATE AND CLEARANCES FOR NON INSULATED FLUES A is minimum clearance for non-insulated flue = 1.
INSTALLATION INSTRUCTIONS ADD IN BOILERS Acorn 4 & 5 multifuel stoves offer the option of a slab boiler, which occupies the position of the rear firebox liner panels. Fitting: •Remove the fuel retainers, rear firebox liner panels and throat plate. •Knock out the blanking discs in the back plate corresponding to the terminals on the boiler.
INSTALLATION INSTRUCTIONS The expansion tank should have a capacity of at least 7 % of the system's water capacity. The cold water feed pipe should be at least 22mm diameter. There must not be any shut off valves in the circuit. Pipes should be run to avoid air locks. A spring safety valve should be fitted to the expansion pipe close to the boiler. It is often possible, and is good practice, to utilise the primary flow and return as part of the safety circuit. The ball valve should have a copper ball.
OPERATING INSTRUCTIONS multifuel grate position and for emptying the ash pan. (Fig. 10) Fig. 7 Fully Closed Fig. 8 Fully Open Even when all the slots are completely shut a "bleed" of secondary air will be maintained ensuring that inflammable gases are burnt off. Fig. 10 DISASSEMBLE AIRWASH The Aarrow air wash may be disassembled for cleaning or adjustment.
OPERATING INSTRUCTIONS •Refit the door and check to ensure it now sits square to the body; if not repeat above steps. FUEL TYPES Fig. 11b fitting new glass •Replace the two lower retaining clips and nuts. •Replace the upper airwash cover and nuts. Do not over-tighten the nuts as damage may occur to the glass (Fig.11c) Wood- Any type of wood is suitable provided it is well seasoned and has a moisture content below 20%.
OPERATING INSTRUCTIONS Do not use Homefire (six sided) and smaller sizes than Stovesse, e.g. Beans,Peas,Grains. Do not use petroleum based solid products such as Calco or Petrocoke. To do so will INVALIDATE the appliance guarantee. position and the fire doors are closed. •Set the air wash to one quarter open position. •Set the primary inlet to the fully open position •Light in the normal manner with paper and kindling, or use a fire lighter.
OPERATING INSTRUCTIONS In the morning DE - ASHING •Open the air control fully until embers begin to glow brightly and place pieces of fuel on the fire until it is well established. It is necessary to maintain an ash layer on the upper surface of the grate bars, in order to protect them so de-ashing should cease as soon as the first red embers drop into the ash pan. Further de-ashing will cause heat build-up under the grate, which will considerably shorten its life.
OPERATING INSTRUCTIONS CLEANING DOOR GLASS Important; Under some circumstances soot can quickly build up on the throat plate and adjacent areas. The throat plate should be removed and checked monthly, and any debris stripped off. Similarly, clean the upper surface of the firebox. The door glass should remain clear during normal daytime burning. However under certain conditions-such as burning at a low rate with damp wood, or overnight burning, the glass may become somewhat blackened.
