4. stove when lighting e Keeping the Air control fully open until the fire is nicely established e Using only dry fuel e Severe stains can be removed when the glass is cold using special stove glass cleaning liquid available from solid fuel stove outlets NOTE After a period of use slight crazing may appear on the window This is not a fault It will not affect performance or increase the risk of breakage PROBLEMS Problems like those listed here are not normally caused by this appliance They are due to some difficulty with the fireplace chimney or fuels so check back through this leaflet carefully POOR HEAT OUTPUT This fire is sufficient to heat rooms up to about 160m 5650 cu ft depending on the type of fuel used and the building construction To heat a room larger than this may require an excessive fuel consumption Use only recommended fuels in the correct sizes Check main flue check stove flueways check air intake check grate bars check space below grate ensure ash is reasonably clear and not touching the grate DIFFICULTY IN BURNING FOR EXTENDED PERIODS Ifall the fuel has burned away this is probably because too much air has been reaching it There are several possible causes 1 The doors may not have been closed properly 2 The chimney draught was too high this can be a problem with any fire and usually happens when it is very windy 3 The air slide was not adjusted correctly 4 Not enough fuel was put on the
5. 5 BEND WITH CLEANING DOOR lt 458 gt t AFTERBURN AIR INTAKE The complete flue should be smooth internally without any voids in which gases can swirl or be cooled down nor any ledges on which soot may accumulate It must be possible to clean the entire length of flue In some installations it may be necessary to fit a cleaning door in the chimney If from experience it is decided there is excessive draw in the chimney and a draught stabilizer is fitted to the flue pipe or chimney in the same room as the appliance the permanent air opening should be increased by 300mm for each kW of rated output With the chimney warm a draw of 0 15 to 0 3 mbar is recommended For expert advice on Chimneys and Flues see page 1 INSTALLER S DUTIES Check that all parts are correctly fitted visibly check that seals between components firebricks etc are in place Light the fire see operating instructions Check that the flue functions correctly and all products of combustion are vented to the atmosphere through the chimney terminal Demonstrate use of the appliance and accessories to the user and hand over the instructions Offer to supply everything necessary for proper operation Fuel fuel store fuel hod ash carrier etc Remind the householder of the need for regular chimney sweeping and draw their attention to the Warnings in this document A 22160 10 9 98 YORKSHIRE DRY STOVE OPERATING INSTRUCTIONS PLE
