Charnwood DX20i MkII ASH Clearance, Refuelling, Overnight Burning, Riddling

For safety reasons, if the fire is to be left unattended with the doors open then use a spark guard which complies with BS 3248.

ASH CLEARANCE

The ashpan must be emptied regularly before it becomes too full. The most convenient time to remove the ash is just before riddling the fire since the ash will then be at it’s coolest. Use the tool provided to remove the ashpan.

Never allow the ash to accumulate in the ashpan so that it comes in contact with the underside of the grate as this will seriously damage the grate bars.

Ensure that the air inlet damper is not prevented from closing by spilled fuel or ash.

Care should be taken to ensure that ash is cool before emptying it into plastic liners or bins.

using solid fuel do not go beyond the 45° position as this can cause the grate to jam.

If jamming does occur then the fire should be allowed to burn for approximately half an hour before riddling the grate again as described above.

Too much riddling can result in emptying unburnt fuel into the ashpan and should therefore be avoided. Clinker should regularly be removed from the firebed.

REFUELLING

Keep the firebox well filled (the fuel may be sloped up from the front firebars), but do not allow fuel to spill over the top of the front fire bars. Take care, especially when burning wood, that fuel does not project over the front fire bars or damage to the glass may be caused when the doors are closed.

OVERNIGHT

BURNING

Empty the ashpan, if necessary, and then riddle the fire. If the fire is very low then it may be necessary to add a little fuel and turn the thermostat control up for a brief period until the fire is burning well before filling with fuel. When burning wood use large logs overnight as they will burn more slowly than small ones.

To make ash removal easier there is a special Charnwood ash carrier available. This may be purchased from your supplier or, in case of difficulty, from ourselves.

RIDDLING

When burning solid fuels riddling twice a day is usually sufficient. When burning wood or peat, ash should be allowed to build up and generally riddling every other day will be sufficient.

Some experimentation may be necessary to find the setting most suitable for the particular fuel used and the draw on the chimney, but generally the thermostat should be turned down to the minimum setting and the airwash control nearly closed overnight.

For overnight burning the fire doors must be closed.

To revive the fire, empty the ashpan if necessary, riddle (when burning solid fuel), and turn the thermostat

The fire should be riddled with all doors shut. Place the tool on the knob and rotate between the horizontal and the 45° position several times as shown in Fig. 3.

When burning wood or peat do not riddle all the ash into the ashpan, keep a layer about 12 mm (1/2 inch) thick on the grate.

Caution: when riddling the grate

Fig. 3. Grate Operation

After riddling, the grate should be put back into the solid fuel or wood position as required (the tool should be horizontal for solid fuel or vertical for wood or peat).

control knob to maximum and open the airwash control. When the fire is burning well load on more fuel as necessary and set the thermostat and airwash controls to the desired setting.

When burning wood do not riddle but simply set the air controls to maximum until the fire picks up and then set them at the desired setting and refuel as necessary.
