Charnwood SLX20 installation instructions Chimney Sweeping, Trouble Shooting

When not in use

If the fire is going to be out of use for a long period, (for instance in the summer,) then to prevent condensation, and hence corrosion, the thermostat should be left at the maximum setting and the main doors left ajar. It is also advisable to sweep the chimney and clean out the fire. Spraying the inside of the doors and firebox with a light oil, such as WD40, will also help to keep all internal parts working well.

Door Seals

For the fire to operate correctly it is important that the door seals are in good condition. Check that they do not become worn or frayed and replace them when necessary.

Servicing

It is recommended that the fire is serviced once a year to keep it in first class working order. After cleaning out the firebox thoroughly, check that all internal parts are in good working order, replacing any parts that are beginning to show signs of wear. Check that the door seals are in good condition and that the doors seal correctly. Check the operation of the thermostat, both when cold and hot. A servicing guide, TIS 48. is available on request.

CHIMNEY SWEEPING

The chimney should be swept at least twice a year. In most installations it will be possible to sweep the chimney through the appliance.

First remove the front firebars and the throat plate. Then sweep the chimney ensuring that soot is removed from all horizontal surfaces after sweeping.

In situations where it is not possible to sweep through the appliance the installer will have provided alternative means, such as a soot door. After sweeping the chimney the appliance flue outlet and the flue pipe connecting the appliance must be cleaned with a flue brush.

After cleaning any soot from within the fire, replace the throat plate and the front firebars.

Different types of sweep’s brushes are available to suit different flueways. For standard brick chimneys a wire centre sweep’s brush fitted with a guide wheel is recommended. For prefabricated insulated chimneys the manufacturers instructions with regard to sweeping should be consulted.

TROUBLE SHOOTING

Fire Will Not Burn.

Check that:

a)the air inlet is not obstructed in any way,

b)chimneys and flueways are clear,

c)a suitable fuel is being used,

d)there is an adequate air supply into the room,

e)an extractor fan is not fitted in the same room as the fire.

Fire Blazing Out Of Control.

Check that:

a) the doors are tightly closed,

b)the thermostat knob is turned down to the minimum setting and the airwash is closed,

c)the air inlet damper is closed (at the bottom left of the appliance, see Fig. 1.) and that it is not prevented from closing completely by a piece of ash,

d)a suitable fuel is being used,

e)the door seals are in good condition.

Over-Firing

If the fire is over- firing it will cause premature failure of the internal fire parts. Overfiring is occurring when any internal parts of the fire begin to glow red. To prevent over-firing ensure that:

a)the door seals are kept in good condition, and that the doors are sealing correctly,

b)the thermostat on the fire is working correctly,

c)a suitable fuel is being used.

Fume Emission

Warning Note: Properly installed and operated this appliance will not emit fumes. Occasional fume from de- ashing and re-fueling may occur. Persistent fume emission is potentially dangerous and must not be tolerated. If fume emission does persist then take the following immediate actions should be taken:

a)Open the doors and windows to ventilate the room.

b)Let the fire out and safely dispose of fuel from the appliance.

c)Check for flue or chimney blockage, and clean if required.

d)Do not attempt to relight fire until cause of fume has been identified, if necessary seek professional advise.

The most common cause of fume emission is flueway or chimney blockage. For you own safety these must be kept clean.

Freezing

If a boiler is fitted do not light the fire if there is any possibility that any parts of the system may be frozen.

Chimney fires

If the chimney is thoroughly and regularly swept, chimney fires should not occur. However, if a chimney fire does occur then turn the control knob to the minimum setting (see Fig. 1), and tightly close the doors of the appliance. This should cause the chimney fire to go out in which case the control should be kept at the minimum setting until the fire in the appliance has gone out. The chimney and flueways should then be cleaned. If the chimney fire does not go out when the above action is taken then the fire brigade should be called immediately.

After a chimney fire the chimney should be carefully examined for any damage. Expert advise should be sought if necessary.

Door Glass Backs Up

Differences in chimney draughts mean that the best setting of the air controls will vary for different installations. A certain amount of experimentation may be required, however the following points should be noted and with a little care should enable the glass to be kept clean in most situations:

a) The airwash relies on a supply of heated air to keep the
