Charnwood LA10, Operating & Installation Instructions Manual

a) Wet or unseasoned wood, or logs overhanging the front fence will 
cause the glass to blacken.

b) The airwash relies on a supply of heated air to keep the glass clean, 
therefore, when lighting the stove allow the firebed to become well 
established before closing the front air control slider. This may also be 
necessary when re-fuelling the stove.

c) When re-fuelling keep the fuel as far back from the front fence as 
possible, do not try to fit too much fuel into the firebox.

d) Never completely close the airwash control - as a guide it should 
be at least a quarter open.

e) The front air control slider  may be kept slightly open to assist in 
keeping the glass clean.

It is always more difficult to keep the glass clean when running the 
stove very slowly for long periods.

If blackening of the glass still occurs check that all flue connections 
and the blanking plate are well sealed. It is also important that the 
chimney draw is sufficient and that it is not affected by down-
draught.. When the chimney is warm a draught reading of at least 
2.5 mm (0.10 inches)  water gauge (25Pa) should be obtained.

Some blackening of the glass may occur below the level of the fuel 
retainer. This will not obscure the view of the fire or affect its 
performance.

Fume Emission

Warning Note:

Properly installed, operated and maintained this appliance will 

not emit fumes into the room. Occasional fumes from de-ashing 

and re-fuelling may occur. Persistent fume emission is potentially 

dangerous and must not be tolerated. If fume emission does 

persist, then the following immediate actions should be taken:

a) Open doors and windows to ventilate the room and then leave 

the premises.. 

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

appliance.

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

d) Do not attempt to re-light the fire until cause of fuming has 

been identified, if necessary seek professional advice.

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

CHIMNEY SWEEPING

TROUBLE SHOOTING

Where the chimney previously served an open fire, it is possible that 
the higher flue gas temperature from a stove may loosen soot 
deposits with the consequent risk of flue blockage. It is therefore 
recommended that the chimney be swept a second time within a 
month of regular use after installation. 

The chimney should be swept at least twice a year. Where the top 
outlet or vertical rear flue connector is used it will generally be 
possible to sweep the chimney through the appliance.

First remove the fuel retainer 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 stove to the chimney must be cleaned with a flue 
brush.

After clearing any soot from within the stove, replace the throat plate 
(see Fig. 3.) and the fuel retainer.

Fire Will Not Burn.

Check that: 
a) the air inlet is not obstructed in any way, 
b) chimneys and flueways are clear, 
c) that a suitable fuel is being used, 
d) that there is an adequate air supply into the room, 
e) that an extractor fan is not fitted in the same room as the stove.
f) there is sufficient draw in the chimney. Once the chimney is warm a 
draught reading of at least 2.5 mm (0.10 inches) water gauge (25Pa) 
should be obtained.

Door Glass Blacks Up

Differences in chimney draughts mean that the best settings 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:

Different types of sweep’s brushes are available to suit different 
flueways. For prefabricated insulated chimneys the manufacturers 
instructions with regard to sweeping should be consulted.
