OPERATING  INSTRUCTIONS

REDUCED  BURNING

For reduced burning the fire door must be closed.

When burning wood in areas that are not smoke controlled, load 
some large logs on the fire and allow to burn for half an hour before 
closing the air control (this will help to reduce tar deposits in the 
chimney). Some experimentation may be necessary to find the 
setting most suitable for the type of fuel being used and the draw on 
the chimney.

To revive the fire, empty the ashpan (if burning fuel other than 
wood), riddle the fire, and open the air control to maximum. When 
the fire is burning well load on more fuel as necessary and adjust the 
air control to the desired setting.

CLEANING AND MAINTENANCE

Cleaning

The stove is finished with a high temperature paint which will 
withstand the temperatures encountered in normal use. This may be 
cleaned with a damp lint-free cloth when the stove is cold. Should re-
painting become necessary, high temperature paints are available 
from your supplier or from stove shops.

Cleaning the Glass

Most deposits on the glass may be burnt off simply by running the 
fire at a fast rate for a few minutes. If it becomes necessary to clean 
the glass then open the door and allow it to cool. Clean the glass 
using a damp cloth and then wiping over with a dry cloth. Any 
stubborn deposits on the glass may be removed with a proprietary 
stove glass cleaner or ceramic hob cleaner. Do not use abrasive 
cleaners or pads as these can scratch the surface which will weaken 
the glass and cause premature failure.

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 air control should be left fully open and the fire door left ajar. It 
is also advisable to sweep the chimney and clean out the fire. 
Spraying the inside of the door and firebox with a light oil, such as 
W D40, will also help to keep all internal parts working well. After 
long periods where the fire has been out of use, the chimney and 
appliance flueways should be cleaned before lighting.  

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.

When burning authorised smokeless fuel follow the same lighting 
process as shown in figures 4-7  but use small kindling at first and 
then 1.9kg of heavier section (25mm square section) wood to give a 
good firebed.

Once the heavier section wood has established flame, add the 
mineral fuel, shut the door and pull the slider fully out. Push the 
slider in to desired setting once the fire is established in the coal.

REFUELLING

Keep the firebox well filled but do not allow fuel to spill over the top 
of the fuel retainer.

Logs should be evenly distributed, filling the firebed to give the most 
pleasing flame pattern. The air control must be fully opened after 
refuelling until the flames are established above the fire. It is best to 
refuel on to a hot fire bed of ash. If at this point the fire starts to die, 
the door must be cracked open until the fire is revived. If the fire has 
started to die down before refuelling, then more kindling wood must 
be added, the air control opened fully and the door cracked open to 
re-establish the firebed 

before

 adding fresh fuel. This will avoid 

excessive smoke emission.

Care should be taken, especially when burning wood, that fuel does 
not project over the fuel retainer or damage to the glass may be 
caused when the door is closed. It can also cause blackening of the 
glass. Maximum filling height is such that logs cannot fall from the fire 
when the door is opened. In smoke control areas do not fill the 
stove above the level of the air holes in the back bricks, as 
overloading can cause excess smoke. Liquid fuels are not to be used 
on this appliance.

When relighting the stove, leave the ash on the base if burning 
wood, unless it is becoming too deep, in which case some of it may 
be removed. If burning solid fuel, clear the grate and empty the 
ashpan before relighting.

ASH CLEARANCE

The ashpan should be emptied regularly before it becomes too full. 
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. The ashpan is handled using the tool provided. Care 
should be taken to ensure that ash is cool before emptying it into 
plastic liners or bins.

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, directly from Charnwood.
