TROUBLE SHOOTING
RE-FUELLING WHEN BURNING WOOD
Adding fuel to your stove when you only have glowing embers,and the flames have died
down, is the cleanest way to refuel your stove.
1. Before refuelling, Pull open both the Primary and Secondary controls fully.
2. Unlatch the door to equalise the pressure inside the stove with that of the room.
3. Then, open the door gently.
4. If it is necessary, use a poker to create a level bed before adding a piece of wood, below the level of
the tertiary air ports (please check weight table page 7).
5. Now, close the door.
6. Once the flames are fully established, close Primary air fully and close Secondary air to the nominal posi�on
halfway in (50% air supply). For op�mum combus�on efficiency the tertiary air control should be pushed in.
Please regard these instruc�ons as guidelines because each installation will be slightly different. Experience will
determine the se�ngs that produce best results.
To prevent overhea�ng your appliance we recommend that you use a flue thermostat (placed on a non
insulated section of pipe directly above the collar of the stove).
The efficient opera�ng temperature range is between 180°C and 250°C
These stoves are not designed to run overnight or for long periods una�ended (see page 15)
Incomplete combustion may lead to a build-up of hard, shiny soot on the inside of your stove and glass. It is
generally the results of an insufficient air supply to the combustion chamber. If you find that this build-up is
occurring to your Mendip Stove, you should:
1. Increase the amount of secondary air used when running the stove, ensure the tertiary air control is
pushed in fully.
2. Check that the fuel you use is suitable and dry (less than 20% moisture content).
3. Check that your flue system (chimney) is producing sufficient draught.
It is important to check the dra� conditions before lighting your stove. This may be done, for instance, by
crumpling a piece of newspaper, placing it in the combustion chamber and lighting it. The dra� conditions are
good if the smoke is drawn away through the chimney.
1. Fire Will Not Burn - check
a) the air inlet is not obstructed in any way,
b) that chimney and flue ways 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 fi�ed in the same room
as the fire.
2. Fire Blazing Out Of Control - check
a) the doors are �ghtly closed,
b) the air controls are turned down to the minimum se�ng,
c) the flue damper is closed (if fi�ed),
d) a suitable fuel is being used,
e) the door seals are in good condition
f) the chimney dra� may be too strong
g) check ash pan seal and
h) check for ash below ash pan causing pan to seat
incorrectly and clean out.
INCOMPLETE COMBUSTION
3. Soot forms on the window
a) The firewood may be too wet
b) the intake of secondary air may be
insufficient
c) fire not hot enough
4. The stove fails to heat fully
a) The firewood may be too wet
b) the intake of secondary air may be
insufficient
5. Smoke or odour
a) weak chimney dra�
b) check for blockages in the flue pipe/chimney
c) check the height of the chimney rela�ve to
the surroundings
6. Soot in the chimney
a) The firewood may be too wet
b) intake of secondary air may be insufficient
