(i.e. when Central heating is not in use).
The fire-box of this cooker can not be modified to
reduce the boiler output while cooking. Therefore if
cooking is carried out during the summer months then
adequate dissipation of the heat produced be allowed
for in your central heating circuit to ensure that the hot
water within the circuit does not boil.
SUMMER OPERATION
All fuels should be stored under cover and kept
as dry as possible prior to use. This appliance has
been tested using manufactured briquetted smoke-
less fuel (Ancit) for closed appliances, sized between
20g and 140g and wood logs. Other fuels are
commercially available and may give similar results.
Wood logs up to 380mm long are suitable. All fuels
should be stored under cover and kept as dry as
possible prior to use.
Do not use fuels with a Petro-coke ingredient as this
may cause the grate to overheat, causing damage.
Reduced outputs will result when fuels of lower
calorific values are used. Never use gasoline or
gasoline type lantern fuel, kerosene, charcoal lighter
fluid or similar liquids to start or freshen up a fire in
this heater. Keep all such liquid well away from the
heater at all times. Operate the stove only with the
fuelling door closed except for re-fuelling.
RECOMMENDED FUELS
OPERATION
Before lighting the fire move the flue damper position
to ‘by-pass’ this will allow flue gases to the chimney
unobstructed, when the fire is established the damper
position can be moved to cooker. See Fig.1
LIGHTING THE FIRE
Fully open the thermostat and set the flue damper to
by-pass, kindle with paper and sticks in the usual way
and ignite by using a taper or rolled wad of paper in-
serted into the ashpit. Under no circumstances should
any inflammable liquid i.e. petrol, paraffin etc. be used
to light the fire. When the fire is well established close
the direct damper fully and keep it closed. Add fuel to
the firebox as required and adjust the thermostat to
suit the current requirements. The cooker should not
be used as an incinerator.
When fuelling set the flue damper to by-pass as this
will help to eliminate smoking.
Afterwards be sure to
reset the flue damper to the required setting. Never
pack fuel tightly or fill the firebox to capacity. A lower
level fire is more effective particularly in regard to
water heating efficiency. The maximum fuel level is
up to the bottom of the firebox door and rising up-
wards at a 30
o
angle towards the back of the firebox.
If the appliance is run for extended periods on a low
fire, especially when burning wood or peat the fire can
cool down to such an extent that vapour in the flue
gases may condense. This will make the inside of the
flue damp so that the soot sticks to the flue and the
tarry mixture formed may drip down into the appli-
ance. It is always a good idea to run at a high rate

WARNING: If there is a possibility that a part of
the heating system may be frozen you should
not light the stove until you are confident that
the system is free of ice, has no leaks and water
is able to fully circulate.
WARNING: Do not to use an aerosol spray near
the appliance when it is in use or while the
appliance remains hot.
WARNING: Ensure that curtains close to the
cooker cannot ignite even when displaced by a
prevailing draught.
