open the flue chamber damper to maximum and riddle
the fire. When it is burning brightly, close the flue
chamber damper, but do not refuel before use if the
hotplate is required immediately, unless there is a risk of
the fire going out.
All Fuels.
Set the cooker/boiler damper knob ‘H’.
Close spinwheel.
To regulate burning, set the boiler thermostat knob to ‘8’
(high) or minimum rate ‘1’ (low).
Adjust as required to suit desired water heating.
Overnight banking and daytime slow burning should be
obtained with the boiler thermostat knob set at ‘1’ to give
extended burning.
Wood burning
Some woods are more difficult to burn therefore it may
be necessary to open the spinwheel in addition to the
thermostat to obtain the desired results. The spinwheel
must be closed as appropriate. Do not leave the cooker
for extended periods with the spinwheel open as the
cooker may overheat and cause damage.
In some circumstances it may be possible to overheat
the appliance and the water inside will boil. This will be
evident by the sound of a knocking noise coming from
the appliance and pipes around the house. If this occurs
close off all air controls and manually start the central
heating pump if fitted. Opening the oven doors and
hotplate covers will help to release heat from the
appliance. Be aware that steam and boiling water will be
expended from any open vent from the heating system
probably in the roof space at the expansion tank.
In the unlikely event that the appliance is not operating in
freezing conditions the water must be drained from the
boiler to prevent frost damage.
Solid Fuel
The appliance may be operated overnight for the
purpose of selected central heating when inclement
weather conditions occur.
Set the cooker/boiler damper knob to ‘H’ after refuelling
etc. and the boiler thermostat knob to No. 2 with the flue
chamber damper set at minimum. The spinwheel should
be closed and about four radiators can be run overnight
under these conditions.
NOTE: THE HOTPLATE AND OVEN TEMPERATURE
WILL BE CONSIDERABLY LOWER AND EXTENDED
TIME WILL BE NEEDED TO HEAT UP THESE
FEATURES. DO NOT FORGET TO RE-SET THE
COOKER/BOILER KNOB TO ‘C’ FOR COOKING
AFTER OVERNIGHT USE.
Wood
The appliance is designed for continuous slumbering
overnight for up to a maximum of 10 hours depending on
the type of dry wood being used. Last thing at night, open
the flue chamber damper. de-ash the fire, empty the
ashpan and fully refuel.
Ensure that the firebox and ashpit door are securely
closed, close the spinwheel tight and the flue chamber
damper is set to No.1.
Set the boiler thermostat knob to its minimum setting
and the front damper knob to ‘c’.
Turn the flue dilution lever (See Fig. 11) from left to right
hand so that the flue chamber door opens at the bottom
and minimise burning rates.
NOTE: THE PRECISE AMOUNT OF OPENING
DEPENDS ON THE CHIMNEY DRAUGHT, THE
TYPE/CONDITION OF WOOD TO BE BURNT AND
THIS MAY TAKE 2 OR 3 DAYS TO ASCERTAIN.
1. If the fuel in the firebox is exhausted prematurely, the
overnight chimney draught must be reduced by
increasing the opening setting of the flue chamber
door, using the flue dilution lever.
2. If the fuel does not burn but ‘dies out, the draught
should be increased by reducing the opening setting.
of the flue chamber door, using the flue dilution lever.
It maybe necessary to set the thermostat to a higher
number to allow more air.
Following overnight banking, the flue chamber door must
be closed, the spinwheel and flue chamber damper
opened and the fire refuelled.
Immediately the new fuel has caught alight, close the flue
chamber damper.
NOTE: BUILD-UP OF CREOSOTE DEPOSITS IN THE
FLUE AND CHIMNEY CAN IN TIME, LEAD TO
CHIMNEY FIRE.
THESE DEPOSITS CAN BE PREVENTED BY THE
REGULAR USE OF A PROPRIETARY BRAND OF
CHIMNEY CLEANER, WHICH REUDCES THE
STRENGTH OF THE CREOSOTE DEPOSITS.
IMPORTANT: CHEMICAL CLEANERS MUST NOT BE
CONSIDERED AS AN ALTERNATIVE TO CHIMNEY
SWEEPING, ONLY AS SUPPLEMENTARY.

a) Using the cooker boiler to provide heat for domestic
hot water and radiators in the winter, a boiler thermostat
setting at No.8 is recommended.
b) Using the cooker boiler for the provision of domestic
hot water only, in the summer, a boiler thermostat setting
of No. 5 is recommended.
