NOTE: THE PRECISE AMOUNT OF OPENING
DEPENDS ON THE CHIMNEY DRAUGHT AND THE
TYPE/CONDITION OF WOOD TO BE BURNT. THIS
MAY TAKE 2 OR 3 DAYS TO ASCERTAIN.
If the fuel does not burn but ‘dies out’, the draught should
be increased by increasing the opening setting of the flue
chamber damper.
NOTE: BUILD-UP OF CREOSOTE DEPOSITS IN THE
FLUE AND CHIMNEY CAN IN TIME, LEAD TO A
CHIMNEY FIRE.
THESE DEPOSITS CAN BE PREVENTED BY THE
REGULAR USE OF A PROPRIETARY BRAND OF
CHEMICAL CREOSOTE REMOVER, WHICH
REDUCES THE ADHESION STRENGTH OF THE
CREOSOTE DEPOSITS.
IMPORTANT: CHEMICAL CLEANERS MUST NOT BE
CONSIDERED AS AN ALTERNATIVE TO CHIMNEY
SWEEPING, ONLY AS SUPPLEMENTARY.
ALWAYS DE-ASH BEFORE RE-FUELLING.
Open the ashpit door to give access to the ashpan (See
Fig. 9).
In winter, this may be as much as three times daily
depending on weather severity.
Cooker usage governs the frequency of re-fuelling.
NOTE: DO NOT ALLOW ASH TO ACCUMULATE IN
THE ASHPAN UNTIL IT TOUCHES THE UNDERSIDE
OF THE BOTTOMGRATE BARS OR THEY WILL
QUICKLY BURN OUT.
Ensure the ashpan is fully home otherwise the ashpit
door may not close and lock completely.
Leaving the ashpit door open will cause the fire to ‘run
away’ and may cause damage if left unattended.
The best results can be obtained by using machined
base utensils. The hottest part of the hotplate is
immediately above the fire, the other end being for
simmering.
The circular plug in the hotplate (near the flue chamber
end) is for flue cleaning and must not be removed for
cooking.
Keep the hotplate clean with a wire brush.
NOTE: TO OBTAIN OPTIMUM HOTPLATE
PERFORMANCE FOR FAST BOILING OR HOTPLATE
COOKING, FUEL THE FIREBOX WITH 1 OR 2 LARGE
LOGS.
WARNING: THE COOKER TOP PLATE SURFACE
AROUND THE HOTPLATE WILL BECOME HOT
UNDER USE AND CARE MUST BE OBSERVED.
PLEASE REFER TO THE INSTALLATION
INSTRUCTIONS REGARDING MINIMUM
CLEARANCES TO COMBUSTIBLE SURFACES AND
MATERIALS.
The correct adjustment of the spinwheel and flue
chamber damper to obtain the oven temperature required
varies with the chimney draught, and can be found only
by experiment. The following is a suggested method
only, and may need modification to suit local conditions.
Suppose an oven temperature for roasting is desired,
and that the cooker is idling.
Thoroughly de-ash the fire as described in the respective
paragraph, and re-fuel. Set the flue chamber damper to
No. 3 setting and open the spinwheel as described under
‘COOKER CONTROL’.
As soon as the fire produces flame, close the flue
chamber damper. Do not allow the fire to run away.
The temperature of the oven should now rise steadily.
When it reaches a point about 50°C below that required,
close the spinwheel to approximately 1/4 turn open.
Thereafter control the temperature of the oven by
adjusting the spinwheel.
NOTE: THE METHOD SHOULD PROVE SUCCESSFUL
IN ALMOST ALL CASES, BUT IF CLOSING THE FLUE
CHAMBER DAMPER CAUSES THE FIRE TO SMOKE,
IT SHOULD BE OPENED GRADUALLY UNTIL THE
SMOKING STOPS.
Keeping the fuel level low will make the oven more
controllable.
The oven may be cleaned with a stiff wire brush, when it
is very hot.
