The fire is controlled by using the spinwheel on the ashpit
door to govern air supply. The chimney damper in the flue
chamber is for reducing the chimney draught, and the
more the damper can be closed the easier the cooker is
to control. It is marked to enable you to repeat the best
settings you find suits your chimney
No.1
is closed
position and
No.6
when fully open.
Do not try to obtain a quick increase in temperature by
opening the chimney damper to its full extent. This results
in most of the heat being wasted up the chimney.
Avoid excessive fire temperatures with solid fuel - they are
not necessary and may do serious harm to the cooker.
The first sign that the cooker is being overheated is the
formation of clinker (melted ash), and clinker will damage
the firebricks. Damaged firebricks should be repaired with
fire cement or if necessary replaced as soon as possible.
Keep the ashpit door securely closed with screw
catch provided.
Main Oven
The correct adjustment of the spinwheel 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 the cooker is
idling.
Thoroughly de-ash the fire as described in the ‘
Riddling
’
paragraph, and refuel. Set the chimney damper to
No. 3
setting and open the spinwheel as described under item 1
of ‘
Fuelling
’. As soon as the fire has become nicely red all
through, close the chimney damper. Do not allow the fire
to become white hot. The temperature of the oven should
now rise steadily. When it reaches a point about 30ºC
(50ºF) below that required, close the spinwheel to
approximately one turn open. Thereafter control the
temperature of the oven by adjusting the spinwheel.
NOTE: THIS METHOD SHOULD PROVE SUCCESSFUL
IN ALMOST ALL CASES, BUT IF CLOSING THE
CHIMNEY DAMPER CAUSES THE FIRE TO SMOKE, IT
SHOULD BE OPENED GRADUALLY UNTIL THE
SMOKING STOPS.
The Warming Oven
The oven is primarily intended for heating plates and
keeping food warm. As a guide this warming oven is just
less than half the temperature of the main oven.
NOTE: THE DOORS SHOULD NOT BE SLAMMED
SHUT, OR THIS WILL WEAR AWAY THE METAL
RETAINER CATCHES.
The Hotplate
It is recommended to use the heatproof gloves supplied
when raising the dome lids to use the hotplate.
Replacement gloves can be obtained from the Aga Shop.
The best results can only be obtained by using machine
base utensils. The hottest part of the hotplate is
