obtained by the setting of the cooker/boiler damper.
Set the cooker/boiler damper knob on the front of the
cooker to 'C' and the boiler thermostat knob on the
rear left hand corner of the top plate, to its minimum
setting.
d) Thermostat set at No.1 as domestic hot water is
obtained when cooking.
NOTE: INTERMEDIATE SELECTIVE SETTINGS OF
THE COOKER/BOILER DAMPER KNOB AWAY FROM
'C' WILL PROGRESSIVELY RESTRICT THE AMOUNT
OF HEAT TO THE TOP OF THE OVEN AND
INCREASE THE AMOUNT OF HEAT INTO THE
BOILER UNTIL THE KNOB IS POINTING TO SYMBOL
'H' FOR MAXIMUM WATER HEATING. IN THIS
POSITION, THE MINIMUM PROPORTION OF HEAT IS
DIRECTED TO OVEN HEATING. ALTHOUGH THE
OVEN WILL STILL GET HOT.
IF THE OVEN IS TOO HOT SET THE CONTROL TO H.
THIS WILL REDUCE THE OVEN TEMPERATURE BY
DIRECTING THE HEAT TO WATER.

Set the spinwheel open. The precise amount will be
shown by experience with the appliance, 2-3 turns will do
to start.
After setting the cooker/boiler damper knob to 'C', set the
flue chamber damper fully open after refuelling and reset
to position which has been found by practical experience
to give the best results. Do not try to obtain a fast
increase in temperature by opening flue chamber to its
fullest extent. This results in most of the heat being
wasted up the chimney.
Avoid excessive fire temperatures - they are
unnecessary and may do serious harm to the cooker.
The first symptoms of an overheated cooker is the
formation of clinker (melted ash) which will damage the
fire bricks.
Damaged firebricks should be replaced as soon as
possible but may be temporarily repaired with fire
cement.
Keep the ashpit door securely closed with the front
plate catch.
