OPERATING THE COOKER
Fig.15
FUELLING
Using the recommended fuels, access is through
the fire door or the fuelling cup. To fuel, lift and tilt
the Fire Fence outwards. Note: When burning
timber logs the fire fence may be removed to
simplify front loading, make sure that the logs are
no longer than the recommended size so that the
fire door can be fully closed.
When refuelling open the fire damper. After
refuelling be sure to close the damper otherwise
oven temperature will drop and the fire box may
overheat.
CONTROL
The air supply to the fire is controlled by the spin
valve situated on the ash door. Depending on the
setting a high or low firing condition will be
determined by the volume of air passing through at
any one time.
DIRECT FLUE DAMPER
The direct damper as already advised must be kept
closed at all times except when kindling a new fire
or refuelling.
A secondary flue damper position can be used
which allows the damper to be partly opened to
give better burning in marginal draught conditions.
OVEN DAMPER
When using oven, operate damper in open position.
OVER-FIRING
When using anthracite, coke or coal avoid
excessive firing conditions. High temperatures are
unnecessary and can only do serious harm to the
cooker. The first indication that overheating is
taking place will be the formation of Clinker (Melted
Ash) in the firebox and this should be removed
immediately otherwise damage will occur not only
to the cooker components but also to the fire bricks
and any damage here should be repaired without
delay.
THE HOTPLATE
For best results use heavy based, flat bottomed
utensils. When cleaning your cooker ensure that
the underside of the hot plate is also attended to as
hard carbon and soot can build up here to such a
degree that the surface of the hotplate is being
insulated from the fire and this will, of course,
drastically reduce efficiency.
MAIN OVEN
When baking or roasting, open the oven damper
and Spin Valve fully until the thermometer shows a
temperature about 50
o
F (10ºC) higher than that
which is required. Then close the Spin Valve to a
point where the required temperature is sustained
(a little practice will soon show how much
adjustment is necessary). Much will also depend
on the strength of the chimney draught. Remember
the direct flue damper must be kept fully closed as
a by-pass is provided to allow waste gases through
at all times. When baking or roasting, if it is found
that the surface of the food is cooking too quickly
then position the plain steel shelf in the top of the
oven so as to act as a heat shield which will protect
the food on the shelf beneath.
