j) With the fire established open the firebox door and fill
firebox with fuel. Check secondary air slide setting
Close and lock the firebox door
.Push the flue
chamber damper back to position which has been
found to give best results. Set spinwheel control to
give desired burning rate.
Set the spinwheel open. The precise amount will be
shown by experience with the appliance, 2-3 turns will do
to start.
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.
The appliance is designed for continuous burning and the
best results will only be obtained if it is allowed to burn
overnight. It is no more expensive in fuel costs.
Last thing at night, de-ash the fire, empty the ashpan and
fully refuel.
Ensure that the firebox and ashpit doors are securely
closed
, and after closing the spinwheel, re-open it a
quarter of a turn.
NOTE: THE BEST POSITION FOR THE FLUE
CHAMBER DAMPER CAN BE FOUND ONLY BY
EXPERIMENT BUT ALWAYS TRY THE LOW SETTING
FIRST.
In the morning, open the spinwheel fully. Open the flue
chamber damper to maximum. When it is burning
brightly, close the flue chamber damper to halfway and
lightly re-fuel, if the hotplate is required immediately.
Re-set the flue chamber damper.
