a) Burn dry soft wood in the daytime and dry hard wood
overnight if possible.
b) Avoid using ‘green’ wood on overnight banking as
creosote deposits will be increased.
c) Using hard wood in the daytime will give prolonged
burning but heating response will be slower.
d) Before refuelling, open the flue chamber damper to its
full extent and fill the firebox up to the bottom of the
firedoor opening, ensuring the secondary air slide is at
fully open.
All Fuels Using Wood and Paper
a) Check the flue pipe is free of blockage.
b) Open firebox door.
c) Open ashpit door.
d) De-ash (Fig. 7) and remove dead fuel from
bottomgrate, rake fuel into ashpan.
e) Remove ashpan, empty and replace (Fig. 8).
f) Open flue chamber damper to maximum (Fig. 9).
g) Flue dilution lever fully to ‘left’ (flue chamber door
closed, Fig. 9).
h) Lay a liberal supply of wood and paper on top of the
bottomgrate bars together with a small quantity of fuel
and light.
i)
Close and lock the ashpit door
with the spinwheel
control open.
j)
Close and lock the firedoor.
k) With fire established, open firebox door and fill firebox
with fuel. Check secondary air slide setting (Fig. 10).
Close and lock firebox door
. Push flue chamber
damper back to position which has been found to give
desired burning rate.
All Fuels Using a Gas Poker
a) Check the flue pipe is free of blockage.
b) Open firebox door.
c) Open ashpit box.
d) De-ash (Fig. 7) dead fuel from bottomgrate, rake fuel
into ashpan. Insert flay bayonet type gas poker on top
of bottomgrate bars.
e) Remove ashpan, and empty (Fig. 8).
f) Open flue chamber damper to maximum (Fig. 9).
g) Flue dilution lever fully ‘left’. (flue chamber door
closed, Fig. 9).
h) Lay a 75-100mm (3ins-4ins) shallow depth of fuel onto
the bottomgrate and light gas poker.
i) Close the ashpit and firebox doors as far as possible -
spinwheel control open.
j. When the fuel is well alight, extinguish and remove
the gas poker, replace the clinker door and ashpan,
close and lock the ashpit door
with the spinwheel
control open, close the firedoor.
k) With the fire established, open the firebox door and fill
firebox with fuel. Check secondary air slide setting
(Fig. 8).
Close and lock the firebox door
. Push the
flue chamber damper back to position which has been
found to give best results. Set spinwheel to give
desired burning rate.
NOTE: IF THERE IS DEAD FUEL IN THE GRATE,
DROP THE BOTTOMGRATE TO REMOVE THE FUEL
UNLESS A GAS POKER IS GOING TO BE USED - SEE
UNDER ‘TO DUMP THE GRATE’.
1. The ashpit door spinwheel does not require to be open
for more than:-
a) Coke - Five complete turns
b) Other recommended fuels - Three complete turns
during cooking period.
2. Ensure the chimney damper is fully open prior to
refuellng and the secondary air slide is set in the
position relevant to the fuel used.
3. With the firedoor only open, fill the firebox to the
recommended level of the bottom firedoor opening
(not above) and
close the firedoor
. A deep bed of
newly charged fuel on a low fire will take time before
the heat reaches the oven, hotplate and boiler. When
burning coal or Anthracite, allow several minutes for
the new charge to ignite before changing the damper
setting.
4.
Once refuelling has been completed, close the
firedoor immediately and open only for re-fuelling.
