FUELLING WITH WOOD OR PEAT

The cooker will satisfactorily burn wood logs, blocks or
peat briquettes, but logs should be perfectly dry in order
to obtain the best cooker performance and minimise the
deposits of creosote. Wet logs may also provide
overnight banking problems and the following hints are
recommended:-
a) Burn dry soft wood in the day time 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 day time will give prolonged
burning but heating response is slower.
d) Wet kitchen refuse should not be burned.
e) Before refuelling, open the flue chamber damper to its
full extent and fill the firebox up to the bottom of the
firedoor opening.
f) To obtain the optimum burning rate both grate baffles
must be located on the top face of the reciprocating
bars at the rear of the firebox. (See Fig. 4). Grate
riddling is not required.

LIGHTING THE FIRE

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 and remove ashpan, empty and replace (Fig.
9).
f) Open flue chamber damper to maximum (Fig. 7).
e) Flue dilution lever fully to 'left' (flue chamber door
closed, Fig. 7).
f) Lay a liberal supply of wood and paper on top of the
bottomgrate together with a small quantity of fuel and
light.
g) Close and lock the ashpit door with the spinwheel
control open.
h) Close and lock the firedoor.
i) With fire established, open firebox door and fill firebox
with fuel. Check secondary air slide setting (Fig. 6).
Open - heating, closed - cooking.
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 flue pipe is free of blockage.
b) Open firebox door.
c) Open ashpit door.
d) De-ash (Fig. 8) and remove clinker door (Fig. 10).
Insert flat bayonet type gas poker on top of
bottomgrate bars.
e) Remove ashpan and empty (Fig. 9).
f) Open flue chamber damper to maximum (Fig. 7).
g) Flue dilution lever fully to 'left' (flue chamber door
closed, Fig. 7).
h) Lay a 75-100mm 3"-4") 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. 6). Open - heating, closed - cooking.
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.

COOKER CONTROL

Heating Only
a) The fire is controlled by using the spinwheel on the
ashpit door to govern the air supply.
b) The adjustable flue chamber damper is for reducing
the chimney draught, and the more it can be closed,
the easier the cooker is to control. The line markings
on the flue chamber enable you to repeat the best
settings to suit your chimney, from No.1 in a closed
position to No.6 fully open.
c) Control over the direction of the flue gases is
