OR QUALITY TO FUEL SUPPLIER.
IMPORTANT: FUELS SHOULD BE OF THE CORRECT
SIZE FOR THE STOVE OTHERWISE THE APPLIANCE
WILL NOT GIVE A SATISFACTORY PERFORMANCE.

a. Open the firedoor, Fig. 1
b. Lay a liberal supply of wood/paper on the grate

together with a small quantity of fuel and light the
paper. Alternatively place four firelighters equally
spaced across the grate. Cover with fuel and light.

c. Close and lock both firedoors. See Fig. 1 and set the

thermostat knob to high (No.8) Fig. 2.

d. With the fire established open the firedoors, fill firebox

up to the top of the front firebar and sloping upwards
to the back.

e. Close and lock the firedoors. Fig. 1 with the operating

tool. THIS IS ESSENTIAL TO ACHIEVE CONTINUAL

SAFE RUNNING EFFICIENT OPERATION OF THE
STOVE.

f. Adjust the thermostat knob, Fig. 2 to give the desired

rate of burning.

g. Replace operating tool on its support cradle when not

in use. See Fig. 3.

DE-ASHING AND ASH REMOVAL

2. The doors must be left slightly ajar until the top of the
fuelbed has flames passing through it.

3. The appliance doors should be then closed and locked.

WARNING: IF THE DOORS ARE CLOSED TOO EARLY,
THEN PUFF-BACK CAN BE EXPERIENCED. THESE ARE
SMALL EXPLOSIONS WHERE SMOKE COULD BE
FORCED THROUGH THE DOOR SEAL OR AIR INLET
INTO THE ROOM. THE APPLIANCE MUST NOT BE LEFT
UNATTENDED OR OPERATED FOR LONG PERIODS
WITH THE DOORS OPEN AS THIS COULD CAUSE
PHYSICAL DAMAGE TO THE APPLIANCE.

Maximum burning rate is obtained with the thermostat
control knob set to 8 (high) and (1) low minimum rate.
Adjust as required to suit the fuel and the heating desired.
A fully fueled fire will last four hours (when burning solid
fuel) at the maximum recommended burning rate before
refuelling is required. Avoid clinker formation which
indicates overfiring and always check that the firedoor is
locked.

De-ash thoroughly refuelling and ensure there is a sufficient
amount of hot fuel in the firebed before loading.
Fuel fire up to the top of the front firebar sloping the firebed
upwards to the back of the firebox.
Close or nearly close the thermostat by setting the knob to
No. 1 setting. Experience will indicate the setting that
provides the best results with the fuel being burnt.

NOTE: DIFFICULTY ON OBTAINING BANKING CAN BE
SOMETIMES OVERCOME BY THE USE OF SMALLER
SIZE FUEL E.G. SUNBRITE SINGLES.

The supply of hot water is dependent on the rate of burning
and is greatest with the thermostat set at 8 (high), and least
when the thermostat is set at 1 (low). The boiler is
designed to heat radiators as well as supply domestic hot
water. Fuel consumption will be higher when heating
radiators and these should be turned off when not required.
If your central heating pump is controlled by an axillary
clamp-on thermostat fitted to the heating return side close
to the stove. PLEASE DO NOT ADJUST FROM ITS
INTENDED SETTING OF 50˚C (122˚F).

a. Riddle the bottomgrate by engaging the operating tool

on the riddling shaft - Fig. 4 and rotate/reverse it sharply
for about 10 strokes by which time the fire should be
free of ash. Riddle the grate at least twice daily (more
often if required) and always before re-fuelling.

b. Open the locked firedoors with the operating tool.
