Choice of fuel
Should you burn smokeless fuel or wood? If you are located in a smoke control zone, then you have to burn
an approved smokeless fuel. The boiler output will be higher with solid fuel than wood. Solid fuel is a more
concentrated energy source, therefore it is possible to load the firebox with more potential energy in the form
of solid fuel than wood. It will also burn a longer period without refuelling for the same reason.
When burning solid fuel it is important to de-ash the grate prior to refuelling, to ensure maximum airflow
through the bed of coals, whereas with wood it is preferable to leave the firebox undisturbed and allow ash to
build up on the grate. To minimise the chance of the cooker smoking back when you refuel, before opening
the fire door open the flue damper and set the oven/boiler control to the oven mode. Allow a minute or two
for the airflow within the appliance to stabilise, then slowly open the firedoor and refuel. If you encounter
frequent smoking back, have the chimney draught checked to ensure it is a minimum of 0.6”wg. check the
flueways in the cooker have not become blocked with soot or tar, similarly the flue and chimney.
COOKING IN THE OVENS
The cooker has 2 ovens. Please refer to the table for comparable temperature guides in degrees Centigrade.
Temperatures given are approximate and based on refuelling solid fuel at approximately 1.4kg hour, with
cooker set to ‘oven’ mode, flue draught 0.07” w.g.
Opening the flue damper will allow heat to pass directly to the chimney via the left side of the hotplate,
useful for boosting the hotplate temperature without increasing the main oven temperature if required.
The temperature dial on the main oven door provides an indication of the oven temperature (See Fig.2) and
by comparison the temperature of the adjacent oven. Since the dial is in the door, the thermometer will
register a lower temperature when the door is opened although the oven itself will not loose temperature
so quickly. The dial can take a short time to register the correct temperature once the door is again closed.
The ovens are all of equal depth and each is equipped with wire shelves which can be set to the desired
height. The shelves have anti-pull out stops on their ends to prevent them from being pulled out
inadvertently; to remove a shelf, pull forward until the stop is reached, then lift at the front and pull out
of the oven. Use reverse procedure to refit. If the shelves pull straight out then they are in back to front!

ASH REMOVAL
When burning wood, only remove small
amounts of ash from the grate, leaving ideally
30mm depth of ash in the bottom for best
performance.
When burning solid fuel, de-ash regularly.
