THERMALUX SLOW COMBUSTION COOKING STOVES
OPERATING INSTRUCTIONS
1. Firstly check that the stove has been safely
and correctly installed and that the hot water
system (if connected) has been filled with
water.
2. Suitable Fuels
The stove can burn any type of wood or coal.
However the wood must be dry; usually dried
for two or more years after cutting down and
then kept dry prior to burning.
Woods containing a lot of resin, eg. pine,
should only be used when the fire is burning
briskly, as they may cause severe flue deposits
when burnt slowly. Dry hardwood or coal
should be used for slow overnight burning.
3. Controls (Clarendon, Supreme & Grand
Cuisine) (See additional instructions for
CD & Grand Cuisine)
The Thermalux has 2 air intakes, each
controlled by a SPIN WHEEL one on the
ashpan door and one on the firebox door.
The stove also has a Flue Damper and Dilution
control knobs which are located on the front
right hand side of the stove.
Note: The Damper and Dilution controls
are combined into one control knob on the
Clarendon Stove.
Firebox Air Control
This is mainly used when burning wood. Fully
open for fast burning and closed for overnight
burning. Set in between to obtain desired fire
temperature.
Ash Door Air Control
This is the main air control especially when
burning coal or briquettes. Fully open for fast
burning and closed for overnight burning. Set
in between to obtain desired fire temperature.
Damper
This prevents loss of hot gasses up the flue
and slows the fire for steady burning. Fully
open to light the fire and when refuelling but
closed when fire is established. Fully closed for
overnight burning. (This may vary according to
individual flue draught).
Dilution Control (Not relevant to
Clarendon as the damper & dilution
control are combined)
In normal daytime use, this will remain closed.
It may be opened when the fire is shut
down for long periods of slow burning – eg
overnight. This control introduces warm dry
air into the base of the flue. It serves two
purposes: 1. To reduce condensation and
creosote build-up in the flue, when the fire
is burning very slowly and 2. To control the
flue draught in conjunction with the firebox
air controls to achieve longer overnight burn
times, however in many installations the use
of the Dilution control is not required.
Solid Oven Tray
The solid oven trays can be used for direct
baking of scones and biscuits and can also
be placed near the top of the oven to reduce
heat radiating from the top of the oven. When
cooking a roast or cakes which need extended
cooking times, remove the solid oven tray
and place in cool spot. 20 to 30 minutes into
cooking procedure slide the cool tray into the
top oven shelf position. This will cushion heat
that may burn the top of the food.
Temperature Gauge
The temperature gauge is mounted in the
oven door which is the coolest part of the
oven, especially if the door has been recently
opened. As such it will be generally found that
oven temperatures will be higher than those
shown on the gauge. Experience will show
which is the best gauge temperature for each
individual dish.
4. Lighting Up
Open firebox and ash door air controls and the
damper. (Close the dilution control if fitted).
Open the firebox door, set paper, kindling and
small timber (Fire lighters may be used). Ignite
the paper and close the firebox door. When the
kindling is well alight then add some slightly
larger wood until the fire is well established.
Some people open the ashpan door with the
firebox door closed to get increase draught for
lighting the fire.
Extreme caution must be taken if ever
this is done, and in no circumstances
leave the stove in this condition even for
a few minutes. If the stove is left in this
condition for more than a few minutes
extreme temperatures can be reached.
Once the fire is established, load up with wood
or coal, partly or fully close the damper and
leave the air controls open.
From cold, the oven can reach operating
temperature in about an hour. The hotplates
can be used almost immediately the fire is
established. In practice the stove is kept alight
most of the time and so all that is required is
that more fuel is added and the air control
opened a little while before the oven is
required.
If the oven is being quickly heated, slow the
fire before the required oven temperature is
reached, as the heat in the firebox will cause
the temperature to keep rising for several
minutes after the fire has been slowed down.
