stoking should burn down to embers before new 
logs are added. 
To obtain the best possible combustion, you 
should regulate the effect/heat output with the 
fuel and Air. Burning small logs provides more 
powerful combustion than burning large logs 
as the surface area is greater and more gas is 
released. 
The amount of wood in the combustion chamber 
is another factor that affects combustion. The 
optimum combustion is achieved by placing two 
logs in the stove. If you want an enhanced effect, 
you can add more logs. 
The ideal heat output is reached by burning 
approx. 1,5 kg per hour.

3.5 LIGHTING A FIRE WHEN USING WOOD

The fire lighting method is very important for 
starting combustion quickly and efficiently. 
1.  Open all  the Air control fully. 
2. Place a small log of wood crosswise in the 

combustion chamber and put 2 firelighters 
close to the log. Put a new small log close to the 
firelighters and place several sticks of kindling 
at an angle above it in a cross hatch shape. Air 
must be able to reach the firelighters, but the 
logs should be touching to “warm” each other. 
Light the firelighters with a match.

3. Keep the door approx. 1 cm ajar, until the glass 

is too hot to touch. Then close the door. When 
there are distinct, visible flames and the fire has 
taken hold. 

 

Warning:

 The control and handles will get warm 

when the wood burning stove is in use. Please 
use the glove provided when you operate the 
wood burning stove.

4. Once the first charge of wood has burnt away 

leaving a glowing bed of embers you should 
be able to shut of the primary air controls. 
Slowly open the stove door using the glove 
provided and re-stoke the fire with the desired 
amount of wood. Close the door and open the 
secondary  air control to maximum  for a few 
minutes to allow the new wood to catch fire 
then slowly push the air control back into the 
stove until the desired effect is reached.

In order to avoid the quenching of the stove 
fire by use of oversized logs we recommend a 
maximum wood fuel size of 4” (10cm) diameter 
by 10” (25cm) length split seasoned logs, with a 
maximum moisture content of 20%. 

This appliance is designed to operate with the 
door closed, except for lighting and reloading, 
failure to close the door during operation can 
result in fume spillage.

Warning:

 Properly installed, operated and 

maintained this appliance will not emit fumes 
into the dwelling. 
Occasional fumes from re-fuelling may occur. 
However, persistent fume emission is potentially 
dangerous and must not be tolerated. If fume 
emission does persist, the following immediate 
actions should be taken: 
Open doors and windows to ventilate room then 
leave the premises. Let the fire go out or eject and 
safely dispose of fuel from the appliance. 
Check for flue or chimney blockage, and clean 
if required. Do not attempt to relight the fire 
until the cause of the fume emission has been 
identified and corrected. If necessary seek expert 
advice

3.6 IMPORTANT INFORMATION FOR  

 

WOOD BURNING 

With a full load of wood and burning near 
nominal output the stove will need to be refuelled 
approximately every 1-1.5 hours. One or two large 
logs will burn longer than a number of smaller 
ones. 
Care must be taken that logs do not touch the 
baffle or the glass panel. Do not stack logs above 
the level of the tertiary air inlet profiling in the rear 
vermiculite firebox liners at the back of the stove.
Always make sure that flames are visible above 
the wood after re-fuelling for cleanest burning. 
Burning without flames above the fuel will create 
unnecessary smoke. After re-fuelling open the 
primary air control fully for 3 minutes or until the 
logs are fully blackened to achieve full flames 
above the fuel. 
Wood burns best on a bed of ash and it is 
therefore only necessary to remove surplus ash 
from the stove occasionally. Burn only dry, well-
seasoned wood, which should have been cut, split 
and stacked - under cover from rain - for at least 
12-24 months with free air movement around the 
sides of the stack to enable it to dry out. 
Burning wet or unseasoned wood will create tar 
deposits in the stove and chimney and will not 
produce a satisfactory heat output. Wood that 
is not properly dry (‘dry’ is considered to be less 
than 20% internal moisture content) uses up 
energy from the burn process to evaporate the
