Chimney fires

In the event of a chimney fire – which often re-
sults from incorrect operation or protracted fi-
ring with moist wood – close the door and shut 
off the secondary/start-up air supply to smother 
the fire. Call the fire department.

Airflow regulation

To adjust combustion airflow, use the handle 
on the side (towards the rear). There is maxi-
mum combustion airflow in when the handle is 
in the top position (fig. 1). Reduce combustion 
airflow gradually by lowering the handle. When 
the handle is in the lowest position (fig. 2), com-
bustion airflow is completely closed. 

The SL805 Aqua stoves are designed and tested 
to burn extremely cleanly with very little smo-
ke discharge and are exempt for use in smoke 
control areas throughout the UK when burning 
dry wood logs.  To comply, a permanent stop is 
fitted to ensure that the air control slider cannot 
be closed beyond 52% of its fully open position. 
A permanent amount of air will therefore enter 
the firebox to feed the fire producing negligible 
amounts of smoke and unburnt hydrocarbons.  
The appliances will only be considered as an 
exempt appliances if this stop is in place.

Lighting the stove

Place two pieces of wood on the bottom. Stack 
kindling on top in layers with air between. Set-
ting fire starter (bag, brick, paraffin) on the top, 
now you are ready to light the fuel. The flames 
must work from the top down. 

The use of lighter fluid, oils or 
any liquid fuels is strictly forbid-
den from use in a wood stove.

Fully open the combustion air and leave the 
door ajar (about 1 cm open).

Once the fire is established and the chimney is 
hot (after about 3-5 minutes) closed door and 
regulate the air into operating position. We re-
commend, all of the first fuel is burned with the 
combustion air fully open in the operating po-
sition. This ensures the stove and chimney are 
thoroughly heated.

Startup/Lighting

Refuelling

A fresh supply of fuel should normally be added 
while there is still a good layer of hot embers. 
Spread the embers over the base grate, most 
towards the front of the stove. Lay a single layer 
of wood fuel corresponding to about 1.5 kg over 
the embers, at right angles to the stove door. 
Turn handle into top position (max.  Combusti-
on- airflow). Keep door ajar if necessary. (The 
door should not be left open but fuel will ignite 
more quickly while the door is ajar.) The wood 
should ignite within a very short time (usually 
1-3 minutes). If the door is ajar, close it as soon 
as the fuel is ignited. When the flames spread 
across the fuel stack, adjust the combustion air-
flow to the required level. Nominal operation 5.5 
kW corresponds to 80% combustion airflow. 
When adding fuel, make sure that the fuel is not 
too tightly packed, as this will lead to poorer 
combustion and fuel inefficiency.
Never fill firewood over the stove’s max. fill line.
