Installation and Operating Instructions for Heta SL800 Aqua stove Pevex1018/AH/ver1:Jan 2013
It is advised not to use very oil-
containing woods like teak tree
and mahogany, as this can cause
damage to the glass.
Heating value in wood
You have to use about 2.4 kg normal
wood to replace one litre of heating
oil. All woods have almost the same
heating value per kg, which is about
5.27 kW/hour for absolute dry wood.
Wood with a moistness of 18% has a
efficiency of about 4.18 kW/hour per
kg, and one litre heating oil contains
about 10 kW/hour.
CO

release
At combustion 1000 litres of heating
oil forms 3.171 tons CO

. As wood
is a CO

neutral heat/ energy source,
you save the environment about 1.3
kg CO

every time you have used 1 kg
normal wood.
Chimney fires
In the event of a chimney fire – which
often results from incorrect operation
or protracted firing with moist wood
– close the door and shut off the se-
condary/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 maximum combustion
airflow in when the handle is in the
top position (fig. 1). Reduce combu-
stion airflow gradually by lowering
the handle. When the handle is in the
lowest position (fig. 2), combustion
airflow is completely closed.

The SL800 Aqua stoves are designed
and tested to burn extremely cleanly
with very little smoke discharge and
are exempt for use in smoke con-
trol 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 conside-
red as an exempt appliances if this
stop is in place.
Lighting the stove
To light the stove, use firelighters,
paraffin firelighter bags or small
pieces of wood. Place over the grate.
Place larger logs over the fire-lighting
material, at right angles to the door.
Turn handle to top position for max.
Combustion- airflow. The stove door
should be slightly ajar (about 1 cm).
When the wood is well lit and the
chimney is hot (after about 10 mi-
nutes), close the stove door. When
lighting the stove from cold, we re-
commend that the combustion airflow
is at maximum until the first stack of
wood has burned out so that the stove
and chimney are heated through.
