Installation and Operating Instructions for Heta SL800 Aqua stove Pevex1018/AH/ver1:Jan 2013
INSTRUCTIONS FOR USE
• The chimney is of the correct
height: at least 4.00 m above the
stove and free of the roof ridge.
First firing
The stove has been treated with a
heat-resistant coating which hardens
at a temperature of approximately 250
ºC. This hardening process causes the
production of smoke and malodorous
fumes, so the room must be very well
ventilated. During the first firing, which
should be carried out using approxi-
matly 1 kg. of wood, the stoking door
must be opened slightly every 10 mi-
nutes for the first two hours to prevent
the sealing rope sticking to the stove.
Fuel
Your new stove is EN approved for
firing with wood fuel. You must there-
fore only burn clean, dry wood in your
stove. Never use your stove to burn
driftwood, as this may contain a lot of
salt which can damage both the stove
and the chimney. Similarly, you must
not fire your stove with refuse, painted
wood, pressure-impregnated wood
or chipboard, as these materials can
emit poisonous fumes and smoke.
Correct firing using well seasoned
wood provides optimal heat output
and maximum economy. At the same
time, correct firing prevents environ-
mental damage in the form of smoke
and emmissions and also reduces
the risk of chimney fires. If the wood
is wet and inadequately seasoned, a
large proportion of the energy in the
fuel will be used to vaporise the water,
and this will all disappear up the chim-
ney. Thus it is important to use dry,
well seasoned wood, i.e. wood with
a moisture content of no more than
20%. This is achieved by storing the
wood for 1–2 years before use. Pieces
of firewood with a diameter of more
than 10 cm should be split before
storing. The pieces of firewood should
be of an appropriate length (approx.
25 cm) so that they can lie flat on the
bed of embers. If you store your wood
outdoors, it is best to cover it.
Fuels used in smoke control
areas
I
n a building in a smoke control area
you are legally only allowed to use this
appliance to burn dry/seasoned wood
logs of the maximum length given
above or authorised fuels. If you are
unsure if your property is located in
a smoke control area or need further
guidance on fuels you should contact
your Local Authority.
