Installation and Operating Instructions for Heta SL800 Aqua stove Pevex1018/AH/ver1:Jan 2013
The chimney must be swept at least
once a year, we recommend the use
of a NACS (national association of
chimney sweeps) registered chim-
ney sweep. In the event of smoke or
malodorous fumes being produced,
you must first check to see whether
the chimney is blocked. The chim-
ney must, of course, always provide
the minimum draught necessary to
ensure that it is possible to regulate
the fire. Please note, however, that
chimney draft is dependent on the
weather conditions. In high winds, the
draft can become so powerful that it
may be necessary to fit a damper in
the flue gas pipe to regulate the draft.
When cleaning the chimney, soot and
other deposits may come to fall on the
smoke turning plate.
In cases where
the wood burns too quickly, this may
be due to excessive chimney draught.
You should also check to make sure
that the door seal is intact and cor-
rectly fitting.
If the stove it generating too little heat,
this may be because you are firing
with wet wood. In this case, much of
the heating energy is used to dry the
wood, resulting in poor heating eco-
nomics and an increased risk of soot
deposits in the chimney.
OPERATIONAL PROBLEMS
MAINTENANCE
The surface of the stove has been
treated with heat-resistant paint.
The stove should be cleaned with a
damp cloth. Any damage to the sur-
face in the form of chips or scratches
can be repaired using touch-up paint,
which is available in spray cans.
Cleaning the glass
Incorrect firing, for example using
wet wood, can result in the viewing
window becoming covered in soot.
This soot can be easily and effectively
removed by using proprietary stove
glass cleaner.
VENTILATION
Adequate ventilation must be provided
in accordance with building regulati-
ons (Doc J Oct 2010) especially when
installing in newer build properties
when the stove is not going to be
installed to an outside air supply.
The Heta SL800 requires a permanent
air vent opening of minimum 550sq
mm under Building Regulations if
the stove is not going to be fitted to
an external outside fresh air supply.
Houses built after 2008 where the air
leakage rate is less than than 5m

then a ventilator equivalent to
550mm

per kW output will be re-
quired (9kW x 550mm = 4950mm

).
