Operational Problems; Chimney Fires; Maintenance; Cleaning The Glass - Heta Vista Operating And Installation Instructions

It is advised not to use oil-containing woods
like teak tree and mahogany, as this can cau-
se 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

energy source, you save the environment about
1.3 kg CO every time you have used 1 kg nor-

mal wood.

1.11 operational problems

The chimney must be swept at least once a
year, we recommend the use of a NACS (natio-
nal association of chimney sweeps) registered
chimney sweep.
In the event of smoke or malodorous fumes are
being produced, you must first check to see
whether the chimney is blocked.
The chimney must, of course, always provide
the minimum draft necessary to ensure that it is
possible to regulate the fire. Please note, how-
ever, 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 baffle plate,
remove and clean it. In cases where the wood
burns too quickly, this may be due to excessive
chimney draft. You should also check to make
sure that the door seal and ash pan seal is intact
and correctly 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 efficiency, poten-
tially damaging the vermiculite and an increased
risk of soot deposits in the chimney.

1.12 Chimney fire
In case of a chimney fire, which often results from
incorrect operation/maintenance or prolonged
use of damp wood, close the door and the air
supply completely, to help slow/smother the fire.
Call the fire department.
The stove and chiminey must be inspected be-
fore use again.
1.13
The surface of the stove is treated with a heat-
resistant paint. The stove should be cleaned
with a damp cloth.
Any damage to the surface in the form of chips
or scratches can be repaired using touch-up
neutral heat/
2
paint, which is available in spray cans.

1.14 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.
