CHOICE OF FUEL
FUEL: Wood
To obtain the maximum performance from your HYDROSYSTEM
fireplace stove, it is of primary importance to use
wood with suitable
characteristics
.
It is advisable to use
wood for heating such as
oak, beech, locust
tree, or oak
with good calorific energy, or logs of pressed wood that
do not have resin
.
These have a high calorific power and must
be used with caution to avoid overheating which could damage
the stove.
It is advisable to use
fuels such as
poplar, pine, lime tree, or
chestnut
which have low calorific power, since they are soft wood and
also they do not burn for a long time.
Avoid using
fuels such as
pine, fir, and olive
as they contain a high
degree of resin and their combustion may substantially soil the fire
mouth and the ceramic glass; also, they do not have an exceptional
yield.
For all types of wood listed, the humidity they contain is
essential because it determines the calorific energy.
Do not use treated fuels (such as painted or
varnished wood, or particle board) or unsuitable
materials (such as plastics and derivatives), which
could release toxic or polluting substances. Do not
burn rubbish.
The gases produced by combustion due the use of
unsuitable fuels cause damage to the fireplace stove
and the chimney, they cause pollution and can
compromise your health.
A high percentage of humidity produces condensation in the
smoke duct causing an alteration in the draught and
generating smoke and a significant deposit of soot on the
glass of the door and in the flue pipe with a possible risk of a
chimney fire later on.
At least once a month check that there are no creosote
deposits inside of the fire box and between the heater pipe;
if the surface is a shiny black and thick, IT SHOULD BE
CLEANED with the scraper provided or a similar tool.
5.4.
LOADING THE FUEL
For the loading of fuel, just open the door turning the handle upwards
as shown to the side.
During use, the metal parts and the glass reach high
temperatures, so it is necessary to use the special thermal
glove supplied.
During use it is also necessary to keep the door completely lowered
since intermediate positions cause abnormal combustion (forge effect),
with a consequent rapid consumption of wood and a drastically reduced
yield to the boiler.
