Volume Of Wood To Add Per Hour; Heating Output Regulation - Spartherm XS 500 Installation And Operating Instructions Manual

3.4.2 Volume of wood to add per hour

In order to avoid damage caused by overheating e.g. discolouration of the
steel, deformation etc. and to guarantee optimal functionality for many years,
the fireplace cassette must be correctly fuelled. Any danger of overheating
can be excluded when the maximum heating output is not exceeded.
You can read about the volume of wood to add per hour in section 2.3
"Technical Data". The circumference of the individual wooden logs
should be approx. 20-25 cm!
Please note: Larger volumes of wood lead to overheating and damage to
your fireplace cassette. Wood briquettes have a significantly higher heating
output than hardwood. The volume of wood briquettes added per hour should
therefore be kept to at least 20% less than when using chopped wood (see
2.3).
We reject all guarantee claims resulting from damage caused by
overheating (too much wood added per hour).
The maximum amount of fuel specified in this manual should not be
exceeded, overloading can cause excess smoke.
Regulation of the heating output is achieved through the volume of fuel
added to the fire. Do not try to slow down the burning process by reducing
the air supply too severely. When burning wood, this will lead to incomplete
burning and, therefore, to wasted fuel and unnecessary environmental
pollution because the wood is degassed even when no flames occur. This
also leads to increased sooting of the glass panel! In addition, there is a
danger of deflagration (explosion-like inflammation of the smoke gasses).
Ensure that the firebox door is always firmly shut so that the burning process
is not accelerated through the uncontrolled feeding of air.
The heating output of your fireplace cassette is also dependent on the
"drawing" performance of your chimney. The "drawing" performance of the
chimney can be influenced by the size of the opening to the chimney or by
environmental conditions such as strong winds etc.
6. End of the fire:
This is achieved when the wood has been completely
burnt, there is no smouldering fire and no incomplete
combustion can occur. The control lever can now be
closed.
When your fireplace cassette is not being operated,
always set the control lever to the position "Air
supply closed" (see Fig. 8).
