1.3 General instructions of use
1.3.1 The wood, solid fuel
HK boilers are heating boilers, which use wood logs of forest wood. Almost all types of
woods will do.
The wood must be dry - moisture content lower than 25 %. This ensures good function of the
boiler and sufficient power.
NB: using wood with a moisture content lower than 15 % requires attention; do adjust the
primary air setting lower than normal to avoid ignited gas reentry to the wood log
compartment, which will result in intermediate gas combustion in this place, i.e. jumping
combustion.
If such situation occurs – be very careful if opening the wood log-filling door: explosive
backfire out the door can occur.
Old wood, woodworm, or having been a long time in a humid place is not suitable; it results
in power loss and incomplete combustion.
The wood must be chopped (10 to 15 cm of maximum diameter) and sawn in the length of
burning chamber to ensure a good function of the boiler without power loss.
Logs of 50 cm
Chopping and sawing the forest wood makes the quickest and most efficient drying
process. Stock it immediately under shelter (well aired, outside or inside). It must be
storage approximately two and half years to dry. Otherwise, a minimum of 3 years of
storage is necessary.
Wood exposed for a long time to bad weather or ageing (over 6 years) loses calorific
power: The consummation increases and the power from the boiler decreases. The
combustion is incomplete (soot and blackish-brown).
The boiler construction is not designed to work with treated wood from carpenters
workshops or industrial waste; a bad function will result as well as premature deterioration
of the boilers and their components.
1.3.2 Before the first use:
- Check the electronic and hydraulic connections.
- Purge the installation and check the pressure in the installation.
NEVER START THE BOILER WITHOUT WATER FILLING!
