2.1 OPERATION
The operation and maintenance of the product during operation is fairly simple since the construction of the
product guarantees defined condition for burning the fuel and only WOODEN PELLETS with clearly guaranteed
quality values are used as the exclusive fuel.
1) Refilling the bin with fuel
It is necessary to keep the level of fuel at least 10 cm above the opening for the feeder F1 at all times. If the level
of fuel go down (decreases), the supply of fuel may be irregular.
Guaranteed fuel for products of KP series are wooden pellets the basic parameters of which are given in the
table:
Wooden pellets - diameter 6.0 - 8.5 mm
Calorific value approximately 16-18 MJ / kg resp. 4.5 – 5 kWh / kg
Content of water up to 10 %
Ash content up to 1 % ( 0.8 - 1.0% )
Bulk density 0.6 up to 0.64 Kp / dm

Fuel supply system
PE/PP bags of 10 up to 25 kg, Big Bags of 800 up to 1100 kg, in bulk (cistern)
Table number 1 - Fuel and its parameters
Note:
Whow offen to fill the fuel bin?
It depends on:
- size of the bin
- average output of the boiler at the given time period.
- quality of the fuel used
Anticipated interval: ……………………………………… once a week
Note:
There can be a seasonal bin installed together with the boiler. Filling of the bin is controlled by its own
automatic or manual control system.
2) Emptying of the ashtray.
In general, the ash always has to be removed when the level of ash reaches approximately 2 cm below the side
edges of the ashtray.
Anticipated interval……………………………………once every 2 weeks (KP 10-20-11-21)
……………………………………once every 2 up to 5 days (KP 50, KP 51)
Note:
Emptying period of the ashtray depends on the following effects:
- device power output (amount of fuel burnt in the given period)
- fuel quality
- chimney draught
- type of the installed device
Always PAY ATTENTION to prevent the operator from being affected by fire from the combustion
camber and to seal the boiler door carefully (tight) after every visual check of the combustion or
after removal of ash etc. Half-way closed door is a cause of elevated fire hazard and also degrade
the fuel burning process.
