15
(ca. 10 cm) (chopping of the wood in about 5 cm pieces at the rst stage of burning up ac-
celerates embers’ producing)
8. Wait for 15÷20 minutes for the ember layer occurring
9. Fill up the whole combustion chamber
10. Close the upper and bottom door hermetically
11. Pull the chimney ap and switch on the fan
WARNING!
It is forbidden to switch on the fan when the upper door is opened.
IMPORTANT!
It is important to pay an attention on both depth of gasication chamber and thick-
ness of the upper door while chamber’s loading. If wood’s sizes aren’t adequate to the
elements mentioned above it may be difcult to close boiler’s door or load the cham-
ber with wood. You must not close the door by force - it may cause door’s damage.
IMPORTANT!
Wood storing for about a year ensures its right humidity (admissable humidity - 25%
- look at TECHNICAL DATA section). Advisable humidity level (15%) is to be obtained
after 2 years wood storing (look at the diagram no 5).
6.6. Fuel loading
If the boiler is chosen adequate to the place to be warmed up there is one loading for 8÷12 hours
needed. It is advisable however to control the boiler every 5÷7 hours. To control wood quantity
you should:
1. Switch off the boiler with the main switch,
2. Open the chimney ap,
3. Open the upper door and load the chamber if it’s necessary,
4. Close the door, chimney ap and switch on the boiler
It is important not to let the fuel to get between combustion chamber and chimney ap as it
would obstruct chimney ap’s closing.
When loading (it is recommended to burn out the fuel up to embers) there is a need of taking
down ash deposited on the loading chamber’s sidewall.
NOTICE!
Lack of fuel is signalled with a yellow indicator “no fuel”
