Boiler Operation; Cleaning The Boiler - Ladan 18 Instruction For Use, Installation And Assembly

Boiler operation:

Before making fire it is necessary:
- familiarize with the attendance of electronic boiler regulation
- check water pressure in the central heating system
- check if the boiler is connected to the mains
Making fire in the boiler
- set the heating temperature
- select the fan speed
- through the upper door insert paper, chips, small pieces of wood and to the rest of feeding
champer add more logs
- chimney flap must be opened!
- fire up the paper and close feeding door
- open the lower door and let the fuel approximately 20 min. flare
- after 20 min. close the lower door and chimney flap
- push down „K„ button to get run the burning mode
Refilling a loading chamber
the fan by pressing „K" button
- stop
- open the chimney flap
- CAREFULLY! open the feeding (upper) doors
- refill the fuel
- close the upper door and chimney flap
- press button „K„ to return to the previous state of the boiler
Warning
Be careful not to get any fuel during the refilling between the chimney flap and the flange. It
would make impossible to close flap correctly.

Cleaning the boiler:

When using dry wood and optimum fuel gasification the combustion chamber and heat
exchanger get sooted minimally. However, when using wet wood the walls of combustion
chamber can be covered with a layer of tar and the boiler does not have an adequate efficiency.
We remove the tar in combustion chamber once a week by burning with ajar feeding door
and chimney flap. If there is a lot of ash in the feeding chamber it is necessary to remove it. The
ash and dust in the combustion chamber should be removed regularly every 3-5 days.
Tubes of the heat exchanger should be cleaned once a month. Before cleaning the heat exchanger
it is necessary to remove cover of heat exchanger thereby creating access to the tube heat
exchanger. The heat exchanger tubes are to be cleaned with a special brush.
Cleaning the air inlet:
Clean air conduit of primary and secondary air is an essential condition for efficient combustion
in the boiler. It is recommended to clean the air conduit minimally once per heating season.
