Kindling order of the boiler

Before kindling the boiler, check whether all requirements indicated in the section 1 are

executed.

Open the damper of the upper flue (C) by pushing the handle (12) towards yourself (see fig. 2).

Open the door (9) of the upper combustion chamber (2) and put dry kindling wood on the heat-

resistant shell (3) to form 2-3 cm gap between the opening of the shell and kindling wood. Put some

of the easy flammable materials and bigger kindling wood and firewood atop. Fire the kindling

wood, wait till the firewood combusts, close the door and turn the handle (12) of the flue damper

from yourself to the end. Load the wood without any bigger spaces until the top of combustion

chamber. Bigger pieces of firewood should be loaded in the middle and smaller prices – at

the sides, because the walls of the combustion chamber due to their lower temperature

slows down the combustion of the bigger pieces of wood. Do not cover with the wood the hole

of the smoke extraction valve C . With the boiler control panel switch the tension of the electronic

controller with the button „0"-„I" ( see the technical description of the electronic controller). There

will be switched on the lights and temperature indicator. Using the buttons of the temperature

regulation set required temperature of the water flowing of the boiler – it is recommended to set on

the 70

pieces ., Leave the lower door open until the water temperature in the boiler reaches 40

the lower door, close the valve of the upper smoke traction by pushing the handle of valve (12) to

the end. Switch-on the ventilator with the control panel.

automatic range and will maintain the set temperature of the water from the boiler.

WARNING! The door of the boiler combustion chambers should be tightly closed, there

should be no flammable products accessing the exterior. Door tightness is regulated by screwing or

unscrewing hinge and lock screws of the door.

Regulation of the boiler temperature – see the technical description of the electronic

regulator.

Emergency thermostat of the water temperature (safety switch ! 95

If the water temperature due to the unforeseen reasons exceeds the maximal allowable limit ,

safety thermostat (emergency switch), switches off the ventilator of the air supply. Combustion

intensity will decrease and the temperature of water will drop.

When the emergency thermostat comes into action (switches off) – the light of the ventilator switch

and electronic controller is off , it is necessary to detect the reasons and to remove them.

Emergency thermostat is turned on by taking off the cover of thermostat ! 108

red button. .

The attempts of purchaser to repair the thermostat and to recover its functions on his own without

removal of reasons which caused the over-heating of boiler can result not only serious damages of

boiler, but also the danger for the health and life. If the reasons of the switch of the emergency

thermostat can not be detected and removed, it is necessary to call the servicing company !

Addition of the firewood

While putting firewood into the combustion chamber (during boiler operation or after load

burning off), keep strictly to the set order:

1) Open the damper of the upper flue by pulling the handle (12) (see fig. No. 2).

2) Switch off the ventilator.

3) Wait at least 20 s, open the upper door.

4) Put the firewood in and close the door tightly.

5) Switch on the ventilator.

6) Close the damper.

If operated following this order, smoke and carbon won't enter the room.

Combustion control

The combustion control of boiler is described in the chapter "COMBUSTION CIONTROL"

of the technical description of regulator KR-4.

The flame in the boiler can be checked by opening the lower door of the combustion

chamber when the ventilator is on.

Temperature regulation of the heating system – See the description of the scheme

of boiler room ( beginning of the chapter 4).

Cleaning of the boiler

Aches are removed from the boiler each 4-7 days. Open the door of the upper combustion

chamber and shovel aches down to the lower chamber. Open the door of the lower chamber, take out

the ceramic inserts and shovel ashes to the metal box.

WARNING! In any case keep strictly to the determined order: open the damper of the

upper flue, then after 20 s open the boiler door.

Afterwards the boiler will work on the
