INSTALLATION AND OPERATION MANUAL
Fallen soot and residues should be swept through the bottom inspection aperture 6 (Fig. 3). After finishing of cleaning, place
the turbulence plates into the initial positions and seal all lids.
Clean the smoke exhaust chamber 26 (Fig. 1). Check the primary air supply channels 30 (Fig. 1) against clogging. For this
purpose, remove the front side panel as shown in Fig. 14 and release the channels lids 6 (Fig. 1).
Control water pressure in the heating system at least once every two weeks. If the pressure drops,
raise it by filling up the system with more water. If the boiler is not being heated for a longer time, drain the
water out of the system when air temperature is below 0°C!
• EMERGENCY SHUT DOWN OF THE BOILER
If for some reason you must immediately shut down the operating boiler, by any means do not pour water on the kindling
wood! The boiler can burst!
It is very convenient to use dry sand for emergency extinction. There should be ~50kg of dry sand in the boiler room. Sand
not only isolates burning firewood well from the air oxygen but also cools down the burning zone. Then, when the boiler
cools down, sand can be easily cleaned and removed.
8. POSSIBLE FAULTS
Fault
Cause
Problem solution
1. The set
temperature
cannot be reached
Not enough water in the heating system
Fill up
Too low temperature of the return water
Raise the return water temperature
Thermoregulator or ventilator is defective
Repair or replace
Poor quality fuel: high moisture content,
too large pieces of firewood
Use dry fuel, split firewood
Heating surfaces of the boiler are very dirty
Clean
No draught in the chimney due to accumulated impurities Clean
The ceramic burner is congested
Clean
Ventilator damper is stuck
Move or clean
2. Smoke escapes
through the boiler
door
The door-sealing rope is damaged
Replace with a new one
Door is not tight along the entire perimeter
Adjust hinge supports and door lock (regulated
screwing or unscrewing of door hinge or lock
screws) (see Fig. 15).
No draught in the chimney due to accumulated impurities Clean
3. Ventilator is not
operating
Emergency thermostat has tripped, light of the
ventilator switch is off
Unsrew the thermostat 1 (Fig. 10) cover and press
the button under it. It is absolutely required to
define and remove the causes of tripping of this
thermostat in order to avoid hazards to property and
human health!
Electronic regulator KR-4.4 or ventilator is faulty
Replace
Power supply failure
Check electric fuses of the electric panel of the
building; call electrician
Lamp 4 lights up (Fig. 11, see technical description of
regulator KR- 4.4)
All firewood has burned. Load more firewood, kindle
the boiler
