Power of the boiler (temperature of a heat carrier) is controlled automatically by a

thermo-regulator, by turning on or off a ventilator (ventilators) of the air inlet into

combustion chambers; and by a traction regulator, by closing or opening air supply

opening cap of the ventilator.

Long load combustion period.

Complete fuel combustion ensures cost-efficient fuel exploitation.

Ashes might be removed only 1-2 times per week.

3. TRANSPORTATION, STORAGE, UNPACKING, PREPARATION TO EXPLOITATION

Heating boiler should be carefully loaded, unloaded and transported, suffering no big

impacts. The boiler can be transported only in a vertical position, fastened in order to avoid sliding and

falling. If the boiler is transported in other than vertical position, decorative surfaces may be damaged,

tins battered, control and regulation equipment broken, built-in ceramic kindling details may fall down

and splinter.

The boiler should be stored also in a vertical position. It is not allowed to put one boiler on

another, as a safety-packaging frame is not designed for this purpose. The boiler should be stored in

closed space protected from atmospheric precipitations. Air humidity of the room should not exceed

80% in order to avoid condensate (dew) forming on the surfaces of the boiler. Storage temperature may

vary from -40 ºC to +60 ºC.

If the boiler was transported or stored in minus temperatures, then before it is kindled, it

should be kept in plus temperature no less than for 2 hours (for the order and requirements of the first

kindling see section 6 of this passport).

After the heating boiler is delivered to the site, take off the packing frame and polyethylene

film and unscrew bolts of boiler fastening to the packaging base. Take off the boiler from the packaging

base.

WARNING! Opening the doors of the boiler, check, if all tools listed in the section "THE

BOILER KIT" are there. Check, if painted surfaces haven't been damaged, components – not battered,

control and regulation equipment – not broken during transportation.

If notice any inadequacies of the listed above, lay your claims to the transportation or vendor company.

The kit consists of:

1. Boiler

2. Poker

3. Scraper

4. Guidebook for exploitation

6. Leg

7. Fan/ventilator

These boilers of solid fuel are boilers of complete loading. For this reason they reach the

highest effectiveness when they are working at the nominal power and due to this the boilers must be

equipped with the accumulation tank of sufficient size which could accumulate the excessive heat

volume.

Recommended capacity of the accumulation tank is about 50 liters for 1 kW of nominal

power of boiler:

The boiler has to be exploited only with the installed emergency cooling system.

Description of the connection scheme of the emergency cooling serpentine.

Thermostatic safety valve protects the boiler form the overheating. If the water temperature in the

boiler exceeds 95

C the valve automatically opens the flow of water from the water supply system

through the cooling serpentine . This water absorbs the excessive heat energy and flows out. Sensor of

valve with the external thread ½" is screwed in the socket on the rear wall of the boiler.
