Basic elements of the boiler construction a
(User | Installer)
The appearance and construction of the boiler are shown in the technical drawing. Some parts of the boiler are
numbered in the drawing.
There are four doors on the front wall of the boiler:

Cleaning door (1) for access to cleaning and observation of the boiler convection channels.

Loading door (2) required for filling the boiler with firewood, cleaning and observation of the combustion
chamber. An air damper (17) is built into the door.

The grate door (3) and the pre-grate door ( 20) allow the arrangement and ignition of the ignition layer,
scaffolding , cleaning and observation of the combustion chamber and the condition of the cast iron
grate (19).

Ash pan door (4) for removing the ash drawer (21) and cleaning the ash pan. The door has a built-in
hinged hatch (16), which regulates the supply of primary air for fuel combustion. The tailgate can be
raised or lowered using the built-in knob.

The pull rod (5) is used to close and open the smoke exhaust flap (13), the loading chamber during fuel
addition to the boiler. When opened, the flap allows the exhaust gas to be discharged along a shorter
path to the chimney. The hatch must be closed when the boiler is in operation.
On the rear wall of the boiler there are:
 Connection (10) with ¾ ”female thread for filling and draining water from the boiler.

A stub pipe (12) with a 1½ ”internal thread, which is a return stu
b pipe for water from the central heating
system

Secondary air intake (9), where the air needed for complete combustion of the fuel is sucked through 6
openings. The amount of air can be adjusted with the shifts (18).

Flue with a hatch (8).

The exhaust fan (7) mounted with an adapter to the rear vertical wall of the flue. The fan creates the
draft needed to burn fuel and is an essential equipment of this boiler.
On the upper wall of the boiler there are:

The stub pipe (11) with a 1½ "internal thread is the
stub pipe that supplies hot water to all heat receivers
connected to the boiler.

Sleeves (22) and (23), in which the boiler temperature sensor and the STB sensor are placed.

Boiler operation controller (26) - a detailed description can be found in the controller documentation
supplied with the boiler.
There are plugs on the left and right walls of the boiler, which allow access to the protection (24) of the ceramic
duct. The protection should be removed if the duct plates need to be replaced.
