If boiler operates at the power less than the nominal power specified in the
technical specifications, efficiency of the boiler reduces, environmental
indices become worse. Therefore it is recommended to use boiler connection
diagrams with accumulation capacities (
see fig. 4c, 4d
). Minimum volume of
accumulation capacity is calculated according to the formula given at
fig.
4d
.
6.4. Burning chamber assembly
Boilers are supplied fully assembled, but after completion of all boiler
installation works it is necessary to check whether heat-proof concrete bricks
are put in correctly (
18
) (
see. fig.1
) in the burning chamber (
13
). If bricks are
out of their original positions, return them back to correct places. If the bricks
are supplied separately or if you want to replace the worn bricks, do this in the
following sequence:
Through front door (
22
and
24
) into secondary combustion chamber (
13
)
insert the side and the central bricks (
D
) (
see fig.5
). Place rear bricks (
C
) and
bottom bricks (
B
) into the spaces. Lastly, put frontal bricks
(A)
onto the side
and the central brick edges (recess down, towards inside of combustion
chamber).

6.5. Inserting the draught regulator
Attention!
Draught adjuster (28) (see fig.1) is supplied screwed into the
boiler but not sealed.
Draught regulator (
hereinafter referred to as regulator
) is screwed in, for
sealing using oakum or sealing tape. Connect the chain with primary air
supply valves (
24
) (
see also chapter 7.3
).
6.6. Connection of cooling system for boiler
According to the requirements of LST EN 303-5 standard par. 4.1.5.11.3,
for boiler operation it is necessary to install the devices used for
dissemination of heat excess, is for some reasons normal heat take-away is
