2. Boiler houses with a heat output of more than 25 kW shall additionally meet the following requirements:

the distance of the boiler furthest from the chimney, with gravitational draught, must not exceed 50 cm
of the chimney height;

fuel storage and slag storage should be located next to the boiler hall at a storage height of up to 220 cm
with a free space above the fuel of at least 50 cm;

facilities and equipment should be provided for the vertical and horizontal transport of fuel and cinders;

the fuel storage room should be ventilated in a natural unforced manner allowing for one full air change
per hour in the fuel storage room and three full air changes in the slag storage room;

the entrance door to the boiler room shall be non-combustible (class 0.5 fire resistance), minimum width
80 cm, opening outwards; it shall have a handleless locking system enabling the door to be opened
outwards under pressure and inwards using a handle;

ventilation requirements are the same as for boiler rooms of smaller capacity; additionally, in boiler
rooms whose capacity exceeds 400 kW, in addition to supply and exhaust ventilation, there should be
mechanical ventilation, periodically activated when filling in fuel and slagging the boilers, ensuring a
minimum of 10 full air changes per hour;

natural lighting should be provided in the boiler room, illuminating the boiler from the front, and the
window area should be at least 1/15 of the boiler room floor area; half of the installed windows should
be openable; electric lighting and an electric socket with a voltage not exceeding 24 V should also be
located in the room;

there should be a drainage sump in the floor to allow water cooling, and its capacity should be equal to
the water capacity of the largest boiler, but not more than 2 m

;

in the boiler room, thermal pipes should be insulated;

boiler location with minimum required distances is shown in the boiler room diagram below.
ATTENTION!
Mechanical exhaust ventilation should not be used in a boiler room.
ATTENTION!
Ensuring a sufficient supply of fresh air into the boiler room will enable efficient
combustion of the fuel.
