Combustion air supply The pressure in the boiler room must not be less than 3 Pa
(0.3 mm H
2
O). The air vents for boiler rooms must have a
clear, net cross-sectional area of at least 200 cm² and must not
be sealable. With combustion boiler systems with a fuel heat
output upwards of 50 kW, the net, clear cross-sectional area
must be increased to at least 5 cm² per kW rated output
according to the combustion air requirement of the boiler
system. The air supply ducting must connect directly to the
outside and if the ducting passes through other rooms, it must
be jacketed to Class F90/REI90. On the outside of the building,
air vents must be covered by a protective grille with a mesh
size of > 5 mm. The supply of combustion air should, if
possible, enter at floor level in order to prevent cooling of the
boiler room.
Electrical installation The lighting and the electrical wiring in the boiler room must be
permanently installed. There must be a clearly marked
emergency off switch in an easily accessible position outside
the boiler room, close to the boiler-room door.
The line connector 230 VAC, 50 Hz, 13 A is needed.
Fire extinguisher A hand-held fire extinguisher (6kg gross weight, EN3) must be
mounted outside the boiler room near the boiler-room door.
Protection against freezing The boiler room, pipes carrying water and any district heating
pipes must be protected against freezing.
