For the Installer
2.6.3 Storage room and/or feed system in unheated non-living areas
(e.g. attic)
If the temperature difference between the boiler installation room, suction turbine, changeover unit, hoses and
storage room is greater than 20 °C, they must be routed as shown in the sketch, Fig. 19. In this case, only 2 suc-
tion probes may be connected as the 3rd connection is the idle position. This 3rd connection must be tightly
sealed to prevent cold air from circulating in the hoses and condensation forming inside them.
The configuration of the entire system must comply with technical fire protection requirements in accor-
dance with the applicable regulations, standards and guidelines.
