The fan of the CO
2
set sucks in the flue gases from the boiler chimney as well as clean air from the boiler house. A 2-way valve
is integrated in the T-piece and modulates the ratio of flue gas and clean air, to control the temperature of the CO
2
gas that is
transported to the greenhouse.
The air mixture is transported to the greenhouse via the air outlet on the fan housing. The fan housing can be mounted in
different configurations to better align with the inlet of the greenhouse distribution system (see §
3.9

for more information).
