8. Combustion products forced draw-off mechanism
The boiler can be equipped with a flue ventilator (only OSV hereinafter) which enables to install
boiler also in the space where it cannot be connected to a chimney and combustion products can be
led away into the outdoor space through the wall– according to TPG G 800 01 „Flue outfall from the
gas fuel appliances on the exterior wall (façade)
This complementary equipment can be used in the whole output range of boilers designated for natural gas
combustion. Two-sectional boilers can only be operated with rated output. OSV is offered in three sizes for
outputs according to the table as follows:

The operation safety is ensured by a differential pressure switch which switches on the burner only
on condition of a proper exhaustion. Other safety element watching the combustion products escape
into the boiler room is the combustion products return flow TS fuse which is belongs to boilers
standard equipment.
