5.5 Connecting the delivery pipe to the sewer network
Fekabox 200, Fekafos 280 and Fekafos 550 tanks have a 2” GAS outlet connection.
To guarantee a perfect seal it is recommended to use Teflon or suitable glues depending on whether the
material being glued is plastic (PP or PVC) or metal.
5.6 Connecting the ventilation pipe
Remember to provide a ventilation pipe to avoid the formation of inflammable, explosive or toxic mixtures.
On the station identify the seat for the ventilation duct, marked with the symbol
. Open the duct as
indicated in point 5.3 and connect the ventilation pipe so that it can evacuate any condensate from the
station. Check that the coupling is watertight.
The various national regulations may require different ratios between the diameter of the outlet pipe and
that of the ventilation pipe. Ensure that the pipe outlet is in the open (for example, above the ridge of the
roof if the station is installed inside a building) and that the exhaust gases cannot get into other places such
as buildings, rooms and similar. Avoid horizontal stretches in the ventilation duct.
5.7 Closing the cover
Check that the gasket of the cover is lying in the bottom of its seat and is not twisted before screwing the
cover onto the tank.
The tank is shipped with the gasket already fitted under the cover.
Check that the gasket does not slip in the thread during screwing. In case of installation inside buildings, the
cover must be screwed right down until the threaded seat appears in the slot shown in the figure, to
guarantee that the station is hermetically sealed against liquids and gas.
Before tightening the cover of the tank, lubricate the thread and O-ring using soapy liquids or lubricants for
plastic pipes/couplings.
To prevent unauthorised opening of the cover, it is recommended to fix it to the station with
the screw and the metal bracket provided. (see fig. 6B).
The screw must be passed through the slot on the outer edge of the cover, and screwed into the seat in the tank.
There are two cylindrical seats on the cover which can be used to facilitate closing of the cover by levering
with suitable tools (see fig. 6A).
