Connector length and location
The length of the fill connector is subject to the distance from the return
air connector. Connectors may be spaced out < 500 mm if both con-
nectors are set into a cellar window.

PYROTEC
If connectors must be located on the long side of the storage room, we
recommend alternating the filling between the connectors. This
ensures more efficient filling. In any case both connectors should be
earthed. A deflector should be installed opposite both connectors.
Internal pellet storage room
If the fill and return air connectors must be routed through an adjacent
room, clad both with a fire-resistant material compliant with class F 90
(rockwool, or similar). Earth each extension piece via pipe clips. Plastic
pipes should not be used as extension pieces.
