1.0 General
1.1 Application
Appliance type GS+ is solely suitable for the free and direct intake of the air to be heated and the
free discharge of heated air into the room. Appliance type G+ with a centrifugal fan is suitable both
for the free and direct intake of the air to be heated and the free discharge of heated air into the
room, and for connection to a duct system.
If areas are to be heated in which corrosive vapours are present (chlorinated hydrocarbons in
particular), which are either produced directly in the area, or which may be drawn in from the
outside by the heater via a duct or an open connection, wall air heaters cannot be used because of
the risk of corrosion to the heat exchanger.
