The rating factor for each heater model varies depending
on the size of the duct that connects directly to the
heater reduction hood. In general, a larger duct creates
less restriction for the heater and therefore allows a
longer duct system to be used. To check if a duct system
is permissible, each part of the duct system has been
given a component rating which may change depending
on its size and the number of permanently open outlets
on the system.

Danger!
Risk of burning and injuries!
• The hot air ducting must be routed and fastened in
such a way that there is no risk to people, animals
or materials that are sensitive to temperature from
radiation / contact or blown hot air.
• If necessary, cover or protect exposed ducting or
deflect hot air that poses a potential risk.
• The outflow hood must be fitted on the hot air outflow
side.
• High temperatures occur during and after heater
operation. Avoid working in the heater vicinity while
it is in operation. Switch the heater off and allow it
to cool before commencing work. If necessary, wear
safety gloves.
!
Caution!
• The heater air intake must not be positioned in such
a way that any exhaust gases can be drawn directly
into the heater and its ducting system, under normal
circumstances.
• The air intake must be positioned so that the hot air
cannot directly re-circulate back into the heater.
• In the event of overheating, possible local air
temperatures can reach 150°C and surface
temperatures up to 90°C. Use Eberspächer approved
temperature resistant ducting only.
• To prevent overheating, one outlet must be
permanently open and of sufficient cross-sectional
area to allow full heater airflow to pass without
restriction.
