NOTICE
For fuels with a water content < W30 the boiler's rated heat output can only be
guaranteed if it is used with a flue gas recirculation system (FGR).
Miscanthus
Switchgrass or elephant grass (Latin name: miscanthus) is a C4 plant. Standards and
regulations for burning these plants have not been standardised, so the following ap‐
plies:
NOTICE! The regional regulations for burning miscanthus should be observed. Opera‐
tion may only be possible by special permit.
Changing the fuel
CAUTION
Incorrect fuel parameter settings:
Incorrect parameter settings have a significant adverse effect on the functioning
of the boiler, and as a result this will invalidate the guarantee.
Therefore:
❒ If the fuel is changed (e.g. from wood chips to pellets), the system must be
reset by Froling customer services.
5.2.2 Non-permitted fuels
The use of fuels not defined in the "Permitted fuels" section, and particularly the burn‐
ing of refuse, is not permitted.
CAUTION
In case of use of non-permitted fuels:
Burning non-permitted fuels increases the cleaning requirements and leads to a
build-up of aggressive sedimentation and condensation, which can damage the
boiler and also invalidates the guarantee. Using non-standard fuels can also lead
to serious problems with combustion.
For this reason, when operating the boiler:
❒ Only use permitted fuels
