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
5.3 Heating up for the first time
NOTICE
Optimum efficiency and efficient, low-emission operation can only be guaranteed
if the system is set up by trained professionals and the standard factory settings
are observed.
Take the following precautions:
❒ Initial startup should be carried out with an authorised installer or with Froling
customer services
The customer is responsible for ensuring the following prior to initial start-up of the
system by Froling customer services:
▪ Electrical installation
▪ Installation of water pipes
▪ Flue gas connection including all insulation work
▪ Work must comply with local fire protection regulations
▪ The operator must ensure that at least 50% of the boiler's rated heat output can be
extracted from the network on commissioning.
▪ The necessary "dry run" of the system means that the discharge system must be
empty at the start of initial startup. Fuel must be available, however, so that the
discharge system can be filled once the system is released.
▪ When heating up the boiler for the first time to dry out the fireclay concrete, the
customer must provide approx. 1 m³ of dry firewood.
▪ It is essential that the electrician who has carried out the installation work is availa‐
ble when starting up the system for the first time to make any changes to the wir‐
ing which may become necessary.
