▪ When burning wood briquettes use the settings for extremely dry fuel
▪ Wood briquettes must be heated up with firewood as per EN 14961-5
(at least two layers of firewood under the wood briquettes)
▪ The fuel loading chamber must not be filled more than 3/4 full, as the wood briquettes
expand during combustion
▪ Even when using the settings for dry fuel, burning wood briquettes can cause combus‐
tion problems. In such cases, repairs must be carried out by qualified staff. Please con‐
tact Froling customer services or your installer.
5.2.3 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
5.2.4 Heating up for the first time
CAUTION
If the boiler heats up too quickly on initial start-up:
If the output during the heating-up process is too great, the combustion chamber
may be damaged as a result of drying out too rapidly!
For this reason the following applies the first time you heat up the boiler:
❒ Start the firewood boiler for the first time in accordance with the heating in‐
structions
Heating instructions when starting up a firewood boiler for the first time
❒ Place a piece of wood diagonally across the combustion chamber (see diagram on
left)
➥ Load the boiler with a small amount of firewood (max. 10-20% of the fuel load‐
ing chamber)
➥ Ignite it and allow it to burn slowly with the central pre-heating chamber door
open
