4.6 Caution - gas connection
•Improper connection of gas supply can cause fire and/or explosions. The gas
supply should be installed, adjusted, and tested by a qualified gas installer.
4.7 Caution - heat
•The piping from and to the coffee roaster can reach high temperatures just like
the coffee roaster. It is up to the user to make the provision so that the pipes can
not be touched and/or to apply the clearly visible warning.
•Surfaces of the coffee roaster can become very hot during operation. Contact
with hot surfaces causes severe burns.
