Technical data
Gas connection
Prior to connecting the unit to the gas mains, check
the data plate to see if the unit has been set and tested
for the type of gas available.
If the gas type given on the data plate is not the
same as that available, please refer to the paragraph
“Conversion or Adaptation”.
Connect up to the gas mains using metal pipes
with a suitable diameter; install an approved cutoff
cock between them.
If flexible pipes are used they must be in stainless
steel according to the standard in force.
The connection ramp on the unit complies with the
ISO 7-1 standard, and the thread is external. TThe
connection is located at the rear or at the bottom
depending on the model.
Only an authorized firm may connect the unit.
Once the unit has been installed, use operating
pressure to check for leaks on the fittings; foamy sub-
stances would be ideal for this purpose as they do not
cause corrosion, e.g. a leak finder spray.
Note:
When checking for leaks do not use bare
flames!
