6.4 WHAT TO DO IF THE UNIT IS NOT GOING TO BE USED FOR A LONG TIME
Turn the gas shut-off cock installed upstream of the appliance off. Clean the unit thoroughly following the
instructions and dry it carefully.
6.5 MALFUNCTIONS
In any case, if you suspect the presence of anom-
alies, ALWAYS CLOSE the gas shut-off cock and
inform the authorized aftersales service.
Unauthorized persons should never attempt to
repair the appliance, or carry out maintenance.
Tampering with the appliance voids the warranty!
6.6 OPERATIONAL CHECKS
Before the unit is delivered to the user the fol-
lowing checks must be carried out:
THERMAL CAPACITY:
Check that the pressure and
type of gas supplied where the unit is to be used
is the same as that indicated on the plate. If it is
not, the unit must either be converted or adapted.
In this case please refer to the paragraph: “Conver-
sion or Adaptation”. Check that the right nozzles
have been installed. Refer to the nozzle table and
check that the nozzles indicated in the table are the
same as those installed on the unit. An additional
check of thermal capacity entails verifying the gas
consumed with the volumetric method: light the
burner and after approximately 10 minutes (oper-
ating conditions) check that the gas fl ow (in m
3
/h
or in kg/h) corresponds to that indicated in nozzle
table.
APPEARANCE OF THE FLAME AND PRIMARY AIR-
FLOW:
The fl ame should be blue and there should
be no yellow dots in it; it must be stable at its base.
If the colour of the fl ame tends towards yellow it
means the primary airfl ow is not adjusted proper-
ly. If the primary airfl ow is too fast the fl ame will
be short and tend to burn above the burner. The
appearance of the fl ame must also be checked
15 minutes after the appliance has been running
at full power. The fl ame must remain stable even
when passing quickly from minimum to maximum.
USER’S INSTRUCTIONS:
The user must be trained
on the correct use and functions of the appliance.
We would like to point out that any alterations
made to the room where the unit is installed could
infl uence the amount of air used for combustion
and for this reason the function of the unit must
be checked again. When these checks have been
done, test the unit for leaks.
