Operational Checks; Replacing Parts - TECNOINOX FRS35G7 Handbuch

Turn the gas shut-off cock installed upstream off. Clean the
appliance with soapy water, rinse, dry carefully and apply a light
layer of liquid paraffin.
Malfunctions do not always depend on the quality of the components
used. These appliances are manufactured using top quality
components. Failures may be caused by voltage surges, or dust and
dirt in the operating components.
Unauthorised persons should never attempt to repair the appliance, or carry out maintenance. Tampering with the appliance
voids the warranty!
Before the unit is delivered to the user the following checks must be
carried out.
THERMAL CAPACITY
Check that the type and group of gas 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: "Conversion 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: start the burner and after
approximately 10 minutes (in working conditions) check that the gas
flow (in m 3 /h or in kg/h) corresponds to that in the nozzle table.
APPEARANCE OF THE FLAME AND PRIMARY AIRFLOW
Use the inspection hole "I" (fig.2) to check the flame.
Only qualified personnel should replace faulty parts. Prior to
commencing any kind of work, disconnect the unit from the gas
distribution network.
After having removed the control panel, all the functional parts of the
appliance are easily accessible
Only order spare parts from the manufacturer or an authorised reseller.
What to do if the unit is not going to be used for a long time

Replacing parts

Malfunctions
In any case, if you suspect the presence of anomalies close the gas
shut-off cock
The flame should be blue and there should be no yellow dots in it; it
must be stable at its base.
If the colour of the flame tends towards yellow, it means the primary
airflow is not adjusted properly. If the primary airflow is too fast the
flame will be short and tend to burn above the burner.
The appearance of the flame must also be checked 15 minutes after
the appliance has been running at full power. The flame 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 influence the amount of air
used for combustion and for this reason the appliance must be
checked again. When these checks have been done, test the unit for
leaks.
