Operational Checks; Thermal Capacity; Replacing Parts - Tecnoinox FTR70G7 Manual

Malfunctions are not always caused by the quality of the components
used. These appliances are manufactured using top quality
components. Failures may be caused by 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 m3/h or in kg/h) corresponds to that in the nozzle table.
APPEARANCE OF THE FLAME AND PRIMARY AIRFLOW
Use the inspection hole ( Ref. "I" fig.2) to check the flame.
Faulty parts should only be replaced by qualified personnel.
Disconnect the appliance from the gas distribution network before
doing any work.
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.
Malfunctions
In any case, if you suspect the presence of anomalies close the gas
shut-off cock and inform the authorised after-sales service.

Operational checks

The flame should be blue and there must be no dots of yellow 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 primary air capacity is fixed, therefore no regulation is required.
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 function of the unit must
be checked again. When these checks have been done, test the unit
for leaks.
