Checking Functioning - Tecnoinox FR35G/0 Manual De Instrucciones

Operation is permitted with the thermal capacity
deriving from the use of the correct nozzles and, of
course, according to mains pressure, observing the
following:
L.P.G.
Operation is permitted for mains pressure rang-
ing between 20-25 and 35-45 mbar.
Operation is not permitted with mains pressure
below 20-25 and 35-45 mbar.
If mains pressure on the installation site deviates
from the above values or is not within the above pres-
sure range, advise the installers and do not turn the
unit on until the cause has been found and remedied.
NATURAL GAS H
Operation is permitted for mains pressure rang-
ing between 17 and 25 mbar.
Operation is not permitted with mains pressure
below 17 and above 25 mbar.
Before the unit is delivered to the user the follow-
ing checks must be made.
Thermal capacity
Checking thermal capacity entails the following:
• to see if the type and group of gas where the unit
is to be used is the same as that given on the supple-
mentary plate. If it is not the unit must either be
converted or adapted. In this case please refer to
the paragraph: "Conversion or Adaptation".
• to see that the right nozzles have been installed.
To help you, refer to the nozzle table and check
that they are the same as those installed on the
unit.
• an additional check of thermal capacity which
entails seeing how much gas is consumed with the
volumetric method: start the burner and after ap-
proximately 10 minutes (steady state condition) see
if the flow of gas read (in m
sponds to that given in the nozzle table.

If mains pressure on the installation site deviates
from the above values or is not within the above pres-
sure range, advise the gas board and do not turn the
unit on until the cause has been found and remedied.
Read mains pressure with a gauge, e.g. a "U"
gauge (with a minimum 0.1 mbar definition), on the
pressure outlet located on the unit's inlet ramp.
The pressure inlet is placed near a tap and is
accessible after having removed the control panel (see
fig.1).
• Remove the screw from the pressure inlet and con-
nect the gauge's rubber pipe.
• Turn the unit on following the attached instructions
and see if the pressure is within the permitted pres-
sure range.
• Disconnect the gauge
• Put the screw back and look for any leaks, reas-
semble the control panel.
Appearance of the flame and primary
air flow
The flame should be blue and there must be no
points of yellow in it; it must be stable at its base. If
the colour of the flame tends towards yellow it means
the primary air flow is not adjusted properly. If the
primary air flow is too fast the flame will be short and
tend to come away from the burner. The distance "h"
recommended for primary air is shown on the nozzle
table (See Fig. 5).
The appearance of the flame must also be checked
after about 15 minutes of running at full power. The
flame must remain stable even when passing quickly
from minimum to maximum.
Instructions for user
The user must be instructed as to the proper use
and functions. Also 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 functioning of the unit must be checked
again.
It is advisable for the user to stipulate a mainte-
nance contract with the customer assistance service.
When these have been done, test the unit for leaks.
