7.4. BURNER REGULATION
Light the burner and keep it burning during a few minutes maximum. Then all at once change from maximum to minimum and
to maximum again several times. When doing these tests, if the burner extinguishes at the minimum position or the flames are
too big, then proceed to regulate the minimum by turning the thermoelectric security valve to the left to obtain a bigger flame or
to the right to obtain a smaller flame.
8. PROBLEMS AND SOLUTIONS.
During normal operation of the device, problems can arise. These problems, as well as the possible causes and solutions are
listed below.
-
The pilot burner and the main burner do not ignite.
Verify the following:
a)
Make sure the stopcock is open.
b)
Check if there is gas in the network.
c)
Dismantle the pressure regulator that supplies gas to the device (in case it exists) and clean the input filter. There
could be an obstruction due to gas impurities.
-
The pilot burner extinguishes easily.
Check if the injector is obstructed.
Clean the injectors with high air pressure only. Never use wires or sharp objects that could vary the diameter of the injectors.
If the pilot burner does not retain the flame once these tests are completed, this means that the thermocouple is too separated
from the flame or the connection to the valve is loose. In this case, tighten, but not excessively to avoid damaging the
thermocouple head.
-
The flame is yellow.
Possible causes are:
a)
The burner is dirty. In this case, clean the burner.
b)
Bad primary air regulation. Follow the instruction given under point 7.3. for regulation of primary air input.
c)
Obstruction in the burner injector. Clean the obstructed injector by blowing air.
For any other type of breakdown, contact our nearest After-sales Technical Service.
9. USE AND MAINTENANCE INSTRUCTIONS
9.1. START-UP.
9.1.1.
SWITCHING ON THE BURNER
a)
Open the stopcock located outside the device.
b)
Put the selector in position pilot burner “*”. To do this, press and simultaneously turn the selector 90º to the left and
light the pilot burner maintaining the selector pushed about 20 sec.
NOTE: It is possible that the first ignation takes more time when the pilot burner gas pipe is filled with air.
c)
To ignite the burner, turn the selector another 90º more to the left until the maximum position. If you continue turning
the selector until the minimum position power will be reduced progressively.
9.1.2.
SWITCHING OFF THE BURNER.
Turn the selector from position “maximum” or “minimum” to position “*” (pilot burner). The burner will be switch off and the
flame of the pilot burner will keep on burning, facilitating thus a future ignition.
If you want to switch off the burner completely, turn the selector to position “O”. At the end of the day, it’s advisable to close the
gas valve of the device.
