MEGAPREX N 720N ÷ 1060N

7.2 First ignition

After successfully completing the checks indicated in the previous paragraph, the burner may be ignited for the first time. This must be done by a
technician authorized by the manufacturer of the burner. The technician will be fully responsible for the field of calibration within the declared and
approved output range of the boiler. After opening the fuel on-off cocks and checking that there are no leaks in the supply line, place all switches
in the ON position. The burner is now ready for first ignition, and for the adjustments that may only be made by the authorized technician.
On first ignition, check that the door, burner flange and connections to the chimney are tight, and that there's a slight negative pressure at
the base of the flue. The fuel rate must match the information on the boiler's rating card. Under no circumstances may it exceed the declared
maximum rated output value. The temperature of the flue gas must never fall below 160ºC.

7.3 Shutting down the boiler

- Set the operating thermostat to the minimum value.
- Turn off the power to the burner and cut off the fuel supply.
- Let the pumps operate until they are stopped by the temperature controller.
- Disconnect the power to the electrical panel.

MAINTENANCE

8.1 General instructions

Periodic maintenance is essential for the safety, efficiency, and long life of the appliance.
All operations must be carried out by qualified personnel. Before performing any cleaning or maintenance operations, the fuel supply must be
cut off after first shutting off the power.
For proper boiler operation and maximum efficiency, the combustion chamber, fire tubes and smokebox must be cleaned regularly.

8.2 Routine maintenance

Maintenance must be scheduled based on the fuel used, number of ignitions, system characteristics, etc. Maintenance intervals can therefore
not be determined in advance.
As a reference, we recommend the following cleaning intervals, depending on the fuel:
- Gas boilers: Once a year
- Gas oil boilers: Twice a year
In any case, local maintenance standards must be observed.
During routine maintenance, remove the turbulators and then brush the tube bundle and furnace. Remove the deposits accumulated in the
smokebox through the open inspection doors. For more thorough cleaning, remove the rear smokebox. If worn, replace the flue gas seal. Check
that the condensate drain is not blocked. Make sure the control and measurement devices on the boiler are working correctly.
On this occasion, record the amount of top-off water used. After analyzing the water, perform a preventive descaling.
After repeated refills, the calcium and magnesium salts dissolved in the water will produce deposits in the boiler, cause the metal plates to
overheat, and can cause damage that is not attributable to materials or workmanship, and is therefore not covered by the warranty. After
performing cleaning and maintenance operations and the next ignition, check the tightness of the door and smokebox. In the event of combustion
gas leaks, replace the corresponding gasket.
The operations performed must be recorded in the system logbook.

8.3 Special maintenance

Special maintenance must be carried out at the end of the season or for extended shutdowns.
All of the operations described in the previous section must be performed, in addition to the following:
- Check the condition of the turbulators for wear.
- After cleaning the flue gas circuit, wipe with a rag dipped in a diluted caustic soda solution. After letting it dry, wipe all surfaces with a rag
dipped in oil.
- Hygroscopic substances (quicklime, silica gel in small containers) should be placed inside the furnace, which must then be closed hermetically
so air cannot enter.
- Do not empty the system or boiler.
- Protect the screws, nuts and pins on the door with graphite grease.
The operations performed must be recorded in the maintenance logbook.
