NOTES
• The TECNO 34-L & 44-L burners have been type-approved for intermittent operation. This means they should compulsorily be stopped at
least once every 24 hours to enable the control box to perform checks of its own efficiency at start-up. Normally the boiler's limit thermostat
pressure switch TL ensures the stopping of the burner. If this is not the case, it is necessary to apply in series with IN a timer switch that
turns off the burner at least once every twenty-four hours.
• The burners TECNO 34-L & 44-L leave the factory ready for two-stage functioning and must therefore be connected to the thermostat/pres-
sure switch TR. Alternatively, if single stage operation is required, instead of thermostat/pressure switch TR install a jumper lead between
terminals T6 and T8 of plug X4.
ATTENTION:
- Do not invert the neutral with the phase wire in the electricity supply line. Any inversion would cause a lockout due
to firing failure.
- Only use original spare parts to replace the components.

NOTES
Electrical wiring must be made in accordance with
the regulations currently in force in the country of
destination and by qualified personnel.
Riello S.p.A. declines all liability for modifications or
connections other than those shown on these dia-
grams.
Use flexible cables according to standard EN 60 335-1.
All the cables to be connected to the burner are fed
through the grommets.
The use of the grommets can take various forms; by
way of example we indicate the following mode:
7 pole socket for single phase power supply, ther-
mostat/pressure switch TL
4 pole socket, thermostat/pressure switch TR
5 pole socket
2 pole socket for remote control box reset accessory
Housing for the nozzles
(Drill if 5A nozzles are required)
