APPENDIX
Electrical wiring
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:
1- 7 pole socket for single phase power supply, ther-
mostat/pressure switch TL
2 - 2A Housing for the nozzles
(Drill if 2A nozzles are required)
• The RL 34/1 MZ 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.
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.
