Electrical connection.

Electrical installations must be carriedout according to standard NF C 15.100 and other standards currently in force.Particular attention must be paid to theburner supply main disconnect switch which must be able to carry the total circuit output and isolate the circuit during maintenance.

Output adjustment.

Operation. All the heat energy is providedthrough a single flow. The flow can be adjusted from “full”to “off” and vice versa: the industrial burner ignites and goes out according to heat requirements.

?

1-stage burner. Two thermal output flows areavailable.These can be adjusted to:-Full” or “off”: when outputincreases, it moves progressively through two levels to avoid impact on a sudden startup.-“Full” or “low”: a low flow is usedwhen there is little demand for heating, or for domestic hot water supply. The combustion gases are professional cooler and increase with theoutput. In the interests of safety, an isolatingtransformer and a 30mA differential circuit breaker should be used when thesupply has no neutral or has neutralimpedance. This circuit must be protected using a 6.3A delayed action fuse. The smallest conductor section must measure 1.5mm

2-stages burner.

Setting connection.

1-stage and 2-stages burners:7-pole plug.Connect the industrial thermostat or pressure governor between terminals T1 and T2.2-stages burners:4-pole plug. -Connect terminals T6 and T8 for “full”flow or “off”.-Connect the two-way contact devicesto terminals T6, T7 and T8 for “full” or “low” flows controlled by a thermostat or pressure switch manufacturers. Power supply suppliers connection: (see diagram below).The power supply is connected betweenterminals N (neutral) and L1 (live on 7- pole plug). Establish a series connection between the manually-activated safety thermostat (or pressure switch) and the phasepower supply.
