Flame Sensor
Two types can be used on a Winnox Burner:
• Flame rod
• UV scanner
Flame rods are available for all Winnox burner sizes. Further
information can be found in:

A UV scanner can be used on all Winnox burner sizes. Further
information can be found in:
• Info Guide 852; 90° UV scanner
• Info Guide 854; straight UV scanner
• Info Guide 856; self-check UV scanner
Flame Monitoring Control
The flame monitoring control processes the signal from the flame
rod, or UV scanner, and controls the start-up sequence and the
main gas shut-off valve sequence.
Eclipse recommends the use of flame monitoring control systems
which maintain a spark for the entire trail for ignition time when
using UV scanners.
Some of these flame monitoring models are:
• Veri-flame; see Bulletin/Info Guide 610, 620, 630
• Bi-flame series; see Instruction Manual 826
• Multi-flame series 6000; see Instruction Manual 820
DO NOT USE the following:
• Flame monitoring relays which interrupt the trial for ignition
when the flame is detected
• Flame sensors which supply a weak signal
• Flame monitoring relays with low sensitivity
