type
UV detector C7027A, C7035A, C7044A
Flame rod Flame rod or rectifying optical sensors,
C7012A,G (UV) or IRD1020.1 (IR)
* When using a flame rod, the current on the flame jack plug is inverted. See also Fig 4-2.
Flame detector leads are colour coded. The blue lead wire must be connected to the F terminal (T23) and the
white lead wire to the G terminal (T24). The UV sensing tube is polarity sensitive. Reversing the lead wires
even momentarily will destroy the UV sensing tube.
