WIRING - FLAME ROD

For proper operation of flame rectification systems, it is necessary to maintain at least 20 megohms insulat-
ing resistance in the flame rectification circuit.
1. The scanner should be wired using metal cable or rigid conduit.
High voltage wiring must not be installed in the same conduit with scanner wiring.
2.
Selection of Scanner Wire
Use #14, 16, or 18 gauge wire with 90 C, 600 volt insulation for up to 20 feet distance.
1.
2. The type of insulation used with flame rectification is important, since it must protect against current
leakage resistance to ground. Use Belden 8254-RG62 Coaxial Cable (or equal) for runs greater than 20
feet. Maximum wiring run not to exceed 100 feet.

MAINTENANCE - FLAME ROD

Type 69ND1 Flame Rod
The flame rod and its insulator should be kept clean by washing routinely with soap and water. Rods should
be routinely replaced as they oxidize.
Flame Signal Strength
Routine observation of the flame signal strength will forewarn any deterioration in the capability of the
flame detector or its application.
