MERCURY FLAME SENSORS

Prevent Gas Flow to Main Burner if Pilot Flame is Not Burning or Is

Insufficient to Properly Ignite Main Burner

FEATURES

• These sensors combine a rugged Snap-Action switch and powerful mercury

  actuated thermal element.

• May be used with natural, manufactured or mixed gases and with LP gases where

  means are provided for obtaining automatic pilot gas shut-off.

• Switch may be conveniently mounted in any position.

• Cover is easily removed, making switch terminals readily accessible.

• No button to depress – Sensors are recycling type which require relighting or

  possible restoration of proper gas pressure to return to operation.
