10 Detectors
On ignition, the signal increases. Typical levels are 4 to 40 pA
in sulfur mode, 10 to 70 pA in phosphorus mode. Verify that
the flame is lit by holding a cold, shiny surface, such as a
mirror or chrome- plated wrench, over the vent exit. Steady
condensation indicates that the flame is lit.
