N.F.P.A. now requires 4 heat sensors and one instruction label per ladder section. Each heat. sensor has an expiration date printed on them. Any expired labels must be replaced. Place 2 heat. sensor labels below the 2nd rung from the top of each section (1 on the right rail - 1 on the left. side) inside the rail.
The heater will bring the sensor up to operating temperature within 20 to 60 seconds depending on the sensor, and also keep the oxygen sensor hot even when the engine is idling for a long period of time. Heated O2 sensors typically have two, three or four wires (the extra wires are for the heater circuit).
