Flammable Vapor/Simulative Resistance Device Testing
Step 1. Position power switch on gas control
to the "OFF" position.
Step 2. Disconnect flammable vapor sensor
from gas control.
Step 3. Using a multi-meter set to the ohms
setting, check resistance of
flammable vapor sensor. Resistance
must be between 3,000 ohms and
48,000 ohms. If outside of this range
replace Flammable Vapor Sensor or
Simulated Resistive Device.
CAUTION
DO NOT use a standard multi-meter probe for this
test. Doing so will damage connector. Use
special pin type electronic probes or small
diameter wire pins inserted into connector.
