"Drop Out" = Time until the gas is cut off after flame failure.
Sensing voltage varies depending on gas type. (Refer to combustion specifications)
Overheat Switches
If the air filter or air outlet becomes blocked, the overheat switch causes the solenoid valve to close
and operation to stop. The appliance can be re-lit when it has cooled. If the air filter or outlet
becomes blocked and the OHS fails, the thermal fuse will "blow", causing the solenoid valve to close
and operation to stop. This is a "one-shot" fuse; therefore the appliance cannot be restarted until this
fuse has been replaced.

Tilt Switch Safety Device
Normally, the tilt circuit is open, but the steel ball rolls when the unit is tilted, closing the circuit.
