And to change the design so you need a thermocouple.. and so the pilot will be shut off if it goes out.. YOu MUST change teh control valve
That and the Thermocouple (S) are the entire job.
For those who do not know how thermocouples work.....
They generate a voltage when hot, this voltage is applied to either a solid state device or to a magnet (causing current to flow) depending on the appliance,
The magnet is not strong enough to pull itself in (The button you push does that) but it is strong enough to hold.
There is now way a THERMOCOUPLE can fail allowing gas to flow. Absolutly nonn. Can not happen.
However the control valve CAN fail dangerous.
