- As you may noticed in #1. for gas to flow it takes two (solenoid)valves to operate.
The main (security)valve which is always needed.
And
one or both of heating power control valves (2kW or 4kW).
All these requires a holding voltage to keep open and at least a pulse of actuating
voltage to open. Those LEDs tells only of holding voltage of heating power control valves,
they do not tell anything about valve actuations.
So, the "clacking sound" tells about opening of one valve. Distinguishing of two valves
to open is needed. Without any electrical measuring you might try to touch those solenoids
to feel if they operate.
There is another way to check gas flow wery directly:
As you open the bottle valve shortly, then if you later open some gas appliance valve (f.e.
gas stove) you may hear "a hizz" and may even light it up for a second. That is also a practical
way to check for leaks in system. Now, if you have tried to start your heater in meantime and
found that gas is disappered from distribution lines, you know that your Aquaflex had succeeded
to open gas flow at least for a moment (during starting sequence). If there is still pressure
left in lines then one of the needed valves has failed to open.
