I have a Finest Gold. The red lockout keeps flashing suggesting an Ignition Lockout. If I turn the source (heating or water) off for a while and restart water or heating the system will work fine for a while , most times other times its a flashing lockout light. Problem is not consistent. What can be causing the problem ? sticking gas valve? Whats the remedy? Last year I had problems with switching between hot water and radiators and I believe that was a sticking diverter valve - lock light came on solid in that instance. I assume the problems are not related. Any help appreciated, thx
