HI,
On reading the instructions of how to attach the thermo boards to a concrete floor, it states to use a flexible tile adhesive. But, does I user floor leveler first then the thermo boards? Are there any set rules for the layers required, i.e. PVA sealer first -> flexible tile adhesive -> themoboards -> heating mat – > floor leveler

The thermal boards require a stable and level sub floor to be installed onto , if its going onto a concrete base then tile adhesive would be required to be used , IF its going onto a plywood type of subfloor then you can use the screws and washers provided with the thermal boards to secure it down.
