rectifier heater question

[bnew63]

This could be one of those dumb questions.
My schematic show voltages of 0 & 5 on the PT for the GZ34 rectifier heater.
0 volts going to pin 8(heater,cathode)
5 volts going to pin 2(heater)
I've tested my PT and get +5 volts when tested both ways.
From this I'm assuming that it doesn't matter which of the 5 volt wires goes to pin
2 or 8 of the rectifier.

Thanks Brian

It's floating 5VAC.  Just hook up those typically yellow wires.

Thanks
Like I said It's a dumb question I just want to do it right the first time
