New to this great site full of info.
Question. I'm trying to "remotely" wire my old Hayward HM250 Pool Heater into my Pro Logic panel.

I've found plenty of manuals but nothing specific on where the terminal block is located inside the heater or a pic on what terminal posts to use on the terminal block. Further, the Hayward manual http://www.hayward-pool.com/pdf/manuals/H-series-Hxxx.pdf on page 19 and 20 make a vague reference to the "millivolt" heater but provide no depth of instruction/direction.
Inside shot of panel - notice no terminal block.

The only thing I can potentially guess is the terminal block is behind and inside the heater somewhere. Next, once, and if there is indeed a terminal block, what terminals do I hook the wires to? If there is no terminal block inside this heater I guess I'm just SOL.
Any experts out there that know the guts to these old heaters care to comment? Thanks
