Just make sure you don't have a reverse rotation pump and some type of a bypass. As long as it doesn't have a cutoff switch in the line the heater can serve as the bypass
I apologize if I mislead you in my earlier post. I thought you were saying the pump in your link was the pump on the motor.
No worries Gary, I have been going all over the place and its hard to follow. That first link in post 1 was me trying to find a 2 port pump and this one here..

is the one thats one the motor now. It does say standard impeller rotation so I think its right?
