Question about Pentair Minimax NT Heater
Should the flap on the check valve outlet be open when heater is running?

What check valve?
if there is a check valve plumbed into a plumbing system, when pump comes on, then yes, check valve will automatically open!
its a one way valve! The water will flow against the flapper, pushing it open!
you have no control over that! And... Water always goes thru the heater! Whether it is firing or not / on or off, does not matter, if pump is on, water is also flowing thru heater.
