Tyler,
Sorry for all the cold showers!  Based on what I am hearing about the AH not firing lets break this down into several steps/questions;

• With your new Beckett Controller has the fuel stropped dribbling from the nozzle?  If so that's good
  
• I know you have checked and rechecked voltages so lets just go back to "what's supposed to happen" troubleshooting.
  

Check all the wires connecting the Beckett controller and Beckett igniter coil to the AH to include the terminals on the backside of the igniter coil if those all look good.

With the burner removed from the aqua-hot chamber and hooked up electrically to the Becket's controller and igniter coil every thing should work as if it's installed into the burner chamber of the AH.  We are going to check the fuel delivery part of the AH.

• With the burner removed from the chamber and hooked up electrically and in full view disconnect the igniter +POS wire from the Beckett controller....VERY IMPORTANT to do this as you don't need an ignition source for any fuel.
  
• Start the aqua-hot - the blower should run and a fine mist of fuel should emit from the nozzle.
  
• If a fine mist of fuel emits from the nozzle that's good.
  

Now we are going to check the ignition source

• Disconnect the FUEL +POS wire from the Beckett controller VERY IMPORTANT as you don't want a fine misting of fuel with the igniter going.
  
• Reconnect the IGNITION +POS wire from the Beckett controller.
  
• Start the AH you should have the blower running and sparks at the igniter probes (HIGH VOLTAGE) if not try adjusting the probes a little closer than the tool/jig has you setting it to and try again.
  

You should see all these happening with the burner assembly exposed and connected properly to the Beckett controller. 

Hope this helps drilling down to the issue.
