Why is there no power to my Dyno-Glo Garage Heater?

[Long Con]

Hi, I have a new Dyno-Glo Garage Heater that I connected to the breaker, and it won't turn on. Multimeter reads 120V going at each node in the heater.

Breaker is a double-pole 30 Amp Stab-Lok, rated for 240V.

I'm not sure how to troubleshoot further, and I'm hoping for some direction, please.

Update: the heater works on a 30-amp double pole Siemens breaker, but not on the Stab-Lok. I could really use some advice.
