Heh I just can't find actual power consumption or explanations. 10 amps to spark gas? That's arc weld territory. A piezo should be able to ignite NG and LP, a 10 amp spark is huge.
13.75A consumption for very short durations isn't a problem. I just don't want a huge freaking electric bill for something that's supposed to burn gas. And yeah, it needs its own 15 amp circuit for it plus the fume hood, not a 20A or 30A with the dishwasher; but the dishwasher and refrigerator are, to code, allowed on the same circuit--the kitchen must have its own general circuit, but also must have a separate circuit for the stove, and both circuits must be 100% GFCI. /not an electrician
If it's just for spark, this won't eat much energy.
I'm being told to just drill into the tile floor because "put a piece of wood for the last 4 inches will make the floor weak behind the oven." Also, alternately, just to not use the anti-tip bracket because "the oven isn't going to tip over."
