Creighton,
Every cooktop I've seen with igniters is cord & plug connected... the igniters draw very little energy, as the 25W light in the over also... I typically place the outlet +18"AFF behind the unit...

PS... I've come across a couple gas ranges with "browning elements" in them, which are electric. The ones I saw required a dedicated circuit per mfr instructions (1750W 120V).
Just something to keep an eye open for
