Painting gas stove top

Get the 220v outlet while you can. With that wiring, you can run two 110v circuits in the future or install an electric oven if you change your mind. Running another line in the future would be much more difficult, so now is the time to have it installed. The only change you'll likely have to make is replacing the double breaker with two single breakers if you want 110v, which any electrician should be able to do with minimal effort.

It is possible that a few of the gas nozzles closest to the ignitor are clogged or blocked, and so the burner will not light until there is so much gas pumped out that it eventually makes it to the igniter, and hence the explosion. You should clean it out, and if that doesn't work, replace the ignitor.
