I've said it before and I'll say it again: avoid the use of open flame with urethane belts, the fumes are not good. Instead - why not use a heat gun? Works just a well, won't fume, and you can use it in the pits. Expose just the ends of the cord from behind a shield of scrap, the ends will melt like a marshmallow when they're ready to connect.
