I purchased a Helix radiant-heat panel and installed it today. A few hours later it was reeking - similar to a melting plastic scent - though nothing was melting. Its anchored to the top left inset of a Vision 222. Is this a "new" aroma that occurs the first time they're heated up? Regardlese, I turned it off as these fumes could be toxic?? Anyone else experience this? Panel was set at 85F.
