The stated clearance to combustibles represents a surface temperature of 90ºF (32ºC) above room
temperature. Building materials with a low heat tolerance (such as plastics, vinyl siding, canvas,
tri-ply, etc.) may be subject to degradation at lower temperatures. It is the installer’s responsibility to
assure that adjacent materials are protected from degradation.
