INDOOR CLEARANCES TO COMBUSTIBLES
4.1)
The stated clearance to combustibles represents a surface temperature of 90º F (50º C) 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.
See below the possible surface temperature at the clearance to combustible distance for different ambient
temperatures within the heated space.
