Version 2025 23/03/2021 - 11:49 3.0102.2c Clearance and isolation

Maintain a minimum clearance of 3" between combustible materials or sealants and any portion of the high-temperature device (e.g. chimney, vent, flue), unless the venting material is listed and labeled for less clearance

Install a rigid, fixed dam higher than the insulation that maintains the required clearance between high-temperature devices and combustible materials

Do not allow combustible insulation between a high-temperature device and a dam unless insulation material is rated for contact with the device

Prevent fire hazards
