This is a wall thimble for use with Burnham boilers in 4" stainless steel vent systems. A single wall thimble is used to ensure safe operation when venting through a combustible—and, optionally, non-combustible— wall. Burnham's stainless steel vent components are gasketed. They include pre-affixed clamp bands for quick, easy connections.
