What is the maximum length of a horizontal chimney connector?

Explanation:
Horizontal runs of a chimney connector are limited because a longer, flat path fights against the natural draft and is more prone to moisture, creosote buildup, and backdraft. Keeping the run short helps maintain a reliable draft and reduces the chance that combustion byproducts will spill into the living space. In typical residential solid-fuel venting, the horizontal connector should not exceed ten feet. If more length is needed, introduce a vertical rise sooner or use a listed venting system designed for longer horizontal runs, following the appliance and code specifications.
