If vent pipe or combustion air pipe must be reassembled
When vent pipe or combustion air pipe is disconnected for any reason, it must be reassembled and resealed
according to this Venting Supplement, the direct vent termination kit instructions and the vent pipe manufacturer's

Vent and combustion air connector piping must be sealed gas-tight to prevent possibility of
flue gas spillage and carbon monoxide emissions, resulting in severe personal injury or death.
