2. Condensate from fuel fired appliances
shall be drained into an existing open receptor through an air gap that is
connected to a sanitary drainage system in accordance with the rules adopted by
the Plumbers' Examining Board, established by

heat loss system design and system load calculations such that they may be
produced for inspection upon request of a Board inspector.
8.5.5.2
Replacement Systems. A
