When using copper or flex connector, use only
approved fittings. Always provide a union when
using black iron pipe so the gas line can be easily
disconnected for burner or fan servicing. See gas
specifications for pressure details and ratings.
NOTE: If flex connector is used, it must be kept inside
of the heater.
