Responsive to the third snapshot being migrated, directing a request regarding the customer tenancy to the second IAM system.

Abstract: A coil of several turns in the form of a spiral is mounted in a domestic fireplace with its axis oriented horizontally and perpendicular to the front of the fireplace. The coil is supported as on legs, and serves as a grate for fuel placed within it from the front. A semicircular hood covers the upper portions of the turns of the spiral, and has a front end closure that blocks forward escape of smoke from the fireplace. Heat exchange liquid is circulated through the coil to be warmed by combustion of the fuel.
