s.Ensure that all burner ports are cleaned to remove any soot. See Inspection and Cleaning Procedure, page 47.

t.Carefully re-install the heat exchanger, “V” baffles, jacket panels, and wires.

u.Reassemble all gas and water piping. Test for gas leaks.

v.Cycle the appliance and check for proper operation.

Inspection of Heat Exchanger Waterways

Appliances operated in hard water areas should have periodic inspections of the tubes to be sure that no sediment or scale accumulates on the heat transfer surfaces. Inspection plugs are located at both ends of the heat exchanger. Inspection plugs should be removed and tubes inspected at the end of the first 45 days of operation and again at the end of 90 days of operation. If no scale accumulation is observed, inspections can be made at the end of each six months of operation.
