Questions about this item

How is the SP20170A retrofit kit installed, and which step involving the gas supply is often missed?

Turn off the gas, remove the old thermostat and burner assembly, fit the new kit to the 6FGV3 unit, then restore gas and check for leaks; the step people skip is pressure-testing the connections before relighting the pilot.

What maintenance or replacement will the SP20170A kit need later?

Inspect the burner ports and thermostat sensor annually for soot or corrosion; replace the entire assembly if the pilot fails to stay lit or the thermostat no longer reaches the set temperature.

What limit appears first on the SP20170A kit under sustained natural-gas operation?

The thermostat’s high-limit safety will trip first if the water temperature exceeds the factory-set cut-off, shutting off the burner until the unit cools and the reset is pressed.
