Safety comes first
If you smell gas, do not light an appliance, touch electrical switches or use a phone in the building. Call your gas supplier from a neighbor’s phone and follow the manual’s emergency instructions. Do not repair gas piping, the display, burners, vent connectors or safety devices. Refer repairs to qualified service personnel. Combustion problems, including vent blockage or inadequate gas pressure, require a qualified service technician.

The INW five-minute procedure
Only when there is no gas odor and the code-specific response does not require stopping use and arranging service, the manual’s initial procedure is to close the hot water faucet, switch the unit OFF with its power button, wait about five minutes, switch ON, then open a hot water faucet. If the code remains, close the faucet and switch OFF. Internal repairs and vent work are for qualified personnel, not further homeowner retries. If the error still displays, call support.

Unlisted codes
For a code not listed in the chart, immediately close the hot water faucet, note the code, turn OFF power to the unit and call support. Do not substitute a repeated reset routine.
