3. Press the
key to clear the fault and resume operation. Be sure to observe the operation of the unit to prevent a recurrence of
the fault. NOTE: You are allow

state.
When servicing or replacing any components of this water heater be certain that:
The gas is off.
All electrical power is disconnected.
When servicing or replacing components that are in direct contact with heater water, be certain that:
There is no pressure in the heater. Pull the release on the relief valve to relieve pressure in the heater.
Heater water is not hot.
The electrical power is off.
DO NOT USE THIS APPLIANCE IF ANY PART HAS BEEN SUBMERGED IN WATER. Immediately call a qualified service technician.
The appliance MUST BE replaced if it has been submerged. Attempting to operate an appliance that has been submerged could create
numerous harmful conditions, such as a potential gas leakage causing a fire and/or explosion, or the release of mold, bacteria, or other
harmful particulates into the air. Operating a previously submerged appliance could result in property damage, severe personal injury,
or death.
NOTE: Appliance damage due to flood or submersion is considered an Act of God, and IS NOT covered under product warranty.
