Note: When converting to this configu- ration on an existing heater, visually inspect the heater and make certain it does not have scale buildup on the

bottom of the tank. Scale can restrict the flow of water into the tank.

CAUTION!! Scalding injury and/or water damage can occur from either the manual lifting of the lever or the normal operation of the T&P valve if it is not piped to a proper drain. If the valve fails to flow water or reseat, call a plumber.
