Inlet Shut-off Valve Installation
-49-
In the following section, the instructions detail how to install the Inlet Shut-off Valve. If installed,
this device will shut off the water supply to the water heater after the Leak Sensor has sensed
and verified a water heater tank leak has occurred. The Accessory Module and Leak Sensor
must be installed for the Inlet Shut-off Valve to work with the water heater gas control.
The inlet shut-off valve can take up to 16 minutes to close, if installed, after a water heater tank
leak is sensed and verified.
Unpack the Inlet Shut-off Valve
Step 1: Remove the Inlet Shut-off Valve and its components from their packaging, as shown in Figure 70.
Prepare the Water Heater for the Installation of the Inlet Shut-off Valve
Step 2: If the water heater is already installed and the water heater is full of water, pressure must be
removed from the water heater tank, and the tank must be at least partially drained.

WARNING
If installed properly, the Inlet Shut-off Valve will prevent continuous flow when a water heater
tank leak is detected and verified. If damage will occur, a drain pan must be installed and piped
to an adequate floor drain.
