ports, shown in Figure 9-2. Perform the following procedures to install these devices.
Installing the Low Water Cutoff Probe and Control Module
1. Locate the two ports in the front connection pipe as indicated in Figure 9-2a, and remove
the 3/4” plugs.

appropriate pipe dope to the threads.
3. Install the LWCO sensor(s) by screwing it into the port, as shown in Figure 9-2b.
4. Retrieve the LWCO module(2), and install onto the LWCO sensor(s) by slipping the holes
over the screws on the sensor mounting flange, as shown in Figure 9-3. Tighten screws to
secure in place.
