Installing the New Transformer:

10.Insert the wiring connector that goes to the gas control valve/thermostat through the wire protector on the side of the transformer box (Figure 44).

11.Attach the two (2) flag terminal connectors to the transformer by aligning and pressing down (Figure 44).

12.Position the new transformer inside the transformer box where the wiring connections are nearest their exit points (Figure 44).

13.Align the holes of the transformer mounting bracket to the hole of the transformer box and attach using the 2 hex head screws (Note: take care not to pinch any wiring between the transformer and the transformer box) (see Figure 44).

14.Insert the ground wire connector through the ground screw and tighten in place with a phillips head screwdriver (Figure 44).

15.Using the screw removed in step 6, reattach the transformer box to the water heater’s side.

16.Reattach the power supply transformer connector to the bottom of the gas control valve/thermostat by aligning and pushing upward (Figure 42).

17.Plug the electric transformer in the wall outlet and turn the gas supply back on to the gas control valve/thermostat (Figure 41).

18.Turn the gas control switch to the “ON” position (Figure 41).

19.To restart the water heater, follow the directions on the “Lighting and Operating Instructions” label located on the front of the water heater near the gas control valve/thermostat.
