holder. Gently pull the two white wires out of the control compartment and coil them on top of the heat exchanger.

12.A temperature control sensing bulb is located in the front of the header on the inlet side and a manual reset hi-limit sensing bulb is located on the back side of the header on the outlet side (see Figure 17). Remove these sensing bulbs from the

header. The following steps for removal apply to all sensing bulbs:

a.If there is more than one capillary tube coming out of the header, label the capillary tubes.

b.Loosen the screw on the capillary tube retaining clip, then gently pry the clip apart until it comes free from the temperature control (see Figure 18).

c.Pull the sensing bulbs out of the temperature control.

d.Gently pull the capillary tubes into the control compartment.

e.Pull the temperature sensing bulb out of the header, and temporarily route it to the front of the heater.

13.Use a pair of diagonal cutters to cut the plastic tie around the wire bundle in the control compartment.

14.On the terminal strip, disconnect the two brown wires from No. 5 and No. 6 terminals.

15.Remove the flow switch conduit retaining clip and the elbow leading into the jacket.

16.Reach inside the control compartment and release the retaining nut in the upper right corner. The nut should only be finger-tight.

17.When the conduit is pulled away from the jacket, pull the two brown wires out of the control compartment. Coil the conduit and wires on top of the heat exchanger.

18.Use a chassis punch to put two 7/8 inch (22 mm) holes in the front left side of the jacket (see Figure 19).

19.Remove the front and rear tile covers (see Figure 15).

20.Lift out the heat exchanger assembly, turn it 180 degrees, and reseat the unit in the heater with the water connections on the left side.

21.Reinstall the front and rear tile covers.

22.Push the capillary tube(s) out through the lower hole in the left side of the jacket.

23.Install the sensing bulb(s) into the appropriate temperature control (keep in mind that the positions of the inlet and outlet have been reversed. The inlet is now behind the outlet).
