SECTION S: CONNECTING CONDENSING HEAT EXCHANGER (CHX)

Refer to Figure S-1 for the following steps:

1.Remove the shroud

2.Remove the top cover.

3.Secure the 15° elbows (supplied) as shown one on each side of the CHX, using the stainless steel screws (sup plied).

4.Seal the connection with high temperature RTV (supplied).

5.Replace the top cover.

6.Level the CHX with the ADB by adjusting the leveling screws at the base.

7.Place a line of RTV on the crimped end of the flue outlet from the ADB and slide the CHX to join the ADB flue outlet to the CHX flue inlet.

8.Connect the CHX water as specified in the piping diagram. Check for water leak.

9.Secure the flue connection from step 7 above with the stainless steel screws (supplied).

10.Connect the flue vent (Category IV venting, UL 17-38 Certified Venting Material) to the 15° elbow of the CHX flue outlet.

11.Connect the PVC pipe (not supplied) for condensate water disposal (check with local authority regarding conden sate disposal).

12.Replace the shroud.

VENT SWITCH ADJUSTMENT:

In order to insure proper operation of the ADB boiler with a CHX attached to it, the vent switch must be adjusted to proper setting. The vent switch is located on the J-box, just outside the ignition module. Use the following steps:

•Turn power off; disconnect the electrical wiring and the rubber hose.

•Remove the switch (it has a black plastic orifice at the hose connection).

•On the backside, remove the (purple) seal from atop the adjusting screw.

•Turn the plastic hex screw 1 1/2 turn clockwise.

•Seal with silicone.

•Reinstall in reverse order.
