HEAT EXCHANGER REVERSAL PROCEDURE (POLYMER HEADER MODELS)

1.Remove right and left side access panels (Figure 1).

2.Disconnect wires at high limit, AGS (automatic gas shutoff), and pressure switch on the inlet/outlet header (Figure 2).

3.Electronic Ignition Heaters: Remove the thermo- stat temperature sensor by loosening the compres- sion fitting nut (Figure 3). Reroute the sensor to the left side of the heater.

4.Millivolt Heaters: Remove the temperature sensor bulb and retainer clip from the sensor well (Figure 4). Reroute the sensor bulb to the left side of the heater.

5.Remove (12) bolts holding the inlet/outlet and return headers to the tube sheets. Clean off tube sheet area where the gasket seats. Also clean off the header and the gasket. Apply a non-petroleum based lubri- cant to the gasket such as Aqua Lube. Reattach the headers to the opposite sides, making sure they are installed in an upright position (Figure 5). Do not over tighten. Torque should not exceed 7 ft/lbs.

6.Reconnect high limit, AGS, and pressure switch wires.

7.Electronic Ignition Heaters: Insert the temperature sensor in the compression fitting and tighten 1/2 turn past hand tight.

8.Millivolt Heaters: Insert sensor bulb and retainer clip into sensor well.

9.Allow for water flow through the heater and check for leaks.

10.Reattach access panels to the opposite sides.
