CHAPTER 12. MAINTENANCE REASSEMBLY
12.1 REASSEMBLY OF RISERS, SUB-COOLING COIL, AND STEAM COILS
Following preparation of all Heater components as described in ROUTINE MAINTENANCE,
Chapter 6, the Heater is ready for reassembly as described in the following instructions.
12.1.1. Riser Installation
Install the Risers as follows:
Riser Installation Instructions
1) Thread the Steam Riser into the Bottom Head.
2) Tighten the Riser until the center of the Spud is visually lined up to the cast notch on the
Bottom Head.
3) Thread the Condensate Riser into the Bottom Head.
4) Tighten the Riser until the center of the Spud is visually lined up to the cast notch on the
Bottom Head.
5) If this is a B+ II Water Wizard, thread the Sub-Cooling Coil onto the Condensate Riser, hand
tight (ref. paragraph 7.2). If this is not a B+ II Wizard Bundle assembly, proceed to step 9.
6) Measure the distance between the outside diameter of the Coil to the t
protruding through the Bottom Head on both sides of the Coil (Figure 6).
7) Position the Condensate Riser to create an equal distance between both measurements
shown in Figure 6.
8) Remove the Sub-Cooling Coil.
9) Thread a Steam Coil onto the Steam Riser, hand tight.
10) Position the Steam Riser so that the Condensate Tailpiece is aligned with the Spud on the
Condensate Riser.
11) Remove the Steam Coil.
12) Insert the properly formed Coil Gaskets into each Spud. Ensure that the Coil Gasket snaps
into the Spud (Fig. 7).
13) If the Coil Gasket is loose in the Spud, remove it and reform the six tabs to create a positive
connection into the Spud.
