8.8 DOUBLE-WALL HEAT EXCHANGER GASKET REPLACEMENT
All sizes of the Double-Wall Heat Exchanger utilize "Clip-Type" glueless gaskets. The following
paragraphs provide the instructions to replace gaskets on channel plates and on the end plate
(first plate against frame plate)
Refer to the appropriate procedures in paragraphs 8.7.1 and 8.7.2 to open the Heat Exchanger
and remove the required plates. Following gasket replacement, close the Heat Exchanger using
the procedures in paragraph 8.7.3.
8.8.1 Replacing Gaskets on Channel Plates
1. Peel old gasket off of plate making sure all parts of gasket are removed.
2. Wipe gasket groove clean making certain that no foreign material remains that would
cause gasket to seat unevenly.
3. Clip-type glueless gaskets (Figure 8-14) are attached to the plate using the prongs which
slip under the edge of the plate to hold the gasket securely in the gasket groove. The
prongs are situated at regular intervals around the perimeter of the plate.
