Remove the left and right jacket side panels from Box
55175, Jacket Side Panels. Remove the knockouts
necessary to attach the water or steam piping and
controls.
NOTE: All jacket panel joints must be made so the
panels are metal to metal. The insulation on the edges
of the front, top and rear panels must be pushed
behind the side panel flanges before fastening the
panel together, Figure 74.
Figure 74 Jacket Insulation Detail
Slip the rear flange of one of the side panels between
the rear panel and the jacket-mounting bracket, Figure
75.
Figure 75 Jacket Side Panel Installation
Fasten the side and rear panels together using the bottom
three holes, Figure 76. Align the bottom screw hole with
the hole in the jacket bracket and fasten them to the
bracket. Attach the opposite side panel the same way.
Figure 76 Jacket Side Panel Installation
Locate the top jacket panel(s), Figure 77.
Figure 77 Top Jacket Panels
If the removal of knockouts is required to accommodate
any piping they should be removed at this time. Place
the rear top jacket panel on top of the boiler, Figure 78.
On 13 through 21 section boilers two top jacket panels
are required. These panels should be screwed to the
top splice panel before being placed on the boiler,
Figure 79. Make sure that the splice panel flanges are
between the edge of the top panel(s) and the insulation,
Figure 80. Attach the edges of the top jacket panel(s)
so they are metal to metal with the top flanges on both
side panels.
