Burnham FM01FD00B manual Hand Form Support Channel Bracket

Repeat this process for each joint, securing the previous assembly to the tube shown in next column to the right in Table VII, also refer to Figure 13

for details. If space behind the boiler is limited, on RWMT’s having two or more tubes, it may be necessary to assemble the end cap to the adjoining tube and then insert the assembly, capped end first, into the 4” NPT tapping on the back of the rear section before joining the remaining tube(s). Allow approximately 1½” of the tube to protrude from the tapping, so that the next tube can be secured to the assembly. Once the next tube is secured, insert the assembly further into the tapping. Repeat this procedure as necessary for up to seven (7) tube RWMT assemblies.

4.Insert the completed RWMT assembly into the 4” NPT tapping until the end cap reaches the front of the boiler. The front support clip on the end cap must rest on the internal shelf inside of the upper 3” NPT boss on the front section. If necessary, insert

along screw driver, wooden dowel or a short length of 1/2 pipe through the 3” NPT tapping and into the support collar on the end cap to lift and maneuver the tube into position.

5.Install CI Return Manifold and 4” NPT Nipple - See Figure 9.

a.Apply thread-sealing compound to both ends of 4” NPT nipple and hand tighten nipple into one end of the CI Return Manifold (return manifold casting is symmetrical about the ends).

b.Slide the CI Return Manifold Assembly over RWMT, and install the threaded end of the 4” NPT nipple into 4” NPT tapping in rear section.

c.Wrench CI Return Manifold Assembly until watertight and ½” NPT tappings (positioning plugs) are aligned with vertical axis of rear section as shown in Figure 14.

6.Thread upper and lower positioning plugs into 1/2” NPT tappings. If necessary, push forward or pull back on RWMT assembly and/or rotate until pins on positioning plugs engage alignment holes in tube, see Figure 13. Wrench both plugs until water tight.

7.Install RWMT front support plug into 3” NPT tapping on upper front section boss.

a.Looking through 3” tapped hole, check position of support collar on RWMT end cap. Collar should be located approximately in the center of the tapped hole both vertically and horizontally.

b.If necessary, adjust support collar position before installing front support plug. For horizontal adjustment, bend support clip up or down per the amount of visual mis-alignment.

c.Thread front support plug into 3” NPT upper front section boss, wrench plug water tight.

C.Install Jacket Support Frame to Block Assembly.

1.Locate Jacket Frame Carton(s), marked ‘JF’ and remove contents, see equipment list on Page 3 for quantity required.

2.Open “JF-P” Jacket Frame Parts Carton(s), packed inside Jacket Frame Carton(s), and remove contents.

3.Locate support channel brackets which are shipped flat and need to be hand formed by bending both legs down 90°, see Figure 15.

NOTICE

Orientation of return manifold is critical for proper alignment of return water mixing tube.

4.Locate horizontal support channels and FH-1 Hardware Bag(s). Position two (2) support channel brackets on floor and place horizontal support channel over brackets. All three (3) holes in both parts must be in alignment, if they are not, rotate bracket. Secure brackets to channel using four (4) #8 x 1/2 hex head sheet metal screws, see Figure 16. Repeat until all horizontal channels and brackets are assembled.
