FIGURE 8 175,000 & 200,000 BTUH - FASTEN SECOND TUBE TO FIRST TUBE
9.2. 175,000 & 200,000 Btuh INPUTS - FIRST TUBE JOINT CONNECTION
Models with inputs 175,000 & 200,000 Btuh have alumatherm as the first section with a welded
Flange, the second section is unpainted aluminized steel. The second tube has two slots in the
un-swaged end, and fastens to the first tube using an Accu-Seal clamp (SEE FIGURE 8).
The final position of the Accu-Seal clamp is flush to the end of the second tube with the ‘reaction block’ lo-
cated in the center of the two slots in the tube. Tighten the Accu-Seal clamp (approx. 60 ft-lb) until the clamp
fully conforms to the shape of the reaction block.
Subsequent tubes in the system are steel and joint connections are made using the tube couplers provided.
Slacken the bolts and slip the coupler over the end of the pipe to be joined, making sure the
swaged end of the tube is fully inserted into the plain end of the tube before positioning the cou-
pler. The coupler must be centred across the joint before tightening.
