10.0)

U-TUBE HEATER ASSEMBLY

See heater dimensions and assembly overview (Sections 7.0 and 7.1) for each U-model configuration. It is
recommended to read the all the instructions carefully before proceeding with the installation.
During field assembly of the heater body sections, the recommended procedure is as follows:
1. Determine the actual layout of the system first before hanging heater sections. Consideration must also be
taken for flue pipe, fresh air ducting, gas piping, clearances to combustibles, etc. before hanging heater.
2. Install the heater suspension chains (or alternate methods) outlined in Section 9 "Typical Suspension
Methods". Space the suspension points according to the hanger bracket spacing dimensions (see section
7.0) for each heater. Use spanning steel work if necessary to position suspension points. Note: Suspension
points are fixed along the length of heater to accommodate the side panels.
3. Space the hanger brackets according to the dimensions shown in the figures below for the first tube section.
Note: The distances are measured from center of the holes of each support/hanger bracket. See figure 21
below for ADU25 and Figure 21a for ADU30/35/40/45. (Note for ADU25 install all three hanger brackets).
