Condensing Economizers
2-4 Part No. 750-266
Figure 2.2 - Header Connections
For retrofit installations the economizer is installed in line with the existing exhaust stack or duct unless
otherwise noted. Generally a section of the exhaust stack is cut and removed to accommodate the
insertion of the economizer. The remaining portion of the exhaust stack above the cut should not
exceed a static load of 500 lbs. or exert any moments on the outlet flange, and must be adequately
supported. In some cases the economizer may be placed directly on top of the combustion source, in
effect forming the first section of the exhaust duct, with the existing exhaust stack lifted or cut to
accommodate the economizer.
For vertical flow units it is recommended that the unit be completely supported either by a floor support
structure or by threaded rods from the ceiling (design and supply of support by others). In no case
should the static load on the economizer inlet or outlet flange exceed 500 pounds. In no case should
any moment be applied to the economizer inlet or outlet. Four (4) lifting lugs are supplied on top of
the economizer for support from the ceiling and (4) support pads are supplied on the bottom of the
economizer for support from the floor.
For horizontal flow units the economizer must be set in place on a structural support (designed by
others) and/or suspended from the ceiling as permitted.
Two (2) supported I-beams or channels can be used where larger economizers are being installed. The
exchanger can then be set on the beams and slid to the lower stack and/or stack adapter for final
securing. Position four (4) tie rods (as specified and supplied by others) which can be used to suspend
units depending on upper support.
!
Warning
For all installations - no moments may be applied to the
economizer inlet or outlet flanges. Static loads over 500 pounds
are not permitted. Failure to follow these requirements may result
in equipment damage or physical injury.
