B. MAIN HAB UNIT
1.
The main HAB unit has four slotted mounting holes on 15-1/2” x 34-1/2” centers.
2.
Refer to Foundation Assembly drawing for the assembly of the optional
mounting foundation.
3.
Use the provided EHAB positioning drawings to determine the approximate
position and height of the mounting foundation. The top of the foundation should
be placed 4"-6" below the height of the ties. This will allow final adjustment of
the HAB unit. NOTE: The drawing shows a standard HAB unit, but can be
used for the low profile series, also.
4.
Excavate and place the foundation in its proper location.
5.
Refer again to the drawing of the Foundation Assembly, detail A, showing the
mounting bolt arrangement. Attach four 3/4-10 x 8" hex bolts in the slotted holes
of the blower base, using a washer on each side of the blower base and a hex nut.
Draw the hex nut hand-tight and then loosen one turn.
6.
Thread a hex nut about halfway onto each bolt.
7.
Place the blower unit on the foundation using a flat washer on the top and bottom
of the foundation and another hex nut on the bottom. The slotted holes in the
foundation will allow for side-to-side adjustment, and the slotted holes in the
HAB base will allow front-to-back adjustment. However, do not tighten the
mounting nuts yet.
8.
Install the 24” flex duct onto the HAB flame duct.
9.
Now adjust the HAB unit side to side, up or down, and forward or backward to
obtain the proper alignment of the heat duct to the offset duct. It may be
necessary to adjust the position of the offset/outlet duct assembly. The
adjustments should be made so that there is no stress on any of the ductwork, also
flex duct should measure 30”. Again, leave the mounting nuts loose for now.
10.
Connect the other end of the flex duct to the HD offset duct.
11.
With all components in the proper position, the foundation nuts may
now be tightened.
12.
The fill can now be replaced around the mounting foundations.
