should be made from the wing or engine enclosure (whichever is higher from the floor) to the
bottom of the heater. Heaters must be installed at least eight feet (2.4m) above the floor in
shops, offices, and other sections of the hangar where aircraft are not stored or housed. Refer
to NFPA 409 Aircraft Hangars.
burner flames are located 18" (457mm) above the floor or protected by a partition not less
than 18" (457mm) high as specified in NFPA 88A Parking Structures.
building or room separated from repair areas as specified in NFPA 88B Repair Garages.
Units can be set on field furnished supports/cradle with access available to furnace bottom
section, or suspended by rod hangers from the sub-frame (and lifting brackets).
I I m m p p o o r r t t a a n n t t : : Any unit that has a side base rail longer than 104" (2.6m) requires additional field
furnished supports by a qualified installer. Refer to all dimensional data and
center of gravity information in this manual. If further information is required,
contact the manufacturer's technical service department.
The unit must be hung level from side to side and front to back. It is recommended to use the
(9/16" diameter) hanging holes in the skid rail, and 1/2" threaded rod or pipe, and/or whatever
other supports may be required to adequately support the unit. A field supplied cradle or
other means of support may also be required. The installer is responsible for determining
adequate and safe suspension methods.
Rig unit using either belt or cable slings. Use spreader bars to protect the top of the unit when
it is lifted. Make sure all hardware used in the lifting/mounting process is tightened and
secured.
Refer to Figures 1 and 2 following this section for Single Furnace Make-Up Air Unit rigging
requirements. Refer to Figures 3, 4 and 5 for Dual/Triple Furnace Make-Up Air Unit rigging
requirements, which ships to the site in two sections (Figure 3 is the air handler section and 4
and 5 are the furnace sections.).
On units with a total length of less than 104" (2642mm), excluding evaporative cooler, two
holes are provided in the base rail on each side of the unit. Slide pipes beneath the unit
through these holes and attach rigging to pipes for lifting the unit.
