Lennox XP14 Elite Series Installation Instructions Manual page 4

ELEVATING THE UNIT (SMALL-BASE UNITS)
If additional elevation is necessary, raise the unit by
extending the length of the unit support feet. This may be
done by cutting four equal true-cut lengths of Schedule
(SCH) 40, 4" (101.6mm) piping to the height required as
illustrated in figure 3,
NOTE - Keep the height of extenders short enough to
ensure a sturdy installation, If it is necessary to extend
further, consider a different type of field-fabricated
framework that is sturdy enough for greater heights.
The inside diameter of the 4" (101.6mm) piping is
approximately 0,25" (6.35mm) greater than the
pre-installed feet on the unit. Devise a shim that will take up
the space and hold the extenders onto the feet during this
procedure, Small strips of 0,125" (3.175mm) thick
adhesive foam may be used, One or two small 1"
(25,4mm) square strips should be adequate to hold the
extender in place.

elevating the unit height,
If additional elevation is necessary, raise the unit by
extending the length of the unit support feet, This may be
done with 2" SCH 40 female threaded adapter. The
specified coupling will fit snuggly into the recess portion of
the feet. Use additional 2" SCH 40 male threaded adaptors
which can be threaded into the female threaded adaptors
to make additional adjustments to the level of the unit,
NOTE - Keep the height of extenders short enough to
ensure a sturdy instaflation, If it is necessary to extend
further, consider a different type of field-fabricated
framework that is sturdy enough for greater heights.
