Duct Connection; Rigging Unit For Lifting; Condensate Drains - Lennox KGC092 Installation Instructions Manual

Duct Connection

All exterior ducts, joints and openings in roof or building
walls must be insulated and weather-proofed with
flashing and sealing compounds in accordance with
applicable codes. Any duct passing through an
unconditioned space must be insulated.
CAUTION
In downflow applications, do not drill or punch
holes in base of unit. Leaking in roof may occur if
unit base is punctured.

Rigging Unit For Lifting

Rig unit for lifting by attaching four cables to holes in unit
base rail. See figure 2.
1- Detach wooden base protection before rigging.
2- Connect rigging to the unit base using both holes in
each corner.
3- All panels must be in place for rigging.
4- Place field‐provided H‐style pick in place just above
top edge of unit. Frame must be of adequate
strength and length. (H-style pick prevents damage
to unit.)

Condensate Drains

Make drain connection to the 1" N.P.T. drain coupling
provided on unit.
Note - The drain pan is made with a glass reinforced
engineered plastic capable of withstanding typical joint
torque but can be damaged with excessive force. Tighten
pipe nipple hand tight and turn an additional quarter turn.
A trap must be installed between drain connection and an
open vent for proper condensate removal. See figure 3 or
4. It is sometimes acceptable to drain condensate onto
the roof or grade; however, a tee should be fitted to the
trap to direct condensate downward. The condensate line
must be vented. Check local codes concerning
condensate disposal. Refer to pages 2 and 3 for
condensate drain location.
Units are shipped with the drain coupling facing the front
of the unit. Condensate can be drained from the back or
bottom of the unit with the following modifications. The
unit can be installed in either downflow or horizontal air
discharge regardless of condensate drain location.
Rear Drain Connection
1- Remove heat access door. See figure 5.
2- Remove filter access door.
3- Remove eight screws holding condensate drain
mullion and remove mullion.
4- Lift front edge of the drain pan (to clear bottom drain
plug) and slide drain pan out of unit. See figure 6.
5- Make sure the cap over the unit bottom drain hole is
secure.
6- Rotate the drain pan until the downward slope is
toward the back of the unit. Slide the drain pan back
into the unit. Be careful not to dislodge the cap over
the bottom drain hole.
