Rigging Unit For Lifting; Condensate Drains - Lennox LCH036 Installation Instructions Manual

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

Remove cap and make drain connection to the 1" N.P.T.
drain coupling provided on unit. A trap must be installed
between drain connection and an open vent for proper
condensate removal. See figure 3. 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 1 and 2 for condensate drain location.
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.

NOTE - Allow clearance to
open doors when installing

Connect Gas Piping (Gas Units)
Before connecting piping, check with gas company or
authorities having
requirements. When installing gas supply piping, length
of run from gas meter must be considered in determining
pipe size for 0.5" w.c. (.12kPa) maximum pressure drop.
Do not use supply pipe smaller than unit gas connection.
For natural gas units, operating pressure at the unit gas
connection must be a minimum of 4.7" w.c. (1.17kPa) and
a maximum of 10.5" (2.60kPa) w.c. For LP/propane gas
units, operating pressure at the unit gas connection must
be a minimum of 11" w.c. (2.74kPa) and a maximum of
13.5" w.c. (3.36kPa).
When making piping connections a drip leg should be
installed on vertical pipe runs to serve as a trap for
sediment or condensate. A 1/8" N.P.T. plugged tap is
located on gas valve for test gauge connection. Refer to
Heating Start-Up section for tap location. Install a ground
