The EL195UHNE furnace can be installed in horizontal
applications with either right- or left-hand air discharge.
Refer to FIGURE 17 for clearances in horizontal applica-
tions

*Front clearance in alcove installation must be 24 in. (610 mm).
Maintain a minimum of 24 in. (610 mm) for front service access.
**An 8" service clearance must be maintained below the unit to
provide for servicing of the condensate trap.
‡For installations on a combustible floor, do not install the furnace
directly on carpeting, tile or other combustible materials other
than wood flooring.
FIGURE 17
Suspended Installation of Horizontal Unit
This furnace may be installed in either an attic or a crawl-
space. Either suspend the furnace from roof rafters or
floor joists, as shown in FIGURE 18, or install the furnace
on a platform, as shown in FIGURE 19. A horizontal sus-
pension kit (51W10) may be ordered from Lennox or use
equivalent.
NOTE - Heavy-gauge sheet metal straps may be used to
suspend the unit from roof rafters or ceiling joists. Straps
are used to suspend the unit in this way, support must be
provided for both the ends. The straps must not interfere
with the plenum or exhaust piping installation. Cooling
coils and supply and return air plenums must be sup-
ported separately.

NOTE - When the furnace is installed on a platform or with
d
the horizontal suspension kit in a crawlspace, it must be
elevated enough to avoid water damage, accommodate
drain trap and to allow the evaporator coil to drain.
Platform Installation of Horizontal Unit
1 - Select location for unit keeping in mind service and
other necessary clearances. See FIGURE 17.
2 - Construct a raised wooden frame and cover frame
with a plywood sheet. If unit is installed above
finished space, fabricate an auxiliary drain pan to be
installed under unit. Set unit in drain pan as shown
in FIGURE 19. Leave 8 inches for service clearance
below unit for condensate trap.
3 - Provide a service platform in front of unit. When
installing the unit in a crawl space, a proper support
platform may be created using cement blocks.
4 - Route auxiliary drain line so that water draining from
this outlet will be easily noticed by the homeowner.
5 - If necessary, run the condensate line into a condensate
pump to meet drain line slope requirements. The
pump must be rated for use with condensing
furnaces. Protect the condensate discharge line
from the pump to the outside to avoid freezing.
6 - Continue with exhaust, condensate and intake piping
installation according to instructions.
