CONDENSATE DRAIN INSTRUCTIONS

▲
CAUTION
!
It is recommended that an external overflow drain pan
be installed under the furnace to prevent property dam-
age or personal injury from leaking condensate.
Evaporator and furnace condensate drain piping may
be manifolded together. A primary drain vent stack
must be installed and terminated below the outlet of
the secondary heat exchanger drain connection to pre-
vent water from damaging furnace controls if the pri-
mary drain outlet plugs up. Where the furnace is in-
stalled above a finished ceiling, the primary drain vent
stack must be installed such that overflow from the
vent stack opening will flow into an auxiliary drain pan
in order to prevent water damage to the finished ceiling
below. See Figure 42.
@
If upflow furnace is installed
over a finished ceiling, overflow
from the primary drain vent
stack must flow into an auxillary
drain pan to prevent damage to
the finished ceiling below.
Primary drain vent stack
must terminate below
secondary heat exchanger
condensate drain outlet.
