NOTE - Do not discharge exhaust gases directly into any chimney or vent stack. If ver-
tical discharge through an existing unused chimney or stack is required, insert piping
inside chimney until the pipe open end is above top of chimney and terminate as illus-
trated. In any exterior portion of chimney, the exhaust vent must be insulated.
FIGURE 46
Condensate Piping
This unit is designed for either right- or left-side exit of con-
densate piping in either upflow or downflow applications;
however, it must be installed on the same side of the unit as
the exhaust piping. In horizontal applications, the conden-
sate trap should extend below the unit, A 5-1/2" service
clearance is required for the condensate trap, Refer to fig-
ure 47 for condensate trap locations,

NOTE - In upflow applications where side return
air filter is installed on same side as the conden-
sate trap, filter rack must be installed beyond
condensate trap to avoid interference.
FIGURE 47
1 - Determine which side condensate piping will exit the
unit, Remove plugs from the condensate collar at the
appropriate location on the side of the unit.
NOTE - The condensate trap is factory-shipped with
two rubber Q-rings and two rubber clean-out caps
installed. Check to make sure that these items are in
place before installing the trap assembly.
2- Install condensate trap onto the condensate collar.
Use provided HI/LO screws to secure two upper
flanges of the trap to the collar, Use provided sheet
metal screw to secure bottom trap flange to side of
unit, See figure 48,
NOTE - In upflow and downflow applications, con-
densate trap must be installed on the same side as
exhaust piping.
