The Tee Trap must be connected to the main condensate drain
line as conceptually shown above. Different installations may
require slightly different orientations. The following steps apply to
all installations,
1. TheTeeTrapshouldbeinstalledasclosetothesideortopof
the furnace as practical. Minimize the distance between the
inducer and the Tee Trap as much as possible.
2. An open tee is to be used at the Tee Trap discharge. The top
end of the tee should be open to the atmosphere to eliminate
potential air lock problems.
25-24-41T
3. The drain line from the Tee Trap is to be connected to the fur-
nace condensate trap drain line as shown above.
4. Condensate drain lines from a cooling coil must be con-
nected downstream of the connection point of the Tee Trap
and Furnace Condensate Trap.
Important: Prime both traps with water before operation.
Failure to prime the traps may result in discharge of flue gases
from the condensate drain line and open tee for a period of time,
and may result in temporary lockout of the furnace upon start up.
