Condensate Removal Process:
1. Condensate mixed with flue products exits
the coil and enters the cold header box.
2. Condensate and flue products are separated.
Flue products are drawn into the combustion
air blower while condensate is drained into the
header box condensate trap.
3. Flue products are expelled into the flue. As
flue products travel up and out, they cool and
more condensate is produced.
4. Condensate travels down the walls of the
flue pipe and into drain hose.
5. Water drains down through the flue drain
hose and is emptied into the header box con-
densate trap.
6. When the cold header box condensate trap is
full, water begins draining out the condensate
drain pipe.
7. An external condensate trap is not required, but
a vent is required. The vent must extend above
the height of the condenser coil (approx. 1 inch
above the top of the cold header box).
