OPERATION

3 - FLUE CONNECTIONS AND ROUTING

Connection of the coaxial flue/combustion air piping system

is in the back of the unit to the separator tube assembly. The

combustion products are vented from the

heating system and

condenser through the center of the coaxial tube, while the

combustion air is supplied through the outside ring of the

coaxial tube. Since the FCX is a condensing heating system,

flue products exiting the unit are relatively low temperature,

typically from 120 - 212 ° F (49 - 100 ° C), and saturated with

humidity. Consequently, an airtight, corrosion resistant flue

system must be provided.

Various standard option flue piping components and packages

with which to create the flue system are available.
