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 ven- ted from the boiler and condenser through the cen- ter of the coaxial tube, while the combustion air is supplied through the outside ring of the coaxial tube. Since Model FCX is a condensing boiler, flue pro- ducts exiting the unit are relatively low temperature, from 140 - 185 deg. F (60 - 85 deg 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.
