Mount a Listed 2 x 4 inch, "HandiBox" type junction box over the oval hole in such manner that part of the hole is left open. When installing the junc- tion box, center the box vertically over the oval hole by using the center knockout in the box. Install a ½ inch trade size cable connector or insulating bushing in the knockout. Secure the box with screws as required.

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
