- Page 7 To open Model FCX to access for installation, and/ or service, follow these steps : - Remove the control panel escutcheon molding (2) by grasping it on both sides and pulling it outward towards you and up. The escutcheon will come free of the attachment clips leaving the con- trol panel exposed.
- Page 8 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.
