*Will have an empty slot in the manifold. These installations will require that the water/gas/condensate piping to be capped. **If the 2 unit system is in conjunction with a storage tank, a SC-401-6M is needed. However if it is just a straight tankless system then you can use a QC-2 instead of a SC-401-6M. All systems over 4 units require remote cord (RC-CORD10 or RC-CORD26). Longer Remote Cords are needed depending on which unit they install the system controller in. These lists are meant as a guide as other configurations are possible.
