I wondered the same thing. It is just a CG-5. No "s." Cannot convert to sealed combustion according to everyone I've talked to. Now buying a GV-5. One could try to put a heated outside air intake into the utility room with a motorized damper that opens/closes as boiler turns on/off. But that isn't exactly cheap either and would lead to massive air infiltration.
