The secret to the stunning performance of the VF Series is its flexibility. The VF is capable of firing from 100% to 25% or a 4:1 turndown ratio. The boiler’s output is based strictly on the current system demand and required BTUs needed to maintain the desired system set point temperature. The VF’s modulating capability is virtually limitless. The VF Boiler sets a high efficiency standard by combining thermal efficiencies up to 88% with a smoother, more energy-efficient overall system operation. Combustion air intake – self adjusting-no air shutter required EMC-5000 Modulating Control Advanced pre-mix burner design precisely mixes air and gas prior to ignition for optimum performance, with low-NOx emissions (meets SCAQMD Rule 1146.2) All non-heating surface heat exchanger compo- nents are outside and away from the combustion and flue collection areas; only the copper fin tubes are exposed to the products of combustion Venturi-mixing gas/air ratio system works with variable speed blower to precisely mix gas and air throughout firing range, provides good operation with supply gas pressures down to 4.
