Dunkirk Q90-75 The Quantum 90-75 Model offers a remarkable 90% AFUE efficiency rating, dramatically reducing fuel consumption and paying for itself in substantial fuel savings. The Q90-75 utilizes a cast aluminum heat exchanger, offering greater thermal conductivity which transfers heat three times faster than conventional cast iron and produces enormous gains in heat-up speed and operating efficiency. The Q90-75 features integrated boiler control with high limit for operation, safety and diagnostics. Ignition is provided by a hot surface igniter and single stage gas valve. Air flow proving switches ensure air intake and exhaust vents are clear. All components are easily accessible for ease of installation and maintenance. Unlike conventional atmospheric boilers, the Q90-75 has sealed combustion, direct-vent forced draft design to draw fresh air from outdoors for combustion, instead of from inside the home. Cooled flue gas can be safely vented through inexpensive, readily available and easy to install PVC, after 5'' of CPVC provided with the unit. The air intake also utilizes PVC pipe.
