Q95M-200 Modulating Condensing Boiler
Dunkirk's Q95M-200 gas-fired modulating condensing boiler was the first 95% AFUE gas boiler available and the first boiler to qualify for the U.S. Federal Government's $150 Homeowner High Efficiency Tax Credit. Ideal for high efficiency replacement jobs, new homes, radiant heating, and domestic hot water applications, Q95M cost saving features include infinitely modulating capacity from 80 to 200 MBH, outdoor temperature reset, and domestic hot water priority. Intake and flue gasses can be piped with readily available 3" PVC to 60' and the contractor has the option of left, right or rear exit for return plumbing and gas piping. Piping connections on the rear and top of the units facilitate multiple boiler installations with boilers in close quarters and the integral condensate trap requires no field assembly. The unit features a standard 115v convenience outlet as well.

Q90-100 Series Condensing Boiler
The Q90-100 offers a remarkable 90% AFUE efficiency rating, dramatically reducing fuel consumption and paying for itself in substantial fuel savings. The Q90-100 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 Q90-100 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 Q90-100 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.
