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. The Q95's electrical operating costs are lower than
other high efficiency boilers because no primary/secondary dedicated piping arrangement is required. One
circulator can service the boiler and all zones. 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.


The Q90-200 offers a remarkable 90% AFUE efficiency rating, dramatically reducing fuel consumption and
paying for itself in substantial fuel savings. The Q90-200 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 units feature 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 Q90-200 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.
