Remarkable 90% AFUE Efficiency
The UB90-200 dramatically reduces
fuel consumption and pays for itself
with substantial annual fuel
savings. Its efficiency is increased
beyond 90% when used in low
temperature systems, such as radiant
systems.
Revolutionary Cast Aluminum “Mono
Block” Heat Exchanger
This one-piece heat exchanger design
eliminates leaks that can occur due
to section interface with sectional
heat exchangers. The greater thermal
conductivity of cast aluminum
transfers heat three times faster
than conventional cast iron,
producing enormous gains in heat-up
speed and operating efficiency.
Also, the packaged boiler weighs
only 220 pounds for easier
installation.
Simplified Controls
The UB 90-200’s control design is
engineered to maximize reliability.
The UB90-200 incorporates an
integrated boiler control with high
limit and low water cut-off for
operation, safety and diagnostics.
Ignition is provided by a hot
surface igniter and a single stage
gas valve. Dual switches ensure air
intake and exhaust vents are clear.
All components are easily accessible
through the removable door.
Sealed Combustion, Direct-Vent
System
Unlike conventional atmospheric
boilers, the UB90-200 draws fresh
air from outdoors for combustion,
instead of air from inside the home.
Therefore it does not compete with
building occupants for its air
supply. With this design the
UB90-200 runs quieter and more
efficiently than a traditional
boiler.
Safe, Economical CPVC and PVC Vent
Pipe
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.
Environmentally Friendly
The UB90-200's direct-vent system,
premix gas burner and low flame
temperature reduce CO and NOx
emissions (acid rain and smog
components) by more than 30% and 50%
respectively. |
