ADVANCED BURNER TECHNOLOGY
The heart of any boiler is the burner. It’s a critical
component that’s got to be designed right. That’s
why Raypak spent over four years perfecting the
ADB burner. The result is an industrial grade, fan-
assisted burner that provides superior perfor-
mance and is practically indestructible.
Standard high efficiency boilers use burners that
are either flimsy flame retention screens that burn
out, or radial perforated burners that eventually
clog and operate at reduced efficiencies. Unlike
these burner designs, the patented advanced
design burner will not clog or burn out. In fact,
Raypak is so confident, the new burner head is
backed with a T
EN YEAR UNCONDITIONAL WARRANTY.
The ADB’s burner utilizes a solid metal bluff-body
burner head to generate a high-intensity aerody-
namically stabilized flame. The burner’s turbulent
mixing action reduces residence time and increas-
es flue gas recirculation. The result is clean, effi-
cient combustion with NOx emissions well within
the limits of the most restrictive air quality require-
ments.*
This is one tough burner and the warranty proves it.
* NOx emissions:
0-30 ppm depending on combustion air quality and
gas composition.

CENTRAL POINT WIRING AND DIAGNOSTICS
Raypak boilers have a well earned reputation for
being easy to service. The ADB is no exception. In
fact, the ADB sets a whole new standard for ser-
viceability – because it’s the first commercial boiler
to incorporate central point wiring (CPW).
Unlike older control technologies, CPW individually
monitors each and every boiler control and safety
function. Using an intuitive LED display referred to
as the Operation Status Center, CPW gives split-
second feedback on boiler firing status. Should
service be required, the ADB will even indicate
which component requires attention by illuminat-
ing the appropriate fault LED located on the ADB’s
U-2 Diagnostics Panel.
