The De Dietrich C230 ECO-A is a pre-assembled, free standing, gas
fired, high efficiency condensing boiler. The sectional cast aluminium
heat exchanger and other major components are contained within a
sealed air box. This forms the main boiler casing with a removable
inspection hatch for maintenance purposes. All electrical and
electronic controls are contained within the instrument panel mounted
on top of the boiler.
The flue gas outlet, combustion air inlet, flow, return and gas
connections are located on top of the boiler with a condensate
connection at low level on the right hand side.
The boiler is suitable for room sealed or open flue applications and
has been designed for central heating and indirect hot water
production at working pressures not exceeding 100 psi (7 bar). It must
be installed on a fully pumped system and is suitable for use on
sealed installations.
The premix gas burner with its gas/air ration control system ensures
clean, trouble free operation with higher than average efficiencies
109% (NCV) in the condensing mode combined with ultra low NO
and minimum CO emissions. The standard control package allows
actual and set values to be read and adjusted on the built-in digital
display which also provides normal operating and fault code
indication.
An intelligent, advanced boiler control (Comfort Master) continuously
monitors the boiler conditions, varying the heat output to suit the
system load. The control is able to react to external "negative"
influences in the rest of the system (flow rates, gas/air supply
problems) maintaining boiler output for as long as possible without
resorting to a lockout condition. At worst the boiler will reduce its
output and/or shutdown (shut off mode) awaiting the "negative"
conditions to return to normal before restarting.
The Comfort Master control cannot override the standard flame safety
controls.
