GENERAL DESCRIPTION OF THE BOILER

The Remeha Quinta 45 and 65 are wall hung condensing boilers which may be also
installed free standing on a suitable frame (option). The one piece cast aluminium heat
exchanger and other major components are contained within a sealed air box. This
forms the main boiler casing with a removable front section for maintenance purposes.
All electrical and electronic controls are contained within the instrument panel mounted
behind the drop down lower front panel.
The combined flue gas outlet and combustion air inlet are mounted on the top of the
boiler with the flow, return, gas and condensate connections located at the bottom.
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 excee-
ding 3.5 bar. It must be installed on a fully pumped system and is suitable for use on
both sealed and open vented installations (minimum operating pressure of 0.3 bar).
The pre-mix, down firing gas burner (NG or LPG) with its gas/air ratio control system
ensures clean, trouble free operation with higher than average efficiencies of 110%
(NCV) in the condensing mode combined with ultra low NOx and minimum CO emissi-
ons. The standard control package allows actual and set values to be read and adjus-
ted on the built in digital display which also provides normal operating and fault code
indication.
An intelligent, advanced boiler control ('abc') continuously monitors the boiler condi-
tions, 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, air / gas supply pro-
blems) maintaining boiler output for as long as possible without resorting to a lock out
condition. At worst the boiler will reduce it's output and/or shut down (shut-off mode)
awaiting the "negative" conditions to return to normal before re-starting.
The 'abc' control cannot override the standard flame safety controls.
The boilers meet the requirements of the EC regulations and directives:
- 90/396EEC Gas appliances directive
- 92/42/EEC Efficiency directive
- 73/23/EEC Electrical low voltage directive
- 89/336/EEC E.M.C. directive
