1 GENERAL DESCRIPTION OF THE BOILER
The Remeha Quinta 85 is a wall hung condensing boiler 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
exceeding 4 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 0.8 bar).
The pre-mix, down firing gas burner (NG or PROPANE) with its gas/air ratio control
system ensures clean, trouble free operation with higher than average efficiencies of
109% (NCV) in the condensing mode combined with ultra low NOx 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 (
‘abc’
) 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, air / gas supply
problems) 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 boiler meets the requirements of the EC regulations at the following directives:
- 90/396EEC Gas appliances directive
- 92/42/EEC Efficiency directive
- 73/23/EEC Electrical low voltage directive
- 89/336/EEC Directive on electromagnetic compatibility E.M.C.
- 97/23/EEC Pressure equipment directive PED (art. 3, part 3)
