20 7701860 - v.05 - 22012021

QUINTA ACE RANGE
OPERATING PRINCIPLE
The products of combustion in the form of hot ue gases are forced through the heat
exchanger, transferring their heat to the system water. The ue gas temperature is reduced to
approximately 5°C above the temperature of the system return water, then discharged vertically
via the condensate collector, through the 80/125mm (Quinta Ace 30/45) or 100/150mm
(Quinta Ace 55/65/90/115, 135 and 160) combined ue/air connection to atmosphere.
Because of the low ue gas exit temperature, there will be a
vapour cloud formed at the ue gas terminal. If the controls
allow the ow and therefore return temperature to fall below dew
point (55ºC), this water vapour will begin to condense out in the
boiler, transferring its latent heat into the system water, increasing
the output of the boiler without increasing gas consumption.
Any condensate which is able to ow back into the boiler, from
ue lengths greater than one metre, must be discharged via a
condensate collector and drain system tted within one metre of
the boiler ue connection.
Combustion air is drawn into the closed air box by a variable speed
fan, through the air inlet connection from the plant room (open-
ued) or from outside via the concentric ue system (room-sealed).
On the inlet side of the fan is a specially designed Venturi which
is connected to the outlet side of the gas combi-block.
Depending on the demand (under the dictates of ow/return
sensor and other external/internal control inputs), the electronic
control unit directly monitors the volume of gas and air being
delivered to the premix burner. This mixture is initially ignited
by the combined ignition/ionisation probe which then monitors
the state of the ame. Should the ame not ignite or be unstable
within the pre-set safety time cycle, the controls will shut the
boiler down (after ve attempts) requiring manual intervention
to reset the boiler. The digital display will also indicate a
ashing fault code, conrming the reason for the failure.

CONSTRUCTION
The boiler will be a wall-hung type condensing boiler which
may also be installed free-standing on a suitable frame.
The single piece, cast aluminium heat exchanger and other
major components are contained within a sealed air box.
The boiler casing will be complete with a removable front
section for maintenance purposes. Electrical and electronic
controls will be contained within the instrument panel
mounted in the drop-down lower front panel and also the
electrical housing mounted on the inside right hand panel.
HYDRAULIC, GAS AND
FLUE CONNECTIONS
The combined ue gas outlet and combustion air inlet will be
mounted on the top of the boiler, with the ow, return, gas and
condensate connections located at the bottom. The boiler will be
suitable for room-sealed or open-ue applications. The boiler will
be designed for central heating and indirect hot water production
up to four bar. The boiler will be suitable for use on sealed
systems and open-vented installations.
OPER ATION
The boiler will be complete with a modulating control system
that limits the maximum difference in temperature between the
heating ow and return and the maximum speed at which the
ow temperature increases. The boiler will be complete with a
pre-mix burner (NG or LPG) with the gas/air ratio control system
controlled internally. An intelligent, advanced boiler control will
continuously monitor the boiler conditions, varying the heat
output to suit the system load. The control will be able to react to
external negative inuences in the rest of the system (ow rates
and air/gas supply problems), maintaining boiler output for as
long as possible without resorting to a lockout condition. Should
a negative effect happen in the system, the boiler will reduce its
output and/or shut down (shut-off mode), awaiting the negative
conditions to return to normal before re-starting. The control
cannot override the standard ame safety controls. Standard
frost protection will activate below 7°C with stage one activating
system/shunt pump. Stage two will activate below 3°C with
boiler switching on to 10°C ow.
CONTROLS
The boiler will include an “e-Smart” control platform offering
improved connectivity using the integral MK3 controller.
The controls package will allow the actual and set values to
be read and adjusted on the built-in digital display, which also
provides normal operating and fault code indication. The controls
will come as standard with the following inputs/outputs:
• 0-10V input (ow temperature or output percentage control)
•DHW temperature input
•high limit lock out
•safety/shutdown/release input (blocking)
•low water protection
•outside sensor (optional)
•external shunt pump control
•service report output
•external system pump control
•fault alarm output
•DHW 3-port valve control or pump
•OpenTherm, R-Bus & Volt Free Enable connection.
FEATURES
•Low, Class 6 NOx ≤36mg/kWh
•Fully modulating
•Quiet operation <52dB(A)
•LED illuminated interior (integral battery)
• Data le for storing fault/run info
