1 Safety
1.1 General safety instructions
Danger
If you smell gas:
1. Do not use naked flames, do not smoke and do not operate
electrical contacts or switches (doorbell, lighting, motor, lift
etc).
2. Shut off the gas supply.
3. Open the windows.
4. Trace possible leaks and seal them off immediately.
5. If the leak is upstream of the gas meter, notify the gas compa
ny.
Danger
If you smell flue gases:
1. Switch the boiler off.
2. Open the windows.
3. Trace possible leaks and seal them off immediately.
Caution
After maintenance or repair work, check the entire heating installa
tion to ensure that there are no leaks.
1.2 Recommendations
Warning
Installation and maintenance of the boiler must be carried out by a
qualified installer in accordance with local and national regula
tions.
Warning
If the mains lead is damaged, it must be replaced by the original
manufacturer, the manufacturer's dealer or another suitably skilled
person to prevent hazardous situations from arising.
Warning
Always disconnect the mains supply and close the main gas tap
when working on the boiler.
Warning
Check the entire system for leaks after maintenance and servicing
work.
Caution
Make sure the boiler can be reached at all times.
The boiler must be installed in a frost-free area.
If the power cord is permanently connected, you must always in
stall a main bipolar switch with an opening gap of at least 3 mm
(BS EN 60335-1).
Drain the boiler and central heating system if you are not going
to use your home for a long time and there is a chance of frost.
The frost protection does not work if the boiler is out of opera
tion.
The boiler protection only protects the boiler, not the system.
Check the water pressure in the system regularly. If the water
pressure is lower than 0.8 bar, the system must be topped up
(recommended water pressure between 1.5 and 2 bar).

4 Description of the product
4.1 General description
De Quinta Ace ketel is een hoog rendement gaswandketel met de vol
gende eigenschappen:
High-efficiency heating.
Limited emissions of polluting substances.
Ideal choice for cascade configurations.
4.2 Operating principle
4.2.1 Gas/air regulation
The boiler is equipped with a casing that also serves as an air box. The
fan draws in the combustion air. The gas is injected into the venturi and
mixed with the combustion air. The fan speed is controlled on the basis of
the settings, the heat demand and the prevailing temperatures measured
by the temperature sensors. The gas/air ratio control ensures an accurate
mixture of the required amounts of gas and air. This provides optimum
combustion over the entire heat input range. The gas/air mixture goes to
the burner, where it is ignited by the ignition electrode.
Note
The combustion air supply is checked before each burner start,
and at least once every 24 hours. During continuous operation
(e.g. supplying process water), please note that the boiler control
will reset every 24 hours.
4.2.2 Combustion
The burner heats the central heating water flowing through the heat ex
changer. If the temperature of the flue gases is lower than the dew point
(approx. 55°C), the water vapour condenses in the heat exchanger. The
heat released during this condensation process (referred to as the latent
or condensation heat) is also transferred to the central heating water. The
cooled flue gases are discharged through the flue gas discharge pipe. The
condensed water is discharged through a siphon.
4.2.3 Control facility
The control system used in the boiler, the Comfort Master©, ensures a reli
able heat supply. This means that the boiler responds practically to nega
tive environmental influences (such as limited water flow and air flow prob
lems). In the event of such influences, the boiler will not go to lockout
mode, but in the first instance will modulate back. Depending on the na
ture of the circumstances, it will temporarily switch off or a control stop will
occur. The boiler continues to supply heat as long as the situation is not
dangerous.
4.2.4 Control
The heat input of the boiler can be controlled as follows:
On/off control
The heat input varies between the minimum and the maximum values
on the basis of the flow temperature set on the boiler. It is possible to
connect a 2-wire on/off thermostat or a power stealing thermostat to the
boiler.
Analogue control (0 - 10 V)
The heat input varies between the minimum and the maximum values
on the basis of the voltage present at the analogue input.
Modulating control
4 Description of the product
7625116 - v.02 - 15022016 15

The heat input varies between the minimum and the maximum values
on the basis of the flow temperature determined by the modulating con
troller. The boiler output can be modulated via OpenTherm with an ap
propriate modulating controller.
4.2.5 Regulating the water temperature
The boiler is fitted with an electronic temperature control with a flow and
return temperature sensor. The flow temperature can be adjusted between
20°C and 90°C. The boiler modulates back when the set flow temperature
is reached. The switch-off temperature is the set flow temperature + 5°C.
4.2.6 Protection against shortage of water
The boiler is fitted with low water level protection based on temperature
measurements. By modulating back when the water flow threatens to be
come insufficient, the boiler remains operational as long as possible. With
an insufficient flow ΔT ≥ 25 K or too great an increase in the heat ex
changer temperature sensor, the boiler shuts down. If there is no water in
the boiler or if the pump is not running, a lockout (fault) occurs (at ΔT≥ 30
K).
See
Manual for the control panel.
4.2.7 Water flow
The modulating control of the boiler limits the maximum difference be
tween the flow temperature and return temperature. In addition, a heat ex
changer temperature sensor is mounted to monitor the minimum water
flow. This limits the maximum increase in the heat exchanger temperature
and monitors the maximum temperature difference between the flow, re
turn and heat exchanger temperatures. As a result, the boiler is not affec
ted by low water flow.
4.2.8 Hydraulic pressure sensor
The hydraulic pressure sensor records the water pressure in the boiler.
Change the threshold value for the hydraulic pressure sensor with param
eter setting .
See
Manual for the control panel.
4.2.9 Air pressure differential switch
The air pressure differential switch is a protection against a blocked trap or
blocked air supply/flue gas outlet.
Before start-up and when the boiler is in operation, the air pressure differ
ential switch APS measures the difference in pressure between the meas
uring points on the condensate collector p+ and the air box p-. If the pres
sure difference is greater than 6 mbar, then the boiler will lock out. Once
the cause of the fault has been remedied, the boiler can be unlocked by
pressing the button for 2 seconds.
