GENERAL DESCRIPTION
• Combined boiler and water heater (heating and domestic hot water).
•Hot water generated by the TANK-IN-TANK indirect storage system.
• Equipment required: a water connection kit for the heating circuit supply (optional).
• The control panel contains a main switch, a control thermostat for the SV model or potentiometer for the MV model, a thermometer, a Summer/Winter switch and a knockout for the built-in ACV control system
(optional).
• Delta Performance models SV and MV can be connected as a balanced flue system using a type C concentric or parallel chimney adapter
xx, or connected directly to the chimney with a
type B23 chimney adapter.
• Delta Performance models SV 35 and 50 have fixed outputs of 35 and 50 kW respectively and are fitted with the ACV BG 2000-SV gas burner.
• Delta Performance models MV 35 and 50 have modulating outputs of 10 to 35 kW and 15 to 50 kW respectively, and are fitted with the ACV BG 2000-MV gas burner.
OPERATING PRINCIPLE
The “Tank-in-Tank” concept
The Delta Performance ventouse range of boilers differs from conventional hot water heaters in that it features a ring-shaped tank which is immersed in the primary water, and which is itself contained in the outer body. The thermostat/potentiometer activates the burner when the heating system or the hot water circuit calls for heat.The combustion gases quickly heat up the primary water and set up a natural circulation around the tank.
Indirect hot water heating
This circulation causes heat to be exchanged between the primary water and the domestic water; heat is exchanged across the entire surface of the tank.Corrugations on the inner and outer shells of the ring-shaped tank further increase the heat exchanger surface, thereby accelerating the water heating process.
Simple to control, safety assured
The temperature of the water in both the heating circuit and the hot water circuit is regulated by a single control. This is achieved by means of the control thermostat or the potentiometer whose bulb is located under the tank in the heating circuit. A thermal reset high limit thermostat positioned at the top of the boiler automatically cuts out the burner when the temperature of the water in the heating circuit reaches 95°C. A manual reset high limit thermostat locks the burner out if the temperature of the primary water reaches 103°C.
DESIGN CHARACTERISTICS
Outer body
The outer body which holds the primary water is made from STW 22 heavy gauge steel.
“Tank-in-Tank” type storage exchanger
The ring-shaped inner tank is made from 18/10 austenitic stainless steel and features a large heat exchanger surf ace f or rapid hot water heating. It is corrugated over its full height by means of an exclusive production process, and is fully argon welded using the TIG (Tungsten Inert Gas) method.
Combustion gas circuit
The combustion gas circuit is protected by high temperature paint. The circuit comprises:
•Flue ways. The Delta Perfor mance ventouse range has 8 steel flue ways with an inside diameter of 64 mm. Each flue way has baffles made of special steel designed to improve the heat exchange and reduce the flue gas outlet temperature.
• Sealed combustion chamber. The combustion chamber is water-cooled.
Insulation
The boiler body has full sprayed-on rigid polyurethane foam insulation with a high insulation coefficient. No CFC emissions are created by the spraying process.
Casing
The boiler is covered with a steel casing that has been stove enamelled at 220°C after scouring and phosphating.

This table is based on the equipment offered by ACV and connot be applied generally.
Sample calculation
The diagram below consists of the following parts (Ø 80 mm) :
•1 x Pipe bend 90°
•2 x Straight pipe L 2000 mm
•2 x Pipe bend 45°
•2 x Straight pipe L 1000 mm
•1 x Vertical terminal
•1 x Condensation drain vertical
Calculation:
•1 x 4,32 = 4,32
•2 x 5,1 = 10,2
•2 x 2,75 = 5,50
•2 x 2,55 = 5,10
•1 x 5,4 = 5,4
•1 x 2,06 = 2,06
Total: 32,58 x 2 = 65,16 Pa
This value is less than the maximum authorised resistance, therefore the installation is compliant.
A condensation drain outlet must be fitted close to the boiler to prevent condensation products from the chimney running into the boiler.

BURNER CHARACTERISTICS
DESCRIPTION OF THE BURNER
Gas burner ACV BG 2000-SV
ACV BG 2000 air/gas premix burners are equipped with a gas valve , a venturi and a Honeywell electrical control relay.These items have been specially developed for low NOx air/gas premix burners with automatic ignition and flame detection.
Gas burner ACV BG 2000-MV
The ACV BG 2000-MV burner is based on the technology of the ACV BG 2000-SV burner but offers the benefits of a modulating burner. The burner's output is constantly adjusted to suit the fluctuating demand for heat, thus optimising operating efficiency.
BG 2000-SV and MV burners are preset in our factory for use with natural gas
(equivalent to G20).
CONVERSION TO PROPANE: (refer to the conversion instructions)
Prohibited in Belgium.
Conversion kit supplied with the boiler comprises:
- Orifice(s).
- Propane rating plate(s).
- Self-adhesive settings label.

BURNER CHARACTERISTICS
OPERATING PRINCIPLE OF THE BURNER
AIR/GAS mixture control (Fig. 12)
The fan draws air in across the v enturi.This creates a vacuum P1 at the venturi neck. The gas valve regulator now reacts to maintain a difference equal to the amount of the offset between the pressure at the gas valve outlet P2 and atmospheric pressure P3:P2 – P3 = off-
set. If the air flow decreases, P1 rises; the same applies to P2;now
P2>P3;the regulator R moves upwards and restores the equilibrium P2 – offset = P3;pressure P4 falls and valve C moves down: the
gas flow decreases. Whatever the speed of the fan therefore, the Air/Gas ratio is m ain-
tained equal to 1 to within the amount of the offset. The difference in pressure between the neck of the venturi and the
outlet from the gas valve now draws gas through the venturi. The gas flow adjuster screw is used to adjust the amount of gas that
is to be injected for a given air flow, and this will determine the %CO
2
in the flue gas. It is now a ver y simple matter to control the burner's power by adjusting the fan speed and the %CO
2 to predefined
settings.
Ignition and flame monitoring
The control and monitoring relay has a dual function: it ignites the burner by producing sparks at the ignition electrode, and it monitors the actual presence of a flame when the gas valve is open (it measures the ionisation current).
Starting sequence: (Fig. 13) The fan starts up when the boiler thermostat/potentiometer detects
a demand for heat.After a 15 second pre-purge the gas valve opens simultaneously with the ignition. Provided an ionisation current is detected inside the first 5 seconds, combustion continues normally until heat is no longer called for.Otherwise, the gas valve closes and the fan stops; the burner is now shut down.
If the burner shuts down:
1. The burner indicator lamp lights up on the control panel and on the burner.
2. Press the burner reset button on the control panel. Turn the boiler off for sev eral seconds at the main switch, then restart the the boiler.
Gas tube (Fig. 14)
The air/gas mixture leaving the gas valve/venturi assembly is propelled into the burner tube. This tube is covered with metal fibres (NIT). This enhances the distribution of the flame, increasing its life and significantly reducing pollutant emissions. Combustion of the air/gas mixture is also spread uniformly around the circumference of the tube. The tube is also designed to withstand propane combustion.

PROCEDURE FOR SETTING THE % OF CO2
•Measure the burner combustion with an electronic flue gas analyser.
• Adjust the % of CO
2 to the figure shown in the table of setting
parameters on Page 15 by turning the gas flow adjuster screw on the gas valve.(Fig. 16)
Turn counter-clockwise (more gas) increases the % of CO
2.
Turn clockwise (less gas) reduces the % of CO2.
The offset (4) is set at the factory and requires no adjustment.Nevertheless ACV recommends that you check this setting. (Refer to the table of setting parameters). You should contact your installer should you find any significant deviation.
•Measure the speed of the impeller that is mounted on the motor shaft. Adjust the speed of the fan according to the parameters (Start, Min., Max.) listed in the table of setting parameters on Page 15 by turning the potentiometer screw (counter-clockwise to reduce the fan speed and clockwise to increase it).
Fan speed for burner BG 2000-MV:
If the fan of a BG 2000-MV burner is replaced, the fan's speed is controlled directly by the PWM connector which connects the fan to the p.c.b.
The potentiometers on the p.c.b. (Start, Min. and Max.) must be adjusted by an engineer approved by ACV.

USE OF THE BOILER
We recommend that you have your system serviced each year by a qualified engineer.
Starting the burner: In normal operation the burner starts automatically if the temperature of the boiler is below setpoint.
Before carrying out any work on the boiler, isolate it from the electrical supply at the switch on the external control box. Also move the main switch on the control panel to “OFF”.
You should familiarise yourself with the control panel
(Fig. 25)
The user must not attempt to gain access to the components inside the control panel.
1. Control thermostat (SV) or potentiometer (MV)
If the boiler is being used to generate hot water only, the boiler temperature can be set to between 60 and 90°C. If the boiler is being used for hot water and heating, then the boiler's control thermostat or its potentiometer should normally be set to 80°C to guarantee optimum operating conditions.
2. Main switch
This switch is used to start and stop the boiler
3. Summer/Winter switch
This switch is used to start and stop the heating pump (if a pump is fitted).
4. Thermometer
The thermometer shows the boiler temperature in the heating circuit.This temperature should not exceed 90°C.If it does, stop the boiler and check the settings on the thermostat (SV) or potentiometer (MV). If the problem persists, contact your installer for advice.
5. Resetting the burner
This switch can be used to restart the burner if it has shut down.
6. Burner indicator lamp
This lamp tells the user whether the burner has shut down (lamp on) or not (lamp off).
7. Controller
(optional)
Refer to the instructions supplied with the controller if you have this option.
Gauge pressure in the heating system
Your system must be equipped with a heating safety valve calibrated to 3 bar and fitted with a pressure gauge.
Ensure that the system is always under water pressure.When the system is cold and the air inside it has been vented, the gauge must indicate a pressure between 0.5 and 1.5 bar depending on the height of the building.
To add water:
(refer to Fig. 8 on Page 8)
•Open the filling valve (5).
Close the valve properly after filling.
•Vent the system in order to obtain
an accurate reading of the
pressure inside the heating circuit.
Safety valves (heating circuit)
If water is found to be escaping from one of the safety valves, stop the boiler and contact your installer for advice.
A monthly test is recommended: Lift the lever on the drain cock for a few seconds to ensure that the safety valve is working correctly.
If there is a problem after this short test, please contact your installer for advice.
