INDEX INTRODUCTION

OVERVIEW

• Combination boiler (central heating and domestic hot water).

•TANK-IN-TANK indirect storage type domestic hot water production.

• Equipment required: a hydraulic connection kit for the heating circuit (available as an option).

• The control panel comprises an on/off switch, adjustable thermostat, thermometer, Summer/Winter selector and knockout for fitting the ACV integrated control system

(optional).

• The Delta Performance FV can be connected as a balanced flue system with a type C concentric adapter…, or with a type B23 adapter directly to the chimney.

• The Delta Performance FV 35 with a fixed output of 35 is fitted with the ACV BMV1 oil burner.

• The Delta Performance FV 50 with a fixed output of 50 is fitted with the ACV BMV2 oil burner.

DESCRIPTION OF OPERATION

The "Tank-in-Tank" concept

The Delta Performance balanced flue series differs from traditional hot water generators because of its ring-shaped tank immersed in the primary fluid contained in the outer body. When there is a demand for heat from the central heating system or the domestic hot water system, the potentiometer starts the burner. The combustion gases quickly heat up the primary fluid, creating a natural circulation around the tank.

Domestic hot water heated indirectly

This circulation facilitates heat exchange between the primary fluid and the domestic water, which takes place all over the tank surface. The corrugations on the inner and outer shells of the ring-shaped tank further boost the area of heat exchange and speed up the heating process of the domestic water.

Easy setting with safety assured

With a single command, the water temperature of both the primary circuit and the hot water circuit is set by the adjustable thermostat situated under the tank in the primary circuit. A cut-off thermostat, placed on top of the boiler, automatically cuts out the burner when the water temperature in the primary circuit reaches 95 °C. A manually reset safety thermostat shuts off the burner if the temperature reaches 103 °C.

CONSTRUCTION FEATURES

Corps externe

The outer body containing the primary fluid is made of thick STW 22 steel.

"Tank-in-Tank" type exchanger accumulator

The ring-shaped inner tank with its large heating surface for producing domestic hot water is built of Chrome/Nickel 18/10 stainless steel. It is corrugated over its full height by an exclusive production process and entirely argon arc welded by the TIG (Tungsten Inert Gas) method.

Combustion gas circuit

The combustion gas circuit is protected by a high temperature resistant paint. It is composed of:

•Flue pipes. Delta Performance balanced flue models have 8 steel flue pipes with an internal diameter of 64 mm. Each pipe is fitted with a special steel baffle designed to improve heat exchange and reduce flue gas temperature.

• Combustion chamber. The sealed combustion chamber is water cooled.

Insulation

The boiler body is fully insulated by rigid polyurethane foam with a high thermal insulation coefficient, sprayed on without the use of CFCs.

Jacket

The boiler is covered by a steel jacket which has been scoured and phosphated before being stove enamelled at 220 °C.

BOILER ROOM

Important

•Keep vents free at all times.

• Do not store inflammable products in the boiler room.

•Take care not to store corrosive products near the boiler, such as paints, solvents, chlorine, salt, soap and other cleaning products.

Access

The boiler room must be large enough to allow good access to the boiler.The following minimum distances (mm) are required around the boiler:

- front 500

- behind 150

- sides 100

- above 700

Ventilation

The boiler room must be fitted with top and bottom vents as shown in illustration "L".

The table below is an example compliant with the Belgian standard.

Note: (B) and (C) only for B23 type connections

For other countries, refer to their regulations.

Base

The base on which the boiler rests must be made of noncombustible materials.

CHIMNEY CONNECTIONS

IMPORTANT Boilers must be installed by a qualified heating engineer, in accordance with the prevailing local standards and regulations.

The chimney diameter must not be less than the diameter of the boiler connection.

Chimney connection type: B23 (See illustration L)

The boiler is connected to the chimney by a metal pipe rising at an angle from the boiler to the chimney.

A chimney connection is required

A. Top vent B. Bottom vent C. Draught regulator D. Inspection cover E. Chimney height

F. Chimney diameter

Note: Since the regulations vary from one country to another, the table above is given for information only.

Due to the high efficiency of our boilers,the flue gases are released at high temperature. Therefore there is a risk of condensation in these flue gases, which could damage some chimneys. To avoid this risk, it is strongly recommended to line the chimney. Contact your installer for more information.

Chimney connection type: C…

(see illustrations M and N)

• C 13 : concentric horizontal connection

• C 33 : concentric vertical connection

• C 43 : Concentric chimney connection

Maximum length for concentric type : 6 metres

Note: A pipe bend of 90° = an equivalent length of one metre

There should be a drain outlet close to the boiler to prevent chimney condensates entering the boiler.

To prevent condensation water running out of the terminal, all horizontal pipes should slope down to the boiler.

ACV offers an optional pre-assembled circulation kit comprising:

- a circulator.

- a 3-way manual motorisable valve.

- connecting pipes including a second optional circuit.

- two isolating valves.

- adapters for mounting safety valve with pressure gauge and filling valve to right or left of expansion tank.The expansion tank is not included.

HOT WATER CONNECTION

Pressure reducer

If the water mains pressure is greater than 6 bar, a pressure reducer calibrated to 4.5 bar must be fitted.

Safety unit

The tank safety unit must be ACV approved and calibrated to 7 bar. The valve discharge must be connected to the sewer drain.

Hot water expansion tank

Installing a hot water expansion tank avoids any risk of pressure surges due to water-hammer or pressure variations.

Hot water circulation

If the tank is situated a long way from the point of use, then installing a closed return circuit can provide a faster supply of hot water always available.

Conformity

Boiler installation must comply with the prevailing local technical standards and legislation.

Safety

The stainless steel tank must be earthed separately.

The power to the boiler must be switched off before any work is carried out.

OIL SUPPLY

System construction and installation must be in accordance with DIN 4755. Local regulations must be followed.

Oil pipes must be brought sufficiently close to the burner so that the tubes can be connected without strain. On the aspiration side of the line, fit a filter with a quick closing valve. Install a check valve on the return line.

The Burner can operate with a 1 or 2 line system. In series, the burner is designed to operate with a two-line system. The vacuum in the aspiration line should not exceed 0.4 bar.

Refer to the ACV BMV1 and BMV2 burner manual supplied with them.
