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.

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.

Un raccord de cheminée est nécessaire.

A. Ventilation haute
B. V entilation basse
C. Régulateur de tirage
D. Regard de visite
E. Hauteur de la cheminée tubée

F. Diamètre de la cheminée

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.

USING THE BOILER

Have your system serviced every year by a qualified
heating engineer. If the boiler is subject to heavy
usage, it may need more frequent servicing. If this is
the case, ask your installer for advice.

Starting the burner:
In normal operation, the burner starts automatically
whenever the boiler temperature falls below the set
temperature.

Before doing any work on the boiler, switch off the
power at the mains switch installed in the boiler room
by the electrician.
On the control panel, switch off the ON/OFF switch.

Getting to know the control panel (see illustration B)

The user should not access the components inside
the control panel.
