INTRODUCTION

GENERAL DESCRIPTION

This boiler is available in 5 models.

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

•Designed for connection to a chimney.

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

•Equipment required: a water connection kit for heating circuit supply (optional).

•The control panel contains a main switch, a control thermostat, a thermometer, a Summer/Winter switch and knockout for the built-in ACV control system (to be ordered separately).

•DELTA Performance 25, 35, 45 and 55 models - with effective outputs adjustable between 22 and 62 kW - are shipped without burners. They can be fitted with most gas or oil burners available on the market.

•DELTA Performance F25, F35 and F45 models - with effective outputs adjustable between 22 and 54 kW - are shipped with an ACV BM R oil burner.

•DELTA Performance F55 models - with effective outputs adjustable between 45 and 62 kW - are shipped with an ACV BM oil burner.

•DELTA Performance G25, G35, G45 and G55 models - with effective outputs adjustable between 22.5 and 49 kW - are shipped with a BG 2000-S gas burner.

OPERATING PRINCIPLE

The “Tank-in-Tank” concept

The DELTA Performance series differs from traditional hot water producers in that it has a ring-shaped tank immersed in the primary fluid contained in the outer body. When hot water from the central heating system or the domestic hot water system is needed, the thermostat starts up the burner. The combustion gases quickly heat up the primary fluid, thus creating a natural circulation around the tank.

Indirect hot water heating

This circulation allows easier heat exchange between the primary fluid and the domestic water, all over the tank surface. The corrugations on the inner and outer shells of the ring-shaped tank increase the area of heat exchange still further and thus speed up the process of heating the domestic water.

Easy to control and safe

With a single command, the water temperature of both the primary circuit and the domestic hot water circuit can be set by the adjustable thermostat situated underneath the tank in the primary circuit.

A cut-off thermostat, placed on the top of the boiler automatically switches off the burner when the temperature of the water in the primary circuit reaches 95°C. A manually resetable safety thermostat switches off the burner if the temperature reaches 103°C.

DESIGN CHARACTERISTICS

Lining

The boiler is protected by a steel lining that first of all undergoes a degreasing and phosphation process before being lacquered and cured at 220°C.

Heating body

The boiler heat exchanger is constructed from carbon steel STW 22 with welded joints. It is hydraulically tested under a pressure of 4.5 bar (maximum working pressure = 3 bar).

“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 surface for 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 pipes

Depending on output, the various DELTA Performance models contain either 4 or 8 steel flue pipes with an inner diameter of 64 mm. Each pipe is fitted with a special steel baffle designed to improve heat exchange and reduce the flue gas temperature.

•Combustion camber

Sealed combustion chamber. The combustion chamber is watercooled.

Insulation

The boiler body has a full sprayed-on rigid polyurethane foam insulation with a high insulation coefficient. No CFC emissions are created by the spraying process.

INSTRUCTIONS

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”.

PRESSURE IN THE HEATING SYSTEM

The Central Heating pressure must be minimum 1 bar and must be periodically checked by the end user.

Make sure that the appliance is powered off when filling the system. To do this, turn the on/off switch. For more information, please ask your installer when the system is delivered. A safety valve is provided underneath the appliance. If the system pressure exceeds 3 bars, this valve opens and drains the water from the system. In this case, please contact your installer.

INSTRUCTIONS

BURNER SHUTDOWN

If the oil burner is not working:

1.The burner indicator lamp lights.

2.Press the burner reset button on the burner. Now switch off the boiler for a few seconds at the main switch and then restart it.

If the gas burner is not working:

1.Remove the protective burner cover.

2.The reset button lamp is lit.

3.Press the reset button to start the burner. Now switch off the boiler for a few seconds at the main switch and then restart it.

If the oil or gas burner does not operate, isolate the boiler’s electrical supply at the switch on the external control box before removing the front panel of the casing, for press the manual reset high limit thermostat on the top of the boiler

Manual reset high limit thermostat

Wait until the boiler temperature drops to below 60°C, then refit the front panel of the casing.

If the problem persists, please contact your installer for advice.

Starting the burner.

In normal operation the burner starts automatically if the temperature of the boiler is below setpoint.

To ensure that your system operates correctly, please have it serviced annually by a qualified engineer; servicing should be done before the start of the heating season.
