DESCRIPTION

WORKING PRINCIPLE

The HeatMaster® is a high performance hot water producer

ENGLISHFRANCAISNEDERLANDSESPAÑOLITALIANODEUTSCH

using indirect heat transfer due to it’s Tank-in-Tank technology.

At the centre of the HeatMaster® there is a stainless steel cylinder through which the flue tubes pass. It is surrounded by a mild steel shell containing the primary water (neutral fluid). The outer shell extends down to the combustion chamber and also surrounds the flue gas tubes. The heat exchange surface is therefore larger than that of traditional direct fired hot water boilers.

A circulating pump installed on the primary circuit moves the water around the tank, heating rapidly and maintaining it at a constant temperature across the primary circuit.

The burner heats the primary fluid which indirectly heats the stainless steel cylinder containing the hot water. As with all Tank-in-Tank systems, the cylinder is corrugated over its full height and suspended in the HeatMaster® by its hot and cold water connections.

The fact that the cylinder expands and contracts during use and that the cold water is not in contact with the intense heat from the burner flame means that the build-up of lime scale is prevented.

This resistance to lime scale, along with the corrosion resistance of the stainless steel, eliminates the need for sacrificial anodes.

The HeatMaster® has a major advantage over other hot water boilers: it heats hot water with a primary circuit, which allows the primary fluid to also be used for heating.

The connection of two, three, four or more HeatMaster® in a cascade meets the most demanding requirements in hot water and in heating.

Indeed, if it is used in combination with Smart, HR and Jumbo cylinders, the HeatMaster® can respond to the most demanding hot water requirements.

TEMPERATURE CONTROL

The HeatMaster® 201 are equipped with an electronic controller MCBA [MicroproCessor Burner Automate], which handles both the safety functions (ignition, flame monitoring temperature limitation, etc,…) and the temperature control of the boiler. This MCBA can also operate as a regulator governed by outdoor temperature when the outside temperature sensor is fitted. However, this regulator can also operate with a standard room thermostat (on/off). Combining this regulator with a room thermostat provides temperature control governed by outdoor weather conditions, with indoor compensation. The user may access four parameters to adjust all the necessary settings. By entering a specific maintenance code into the unit, qualified installers may access certain parameters, in order to adapt the boiler to special requirements. In principle, these are factory preset for all normal applications.

CONSTRUCTION FEATURES

Outer body

The outer body containing the primary fluid is constructed from carbon steel (STW 22).

TANK-IN-TANK accumulator/heat exchanger

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

Combustion gas circuit

The gas combustion circuit is protected by paint and includes:

• Flue tubes

The HeatMaster® include 8 tubes (HeatMaster® 71-101)

and 15 tubes (HeatMaster® 201) in steel with an internal diameter of 64 mm. Each tube is equipped with a stainless steel turbulator designed to improve thermal exchange and reduce flue gas temperature.

• Combustion chamber

The combustion chamber of the HeatMaster® models is

entirely water cooled.

Insulation

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

Casing

The boiler is covered with a steel jacket which has been de-greased and phosphated before being stove enamelled at 220 °C.

Burner

The HeatMaster® 71 - 101 - 201 models are always supplied with a low NOx air/gas pre-mix burner ACV BG 2000-M.

FROST PROTECTION

The boiler is equipped with an integrated frost protection: as soon as the boiler temperature [NTC1 probe] drops below 7°C, the central heating pump is activated. As soon as the NTC1 temperature is lower than 3°C, the burner ignites until the temperature exceeds 10°C. The pump continues to turn for approximately 10 minutes. If an outside temperature sensor is connected, the pump is activated as soon as the external temperature goes under the pre-defined threshold.

In order to enable the HeatMaster® boiler to protect the system against freezing, all the valves of the radiators and the convectors should be completely open.

PACKAGING

HeatMasters® 71 and 101 are supplied completely assembled and ready for use.

The HeatMaster® 201 is supplied in four separate packages.

664Y2500.B

• Package N° 1: Foam insulated body + hydraulic accessories + control board.

• Package N° 2: Flue reducer.

• Package N° 3: The jacket.

• Package N° 4: The burner and its cover, door insulation and sealing cord.

USER GUIDE

USE OF THE BOILER

ENGLISHFRANCAISNEDERLANDSESPAÑOLITALIANODEUTSCH

ACV recommends that the boiler is inspected and serviced, if required, at least once a year by a competent and qualified

engineer. More frequent servicing may be required depending on boiler use, if this is the case consult your installer for advice.

Starting the burner: In normal operation, the burner starts automatically as soon as the boiler drops below the temperature setpoint.

The user must not attempt to gain access to the components inside the control panel.

control panel

Heating circuit pressure

It may be necessary to add water to obtain the correct

pressure required in the heating system. This pressure is displayed on the temperature-pressure gauge on the boiler control panel.

The minimum cold fill pressure should be 1 bar. The

precise operational pressure will depend on the height of the building (See Bringing Into Service section - Filling up of

DHW and heating circuits)

.

1 2 43

If the pressure falls to below 1 bar, the boiler low water

pressure switch will stop the boiler until the pressure is re-established.

Safety valves

If water is discharged from one of the safet y valves, stop the boiler and call an engineer.

ELECTRICAL CONNECTION

Electrical supply

The boiler uses a single phase supply at 230V - 50 Hz. A double

ENGLISHFRANCAISNEDERLANDSESPAÑOLITALIANODEUTSCH

pole isolator with a 6 Amp fuse or a 6 Amp MCB must be fitted outside the boiler to allow the power to be shut off during servicing and before any repairs are carried out.

Compliance

The installation must comply with current technical standards and legislation in force.

Safety

The stainless steel cylinder must be connected separately to earth.

The power to the boiler must be isolated before any

work is carried out on it.
