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.

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)
.

FLUE CONNECTION
- The flue connection must be carried out in compliance with the
ENGLISHFRANCAISNEDERLANDSESPAÑOLITALIANODEUTSCH
standards in force, (example: Belgium NBN B61-001), taking account of local energy supplier and fire regulations as well as regulations relating to “noise pollution”.
- The flue pipe size must not be smaller than the size of the boiler outlet connection.
Type of B23 chimney connection
The flue connection shall be achieved by means of a metal pipe rising at an angle from the boiler towards the chimney. A flue
disconnection piece is necessary.
It must be easily removable to allow access to the flue gas tubes for boiler maintenance.
The high performance of our boilers involves an exit of flue gas at a low temperature. Accordingly, there is a risk that the flue gasses may condense. In order to avoid this risk, it is strongly recommended that your chimney is insulated.

DOMESTIC HOT WATER CONNECTION
ENGLISHFRANCAISNEDERLANDSESPAÑOLITALIANODEUTSCH
The DHW tank (secondary) must filled and pressurised
before filling and pressurising the heating circuit (primary).
The HeatMaster® can be connected directly to the DHW circuit.
Flush the system before connecting the DHW circuit.
The system must be equipped with an approved safety unit including a 7 bar safety valve, a non-return valve and a stop valve.
During the heating process, the domestic water expands and the pressure increases. As soon as the pressure exceeds the safety valve set ting, the valve opens and ejects a small quantity of water. The use of a DHW expansion tank, which must be calculated according to storage volume, will avoid this and reduce water hammer.
The hot water will reach temperatures greater than 60°C, which can cause burns. Therefore, the installation of a temperature control valve on the hot flow immediately after the appliance is advised.
Example of parallel connection
Recommended for applications with high continuous flow rate.
So as to balance out the passage of water in the
th r ee b oil ers, equ ali sing val ves are c ompulso r y in this type of system.
Example of series connection
Preferable for high temperature applications with up to three units.
If stop valves are used in the inst allation, they can cause
pressure waves when they are closed.
To avoid this, use devices to reduce water hammer.

INSTALLATION
HEATING CONNECTION
The DHW tank (secondary) must filled and pressurised
before filling and pressurising the heating circuit (primary).
The HeatMaster® has two couplings at the rear which can serve as a central heating circuit connection. Coupling to a heating distribution network may reduce the hot water performance.
Expansion
The HeatMaster® 201models are equipped with 4 8L tanks. The expansion tanks are sized only for the “hot water” function. In the case of primary circuit connection, it is necessary to calculate the expansion capacity necessary for the total heating system volume (Refer to the expansion tank manufacturer’s technical
instructions for a broader explanation).
ENGLISHFRANCAISNEDERLANDSESPAÑOLITALIANODEUTSCH
ATTENTION
The primary safety valve is supplied with a plastic
discharge tube - this is a temporary fitting and should be replaced.
The safety valve must be connected to the drain by a
rigid tube, in copper for example.
If a low heating temperature is required, the use of the
kit (code: 10800099) is required.

BURNER CHARACTERISTICS
AIR/GAS PRE-MIX BURNERS ACV BG 2000-M
ENGLISHFRANCAISNEDERLANDSESPAÑOLITALIANODEUTSCH
Description
The power continually adjusts itself according to demand; this greatly improves the operating ef ficiency for heating and hot water. The burner tube is covered with a metal fibre (NIT), which, besides its remarkable heat exchange capacity, guarantees longer burner life.
The burner’s main components are:
- a variable speed fan
- an automatic ignition and flame detection system
- a gas valve and venturi tube set specially developed for low NOx pre-mix air/gas burners
Gas pressure in the gas valve outlet is kept equal to the absolute air pressure in the venturi tube inlet, corrected by the offset adjustment on the regulator. The fan pulls the combustion air through the venturi tube whose neck is connected t o the gas valve outlet. The pressure differential created at the neck of the venturi tube by the airflow rate induces gas intake proportional to its level (the larger the air flow rate, the greater the differential and there is a larger quantity of gas intake). The air/gas combination is then introduced into the burner via the fan.
HeatMaster® 71 - 101
This principle guarantees safe and quiet operation:
In the event of low air flow, the differential across the venturi tube falls, the gas flow rate diminishes, the flame extinguishes and the gas valve closes: the burner is then in safety mode.
In the event of flue blockage or restriction, the air flow rate falls, and there are then the same reactions as those described before causing burner stop in safety mode.
