INTRODUCTION
TOTALLY CONDENSING : The HeatMaster® TC combines the unique ACV Tank-in-Tank concept with
ENGLISHFRANCAISNEDERLANDSESPAÑOLITALIANODEUTSCH
a dual primary circuit resulting in exceptional performance from a totally condensing combination boiler.
Tank-in-Tank technology
ACV’s advanced implementation of thermal storage technology is tried and tested and is remarkably simple, efficient and reliable. At the heart of the HeatMaster® TC is a stainless steel tank through which the flue tubes pass. This is surrounded by a mild steel shell containing the primary water, which extends down to the combustion chamber and even around the flue tubes. The burner fires onto the primary water which indirectly heats the stainless steel tank containing the hot water. As with all Tank-in-Tanks, this is corrugated over its full height and is suspended in the HeatMaster® TC by its hot and cold water connections. The area of the heat transfer surface is therefore much greater than that of standard direct fired water heaters. A much larger heat transfer surface means that Tank-in-Tank units recover much faster than any other kind of hot water storage device - and keeps boiler cycling to a minimum. The high storage temperature within the inner tank also results in exceptional hot water outputs.
Dual primary circuit technology
The HeatMaster® TC primary circuit is split into two sections ­a high temperature upper circuit and a low temperature lower circuit, divided by a separation plate. The hot water storage tank is located in the upper circuit which always operates at a temperature of between 60°C and 90°C. This is ideal for hot water production as it maintains the stored water at constantly high temperatures, eliminating bacterial formation such as Legionellae, as well as resulting in high volume hot water production. The down-firing flue tubes pass through the upper circuit, through the separation plate and into the lower circuit. The primary water here operates at a temperature typically between 30°C and 60°C for heating (dependent on the heating return temperature), perfect for condensing when working in heating mode.
Operating modes
In both heating and hot water modes, the premix gas burner fully modulates the power to match the system demand.
Heating
1
The heating return enters the lower circuit of the boiler, which allows the boiler to operate in condensing mode.
The upper circuit of the
HeatMaster® TC is kept
at a consistently high temperature due to the internal shunt pump which ensures that the primary water circulates around the heat exchanger flue tubes.
Hot water
2
With the upper circuit maintained at high temperature, the
HeatMaster® TC is always
ready to supply hot water on demand. The cold water enters through the indirect water preheater at the base of the heat exchanger and is preheated before entering the hot water tank.
The low temperature of the bottom circuit results in continuous condensation of the flue gases in hot water mode.
Dual domestic hot water tank technology
During hot water mode, the bottom circuit operates at a much lower temperature, typically 5°C to 20°C depending on the cold water inlet temperature. The incoming cold water enters the lower primary circuit via an indirect water preheater.
As this preheater is wrapped around the lower flue tubes of the combustion chamber, it is able to absorb the remaining heat from the flue gases. The result is that during hot water mode the
HeatMaster® TC totally condenses whether on full or part-load.

INTRODUCTION
DESCRIPTION OF THE SPECIFICATIONS
The HeatMaster® TC is an hot water producer combined in a condensing boiler in accordance to the Belgium "HR-Top" standard. The boiler is certified compliant with "CE" standards as a connected appliance C13(x) - C33(x) - C43(x) - C53 - C83(x),
ENGLISHFRANCAISNEDERLANDSESPAÑOLITALIANODEUTSCH
but it can also be connected as an open appliance in category B23 or as an appliance of category B23P, which can operate with a positive pressure.
Lining
The boiler is protected by a steel lining that first of all undergoes a degreasing and phosphation process before being lacquered and heated at 220°C. The inside of this lining is coated with a layer of thermal and acoustic insulation, reducing losses to a minimum.
Heat exchanger
The core of the HeatMaster® TC features a new stainless steel heat exchanger. This piece of technology represents the fruit of exhaustive research and intensive laboratory testing. It reflects ACV’s eighty years of experience in using stainless steel for heating and hot water functions. The particular geometry of the exchanger pipes is calculated to obtain a very large Reynolds number throughout its cycles. The HeatMaster® TC achieves an exceptional output that remains stable throughout the boiler’s life, given that it causes no oxidation on the exchanger, which is manufactured entirely from quality steel.
Burner
ACV uses its BG 2000-M burner for the HeatMaster® TC: this is an air/gas premix burner providing safe and silent operation while limiting emissions (NOx and CO) to an incredibly low level. Although the ACV BG 2000-M boiler is very modern, it uses proven technology and is manufactured from standard spare parts that are easily available on the market.
PRODUCTION OF HOT WATER
In addition to its exceptional hot water performances, the ACV Tank-in-Tank concept provides the follwoing advantages :
- A solution for scale deposits: thanks to the specially designed
corrugations, the hot water tank expands and contracts during the heating cycle, preventing the formation of scale.
- A guarantee against the risk of Legionnellae Disease and bacteria: the hot water tank is fully immersed in the primary
circuit and the hot water is constantly kept at a temperature above 60°C.
- Exceptional resistance against corrosion and aggression: provided by the stainless steel.
FROST PROTECTION
The boiler is equipped with an integrated frost protection: as soon as the boiler temperature drops below 7°C, the system activates the central heating pump. As soon as the NTC1 flow temperature drops below 3°C, the system automatically ignites the burner until the temperature rises above 10°C. The pump continues to run for about 10 minutes.
If an outdoor temperature sensor is connected to the system, the pump is activated as soon as the outside temperature drops below the specified threshold.
To provide efficient protection for the whole system against frost, all the valves on the radiators and the convectors should be completely open.
Temperature regulation
The basic version of the HeatMaster® TC is fitted with a microprocessor controlled regulator (MCBA) which takes over both the safet y functions (ignition, monitoring the flame, limiting the temperature, etc.) and control of the boiler temperature. This MCBA also includes a weather-dependent regulator. All you need to do is connect the outdoor temperature sensor available as an option to the device. However, this regulator can also operate with a standard ON/OFF room thermostat In addition, with the combination of a weather-dependent regulator and a room thermostat, you can control the temperatures based on the weather with compensation for the indoor temperature. There are four user adjustable parameters. By entering a special maintenance code, qualified installers can access several other parameters to adapt the boiler to special requirements. In principle, these parameters are factory set for all normal applications.

Heating system
The central heating circuit must be pressurized (see in the chapter “Installation” how to define the system pressure). The pressure indicator is located on the right-hand side of the display.
If your system needs to be refilled more than twice
a year, please contact your installer.
The CH pressure must be a minimum of 1 bar and must be checked by the end user on a regular basis. If the pressure drops under 0.5 bar, the integrated water pressure switch blocks the appliance until the pressure in the system returns to a level above 0.8 bar. The connection for a fill valve is provided underneath the appliance. The installer can also fit the system with a separate valve. Make sure that the appliance is powered off when filling the system. To do this, toggle the Start/Stop switch located on the lef t of the screen to Of f. (see the Control
panel).
For more information, please ask your installer when the system is delivered.
A safety valve is provided at the underneath of 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.

- The HeatMaster which makes it largely independent of the pressure drop in the air intake and flue gas extraction system. However, the maximum pressure drop for this system may not be exceeded, or the pressure will diminish. Nevertheless, the gas/air ratio regulator continuously guarantees optimum combustion with very low emission levels.
- The horizontal flue gas pipes must always be installed with a min. slope of 5 mm per meter, upwards from the boiler side.
- There must be no obstruction or openings for any other appliances within a radius of 0.5 metres around the flue terminal of the HeatMaster
- The maximum flue resistance is 130 Pascal for the
HeatMaster® 35 TC and 150 Pascal for the HeatMaster® 85 TC. You can use the following table as the basis for calculating
this value (please also refer to the specimen calculation presented
under the table).
Sample calculation:
The diagram below consists of the following parts: pipe with monitoring section + 2 * 90° pipe bends + 2 metres of horizontal pipe + 2 * 45° pipe bends + (2 + 1 + 1) metres of vertical pipe and fall back + discharge.
Therefore, the resistance of this system is as follows:
2.5 + (2 x 6.0) + (2 x 5.0) + (2 x 4.0) + (4 x 5.0) + 20
= 72.5 Pa.

CONNECTION TO THE GAS
- The HeatMaster® TC is fitted with a Ø 3/4” male fitting connector, on which you can connect the gas tap.
- The gas connection must comply with the applicable regulations (e.g. NBN D51-003 in Belgium) in the country of installation.
- Where there is a risk of dirt stemming from the net work, place a gas filter upstream from the connection.
INSTALLATION
- Drain the gas pipe and check in minute detail that all the boiler pipes, both inside and outside, are sealed.
- Check the gas pressure in the system. Consult the technical characteristics.
- Check the gas pressure and consumption when commissioning the appliance.
ENGLISHFRANCAISNEDERLANDSESPAÑOLITALIANODEUTSCH
DOMESTIC HOT WATER CONNECTION
Before pressurising the central heating circuit
(primary) you should first pressurise the domestic hot water tank (secondary).
The HeatMaster® TC boiler can be connected directly on the domestic hot water circuit.
Flush out the system before connecting the domestic hot water par t.
The installation must be fitted with an approved safety unit with a 7-bar safet y valve, a non-return valve and a shut-off valve.
During the heating process, the domestic hot water dilates and the pressure increases. As soon as the pressure exceeds the safet y valve setting, the valve opens and discharges a small quantity of water. Using a hot water expansion vessel
(2 litres at least) will prevent this phenomenon and reduce
water hammer ef fect.
The hot water output temperature may reach temperatures in excess of 60°C, which can cause burns. We therefore recommend that that you install a thermostatic mixer immediately after installing the appliance.
If stop valves are used in the domestic hot water
system, they can cause pressure waves when closed. Use devices designed to reduce water hammer to avoid this phenomenon.

Recommendations
Before pressurising the central heating circuit
(primary) you should first pressurise the domestic hot water tank (secondary).
- The central heating system must be completely flushed out with tap water before connecting the boiler.
- The central heating safety valve is incorporated under the appliance and must be routed to the drain with an open connection (to allow inspection).
- Two primary expansion vessels of 10 litres are integrated in the HeatMaster® 85 TC (none in the HeatMaster® 35 TC).
In function of the installation, an external expansion vessel
has to be installed.
- A temperature homogeneisation pump fits the boiler. That pump runs aswell during hot water mode aswell in heating mode. The speed selection of the pump must be set to 3.
- Fill the system with fresh water. Contact your ACV representative about the use of inhibitors.
- It is possible that the pumps are locked due to the
presence of residual water from tests completed on the appliance. Therefore, we recommend that you unblock the pumps before filling the appliance.
- You will find the connection for the filling valve and/or drainage valve on the bot tom of the appliance. Fill the appliance to a minimum pressure of one bar. Drain the whole system and re-fill the appliance to a pressure of 1,5 bar.

- Fit the condens trap, fill it with tap water and connect the hose to the drain using a connection with an inspection section. Make sure you prevent the freezing of the condensates.
The condense water-trap must be connection to
the drainage system in accordance with current standards in force.
If there is a risk of low pressure in the hot water
circuit (installation of HeatMaster® on the roof of a building), it is essential to install a vacuum breaker device onto the cold water supply.

Please see in the Technical Characteristics for optimum value.
To increase the CO
2 value, turn the venturi screw counterclockwise;
turn it clockwise to reduce the value (see diagram below ref. 2).
Then put the appliance to High Power mode by simultaneously
pressing the mode and Plus keys. Wait a few minutes to stabilise.
Check the CO2 value. It should be either equal to the full power
value or a maximum of 0.5% less than this value. If you record a significant deviation,please contact the ACV maintenance department.
INSPECTION AND MAINTENANCE
ACV recommends that you have your boilers inspected
and cleaned if need be at least once a year.
Plug out the appliance before undertaking any work, even if only recording measurements and adjusting the settings.
- Check that the condenstrap is not fouled, fill it, if need be, and check that there are no leaks.
- Check that the safety valves are operating correctly.
- Drain the whole system and if necessary re-fill the appliance to pressure of 1.5 bar.
If you have to refill your circuit more than twice a year,
please contact your installer.
- Check the boiler charge in High Power mode. If there is a big difference between this value and the original setting, the deviation could mean a blockage in the air intake pipes or flue gas extraction pipes, or that the exchanger has become fouled with an accumulation of dirt.
CHECKING THE SETTING
- Check that the parameters are set in accordance with the user’s needs: see page 3, Directions for Use.
- Check the boiler settings: this task can only be carried out by an ACV-trained installer or by the ACV maintenance department.
- Set the appliance to High Power mode by simultaneously pressing the mode and Plus keys.
