DESCRIPTION
OPERATING PRINCIPLE
The HeatMaster is a high performance, direct fired hot water storage heater, which has indirect heat transfer due to its Tank-in-Tank construction.
At the heart of the HeatMaster is a stainless steel cylinder through which the flue tubes pass. This is surrounded by a mild steel shell containing the primary water (neutral fluid). The outer shell extends down to the combustion chamber and even around the flue tubes. The area of the heat transfer surface is therefore much greater than that of standard direct fired water heaters.
A circulating pump fitted to the primary circuit moves the water around the tank, heating it faster and maintaining an even temperature across the primary jacket.
The burner, either gas or oil, fires onto the primary water which indirectly heats the stainless steel cylinder containing the DHW.As with all Tank-in-Tanks, this is corrugated over its full height and suspended in the HeatMaster by its hot and cold water connections.
The cylinder expands and contracts during use and this, together with the fact that cold water does not come into contact with the intense heat of the burner flame, means that limescale buildup is prevented.
This scale resistant feature, along with the corrosion resistance of stainless steel, eliminates the need for sacrifical anodes.
The HeatMaster has one very major advantage over other direct fired water heaters - because it heats the DHW with a primary circuit, this primary water can be used to provide central heating as well.
By connecting two, three, four or more HeatMasters together in a module, most hot water and heating demands can be met.
Indeed, when used in conjunction with HR and Jumbo hot water storage tanks the Heatmaster can supply even the largest hot water requirement.
Standard equipment
The HeatMaster 60 N / 70 N / 100 N and 150 Jumbo has the following items as standard :
- On/off switch
- Summer/Winter switch
- Timeclock
- primary circulating shunt pump
- primary expansion vessels
- primary safety valve
- pressure and temperature gauge
- drain valve
- body completely insulated in rigid polyurethane foam
CONSTRUCTION FEATURES
Outer body
The outer body containing the primary fluid is made of thick STW 22 steel.
TANK-IN-TANK heat exchanger
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 paint-protected and comprises:
• Flue pipes
Depending on output, HeatMaster models contain several steel flue pipes with an internal diameter of 64 mm. Each pipe is fitted with a baffle of special steel designed to improve heat exchange and reduce flue gas temperature.
• Combustion chamber
The combustion chamber on HeatMaster models is entirely 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.
Casing
The boiler is covered by a steel jacket which has been scoured and phosphated before being stove enamelled at 220 °C. The jacket of the HM 150 Jumbo is delivered separately and must be assembled on site following the instructions supplied with it.
Burner
All HeatMaster models can be fitted with pressure jet gas burners or oil burners.The HeatMaster 60, 70 and 100 can also be fitted with the low-NOx pre-mix BG 2000 gas burner.

BOILER ROOM
Important
•Keep vents free at all times.
• Do not store inflammable products in the boiler room.
• Do not store corrosive products near the boiler, such as paints, solvents, chlorine, salt, soap and other cleaning products.
• If you smell gas, do not switch on the light or light a flame.Turn off the mains gas tap at the meter and inform the appropriate services immediately.
Access
The boiler room must be large enough to allow good access to the boiler.The following minimum distances are required around the boiler:
- front 500 mm
- side 100 mm
- behind 150 mm
- above 700 mm
Ventilation
The boiler room must be fitted with top and bottom vents sized according to the table below or to current regulations.
The table below gives an example conforming to the Belgian standards.
Other countries should refer to their own standards.
Base
The base on which the boiler rests must be made of non-combustible materials.
CHIMNEY CONNECTIONS
IMPORTANT Boilers must be installed by an approved heating engineer, in accordance with the prevailing local standards and regulations.
Flue size should not be less then the outlet size of the boiler.
Chimney connection type: B23
The boiler is connected to the chimney by a metal pipe rising at an angle from the boiler to the chimney.
A flue disconnection piece is required.
This must be easy to remove to give access to the flue pipes when servicing the boiler.
Note: Regulations vary from country to country therefore the table above is intended only as a guide.
Due to the high efficiency of our boilers, the flue gasses exit at low temperature. Accordingly, there is risk that the flue gasses could condense, which could damage the chimney. In order to avoid this risk, it is strongly recommended that the chimney be lined.

INSTALLATION
Example of heating + storage connection
Recommended for applications requiring a high peak flow.
Example of series connection
Preferable for high temperature applications with up to three units.
Example of parallel connection
Recommended for applications with a high continuous flow.
DANGER! As a safety measure against scalding, we strongly recommend installing a thermostatic mixing valve.
HOT WATER CONNECTIONS
Pressure reducing valve
If the mains water pressure is greater than 6 bar, a pressure reducing valve must be fitted.
Expansion relief valve
The tank expansion relief valve must be ACV approved and calibrated to a maximum of 7 bar. The valve discharge must be connected to the drain.
Hot water expansion vessel
A hot water expansion vessel must be installed.
Hot water circulation
If the tank is situated a long way from the point of use, then installing a recirculation loop can provide a faster supply of hot water to the outlets.
Temperature and pressure relief valve
If using the HeatMaster as an unvented hot water unit, in some coun­tries, a temperature and pressure relief valve must be fitted - consult your ACV stockist for assistance.

HEATING CONNECTION
The HeatMaster has two connections at the rear that can be used to connect a central heating circuit. Connecting a heating system may reduce the domestic hot water performance.
Expansion
The HM 60 is fitted with an 8 litre expansion vessel. HM 70/100 models are fitted with two 10 litre expansion vessels, and the HM 150 Jumbo is fitted with four 8 litre expansion vessels. These expansion vessels are sized f or hot water oper ation only. If a heating system is connected to the primary circuit, calculate the expansion capacity necessary for the total volume of the heating system.
(Refer
to the technical instructions from a relevant manufacturer of e xpansion vessels)

FILLING THE HO T WATER AND HEA TING CIRCUITS
IMPORTANT Hot water tank must be pressurised before the heating circuit is filled.
1. Close the primary circuit filling valves (A)
2. Open the stop valve (B) and the drawoff tap (C). When water flows out of the tap, the hot water tank is full and the drawoff tap (C) should be closed.
3. Fill the primary (heating) circuit by opening the valves (A) and pressurising to 1 bar.
4. Open the automatic air vent located on top of the boiler.
IMPORTANT - the screw cap must be left loose to allow future automatic venting to take place.
5. After venting the air from the system, bring the pressure up to the static head plus 0.5 bar: 1.5 bar = 10m and 2 bar = 15 m.
6. Check that the electrical connection and boiler room ventilation conform to the relevant standards.
7. Set the thermostat between 60 and 90 °C.
8. Switch the on/off switch to the ON position.
9. For gas burner, check the gas supply pressure on starting up.

BURNER FEATURES
ACV BG 2000-S PREMIX GAS BURNERS
Description
The burner tube is coated with metal fibre (NIT) which, in addition to its remarkable heat exchange capabilities, gives greater durability.
The main components are a venturi and one (model 60 and 70) or two (model 100) gas valves, technology specially developed by Honeywell for low No x premix air/gas b urners with automatic ignition and ionisation flame detection. The pressure at the gas valve outlet is equal to the air pressure in the neck of the venturi, less the offset.The fan sucks combustion air through the venturi, into which the gas inlet emerges. As it passes through, the air produces a pressure differential in the constriction of the venturi and sucks the gas into the venturi outlet. A perfect mix of air and gas then passes through the fan to the burner tube.
This design ensures very quiet and safe operation:
If there is an air blockage, the pressure differential in the venturi falls, the gas flow diminshes, the flame goes out and the gas valve closes:the burner is in safety shutdown mode.
If there is a b lockage in the chimne y outlet, the air flow diminishes, and the same reactions as those described above cause the burner to shut down in safety mode.
The BG 2000-S burner fitted to the HeatMaster 60, 70 and 100 is controlled by a Honeywell module which controls burner operating safety.
BG 2000-S burners are preset at the factory for natural gas.

USER GUIDE
USING THE BOILER
Your system should be serviced at least once a year by a qualified engineer. If the boiler is subject to heavy use, it may require servicing more than once a year - consult your service engineer for advice.
Starting the burner: In normal operation, the burner starts automatically whenever the boiler temperature falls below the set temperature.
Understanding the control panel
There are no user parts inside the control panel.
1. On/Off switch
This turns the HeatMaster on or off.
2. Control thermostat - 60 to 90 °C
When using the HeatMaster as a hot water generator only, the temperature can be set between 60 °C and 90 °C. If the HeatMaster is used for both hot water and central heating, the control thermostat would normally be set at 80 °C to achieve optimum operating conditions.
3. Summer/Winter switch
This turns the heating pump (if fitted) on or off.
4. Manual reset high limit thermostat
If the boiler temperature exceeds 103 °C this safety device will activate and the high temperature indicator will light up.To reset ­first allow the boiler to cool to below 60 °C, unscrew the cap and press the reset button using a pencil or similar pointed device, replace the cap. If the fault persists, turn the boiler off and call an engineer.
5.Time clock
This allows the HeatMaster to be timed on and off and operates on a 24 hour sequence. Around the outside of the clock there are a number of white tabs, these allow 15 minute switching periods. To set the time clock simply push outwards the number of tabs required for ON period.
Remember: TAB IN = HeatMaster OFF
TAB OUT = HeatMaster ON
6.Temperature and pressure gauge
This gauge indicates both the temperature of the HeatMaster and the pressure within the primary circuit. The temperature should not exceed 90 °C - if it does, switch the boiler off and check the thermostat setting. If the fault persists, call an engineer. The pressure should not fall below 1bar , if it does the please see the 'Heating System Pressure' paragraph later in this section.
7. Low primary water pressure indicator
If this indicator lights up, the primary circuit of the HeatMaster requires topping up with water. Please see the 'Heating System Pressure' paragraph later in this section.

USER GUIDE
Heating system pressure
From time to time you may need to top up the heating system pressure.This pressure is indicated by the combined temperature and pressure gauge on the boiler control panel.
The minimum pressure when the boiler is cold should be 1 bar.The precise operating pressure required depends on the height of the building, and your installer will have informed you of this value at the time of installation
(see
Commissioning Section - Filling the hot water and heating circuits)
.
If the pressure falls below 1 bar, the boiler water pressure switch will turn the boiler off until pressure is restored.
To re-pressurise, the system needs to be topped up with water.
First, switch the boiler OFF on the on/off switch and isolate the external electrical supply. Then remove the casing top front panel by pulling it forward.The filling valves “A” and “B” can now be seen. Open both valves and allow the system to fill. When the combined temperature and pressure gauge shows the required pressure, close both valves. Replace the casing top front panel. Restore the power supply and switch the boiler on.
Safety Valves
If water discharges from any of the safety valves, switch the boiler off and call a service engineer.
