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

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.
