IMPORTANT NOTES

This manual forms part of the items delivered with the appliance and 

must be given to the user to keep in a safe place!

The system must be installed, commissioned, serviced and repaired by 

an approved installer, in accordance with current standards in force.

The manufacturer declines all liability for any damage caused as a 

result of incorrect installation or in the event of the use of appliances or 

accessories that are not specified by the manufacturer.

  The manufacturer reserves the right to change the 

technical characteristics and features of its products 

without prior notice.

  The availability of certain models and their accessories 

may vary from market to market.

IF YOU SMELL GAS:

 

Gas leaks may cause an explosion that may result in 

serious injury.

 -  Do not smoke! Keep away from naked flames or equipment that 

produces sparks.

-  Do not use electrical appliances and do not operate switches

-  Close the gas supply valve.

-  Ventilate the room by opening doors and windows.

-  Make sure that there is nobody in the danger zone.

-  Notify the gas and electricity providers from outside the building.

-  Turn off the building’s electricity supply from a safe place (outside the 

building).

FROST PROTECTION

The boiler features a built-in frost protection mechanism: as soon as the 

boiler temperature [NTC1 sensor] drops below 7°C, the central heating 

pump is activated. As soon as the flow temperature falls below 3°C, the 

burner starts up until the flow temperature rises above 10°C. The pump 

continues to run for around 10 minutes.

If an outdoor temperature probe is connected, the circulator is activated 

when the outside temperature drops below the preset threshold.

In order to enable the HeatMaster® TC boiler to protect the system 

against freezing, all the valves of the radiators and the convectors 

should be completely open.

WHO SHOULD READ THESE INSTRUCTIONS

These instructions should be read by:

- the design engineer/consultant

- the user

RECOMMENDATIONS

   

•  Before installing and bringing the boiler into service, first 

carefully read this manual.

•  It is prohibited to modify the interior of the appliance in any way, 

without the manufacturer's prior written agreement.

• The boiler must be installed by a qualified engineer, in 

accordance with applicable local standards and local codes in 

force.

•  Failure to follow the instructions describing test operations 

and procedures could result in personal injury or a risk of 

environmental pollution.

•  In order to ensure the appliance operates safely and correctly, it 

is important to have it serviced by an approved contractor.

•  If there is a problem please contact your contractor for advice.

•  In spite of the strict quality standards that ACV applies to its 

appliances during production, inspection and transport, faults 

may occur. Please notify your approved contractor immediately 

of any faults.

  Remember to give the fault code displayed on the screen.

•  Defective parts can only be replaced with original factory parts. 

•  The burners are preset in the factory.

•  Specific regulation in Belgium:

  The CO

2

, gas flow, air flow and air/gas supply parameters are 

adjusted in the factory and cannot be changed in Belgium.

  

•  Before carrying out any work on the boiler, it is important to 

isolate the electrical supply to the unit.

•  The user must not attempt to gain access to the components 

inside the boiler or the control panel.

•  This appliance is not intended for use by persons with reduced 

physical, sensory or mental capacities , or lack of experience 

and knowledge (including children) , unless they have been 

supervised or instructed concerning use of the appliance by a 

person responsible for their safety.

SAFETY PRECAUTIONS

MAXIMUM OPERATING CONDITIONS
