COMMISSIONING THE SYSTEM

   The DHW tank (secondary) must be filled and pressurised 

before filling and pressurising the heating circuit 

(primary).

The two circuits, DHW and heating, must be filled prior to 

using the appliance.

 

-  Fill the tank slowly and bleed it by opening the hot water outlet. Bleed 

all the outlets and make sure there are no leaks in the domestic hot 

water system.

-  Fill the whole system up to a minimum of 1.5 bar using the boiler fill 

valve.

  Fill the system slowly. Also check that the automatic bleed valve is 

working. Make sure there are no leaks in the central heating system.

-  Purge the charging pump and check that it rotates.

-  Open the gas valve, bleed the pipe and check for leaks in the system.

-  Ensure the condensate trap is correctly fitted underneath the boiler.

-  Connect the power cable to the boiler via the terminal provided and 

switch on the appliance. Where appropriate, put the room thermostat 

at its highest setting so the boiler starts up.

-  Check the gas pressure and leave the boiler to heat for a few minutes.

  Switch the boiler to maximum power mode and check the CO

2

(See 

technical data table)

.

  Then switch the boiler to minimum power mode and check the CO

2

(See technical data table)

.

-  Set the central heating and hot water temperatures according to the 

values indicated in the instructions for use.

-  Bleed the central heating system again and if necessary fill to reach 

the desired pressure.

-  Make sure that the central heating system is properly balanced and, if 

needed, adjust the valves to prevent certain circuits or radiators from 

getting a flow rate that is far above or below the set rate.

  The diameter of the condensate discharge pipe cannot be 

reduced. The pipe must never be obstructed.

CHECKING THE SETTINGS

   Specific regulation in Belgium for the HeatMaster® 

25 / 35 TC : the CO

2

, gas flow, air flow and air/gas supply 

parameters are factory preset and cannot be changed.

-  Check if the parameters are set to meet the user’s requirements.

-  The boiler’s settings can only be checked by a trained ACV 

installer or the ACV maintenance department.

- Switch the appliance to maximum power mode by pressing 

simultaneously on the Mode and Plus (+) keys.

-  Check the dynamic gas pressure at the gas valve 

(See diagram below, 

ref. 1)

. This must be at least 18 mbar.

  Let the appliance heat for a few minutes until it reaches at least 60°C. 

Check the CO

2

 setting of the appliance using a measuring instrument. 

The optimum value is indicated in the technical data table. To 

increase the CO

2

 value, turn the venturi screw anticlockwise, and turn 

it clockwise to decrease this value (see diagram below, ref. 2).

  Then switch the appliance to minimum power mode by pressing 

simultaneously on the Mode and Minus (-) keys. Let the appliance 

stabilise for a few minutes.

  Check the CO

2

 value. It should be either equal to the value at full 

power or a maximum of 0.5% less than it. If you observe a significant 

deviation, please contact ACV’s maintenance department.

BOILER MAINTENANCE

  ACV recommends that you have your boiler inspected, 

and cleaned, if necessary, at least once a year.

Disconnect the electrical power supply before undertaking any work 

on it.

-  Check that the condensate trap is not clogged, fill it as required and 

check for leaks.

-  Check that the safety valves are in good working order.

-  Bleed the complete system and refill to 1.5 bar if necessary.

  In the case of repeated fills, contact your installer.

-  Check the boiler’s pressure in maximum power mode.

If this value is very different from the original setting it may indicate 

an obstruction in the air intake ducts or flue gas exhaust pipes, or that 

the exchanger is clogged.
