USER’S GUIDE

———————————

USING THE BOILER

Make sure to have your installation inspected and maintained, if required, at least once a year by an approved 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 temperature drops below the set temperature.

GETTING FAMILIAR WITH THE CONTROL PANEL

The user must not attempt to gain access to the components inside the control panel.

• Master switch – Is used to turn the HeatMaster® on or off.
• Control thermostat – 60-90 °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 domestic hot water (DHW) and central heating, the control thermostat would normally be set at 80 °C to achieve optimum operating conditions.
• Summer/winter switch – Is used to turn the heating pump (if fitted) on or off.
• 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, then reinstall the cap. If the fault persists, turn the boiler off and call a service engineer.
• Daily timer – Allows the HeatMaster® to be turned on and off at specific moments of the day and operates on a 24 hour sequence. A series of white tabs are set around the timer, each tab corresponding to a 15 minute switching period. To set the timer, simply push outwards the number of tabs required for ON period.

Remember:      Tab in = HeatMaster® OFF
Tab out = HeatMaster® ON

• 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 0.1 MPa (1 bar), if it does, please see the ‘Heating System Pressure’ paragraph further in this section.
• 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.

HEATING SYSTEM PRESSURE

From time to time you may need to top up the heating circuit water level to get the required pressure in the system. The circuit 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 0.1 MPa (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 Starting up section – Filling the DHW and heating circuits).

If the pressure falls below 0.1 MPa (1 bar), the boiler water pressure switch will turn the boiler off until the pressure is restored

To restore the pressure, top up the heating circuit with water by opening the filling valve (A) of the boiler primary circuit and allow the system to fill. Once the pressure gauge of the boiler control panel indicates the required pressure, close the filling valve.

Safety valves
If water discharges from any of the safety valves, turn the boiler off and call a service engineer.

BURNER SAFETY MECHANISM

RESETTING THE OIL BURNER

• HeatMaster® 200 F
  The safety lockout indicator is located on the burner and on the control panel.

The red warning light indicates an operating fault.
Wait 5 minutes before resetting the burner. To reset: press the button located on the burner.

If the burner does not restart, call a service engineer after ensuring the fault is not due to a power failure or low oil level in the tank.

Note:
Given that regulations vary from one country to another, the table above is given by way of indication only.

Due to the high efficiency of our boilers, the flue gases are released at low temperature. As a result, there is a risk of condensation of the flue gases, which could damage some chimney constructions; to avoid this risk, it is strongly recommended to line the chimney. To prevent condensates to flow back into the boiler, we strongly advise to install a condensates collector. Please contact your installer for more information.

DHW CONNECTION

The DHW tank must be pressurized before putting the primary circuit (heating) under pressure.

The HeatMaster® boiler can be connected directly to the DHW circuit.

Flush the system before connecting the domestic hot water circuit.

The installation must be fitted with an approved safety group, comprised of a 0.7 MPa (7 bar) safety valve, a check valve and a shut-off valve.

During the heating process, the domestic hot water expands and the pressure increases. As soon as the pressure exceeds the safety valve setting, the valve opens and discharges a small quantity of water. Using a hot water expansion vessel (2 liters at least) will prevent this phenomenon and reduce the water hammer effect.

The hot water output may reach temperatures in excess of 60°C, which can cause burns.
ACV therefore recommends that you install a thermostatic mixing valve immediately after the appliance outlet.

If stop valves are used in the domestic hot water system, they can cause pressure changes when closed.
Use devices designed to reduce water hammer effect to avoid this phenomenon.

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.

EXAMPLE OF PARALLEL CONNECTION

Recommended for applications with a high constant flow.

EXAMPLE OF SERIES CONNECTION

Preferable for high-temperature applications with up to 3 units

EXAMPLE OF HEATING + STORAGE CONNECTION

Recommended for applications requiring a high peak flow.

HEATING CONNECTION

The DHW tank must be pressurized before putting the primary circuit (heating) under pressure.

Two couplings are installed at the back of the HeatMaster® , that can be used to connect a central heating circuit.
Connecting a heating system may reduce the domestic hot water performance.

EXPANSION VESSEL

The HeatMaster® 200 models are equipped with four 8 litre expansion vessels.
The expansion vessels are sized only for the “hot water” function. In the case of primary circuit connection, it is necessary to calculate the expansion capacity necessary for the total heating system volume (Refer to the expansion vessel manufacturer’s technical instructions for a broader explanation).

The pressure of the HeatMaster® expansion tanks must be adjusted to the same pressure as the heating circuit expansion tanks.

WARNING
The primary safety valve is supplied with a plastic tube connected to discharge outlet – this is for test purposes only and should be removed.
The safety valve should be connected to the sewer using a metallic pipe, e.g. copper.
