FILLING THE HOT WATER AND HEATING CIRCUITS

IMPORTANT

Hot water tank must be pressurised before the heating circuit is filled.

1.Close the primary circuit filling valves (A and B)

2.Open the stop valve (1) and the draw-off tap (8). Fill the tank with the water from the tap; close the draw-off tap (8).

3.Fill the primary (heating) circuit by opening the valves (A and B) and pressurising to 1 bar.

ACV BG 2000-M MODULATING PREMIX GAS BURNER

Description and operating method:

The BG 2000-M modulating burner's output is constantly adjusted to suit the fluctuating demand for heat, thus optimising operating efficiency.

The gas tube is covered with a metal fibre (NIT), which, in addition to its outstanding heat-exchange properties, increases its life.

The main parts are a venturi and a valve, a unit developed specially by Honeywell for low NOx air/gas premix burners with automatic ignition and flame detection by ionisation.

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 blockage in the chimney 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-M burner on the HeatMaster® 201 is controlled by an MCBA controller (Honeywell), which controls the safety of operation of the burner and its modulation according to the temperature.

The BG 2000-M burners are factory-set for natural gas.

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 = 10 m and 2 bar = 15 m.

6.Check that the electrical connection and boiler room ventilation conform to the relevant standards.

7.Switch the on/off switch to the ON position.

8.Set the temperature values (see page 17).

9.Check the gas supply pressure (see page 13).

10.When the burner is on, check that the flue gas discharge pipes are completely gas tight.

11.After operating for five minutes, turn off the boiler and drain the heating circuit again, maintaining a pressure of 1 bar.

12.Turn the appliance back on and check the combustion (see page 13).

201 specifications

The Heatmaster 201 is an advanced wood stove designed for optimal heating efficiency and user comfort. This high-performance heating solution incorporates innovative technologies that enhance its functionality and appeal, making it a popular choice for homeowners seeking a reliable and eco-friendly wood-burning option.

One of the standout features of the Heatmaster 201 is its robust construction. Built from high-quality materials, it ensures durability and longevity, capable of withstanding the rigors of regular use. Its heavy-duty steel body provides excellent heat retention, allowing for a more prolonged and even distribution of warmth throughout the space.

The Heatmaster 201 employs a clean-burning technology that helps reduce emissions, making it an environmentally friendly choice. This technology not only minimizes the environmental impact but also improves fuel efficiency. It burns wood more completely, resulting in less creosote buildup in the chimney, thus reducing the risk of chimney fires and the need for frequent cleaning.

This stove features a large firebox, allowing for longer burn times. Users can enjoy extended periods of heat without the constant need to reload with fuel. The design also accommodates various log sizes, providing flexibility in fuel choices. This versatility makes it easier for homeowners to utilize available wood resources effectively.

Moreover, the Heatmaster 201 includes an airwash system that keeps the glass door clean, allowing for an unobstructed view of the fire. This not only enhances the aesthetic appeal of the stove but also ensures that users can monitor the fire's activity without the distraction of soot accumulation.

The installation of the Heatmaster 201 is simplified further by its compatible venting options. Whether through a chimney or direct vent systems, users can choose the setup that best suits their home layout. Additionally, safety features, including a secure ash pan and heat-resistant door handles, ensure safe operation.

In conclusion, the Heatmaster 201 is a remarkable wood stove that combines durability, efficiency, and user-friendly design. With its clean-burning technology, robust construction, and ease of maintenance, it stands out as an exceptional choice for those looking to enhance their heating solutions while minimizing environmental impact.
