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 1bar, if it does the please see the 'Heating System Pressure' paragraph later in this section. 7. 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 The heating circuit may require a top-up of water. The pressure gauge, located beside the display, gives the pressure. In the case of repeated fills, contact your installer. The pressure of the primary circuit must be at least 1 bar and must be regularly checked by the end user. If the pressure falls below 0.5 bar, the low-water-level pressure switch locks the appliance until the pressure in the system returns to above 0.8 bar. The HeatMaster® 200 N / 200 F is fitted with a purpose-designed fill set (see Fig. A and B). Always make sure that the appliance is switched off when filling the system. To do this, turn the On/Off switch on the left of the control panel to Off. For more information, please ask your installer when delivering the system. The appliance is fitted with a safety valve. If the system pressure exceeds 3 bars, this valve opens and drains the water from the system. In this case, contact your installer. Fig. A (cover) Fig. B(rear panel) DESCRIPTION OPERATING PRINCIPLE The HeatMaster® is a high performance, direct fired hot water storage heater, which has indirect heat transfer due to its Tank-in- Tank construction. At the heart of the HeatMaster® is a stainless steel cylinder through which the flue tubes pass. This is surrounded by a mild steel shell containing the primary water (neutral fluid). The outer shell extends down to the combustion chamber and even around the flue tubes. The area of the heat transfer surface is therefore much greater than that of standard direct fired water heaters. A circulating pump fitted to the primary circuit moves the water around the tank, heating it faster and maintaining an even temperature across the primary jacket. The burner, either gas or oil, fires onto the primary water which indirectly heats the stainless steel cylinder containing the DHW. As with all Tank-in-Tanks, this is corrugated over its full height and suspended in the HeatMaster® by its hot and cold water connections. The cylinder expands and contracts during use and this, together with the fact that cold water does not come into contact with the intense heat of the burner flame, means that limescale buildup is prevented. This scale resistant feature, along with the corrosion resistance of stainless steel, eliminates the need for sacrifical anodes. The HeatMaster® has one very major advantage over other direct fired water heaters - because it heats the DHW with a primary circuit, this primary water can be used to provide central heating as well. By connecting two, three, four or more HeatMaster® together in a module, most hot water and heating demands can be met. Indeed, when used in conjunction with HR and Jumbo hot water storage tanks the HeatMaster can supply even the largest hot water requirement. Standard equipment The HeatMaster 200 has the following items as standard: - On/off switch - Summer/Winter switch - Control thermostat (60 - 90°C) -Thermal reset high-limit thermostat (95°C) - Manual reset high-limit thermostat - Hot water priority thermostat - Primary circulating shunt pump - Primary expansion vessels - Primary safety valve - Pressure and temperature gauge - Drain valve -Body completely insulated in rigid polyurethane foam PACKING The HeatMaster is delivered in separate packages. • Package No. 1: Foam-insulated body, hydraulic accessories, and control panel. • Package No. 2: Chimney reducing pipe. • Package No. 3: Wooden protective casing (jacket and accessory). • Package No. 4: “RIELLO” RG4S 396 T1 burner (HM 200 F only). DESCRIPTION CONSTRUCTION FEATURES Outer body The outer body, containing the primary water, is made from STW 22 carbon steel. TANK-IN-TANK heat exchanger The ring-shaped inner tank with its large heating surface for producing domestic hot water is built of Chrome/Nickel 18/10 stainless steel. It is corrugated over its full height by an exclusive production process and entirely argon arc welded by the TIG (Tungsten Inert Gas) method. Combustion gas circuit The combustion gas circuit is paint-protected and comprises: • Flue pipes Depending on output, HeatMaster® 200 models contain several steel flue pipes with an internal diameter of 64 mm. Each pipe is fitted with a baffle of special steel designed to improve heat exchange and reduce flue gas temperature. • Combustion chamber The combustion chamber on HeatMaster® models is entirely water cooled. Insulation The boiler body is fully insulated by rigid polyurethane foam with a high thermal insulation coeffi...
