The water heaters combine ACV's "Tank-in-Tank" concept with a double primarycircuit to reach the high performance of a TOTAL CONDENSATION, double-circuit water heater.All the WaterMaster® models are equipped with a high efficiency charging pump and with an ACV air/gas premix burner with low NOx emissions. During operation, the burner starts automatically as soon asthe water heater temperature gets lower than the preset temperature and stops as soon as the presettemperature is reached.The WaterMaster® series features a built-in frost protection mechanism: as soon as the flow temperature[NTC1 probe] drops below 7°C, the primary pumps are activated. As soon as the flow temperature is at5°C, the burner starts up until the flow temperature rises above 15°C. The pumps continue to run foraround 10 minutes. The function can be enabled or disabled through the installer menu. When the frostprotection is disabled, only the pumps operate.WATERMASTER® 25 - 35 - 45 OVERVIEW1235467101213141515161719 2122201811981. Concentric flue gas/air inlet box2. Flue gas exhaust tube3.
