Combustion gas circuit The combustion gas circuit is paint protected and comprises: • Flue pipes HeatMaster 71/101 models contain 8 steel flue pipes with an internal diameter of 64 mm. Each pipe is fitted with a turbulator of stainless steel designed to improve heat exchange and to 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 coefficient, sprayed on without the use of CFCs. Casing The boiler is covered by a steel casing which has been scoured and phosphated before being stove enamelled at 220 °C. Burner 71 and 101 models are always delivered with ACV BG 2000-M 71 and 101 air/gas premix burners.

The MCBA has three levels of settings : manufacturer, installer and user. There are three temperature detectors located in the primary and secondary circuits. It provides two operating modes. 1. Heating mode Temperature set by the user at between 60 and 90 °C. • Differential “ON”, burner starts. • Differential “OFF”, burner stops. • PI (Proportionnel Integral) regulator in “heating” mode. • The regulator compares the primary temperature with the setting and modulates. The room thermostat detects the heating demand 2. Hot water mode (with hot water priority) The detector located in the secondary tank detects the hot water demand. When a draw-off is detected the controller goes to “hot water demand” mode: • The primary shunt pump starts. • The heating pump switches off. • The burner starts and the controller uses the data from the primary detector to control modulation. User-accessible parameters 1. “Hot water” setting adjustable from 20 to 90 °C. 2. “Hot water” mode: ON/OFF. 3. “Heating” mode: ON/OFF. 4. “Heating” setting adjustable from 60 to 90 °C. Parameters accessible in servicing Main default settings: - Hot water priority active. - Heating demand detection by room thermostat. -A single heating circuit. An access code is required for “service” access. For more technical information, contact your ACV dealer. ...
