Page 25: Introduction
Introduction About the water heater The EcoSable water heater is intended for heating water for sanitary purposes. The EcoSable is a condensing gas–fired storage water heater with a fan in the air intake. The flue gasses transfer their heat to the water through an efficient heat exchanger. The water heater has a concentric venting connector and can function as an open or as a room-sealed water heater. - Page 26 Fig. EcoSable water heater 1. Water inlet 2. Heat exchanger 3. Water outlet When the temperature is too low, the water heater starts a operating cycle: The controller detects a "heat demand". The fan starts pre-purging. The air proving switch closes when the air pressure differential is sufficient. The spark plug is activated.

Safety Safety instructions For safety instructions on the use of the water heater, refer to Safety (see 2) in the User part of this manual. Warning Installation, maintenance and service must be carried out by a qualified engineer in compliance with the general and local regulations imposed by the gas, water and power supply companies and the fire brigade. -
Page 28: Instructions On The Water Heater
Caution To prevent that you damage the components of the water heater, make sure that it is completely stopped operation before you isolate the water heater from the mains (see 4.2.2). Wait 1 minute after you switch the water heater to OFF mode. Note Any leakage from the tank and/or connections can cause damage to the immediate environment or floors below the level of the boiler room. -
