MODENA S HE 2. Installation 2.1 General Instructions This unit must only be used for its intended purpose. This unit is designed to heat water to a temperature below boiling point and must be connected to a heating system and/or a water supply system for domestic use, com- patible with its performance, characteristics and heating capacity. -
Page 8: Place Of Installation
MODENA S HE 2.2 Place of installation The combustion circuit is sealed with respect to the place of installation and therefore the unit can be in- stalled in any room. However, the place of installation must be sufficiently ventilated to prevent the creation of dangerous conditions in case of even slight gas leaks. - Page 9 MODENA S HE Shutoff valve kit The shutoff valves supplied (see fig. 10) must be installed between the boiler and heating system to allow the boiler to be isolated from the system if necessary. For installation, follow the instructions contained in the kit.
