MODENA C 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.
MODENA C 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.

MODENA C HE Condensate drain The condensate should be run inside as far as is practicably possible. For that purpose, use a pipe of at least 22 mm supplied with diameter and a trap with flexible connection the unit to facilitate connection of the condensate drain pipe. The pipe must be in solvent weld plastic and not in copper, since the condensate has a pH of 4 (slightly acid).
All adjustment, conversion, startup and maintenance operations described below must only be carried out by Qualified Per- sonnel (meeting the professional technical requirements prescribed by current regulations). FERROLI declines any liability for damage and/or injury caused by unqualified and unauthorised persons tampering with the unit.
MODENA C HE 3.2 Start-up Checks to be made on initial start up, and after all maintenance operations that involved disconnection from the systems or an operation on safety devices or parts of the boiler: Before lighting the boiler • Open any valves between the boiler and the system.
