Page 9: Installation
DOMIcompact F 24 D 2. INSTALLATION 2.1 General Instructions This device must only be used for the purpose for which it is specially designed. This unit is designed to heat water to a temperature below boiling point and must be connected to a hea- ting system and/or a water supply system for domestic use, compatible with its performance, characteristics and its heating capacity. -
Page 10: Boiler Location
DOMIcompact F 24 D 2.2 Boiler location The boilers combustion chamber is sealed off from the installation room. The installation room must be sufficiently well ventilated to prevent any dangerous conditions from forming in the event of even slight gas leakage. This safety standard is required by the EEC Directive no. 90/396 for all gas units, including those with a so-called sealed chamber. - Page 11 DOMIcompact F 24 D Make Up Water Provision must be made for replacing water lost from the sealed system. Reference should be made to BS6798, for methods of filling and making up sealed systems. There must be no direct connection between the boiler's central heating system and the mains water supply.
