Page 8: Installation
Maxima 35 S 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 9: Boiler Location
Maxima 35 S 2.2 Boiler location The unit’s combustion circuit 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 10: Boiler Water Connections
Maxima 35 S 2.3 Boiler water connections The heating capacity of the unit should be previously established by calculating the building’s heat requirement according to current regulations. For good operation and long life of the boiler, the plum- bing system must be well proportioned and always complete with all those accessories that guarantee regular operation and running, room thermostat, trv’s and automatic bypass etc. - Page 11 Maxima 35 S The Isolation valve kits shown in fig. 4 are supplied as standard.
