    PREFACE These technical instructions contain useful and important information for the correct operation and maintenance of the Remeha HTG boilers, models Quinta 45 and 65. Read these instructions carefully before putting the boiler into operation, familiarise yourself with it’s control functions and operation, strictly observing the instructions given.

  • Page 6: General Description Of The Boiler

    GENERAL DESCRIPTION OF THE BOILER The Remeha Quinta 45 and 65 are wall hung condensing boilers which may be also installed free standing on a suitable frame (option). The one piece cast aluminium heat exchanger and other major components are contained within a sealed air box. This forms the main boiler casing with a removable front section for maintenance purposes.
