    PREFACE These technical instructions contain useful and important information for the correct operation and maintenance of the Remeha HTG boiler, model Quinta 115. Read these instructions carefully before putting the boiler into operation, familiarise yourself with its control functions and operation, strictly observing the instructions given.

  • Page 6: General Description Of The Boiler

    Remeha Quinta 115 GENERAL DESCRIPTION OF THE BOILER The Remeha Quinta 115 is a wall hung condensing boiler 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.

  • Page 8: Operating Principle

    Remeha Quinta 115 2.2 Operating principle Combustion air is drawn into the closed air box by a variable speed fan, through the air inlet connection from the plant room (open flued) or from outside via the concentric flue system (room sealed). On the inlet side of the fan is a specially designed venturi which is connected to the outlet side of the gas combi block.
