Ravenheat CS 80 T, Instructions For Use Installation And Servicing

6

It is the law that all gas appliances are installed by 
a competent person, in accordance with the gas 
safety installation and to the current Gas Safety   
(Installation and Use) Regulations B.S.5440:2-(2000).

All registered installers carry a  Gas Safe Register ID card 
and have a registration number. Both should be recorded in 
your boiler Log book. You can check your installer’s 
registration at  www.gassaferegister.co.uk.

ESCAPE OF GAS

    Should a gas leak be suspected, contact your gas 
    supplier without delay.

    GAS EMERGENCY NUMBER: 0800111999
    
    Do NOT search for gas leaks with a naked fl ame.

WARNING: 

This appliance must be earthed.  

1.1      

INTRODUCTION

       Please carefully read the information given in this 

                  booklet to help you gain maximum control from your 
                  appliance with minimum trouble and cost.

Your Ravenheat Condensing Low Nox combination boiler 

                  has  been designed to supply your Central Heating and 
                  Domestic Hot Water directly from one unit. 
                  When Central Heating is operating, the circulation will be 
                  interrupted when Domestic Hot Water is being drawn off 
                  (domestic hot water has priority).
                  This will normally not affect the level of Heating.

         
         PLEASE NOTE:

Due to the high effi ciency of this appliance and resulting 

                  low fl ue gas exhaust temperature a white plume of 
                  condensation vapour (cool steam) will be emitted from the 
                  fl ue outlet  terminal, this is quite normal. It will be 
                  particularly evident during periods of low outdoor 
                  temperature or when the boiler is working at its optimum 
                  performance (Plume Management kits are available on 
                  request).

                 IMPORTANT:
                 

In the unlikely  event of the exhaust fl ue gases exceeding 

                 the overheat temperature setting, the boiler operation will 
                 be stopped to prevent damage to the appliance.

     1.2 

CLEARANCES AROUND THE APPLIANCE

             Side clearance:

             The position of the appliance must provide a  
             minimum  clearance of only 5 mm as the side panels 
             do not require removing for servicing.            

However, if the option is preferred to remove the   

             panels then a minimum clearance of 55 mm is 
             required.

             Top clearance:

             The top clearance should be a minimum of 
             125 mm.

             Bottom clearance:
             

A minimum bottom clearance of 80 mm is 

A minimum bottom clearance of 80 mm is 

             required between the appliance 

             required between the appliance and any surface,
             though 150 mm is preferred whenever 
             possible.

Front clearance:

             A minimum of 450 mm is required in front of
             the appliance for access during servicing, the
             front clearance can be reduced when installed 
             in a cupboard to 25 mm from the access door.
