SERVICING INSTRUCTIONS

        Ravenheat is a member of  the  Benchmark 
        initiative and fully supports the aims of the 
        programme. 
        Benchmark was instructed to improve the  
        standards of installation and commissioning 
        of central heating systems in the UK and 
        to encourage the regular servicing of all 
        central heating systems to ensure safety and 
        efficiency.

        During routine servicing, and after any 
        maintenance or change of part of the 
        combustion circuit, the following must be 
        checked:
       - The integrity of the flue system and the 
          flue seals.
       - The integrity of the boiler combustion 
          circuit and the relevant seals.
       - The operational dynamic (working) gas 
          inlet pressure at maximum rate.
      -  The gas rate.
      -  The combustion performance (Refer to 

(Refer to 

          table 10 and page 64).

          table 10 and page 64).

7.1  BOILER FROST PROTECTION

      The appliance has a built in frost protection 
      device that protects the boiler from freezing. 
      With the gas and electric supplies ON and 
      irrespective of any room thermostat setting, the 
      frost protection device will operate the pump 
      when the temperature falls below 10 °C and 
      will operate the burner when the temperature 
      falls below 5°C.
      The burner will switch off when the temperature 
      reaches 27 °C. When the frost protection 
      device operates “AF” is displayed on the digital 
      display.

IMPORTANT NOTE

:

The system should be protected by incorporating a 
system frost thermostat.

               To ensure continued efficient operation of 
               the appliance it is necessary to carry out 
               servicing and cleaning at regular 
               intervals.
 

The frequency of servicing and 
cleaning will depend upon the particular 
installation conditions and usage but in 
general, once a year is advisable.

WARNING:
Before the start of any servicing or
replacement of components always
isolate the electricity supply to the 
appliance and always turn off the 
appliance gas supply at the gas 
service cock.

The data badge is positioned low on the 
inside left panel.

-   The following notes apply to the 

appliance and its controls but it should 
be remembered that attention must 
also be paid to the heating and hot 
water circuits with special attention to 
radiator valves, thermostats, clocks, 
leaking hot water taps etc.

-   Where it is necessary to replace 

a gasket that relies on adhesive 
for securing - this adhesive will be 
supplied with the gasket as a spare 
item.

-  In all cases prior to servicing, remove 

the front panel of the case. Operate 
the  appliance by turning the hot 
water services on to a high water 
flow. Measurement of the products 
of combustion can be achieved 
by connection of a probe to the 
combustion analyser test point.

Combustion testing must be carried out  by competent person    

                                    using a combustion analyser conforming to BS7927.
