1.

Ensure that all controls are calling for heat, and the selector

switch is in the central heating and hot water position (

 

 

 

 

 

).

 

 

 

 

 

The current boiler temperature is shown on the display.

 

 

2.

It is necessary to set the boiler to ‘Calibration Mode’.

 

 

3.

Turn both temperature control knobs fully anticlockwise,

 

 

then quickly turn the DHW temperature knob 1/4 clockwise

 

 

twice and back fully anticlockwise (Fig. 62).

 

 

4.

The display will now alternate between ‘SF’ and the current

boiler temperature and both green LEDs will flash (Figs. 63 &

64).

 

 

 

 

 

 

 

 

5.

Turn CH temperature control knob fully clockwise. As the

 

 

knob is turned the display will change from ‘0’ to ‘00’ (Fig. 65)

indicating maximum rate, then revert to ‘P’ alternating with the

current boiler temperature (Figs 66 & 67).

 

 

6.

With the boiler operating in the maximum rate condition

 

 

check that the operational (working) gas pressure at the inlet

gas pressure test point (Fig. 62a) is in accordance with B.S.

 

 

6798 & B.S. 6891.

7. Ensure that this inlet pressure can be obtained with all other

gas appliances in the property working.

Measure the Gas Rate

8.With any other appliances & pilot lights turned OFF the gas rate can be measured. It should be between:-

9.The ‘Calibration Function’ is active for 20 minutes unless the maximum CH temperature is exceeded.

10.The function can be disabled at any time by turning the DHW temperature knob.

11.Carefully read and complete all sections of the Benchmark Commissioning Checklist at the rear of this publication that are relevant to the boiler and installation. These details will be required in the event of any warranty work. The publication must be handed to the user for safe keeping and each subsequent regular service visit recorded.

12.For IE, it is necessary to complete a “Declaration of Conformity” to indicate compliance with I.S. 813. An example of this is given in I.S. 813 “Domestic Gas Installations”. This is in addition to the Benchmark Commissioning Checklist.
