Ensure  that  once  the  coals  have  been  laid  there  are  even  gaps  between  them.  If  a  coal  or  coals 
appear  to  fit  awkwardly  in  certain  positions  then  it  may  be  necessary  to  swap  these  around  with 
others or relocate them by rotating to achieve an evenly spaced coal lay. This will ensure an even 
flame spread when the fire is lit. 

Commissioning

 

-  Turn gas supply OFF, remove inlet pressure test point screw, connect a suitable pressure gauge.  
-   Turn gas supply ON - check installation for gas soundness. 

Burner Operation (Manual / Comfort Control) 

-  Push the control knob in and turn anti-clockwise until the spark igniter operates. 
-  Repeat this operation to purge any air from the system until the pilot ignites. 
-  Keep the knob pushed in for 10-12 secs to energise the flame failure device. 
-  Release the knob, the pilot should remain alight.

 

-  Depress the knob slightly and turn anti-clockwise as far as it will go to the MAX position. The fire 

should light (Unless comfort controller fitted). 

-  If Comfort Control fitted press LOW on switch panel then ON. The fire should light. Press HIGH 

on the switch panel. 

-  Check the setting pressure - 20.0 mb ± 1.0 mb (cold) MAX. 
-  Check for gas soundness at all joints with leak detection fluid. 
-  Turn the appliance OFF 

Ɣ

 and turn off the gas supply to the fire. 

-  Remove the pressure gauge and replace the pressure test point screw. 
-   Check the pressure test point for gas soundness with the gas supply turned ON. 

Burner Operation (Remote Control)

 

-  If Remote Control fitted, point the handset to the sensor on the front of the fire. Push and hold the 

two ignition buttons together, on the left hand side of the handset. The fire will give out a beep 
sound and you can release the buttons. After a few seconds you will hear the clicking spark to the 
pilot  light.  Once  the  pilot  is  lit  the fire main burner  will  come  on  to  the  high position (this whole 
process will take no more than 20 seconds).  

-  If the burner fails to light repeat this operation to purge any air from the system until the pilot and 

main burner ignites. 

-  Check the setting pressure - 20.0 mb ± 1.0 mb (cold) MAX. 
-  Check for gas soundness at all joints with leak detection fluid. 
-  Turn fire off by pointing the handset at the sensor and push the top left button. The fire will go out.  
-  Remove the pressure gauge and replace the pressure test point screw. 
-   Check the pressure test point for gas soundness with the gas supply turned ON.
