16.2 - FITTING THE FIRE - 

references should be made to the drawings overleaf. 

 

! IMPORTANT NOTE !  

TAKE GREAT CARE WHEN WORKING INSIDE THE FIRE NOT TO MARK THE CERAMIC  

                                                          LINING PANELS.  

 

a.

  Using a Dust Sheet or equivalent protect the area around the Fire Installation. 

b. 

Remove the Fire from the box and lay it on its back.    

c. 

With the High Level and Thermatronic Control Systems remove the Control Heat Shield, which is secured with a single screw at the 
base of the fire on the left side. 

d. 

Now remove the Burner/Control Assembly by removing the 2 screws at the front of the fire taking care not to mark the liners. 

 

Slide the Burner Assembly forward and if the fire is fitted with the High Level or Thermatronic Control it will also be necessary to 
carefully slide out the Battery/Receiver Box and, in the case of the Thermatronic Control, carefully pull the Infrared Sensor off its 
Velcro Pad. 

e. 

Remove the Debris Plate at the back by removing the 4 screws allowing access through the Debris Opening for fitting the Gas  

      Supply.     

f. 

There are fixing holes in the front flanges which can be used if there is sufficient strong material for fixing, however we               
recommend the cable fixing system which is supplied to secure the unit into the fireplace. The cable fixing system will also pull the 
unit tight back into the fireplace to make a good seal. This is very important to ensure efficient and safe operation of the fire.    

g. 

There are a number of options for the Cable fixing system in different installation applications therefore please read the options 

 

first before proceeding.                                                                                                                                                                       

 

i. 

For Builders Opening applications and with reference to the diagram overleaf use the 2 cables supplied;1 to be used  

        each side of the unit.  Working 27mm up from the base of the Builders Opening and at 200mm centres drill the lower holes and  
        then at 455mm up from the base but at 250mm centres drill the upper holes. Secure the 4 Eyebolts supplied with the Raw plugs  
        to the back of the fireplace

.                                                                                                                                                                                              

 

ii.  

For Pre-cast Flue applications where the minimum depth is found it may be necessary to sink/rebate the Eye Bolts to ensure  

           the heads do not foul on the back of the fire.                                                                                                                                     

 

iii. 

For Chairbrick applications and to prevent the cables fouling on the Knee of the Chairbrick the Upper Eye Bolts should  

           be secured to the side walls of the Chairbrick. Positioned at same height as the standard option above but with the upper eye  
           bolts 100mm in from the front. See Diagrams below and on next page. 

 

 

IMPORTANT: 

ENSURE THE MATERIAL THE EYEBOLT/RAWPLUG IS FIXED INTO IS SOLID AND SOUND. If the fixing is not 

sound the Rawlplug/Eyebolt will be pulled out and the fire will not be sealed to the Fireplace Opening.  

 

Note: With the minimum depth fireplace enclosure it may be necessary to sink the Eye Bolt Heads into the Brickwork. 

 

h. 

With the Eye Bolts now in position there are 2 cable attachment tabs on the top of the main casing; 1 each side at the rear.    Feed 

a cable outward through each cable attachment point. 

i.

  Feed the cables though the eyebolts on either side and then through the holes in the back of the fire near the base. 

j. 

Slide the Fire 

part way 

into the fireplace

 

(leaving it sticking out approximately 50mm) ensuring the gas supply pipe and isolation/

pressure test elbow clears through the Debris Opening in the rear of the Fire. 

k. 

Slide the Fire fully home ensuring that the sealing strips on the rear of the Fire outer frame stay in position to make a seal against 
the fireplace back panel.  While sliding the unit into the fireplace opening pull on the excess cable.  

l.

  Locate the supply pipe into the slot in the Debris Opening and replace the Debris Plate. 

m.

  The Cable Fix Adjuster and Lock Screw can now be fitted onto the cable and tightened up to tension the fire back into the fireplace. 

The fire should be secure and not liable to movement.  

Surplus fixing cable MUST NOT be cut off and must be tucked back through the central hole in the Back of the Fire. 
This is particularly important with the Electronic Control Systems to keep the cables away from any electronics. 

n.

 

If any of the silicone sealing strips are not compressed and/or if there are gaps they must be filled with a suitable sealant,  

 

ideally high temperature silicone or fireclay. Refit the Burner/Controls Assembly with the 2 screws and with the High Level and 

 

Thermatronic Control System refit the Battery/Receiver Box at the left hand side, and then, for the Thermatronic, secure the  

 

Infrared Sensor onto the Velcro Pad. Then refit the Heat Shield above the Battery/Receiver Box and secure with the screw  

 

removed earlier. 

 

Important:

 Ensure the Red Bulb on the Thermatronic Infrared Sensor is facing Forward.                                                           

Important: 

Ensure the Heat Shield has been fitted with the High Level and Thermatronic Control Systems.   

o. 

Connect the isolation/pressure test elbow to the control valve and with it     
fully open check the joint for gas soundness. 

p.

  Check that all gas connections are sound. The appliance has been factory 

tested; however the connections may have been  

 

disturbed in transit or storage.                                                                                              

 

 

  ! TIP !   

Ensure the Red Bulb on the Infrared Sensor  is facing  

 

 

 

Forward as this can prevent the Handset from working. 

 
 

 

 

 

  ! IMPORTANT NOTE ! 

Always reseal the pressure test point  

 

and check that it is gas tight.

  

(This accounts for a lot of recalls.)
