2.7.- COAL-COKE EFFECT LEVER  

Note 

: This Feature is 

not used 

on either the Natural Gas Pebble Fire or the Propane Fires.  

 
The Natural Gas Coal Fire Model is fitted with a control lever to enable different flame effects to be created. With the lever pushed-in 
the flames will be quite yellow replicating a Coal Fire Flame Effect. With the lever pulled-out the flames will be more blue replicating 
a Coke Fire Flame Effect. 

The Coke Fire Flame Effect setting provides the hottest and most efficient Heat Output for the Fire

 
a.

  Remove the Ash Pan and at the upper centre of the opening you will see the black Coal-Coke Lever. Push the lever in for the 

 

Coal Effect setting, pull the lever out for the Coke Effect setting. 

 

  ! IMPORTANT ! 

On the Coal Setting, the Yellow Flames may cause some sooty deposits to form and to reduce this we 

 

 

 

 

 

recommend changing to the hottest Coke Setting.  

 

  ! TIP !  

On the Coke Setting the Fire Produces More Heat and is operating at its most Efficient Heat Setting. 

 
 

3. - CLEANING THE FIRE 

a.

  Allow to cool before cleaning. 

b. 

The outer surfaces of the fire can be cleaned with a damp cloth and lightly polished with a duster, do 

not

 use abrasive cleaners. 

 

For Stainless Steel finishes we recommend a small amount of Baby Oil.    

 

 

4. - SERVICING 

a.

  The fire should be Serviced Annually in accordance with the Gas Safety & Uses Regulations. 

b.

  This fire contains no User Serviceable Parts apart from the batteries which are only used with the High Level and Thermatronic 

Control System options. 

c.

  Servicing must be carried out by a Registered Installer. 

d.

  For Servicing or Spare Parts contact your Installer quoting the Fire Name, Model and Serial Number, which can be found on the 

Data Badge. To find the Data Badge/Plate; with the fire cool remove the Ash Pan Cover, the Data Badge can be found at the 
base next to the Control Knob. 

e.

  In the event that the fire shuts down due to any reason, attempt to restart it. If there is a continuing problem, call in a properly 

qualified specialist engineer. 

f.

  The Matrix in the fire is a Moulded Ceramic Fibre component incorporating Silicone Binders and you may notice that it develops 

  

cracks during operation.  This is natural shrinkage caused by exposure to high temperatures and is quite normal for the material 

  

and will in no way affect the operation of the fire.
