2. - LIGHTING & CONTROLLING THE FIRE 

General 

The fire is available with 4 Control Options: a Manual Control (Fire is lit and adjusted manually), a side fitted 2 Button High Level Control 
(Fire when lit can be controlled with the Push Buttons), a side fitted 3 Button High Level Control (Fire can be lit and controlled with the Push 
Buttons) or Thermatronic Radio Frequency Electronic Control System (Fire is lit and operated with the Handset). 
Some Models also have a Coal / Coke Effect Lever System see 2.7  

2.1 - LIGHTING & CONTROLLING THE FIRE – MANUAL CONTROL  

Remove the Ash Pan Cover to get access to the Control Knob used to operate the Fire.   
a. Switching On/Ignition. 

Depress the control knob & turn counter clockwise. Gas will flow to the Pilot Burner (Pilot Burner is visible 

    looking down through the glass at the left side), the Piezo Igniter will give off first one, then, as you turn, a second high voltage  
    spark & the Pilot Burner will Light. (More than one attempt may have to be made on first lighting.) 
    Keep the Control Knob depressed for approximately 10 seconds to heat up the Thermocouple. 
    Turn the Control Knob fully counter clockwise to release gas to the Main Burner.  

b.

 

Control of Gas Flow.

 Turning the Control Knob clockwise reduces the gas flow from Maximum to the Pre-Set Minimum Setting. 

    Turning between Maximum & Minimum does not actuate the Piezo Igniter. The Control Valve can only be turned on to the Pilot  
    setting by depressing the control knob & turning it to the pre-selected pilot position. 

c. Switching Off. 

Press the Control Knob in at the Pilot Position & turn Clockwise to Off. 

 

2.2 - LIGHTING & CONTROLLING THE FIRE –  2 BUTTON HIGH LEVEL CONTROL  
Requires Pilot Ignition First.  

The side trim positioned High Level Control System is a battery operated gas fire control system that uses push buttons linked to a main 
control at the base of the fire. This control system is used with an oxypilot and has all the safety features required by law and CE approval. 
Once the fire is lit by operating the Control behind the Ash Pan Cover the settings can be controlled by the 2 Push Buttons on the upper 
right side of the Trim. 

 

Using the System 

Remove the Ash Pan Cover to get access to the Control Knob used to operate the Fire.   
a. Switching On/Ignition. 

Depress the right control knob & turn counter clockwise. Gas will flow to the Pilot Burner  

    (Pilot Burner is visible looking through the fender, under the flue bed, at the front right hand corner), the integral Piezo 
    Igniter will also give off a high voltage spark & the Pilot Burner will Light. (More than one attempt may have to be made 
    on first lighting.) 
    Keep the Control Knob depressed for approximately 10 seconds to heat up the Thermocouple. 
    Turn the Control Knob fully counter clockwise to release gas to the Main Burner.  

b.

 

Control of Gas Flow Using the Side Trim Push Buttons.

 Press the lowest button to gradually reduce the gas flow  

    from Maximum to the Pre-Set Minimum Setting, you will hear the motor turning the control. Keeping the Lower Button 
    depressed will eventually turn the main burner off  leaving the pilot alight. 
    To relight the main burner or increase the heat setting from low, press the Upper Button to achieve settings between  
    low and high. When the fire has reached high the control under the fire will click repeatedly, release the button. 

c. Switching Off. 

Remove the Ash Pan Cover and turn the right Control Knob Clockwise to Off.    

d. Battery Replacement . 

The Batteries should be replaced every season, you will notice they need changing as  

    gradually the Push Buttons cease to operate the Control. 

e. Changing the Batteries

. Remove the Ash Pan Cover and you will find the Battery Box on the left hand side.  

    Pull towards the front taking care not to strain the connecting wire. Using a small screw driver remove the screw, slide 
    off the cover and take out the Batteries. Replace with 4 x AA good quality alkaline batteries, operate the Push Buttons 
    to check the Batteries are fitted correctly.   
 

Note: Only Change The Batteries When The Fire Is Cold  

 

 
 

2.3 - LIGHTING & CONTROLLING THE FIRE - 3 BUTTON HIGH LEVEL CONTROL  
The 3 Button High Level Control Lights the Pilot and Controls the Fire.  

The side trim positioned High Level Control System is a battery operated gas fire control system that uses push buttons linked to a main 
control at the base of the fire. This control system is used with an oxypilot and has all the safety features required by law and CE approval. 

Note: The Centre Button is both the Ignition and Off Button.   
Using the System 

a. Ignition. 

Simultaneously press and hold the Centre Button until a short acoustic signal confirms that the sequence  

     has begun, then release the buttons.  Continuous audible signals confirm that ignition is in progress. When pilot ignition is 
     confirmed the motor will open the valve to maximum flame height – this takes about 30 seconds. 
     When the fire is first operated and on occasions when the fire has not been used for some time the Pilot may not light 
     after pressing the Centre Ignition Button even though the acoustic sound may have been heard. On these occasions it may 
     be necessary to repeat the sequence a number times to light the pilot. This is quite normal. 

b. Flame Height Adjustment. 

Press the bottom down arrow button until the flame height is at the desired position.   

     If you try to go beyond the preset low flame minimum height the fire will turn off leaving the pilot burner alight  
     (This is the standby position).  You will learn from experience the minimum preset flame height. 

c.

 

Relighting the Fire. 

To relight the fire from the standby position, or to increase the flame height from low flame, press  

     the top up arrow. 
     Please note that you can have the flame height anywhere between maximum and preset low.   
     For fine adjustment simply tap the up or down arrows. 

d. Switching Off. 

Press the centre button.
