GENERAL

 

a. 

This fire must be installed by a properly qualified (in accordance with National & Local Regulations) Installation Engineer. 

b. 

The connection of this appliance, and ventilation requirements (if any) are to be according to National & Local Codes. 

c.

  The chimney should be swept before the appliance is installed. 

d.

  Open fires are a hazard; it is recommended that a guard be fitted to provide protection for children, the elderly or infirm. (See 

National & Local Regulations if any.) 

e.

  This appliance is intended for decorative purposes only. 

f.

  Do not throw rubbish on, or attempt to burn any materials on this appliance. Any debris or foreign matter must be removed 

from the fire. 

g.

  The appliance should be serviced by a qualified engineer every 12 months. 

h. 

The  Thermatronic  Control  System  is  a  battery  operated  gas  fire  control  system  that  uses  a  microprocessor  to  provide  the 

working sequences needed by the fire, and when used with an oxypilot has all the safety features required by law and CE 

approval. 

i. 

Commands are accepted by the microprocessor when buttons are  pressed.  An audible beep means that the command is 

received, and the push button should immediately be released. 

 

 

 

 

 IMPORTANT NOTES 

a. 

This appliance is fitted with an oxygen depletion sensing system, which automatically shuts off the gas supply to the  main 

burner if the oxygen level in the room is depleted, due to a lack of primary air, or obstructed flue that would lead to incomplete 

combustion of the gas. 

b. 

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. 

c

.  There are no user replaceable parts in this appliance except the 4 # AA batteries. 

d.

  The Fireboxx is supplied with batteries in a separate box that has a long lead which plugs into a socket on the standard 

  electronics/battery box.   

e

.  This battery box is accessed at the left hand end of the Fireboxx  (beneath a removal cover plate)  and positioned with the 

connection lead connector at the top. Ensure that the lead wire does not contact the end of the burner pan by tucking the lead 

wires between the battery box and the left hand end of the Fireboxx, as shown on the drawing on page 6. 

f

.  On no account put batteries into the battery compartment of the receiver box. They must only be placed in the battery box 

situated at the left hand end of the Fireboxx, as shown on the drawing on page 6. 

g. 

Regularly inspect the purpose provided room ventilator (if fitted) to check that it is free from any obstruction. 

h

.  The chimney should be regularly checked to ensure that all the products of combustion are entering the flue & that there is no 

build up of soot. If there is, the appliance must be cleaned. 

i

.  Do not cover the ventilation holes in the top plate grille with fuel bed or any other material. 

 

 

IMPORTANT NOTE 

Simulated crushed rock, simulated pebbles, simulated 

logs, or simulated driftwood, manufactured from 

special materials, are supplied with this appliance. 

Do not use real crushed rock, pebbles, logs or 

driftwood, as this is dangerous. If the simulated 

crushed rock, simulated pebbles, simulated logs or 

simulated driftwood need renewing please obtain 

suitable replacements from a  

Nu-Flame stockist.
