INSTALLATION :
Prepare the fireplace and chimney as previously described.
Unpack the fire. For ease of installation remove the burner assembly. Unscrewing the two
retaining screws at the base of the front support legs can do this. Remove the complete burner
assembly and rear baseboard.
Within the base of the box, there are three mounting holes. Place the box centrally into the
fireplace opening; making sure the box is square and level. Mark through the three mounting
holes and remove the box. Using a 6mm masonry drill, drill and plug the fixing holes.
Lay the gas supply pipe in the fireplace opening. A means of isolating the gas supply other than
the appliance control valve should be fitted in the gas supply line. The inlet pipe to the appliance
should be 8mm O.D rigid or semi-rigid tubing. If the supply pipe is more that 1.5 meters in length
then the gas supply pipe diameter should be increased to a minimum of 1.5mm from that point.
Access through the outer casing of the appliance is through the rear or side access holes. The
gas supply pipe should be positioned within the fireplace as shown in fig No 21. A separate hole
is made through the fibre and the tube passed through. The tube must be sealed around the
hole using suitable silicon mastic, flexible fire cement or other approved method.
The box is repositioned within the fireplace, sealed to the opening, and secured to the hearth by
means of fixing screws. Check seal around the edges.
Replace the burner assembly, rear base board and make good the final gas connection into the
main control valve. Finally check the whole system for gas soundness.

Ensure that all doors and windows of the room are
closed. Remove the ash pan cover and light the fire as
previously described. Replace the ash-pan cover and
leave the fire on maximum gas rate for ten minutes.
Hotboxes:
Insert a smoke match as shown in Fig No.29. Ensure
that the smoke is being drawn into the opening, along its
full width, particularly the corners of the opening. If in
doubt repeat the procedure after a further ten minutes.
If there is a fan in a nearby room then the test must be
repeated with the fan turned on, any interconnecting
doors between the fire and the fan location must be left
open.
If spillage is detected the chimney or flue may be faulty. The fault must be corrected before leaving the fire
installed. If the fault cannot be corrected turn off the appliance and disconnect the gas supply to the fire, and
seek expert advice.

SPILLAGE MONITORING SYSTEM :
The appliance is fitted with an oxygen depletion pilot In the event of flue blockage or non-evacuation of
combustion products, the appliance will automatically shut down.
The pilot assembly is none-adjustable and is pre-set. It is IMPORTANT that this is not
altered, adjusted or by-
passed in any way. If replacement is required, only original manufacturer’s parts should be used.
If the appliance does shutdown automatically leave for 3 minutes before relighting. If however automatic
shutdown still occurs switch the fire OFF, disconnect the gas supply to the fire and seek expert advice.
INSTRUCT THE USER :
Leave these instructions with the user, and explain how to light and operate the appliance, including how to
light the appliance using a long lighted spill.
Impress on the user, that the coals must be located in accordance with the instructions, and a CORGI
registered engineer to ensure safe operation should service the appliance at regular intervals.
Advise the user that any smell coming from the fire on initial lighting will quickly disappear after a few hours.
SERVICING
:
It is recommended that the fire is inspected/serviced on an annual basis by a CORGI registered engineer. The
service engineer should replace any damaged or broken coals as necessary.
Before commencing any work isolate the gas supply to the fire. After any work ALWAYS TEST FOR GAS
SOUNDNESS.
SERVICING PROCEDURE :
Ensure that the fire is switched OFF and is cold before servicing commences. Isolate the gas supply to the
appliance. Carefully remove all coals from the fire and inspect for damage, remove the fire front and coal
guard.
Using a soft brush remove all soot and debris deposits from the main burner and pilot. Check condition of the
main burner gauze.
If parts require replacing then removal of the burner assembly is carried out as follows:-
Disconnect the gas at the inlet to the appliance. Remove the 2 screws at the base of the burner front support
legs and remove complete burner assembly. Remove the rear baseboard, check for damage and replace as
necessary.
Check the condition of the thermocouple and spark ignitor.

Users Instructions (All fires)
This leaflet has been prepared to help you use and
understand your gas fire.
Please read the instructions carefully before you begin
using this fire and keep the leaflet handy for future
reference.
OPERATION OF THE FIRE
To obtain access to the controls remove the ash-pan cover. The gas control valve cover is marked with the
following positions, Off, Pilot and a graduated section for Minimum and Maximum gas rates Fig.31. The
control knob point should be placed next to the position required.
TO LIGHT THE FIRE :
Ensure that the control knob is in the OFF position. Fully depress the control knob and keep in, turn
anticlockwise, you should feel some resistance to the knob turning; this is the piezo spark generator being
activated. Upon reaching the pilot position you will here a click, as the piezo spark igniter operates, the pilot
should light. If the pilot fails to light repeat the operation.
Once the pilot has lit, hold the knob in for a further 10-15 seconds to establish the pilot. When the knob is
released the pilot should remain alight. If the pilot fails to remain alight repeat the procedure but hold the knob
in longer to allow the pilot to establish.
If however you are experiencing difficulty in lighting the pilot, then the pilot can be lit manually by the use of a
long lighted spill. Place the lighted spill in the area of the pilot, turn the knob to the pilot position and hold in,
the pilot will then light off the lighted spill.
The gas control valve is fitted with a piezo spark generator, which when activated creates a spark at the pilot
head. If the main burner or pilot burners are extinguished for any reason, DO NOT ATTEMPT TO RELIGHT
THE PILOT FOR THREE MINUTES.
TO ALTER THE HEAT SETTING
With the main burner lit the heat setting is variable between high and low, and at any required setting between.
See fig 31.
TO TURN THE FIRE OFF :
To turn the fire off, turn the control knob to the minimum position, slightly depress the knob and continue
turning clockwise until the pilot position is reached. The fire will go out and the pilot light will remain lit, and
may, if required be left on for intermittent use.

To turn the fire off completely keep the control knob depressed and continue turning clockwise until the off
position is reached. (See fig 31).
INITIAL OPERATION
Due to newness the fire may give off a slight smell for a short period after commissioning, this will disappear
after a few hours operation.
IMPORTANT NOTES
Whilst the fire meets the required safety standards additional guarding is recommended to give protection to
the young, elderly, and the infirm. Fitting a fireguard, which complies, with current regulations can provide
extra security.
The appliances have been designed to meet the requirements of EN509, and other relevant safety standards,
but during use parts of the Hotbox casing may become HOT. It is therefore recommended that a suitable
fireguard to BS6539 “Fireguards for use with solid fuel appliances” be used where the very young or infirm are
concerned.
Never allow rubbish to be thrown on to the coal bed of the appliance, or otherwise disturb the fuel bed. Any
hearth at the front of the fire should never be covered with combustible flooring or materials.
The chimney should be checked annually to ensure continued clearance of combustion products, and that
there is no excessive build up of soot. It is recommended that the fire also be inspected/checked on an annual
basis by a CORGI registered engineer.
CLEANING
Cleaning should be carried out only when the fire is turned off and Cold. If the fire has a back box, the
brassware on the fire may be cleaned using an appropriate metal polish, care should be taken not to let the
metal polish come into contact with the paintwork, as metal polished, steel wool, solvent and vitreous enamel
cleaners will harm the paintwork.
The flame effect of the fire may deposit some soot onto the coals, whilst light powdery deposits are acceptable,
large deposits will need to be removed, along with any debris, which may have collected. This can be done
using a soft brush. Remove the coals for cleaning. Dust down using soft brush. Check the burner and
remove any deposits, which may have collected, again by using a soft brush.
It is advised that a vacuum cleaner should not be used
.
REMOVING AND REPLACING COALS
Ensure that the fire and pilot are turned OFF and that the fire is cold.
In time due to expansion and contraction, the "coals" may settle. It is suggested that the coals unless
satisfactory be re-arranged. The settlement of the coals may cause minor abrasions and expose some white
spots. These spots usually add realism to the fire when in operation.
If coals are to be replaced or re-arranged then remove the existing coals and replace as described in
Installation Instructions (pages 12-14).
Note: - coals can be rotated about their positions as an aid to balancing the flame picture. This should only be
done by using a pair of long handled tongues.
Ensure that NO coals are in such a position that they could become unstable and fall off the fire bed.
It is important to use only that number of coals stated in these instructions.
Hands should be washed after handling coals. -
