2 Important Notes
This stove is a fuel effect radiant convector. Before installation
ensure that the local distribution conditions (identification of the
type of gas and pressure) and the adjustment of the appliance are
compatible.
The data label is located behind the controls cover.
The installation must be in accordance with these
Instructions and National Regulations and must
be carried out by a qualified installer.
Any flue damper plate or flue restrictor must be
removed or fixed permanently in the fully open
position, or shall only be fitted in accordance with

National Regulations.
If the chimney has previously been used to burn
solid fuel, the chimney should be swept before the
stove is installed.
Before the stove is installed a flue test in accordance
with National Regulations should be carried out.
The gas connection must be in accordance with
National Regulations.
The stove is fitted with a spillage combustion monitoring safety
device (O.D.S). This system is not
adjustable, and must not be put out of action.
If any parts of the spillage monitoring system
require replacement only original manufacturers
parts must be used.
All surfaces except the control cover plate and the controls
themselves are considered to be working surfaces.
When operating on Natural Gas the stove is intended for use on a
gas installation with a governed meter.

4. Installation
Install the stove in accordance with the
requirements given below. If a concealed gas
connection is to be made prepare the pipework
prior to installing the stove.
(i) SITING THE STOVE
The stove can be installed in any adequate area
suitable for solid fuel fires and stoves.
Clearances from non-combustible material in the
fireplace opening must be at least 50mm on the
left side, 50mm on the right hand side and
50mm at the back. These distances must be
extended to a minimum clearance of 500mm
from any combustible material.
(ii)Hearth
The stove must stand on a fireproof hearth made
of non-combustible material of minimum
thickness 12mm and be of sufficient size to
accommodate the stove. (See Fig 1).
(iii)Fire Surround & Shelves
It is recommended that a fire surround should not
be closer than 500mm from the stove, if
manufactured from a combustible material.
A combustible shelf may be fitted provided that it
is not more than 150mm deep and there is at least
500mm clearance from the top of the stove. Curtains and other soft
furnishing must be at least 500mm away from the top of the stove.

(iv) FLUE CONNECTION
The flue should be at least 3m high and at least
125mm diameter or equivalent area.
Horizontal or negative gradients in the flue pipe
should be avoided.
It is recommended that a minimum height of
500mm from the stove should be established
before any significant change in the direction of
the flue.
(v) VENTILATION
Ventilation should be in accordance with National
Regulations. In the United Kingdom purpose
provided ventilation is not normally required, except in new build
houses.
(vi) GAS CONNECTION
The gas supply connection is behind the controls cover plate, left
hand side of the gas valve.
A nut and olive (strapped to the valve body), is supplied with the
stove.
The gas supply should incorporate a service tap,
be purged and any loose matter removed.
Connect the gas supply pipe and check for gas
soundness.

5 positioning of the logs
Slacken the Allen screw using an Allen key securing the stove
door and open the door (as shown below)

Close the stove door and secure with an Allen key. Under no
circumstances should the stove be operated with the door open,
without the door attached or the glass damaged.

6 Commissioning the stove
When lighting the pilot follow these instructions exactly.
Lighting instructions
Should the stove be extinguished for any reason
wait 3 minutes before re-ignition is attempted. Slacken the rear
pressure test sealing screw on the left hand side of the gas valve
(fig 6) and connect a suitable pressure gauge to the pressure
test point.
(i) Lighting The Pilot
Turn knob A (fig 6) counter clockwise towards the ignition
position (IGN) until reaching stop, press down and hold for five
seconds (only pilot gas flows).
Continue pressing down knob A while turning further counter
clockwise to activate piezo, continue to hold down for ten seconds
after pilot burner has been lit. If pilot does not light, steps 1 and 2
can be repeated immediately. Upon lighting, release knob and turn
further counter clockwise to ON position. Pilot gas flows and main
gas flows in accordance to the temperature setting of knob B.
(ii)High Setting
If the pilot is not already lit, light the pilot as described in (i)
Turn knob B anti clockwise until the high setting is reached.
Check the setting pressure is in accordance with that given in the
technical information setting adjust if necessary. (fig 6)
(iii) Low setting
Turn knob B clockwise to low setting (just before flame is
extinguished). Check that the setting pressure is in accordance with
that given in the technical section.

Adjusting the flame Height (fig 6)
To turn the stove on and/or to increase the flame
height, press the ▲ button and the small button A at the same time
on the remote handset. Continue pressing until the desired
flame height is obtained. Press and hold the ▼
button to reverse the procedure.
The receiver is equipped with a built-in delay,
recognisable by the flickering light, to facilitate
fine adjustment of the flame. The motorised valve
is equipped with a slip clutch, allowing manual
adjustment of main gas by turning knob B.
To Turn Off Gas to Stove
Turn knob A clockwise until reaching stop. In
this position only pilot gas flows. To shut off the
valve completely, press down slightly and
continue to turn clockwise from pilot position to
the OFF position. The safety interlock prevents
re-ignition of the pilot flame until the
thermocouple has cooled down sufficiently
(elapsed time will vary based on thermocouple
type). Switching off the remote is not necessary.
Disconnect the pressure gauge, tighten the test point sealing screw
and test for gas soundness.
Handset Information
Note : Mains electrical power is not required as this system runs
on batteries only. (Alkaline recommended)
Handset 1 x 9V block
Receiver 4 x 1.5v AA

Figure 6 Control Valve and transmitter
Note
It is recommended to turn the combination control either to the off
or pilot position if the appliance is left unattended for long periods
(eg away on holiday), so that it cannot receive commands from the
remote transmitter. Exercise caution when leaving the appliance
unattended, in exceptional cases sound waves from sources other
than that of the transmitter can cause flame height adjustment. For
the handset to function correctly, the transmitter must remain
within the range of the receiver. The transmitter should not be used
in very close proximity of the receiver (less than 1 metre/3 ft) as
this could, in very rare cases produce an electronic switching error.
This could block the motor when the knob reaches the end.
7 Check for spillage
Close all doors and windows in the room containing the appliance.
Light the stove and turn the control knob to ‘HIGH’. Leave the
appliance for 5 minutes.
Apply a smoke match along the bottom edge of the draught
diverter. The installation is satisfactory if the smoke is drawn into
the stove.

If in doubt wait a further 10 minutes and then repeat the test.
If there is a fan in a nearby room the spillage test should be
repeated with the fan running and all connecting doors between the
stove and the fan left open.
If in doubt disconnect the appliance and seek expert advice.
8 Customer Briefing
Hand these Instructions and the Users Instructions
to the customer.
Advise the customer how to use the stove. Point
out that the Operating Procedure is in the Users
Instructions.
Explain to the customer that the stove has a flame
failure and spillage monitoring system. Point out
the explanation of this system is in the Users
Instructions.
Advise that if the monitoring system repeatedly
shuts off the stove, it should be switched off and a
specialist consulted.
Advise that if the stove goes out for any reason,
wait at least three minutes before re-lighting.
Advise the customer that due to the newness of
materials the stove may give off a slight smell for
a period of time after commissioning. This is
quite normal and any odours should disperse after
a few hours operation.
Stress that no extra coals or logs must be added
over and above those supplied with the appliance
and that any replacements must only be
authorised Firebelly spares.
Recommend that the stove is regularly serviced
and the flue system checked by qualified persons.
