PLEASE NOTE
1. The Wonderfire Airflame Excel is to be used only with the type of gas for which it
was supplied. Never attempt to use the appliance with other gas types.
2. Always use a fireguard complying with BS6539 or BS6778 for the protection of the
young, elderly, or infirm.
3. The fire is lit by a Piezo electronic spark unit. Batteries and electrical supply are
not required.
4. An odour may be noticeable when your fire is first lit. This is due to the newness of
certain materials used in the manufacture and will disappear after a few hours of
use.
5. Never throw paper, ash, or any other materials onto your fire.
6. The chimney should have been thoroughly swept prior to installation.
7. The chimney should be checked annually to ensure continued clearance of
combustion products, and that no soot or debris has built up behind the appliance.
8. Your fire should be checked annually by a competent person according to the
maintenance requirements in the installation manual and in accordance with the
Gas Safety (Installation and Use) Regulations 1994 (as amended) or the rules in
force.
9. Ensure that any purpose made room ventilation is kept free from obstruction.
10. This appliance is fitted with an A.S.D. (Atmospere sensing device). If the appliance
shuts down after a period of operation for no apparent reason, then stop using the
appliance until the installation and the appliance have been thoroughly checked by
a competent person.
11. Installation must be in accordance with the installation instruction and the rules in
force.
12. If the fire goes out for any reason, wait at least three minutes before attempting to
re-light.
The Hearth
NOTE: Hearth requirements in Figure
1. The appliance must be mounted
behind a non-combustible hearth
(N.B. conglomerate marble hearths
are considered as non-combustible).
The appliance can be fitted to a
purpose made proprietary class “O”-
150°C surround. The hearth material
must be at least 12mm thick. The
periphery of the hearth (or fender)
should be at least
50mm above floor level to discourage
the placing of carpets or rugs over it.
The surface of the hearth must be sufficiently flat to enable the bottom of the front
surround and the bottom front cover to be aligned horizontally. Any excessive
unevenness (uneven tiles, Cotswold stone, etc.) should be rectified.
The appliance must not stand on combustible materials or carpets.
Shelf Clearances
The minimum height from the top surface of the hearth to the underside of any shelf
made from wood or other combustible materials is as follows:-
• For a shelf up to 150mm deep : Minimum height = 818mm.
• For a shelf deeper than 150mm : 818mm + 12.5mm for every 25mm depth over
150mm.

Ventilation requirements
Note: see convector instructions if being installed within a Wonderfire convector box for
ventilation requirements.
For all Airflame Excel Mk.3 models except AF16NV / AF16NVP:
GB only: A permanent ventilation grille of fixed design and having a minimum free area of
100cm2must be fitted with direct access to outside air to room.
IE only: This appliance must be installed in accordance with ICP 3.
For AF16NV/AF16NVP
GB only: Purpose provided ventilation is not normally required for these models, however on
larger fireplace openings with a height of over 24" and a width of over 18" we do recommend
that a purpose ventilation grille of 100 cm2 is fitted. In all cases a clearance of combustion
products test (spillage test) must be carried out.
I.E. only: This appliance must be installed in accordance with ICP 3.
Please note: This appliance is not
supplied with a decorative
firefront. A slotted firefront with a
minimum free area as shown in
figure 2 must always be used.
OPERATION OF THE FIRE
This fire is controlled by a four
position gas tap mounted in the
front of the appliance. In addition
to the OFF setting there is a pilot
position and two heat control
settings.
To Light the Pilot
Ensure that the control knob is turned to the OFF position. Depress the control knob
and turn anticlockwise until the IGNITION position is reached, continue turning the
knob to activate the piezo ignition. Two ‘clicks’ will be observed, and the pilot should
ignite. Hold the knob in this position (keeping it depressed) for ten seconds to allow
the flame supervision device to establish.
Observe if it alight by looking through the slots to the left hand end of the front coals.
If the pilot does not light immediately, repeat the above procedure, keeping the knob
depressed for several seconds in order to purge any air from the system.
If after ten seconds, ignition has not occurred, turn the control knob back to the OFF
position and repeat the ignition procedure after 3 minutes.
Once the pilot is lit, keep the control knob depressed for ten seconds to allow the
flame supervision device to establish.
When the control knob is released, the pilot should remain lit. If the pilot fails to
remain lit, repeat the ignition procedure, this time keeping the control knob depressed
for a longer period of time.

Lighting the Main Burner
Once the pilot light is established the main burner can be lit by turning the control
knob anticlockwise to the HIGH position.
Controlling the heat setting.
In order to change from one setting to another depress the control knob slightly and
turn the knob to the required position. Alternatively, if a setting between LOW and
HIGH is required, then the control knob may be turned to this position.
Note: We recommend you use the appliance at a low setting for the first few hours of
use to reduce the thermal cracking of the surface of the burner.
Surface cracking of the burner is normal and is no cause for concern. Whist binding
materials are being burnt out of the burner there may be a slight odour.
To Turn the Fire back to Pilot Setting
Depress control knob and turn clockwise until pilot setting is reached.
To Turn the Fire OFF Ensure control knob is in pilot position, depress control knob
and turn clockwise to the OFF position.
For fires fitted with Aeration control
For appliances fitted with variable aeration control, the lighting and adjustment
procedures are as normal. To operate the aeration control system, the following
procedure should be followed:
•Allow the appliance to warm up, (for at least fifteen minutes) in the fully aerated
position, with the control lever pushed in to the locked position – see figure 1.
•Switch to the minimum aerated position by slightly lifting the control lever. A
spring mechanism will close the aeration shutter.
•To return to the fully aerated position push the control lever in and slightly
downwards until it rests in its locked position.
Please note : It is advisable to run the fire in its fully aerated mode (control knob
pushed in) at the beginning of each operation and if running at the minimum rate
setting, or to burn off any carbon deposits which may have built up after prolonged
use of the minimum aerated setting.

CLEANING
Note: Before attempting any of the following ensure that the fire has been allowed to
cool completely.
Note: Some discoloration of the coals is normal.
The cast parts of the fire should be carefully cleaned with a lint free damp cloth. On
no account should any metal polish or similar be used as this may prove harmful to
the surface.
The coals should normally require no maintenance between the annual inspection
described in the installation and maintenance instructions. However, if your fire is
used frequently the coals may need cleaning. The coals should be removed and any
sooting carefully removed from the surface with a soft brush.
The burner surface can be carefully vacuumed to remove any loose particles. Note:
Surface cracking is normal and no cause for concern.
To reassemble, take the following steps.
PLACING THE COALS
Placing the front coal
Position in front of the burner as shown in figure 2. The front coal should fit snugly
between the burner and the two raised tabs on the front edge of the tray.
Figure 2

Placing the fuel matrix
Position on top of the burner as shown in
figure 3. The rear face of the burner
should locate into two cut-outs on the top
face of the rear legs. Ensure that the
matrix sits flatly on the top of the burner.
Placing the dress coals
These consist of:
•2 x Finger coals
•4 x Square
•15 x Random cut coals
Begin the coal build by placing a square
coal in the centre of the front coal,
ensuring that it bridges across to the
matrix as shown in figure 4.
Next, take four random coals and place
along the front coal as shown in figure 5.
Again, ensure that these coals bridge
across from the front coal to the matrix.
In order to get the best flame effect, it is
important that the coals are evenly
spaced, and sit 10-15mm from each other. Figure 4

Placing the dress coals – continued
Next, take both finger coals and
place one at each end of the front
row of coals as shown in figure 6,
again making sure that they bridge
across from the front coal to the
matrix.
Now take six more of the random
shaped coals and position as shown
in figure 7. This second row of coals
should rest on top of the first row,
overlapping by 5-10mm. Again,
ensure even spacing to obtain the
best flame effect.
NG MODELS ONLY: Next, take five
random shaped coals and arrange as
shown in figure 9. Again, these coals
should overlap the previous row by
5-10mm. Once again ensure even
spacing.
LPG MODELS ONLY: Take three
random coals and position in the
centre of the matrix, spaced 10-
15mm from each other to make the
third row. Discard the two
remaining random coals.

Finally, take the three remaining
square coals and position at the
back of the matrix as shown in figure

the previous row by 5-10mm and
also, even spacing is once again
important.
