Preparation
Before installation
Ensure that the local distribution conditions (identification of the type of gas and pressure) and
the adjustment of the appliance are compatible. Refer to burner data badge plate.
Inspect the chimney
Ensure that:
•It only serves one fireplace
•Any terminal or cowl fitted is approved for use with this type of appliance.
•It is clear of any obstruction and any damper or restrictor is removed or fixed
permanently in the fully open position.
•Any chimney used for an appliance burning a fuel other than gas must be thoroughly
swept before installing any gas appliances.
•With an L.P.G. (propane) fire, any air supply entering the fireplace below floor level is
completely sealed off.
•The chimney is properly sealed so that the combustion products do not come into
contact with combustible materials outside the chimney.
•The base of the chimney is clear of loose debris, bricking up, etc.
Check with a smoke match that there is a positive updraught present. If a terminal is fitted check
that it is free from obstruction and does not restrict the exit and safe dispersal of combustion
products.
Location
This appliance is not suitable for installation in a room containing a bath or shower. The Theme
22 may be installed to a masonry chimney with a minimum cross sectional area of 24,000
sq.mm, lined flue with a minimum dimension of 100mm or a minimum diameter of 175mm and a
minimum effective height of 3m. A builder's opening with sufficient volume for debris collection
conforming to Fig. 2 must be provided.
The installation is fully described in the next section.
The appliance must only be installed into an opening against a non-combustible wall.
Clearances
If a shelf is to be fitted above the fire, perhaps as part of a surround, it must be positioned a
minimum of 1m (39in.) above the top of the hearth, and project no more than 200mm (8in.) from
the front plane of the opening. Combustible material such as wood may be fitted to within
100mm (4in.) of either side of the opening so long as it projects no more than 100mm (4in.) from
the front plane of the opening. Soft furnishings, decorations and some wall coverings may
discolour or scorch if positioned too close to the fire
Installing the fire

Placing the coals
Refer to Figs. 8
1. Place 7 large coals on the rear shelf to make row 1.
2. Place 7 large coals across the front of the fire to form row 4.
3. Place the remaining 5 large coals above and behind row 4 to make row 3.
4. Take the 2 small coals and place one at each end of row 3.
Leak test & pressure test
1. Turn on the main gas supply and check for gas soundness.
2. Remove pressure test screw, and fit pressure gauge to pressure test point.
3. Light the fire (see next section).
4. Turn control knob anti-clockwise to High position.
5. When the control knob is in the High position, you should have a gas pressure of
18.0mbar ± 1.0mbar when using natural gas and 36.0mbar for propane.
6. Extinguish the fire by turning the control knob clockwise to the Off position.
7. Remove the pressure gauge and replace the pressure test screw. Check again for gas
soundness.
8. Fit the front fret by hooking the support lugs at each end over the slotted front plate on
the burner (if using a Straxgas fret), or place an alternative front fret in front of the
burner.
Note: If a fret from another manufacturer is being used, it must comply with the minimum free
area requirements of Fig. 1.
Lighting the fire
The appliance Data Badge is positioned in front of the burner behind the fret and carries the
control knob positions (Fig. 9 or 10 depending on gas type). The full lighting procedure is as
follows:
1. Push control knob in as far as possible on gas control.
2. Turn knob anti-clockwise until a click is heard. The knob will stop at the ignition position
and a spark should be seen at the tip of the ignition probe. At the same time the pilot
flame should light. KEEP THE KNOB PRESSED IN FOR 10 SECONDS. If the pilot
should fail to light, turn the control knob clockwise to the 'off' position, wait 3 minutes
and repeat the procedure.
3. When the pilot flame is alight the control knob should be allowed to spring out slightly.
Turn the knob fully anti-clockwise to the high position. The pilot flame should then ignite
the main fire.

4. The height of the flames can be adjusted by turning the control knob between the low
and high positions. Note that the knob 'latches'
in position at either end of this movement and
must be pushed in slightly before it can be
turned.
5. The appearance of the flames can be altered by
means of the air adjustment lever positioned to
the right of the control knob (natural gas version
only). Moving the lever up will admit more air
and produce a 'coke fire' effect. Moving it down
will close off some of the air and simulate a
'coal fire' with flickering flames.
6. To turn the fire off, depress the knob slightly
and turn it to the pilot position.
7. To completely extinguish the fire depress the
knob slightly and turn to the 'Off' position.
Check for clearance of
products of combustion
1. Light the fire.
2. Close all windows and
doors.
3. After approximately 5
minutes place a shrouded
smoke match 70mm from
the right hand side, inside
edge of the trim, 10mm
below and 10mm within
the opening of the fire as
shown in Fig. 11, 11a &
11b. Ensure that the
smoke is drawn into the
fire aperture. If spillage is
detected, operate the fire
for a further 10 minutes
and repeat the test. If
spillage is still detected the cause must be discovered and the fault corrected. If the fault
cannot be corrected, disconnect the gas supply to the appliance and seek expert
advice. Possible causes of spillage are chimney restrictions, or an incorrect cowl or
terminal.
4. If there is an extraction fan in a nearby room then the spillage test must be repeated
with the fan turned on and any interconnecting doors between the fire and the fan
location left open.
Instruct the user
1. Hand over these Installation Instructions and the User Instructions to the person who is
going to use the fire and explain how to light and operate the appliance. Explain how the
fire may be lit, if necessary, by means of a long spill or taper.
2. Make certain that the user is aware that the ceramic blocks and coals must be located
in accordance with the instructions, and that the appliance should be serviced at regular
intervals by a competent person to ensure continued safe operation.
3. Explain that this appliance is fitted with an oxygen depletion sensor incorporated into
the pilot body. Should the fire repeatedly extinguish itself, the cause should be sought
and remedied as this may indicate spillage into the room of combustion products.
4. Indicate the tie-on warning label, which the customer must remove and read.
5. Advise the user that any smell given off by the appliance will clear away after a little
use.
6. Point out that these instructions must be retained in a safe place for future use.
