INSTALLATION REQUIREMENTS

1.1 CONDITIONS OF INSTALLATION

In Great Britain :-

It is the law that all gas appliances are installed only by a CORGI Registered
Installer, in accordance with these installation instructions and the Gas Safety
(Installation and Use) Regulations 1998 as amended. Failure to install appliances
correctly could lead to prosecution. It is in your own interest and that of safety to
comply with the law.

The installation must also be in accordance with all relevant parts of the Local and
National Building Regulations where appropriate, the Building Regulations
(Scotland Consolidation) issued by the Scottish Development Department, and all
applicable requirements of the following British Standard Code of Practice.

1. B.S. 5871 Part 3 Installation of Decorative Fuel Effect Gas Fires

2. B.S. 6891 Installation of Gas Pipework

3. B.S. 5440 Parts 1 & 2 Installation of Flues and Ventilation

4. B.S. 1251 Open fire place components

5. B.S. 715 Metal flue pipes for gas appliances

6. B.S. 6461 Part 1 Installation of Chimneys and flues

7. B.S. 1289 Clay Flue Blocks and Terminals

8. I.S. 813 : 1996 Domestic Gas Installation (Republic of Ireland)

In Republic of Ireland :-

No purpose made additional ventilation is normally required for this appli­ance, when installed in G.B. When Installing in I.E. please consult document
I.S. 813 : 1996 Domestic Gas Installation, which is issued by the National
Standards Authority of Ireland. If installing in Northern Ireland, please
consult local building regulations. Any purpose made ventilation must be
checked periodically to ensure that it is free from obstruction.

1.2 FLUE AND CHIMNEY SUITABILITY

This appliance is designed for use with conventional brick built or lined chimneys
and fabricated flues. It is also suitable for use with pre-cast flue blocks conforming
to B.S. 1289 and metal flue boxes conforming to BS 715. All flues must conform
to the following minimum dimensions.

Minimum diameter of circular flues 125 mm (Without Flue

Restrictor Fitted)
Minimum effective height of all flue types 3 metres
When fitting to conventional chimneys or 175mm flues it may be desirable to
fit the flue restrictor baffle (supplied) to reduce the flue flow and increase the
efficiency of the fire. Safe clearance of products must always be checked by
carrying out a smoke match test as described.

4

1.3 FIREPLACE / SURROUND SUITABILITY

The fire must only be installed on a hearth it must not be installed directly onto
carpet or other combustible floor materials.

The fire is suitable for fitting to non-combustible fire place surrounds and propri-

etary fire place surrounds with a temperature rating of at least 150oc.

If a heating appliance is fitted directly against a wall without the use of a fire
surround or fire place all combustible material must be removed from behind
the trim. Soft wall coverings such as blown vinyl, wall paper etc. could be
affected by the rising hot air and scorching and/or discoloration may result.
Due consideration should be made to this when installing or decorating.

1.4 SHELF POSITION

The fire may be fitted below a combustible shelf providing there is a minimum dis­tance of 200mm above the top of the fire and the shelf does not project more than
150mm. If the shelf overhangs more than 150mm the distance between the fire
and the shelf must be increased by 15mm for every 25mm of additional overhang
over 150mm.

1.5 FLUE / CHIMNEY INSPECTION

Before commencing installation, a flue or chimney should be inspected to ensure
that all the following conditions are satisfied.

1. Check that the chimney / flue only serves one fire place and is clear of any

obstruction. Any dampers or register plates must be removed or locked in
the open position.

2. Brick/stone built chimneys or any chimney or flue which has been used for

an appliance burning fuel other than gas must be thoroughly swept. The
base of the chimney / flue must also be thoroughly cleared of debris etc.

3. Any under-floor air supply to the fire place must be completely sealed off.

4. Ensure that the inside of the chimney / flue is in good condition along it’s

length and check that there is no leakage of smoke through the structure
of the chimney during and after the smoke pellet test. With pre-cast flues

it is especially important to check the inside of the flue for extruded
cement / sealant protruding from the joints between the flue
blocks. If present, these should be removed by rodding the flue
before proceeding with the installation.

5. Using a smoke pellet, check that there is an up-draught in the chim

ney / flue and that the smoke can be seen issuing from the terminal /
chimney pot outside.

5

There must be no leakage of smoke through the structure of
the chimney during or after the smoke pellet test and it is
important to check inside upstairs rooms adjacent to the chimney /
flue. Check the chimney pot / terminal and general condition of the

brickwork or masonry. If the chimney or flue is in poor condition or if
there is no up-draught do not proceed with the installation. If there is a
history of down-draught conditions with the chimney / flue, a tested and
certificated flue terminal or cowl suitable for the relevant flue type should
be considered.

6. A spillage test must always be carried out during commissioning of

the appliance.

1.6 FIRE PLACE OPENING AND CHIMNEY CATCHMENT SPACE

The front opening of the fire place must be between 330 and 430 mm wide, and
between 550 and 565mm high. If the opening exceeds these dimensions then a
surround must be constructed from suitable non-combustible material to produce a
correct size opening. Any surround must be suitably sealed to the fire place to
prevent leakage. See below in fig.1

When installing into a brick built chimney, you must ensure that there is sufficient
depth to accomodate any debris which may fall from the chimney. This depth
must be sufficient to accomodate 12 litres of volumetric space.

1.7 FITTING TO FIREPLACES WITH EXISTING CHAIRBRICKS AND
CONVENTIONAL BRICKBUILT CHIMNEYS

This appliance is suitable for use in fireplaces fitted with an existing chairbrick
without the need for removal of the chairbrick, providing the minimum depth of the
fireplace exceeds 190mm. If the depth is less than 190mm then the spacer
(optional) must be used to give a minimum clearance from the rear of the fire to
the rear of the chairbrick of at least 90mm to allow sufficient space for the collec­tion of debris which may fall down the chimney. The fireplace must be checked to
ensure that no part of the chairbrick is within 50mm of the flue outlet of the fire
when installed.

1.8 FITTING TO PRE-CAST FLUE INSTALLATIONS

When installing this appliance into pre-cast flues, always ensure that the
spigot restrictor baffle has been removed.

To install the fire box in to pre-cast flue starter blocks, there must be at least
120mm from the mounting face of the fire to the rear of the pre-cast flue
starter block to allow sufficient space for debris collection. It is important to

consider this depth when choosing a fire surround as the thickness of the fire
surround must be sufficient to give a total depth of at least 120 mm to the rear of
the starter block, otherwise there will be insufficient depth. To increase this depth
the fire surround may be packed away from the wall using suitable
non-combustible board, providing the installation is correctly sealed. If in doubt
about the suitability of the fire contact CFM Europe for advice before proceeding.
It is important to ensure that the pre-cast flue is in good condition and is free from
extruded mortar or sealant from between the flue blocks.

This appliance has been tested for use in a pre-cast flue block complying
with BS 1289. In accordance with BS 1289 Part 1, pre-cast flues built with
directly plastered faces (front or rear) are not correctly installed as to ensure
proper operation with any type of gas fire. In some instances of this flue
construction, temperature cracking of surface plaster may occur through no
fault of the appliance. An air gap or some form of insulation material should
be installed to prevent normal flue temperatures from damaging wall
surfaces.

1.9 FITTING TO PRE-FABRICATED TWIN WALL METAL FLUE BOXES

The appliance may be fitted to twin wall metal flue boxes conforming to the con­structional requirements of BS 715, (for example the Selkirk LFE 125 box). The
box must have a minimum flue diameter of 125mm internal and minimum internal
dimensions of 160mm deep by 580mm high by 350mm wide. There are no maxi­mum dimensional requirements for the box. The top face of the box must be
insulated with a minimum thickness of 50mm of non-combustible mineral wool
insulation or similar material. The flue box must stand on a non-combustible base
of minimum thickness 12mm.

8

1.10 HEARTHS

This appliance must only be installed on to a concrete or non-combustible hearth.
The hearth material must be a minimum thickness of 13mm with the top surface at
least 50mm above the floor. The hearth must be fitted symmetrically about the fire
opening and have a minimum width of 760mm and a minimum projection of
300mm forwards from the fire opening.

1.11 SPILLAGE MONITORING SYSTEM

This appliance is fitted with an atmosphere sensing spillage monitoring system in
the form of an oxygen sensing pilot. This is designed to shut the fire off in the
event of a partial or complete blockage of the flue causing a build up of combus­tion products in the room in which the fire is operated. The following are impor-
tant warnings relating to this spillage monitoring system :-

1) The spillage monitoring system must not be adjusted by the installer.

2) The spillage monitoring system must not be put out of operation.

3) When the spillage monitoring system is exchanged only a complete original
manufacturers part may be fitted. It is not possible to replace individual parts on
the pilot system on this appliance, only a complete pilot assembly (including the
thermocouple) may be fitted.

2.2 INSTALLING THE FIRE BOX

Establish which type of flue you are intending to install the fire in to :-

225 x 225mm (9 inch x 9 inch) brick built chimneys
175mm (7 inch) diameter lined brick or stone flue, or insulated pre-fabricated
metal flue box to B.S. 715.

When installing into 125mm (5 inch) diameter lined brick or stone flue, or
insulated pre-fabricated metal flue box to B.S. 715 and pre-cast flues the
restrictor baffle must not be fitted.

A spillage test must always be carried out to check satisfactory
clearance of flue products, regardless of the type of flue the
appliance is being fitted to.

10

a) Remove the trim (Ora / Aluma models only). Remove the burner heat

shield from the front of the fire box to allow access to the burner. See

fig. 3 below.

Fig. 3

b) Ensure that the hearth is protected from damage and carefully lift the

fire box into the fire opening, then slide it back into position. Check that

the fire box flange fits flush to the sealing face of the fire surround or

wall with no gaps present.

c) Remove the four retaining screws securing the burner to the firebox.

The base of the burner unit can now be pulled forward, allowing the

burner to be removed from the fire box. See fig. 4 below.

Fig. 4

11

Continue for all models

Whilst the fire box is still in position, decide which side the gas supply is to enter
the fire from. If concealed pipe work is required plan the pipe run to enter the fire
box through one of the openings in the sides of the fire box below the fuelbed sup­port panel and connect to the isolating / inlet elbow. The gas connection to the
appliance should be made to the isolating / inlet elbow using 8mm rigid tubing.
There must be no soldered joints within the firebox. See fig. 5 & 6 below for
suggested concealed pipe layouts.

Fig. 5

Fig. 6

Note : Before breaking into the gas supply a pressure drop test should be
carried out to establish that the existing pipework is sound.

Carefully withdraw the fire box from the opening to enable the gas supply and fire
fixing to be completed.
There is a choice of methods of fixing the firebox which are provided to enable the
installer to deal with any type of installation.

The preferred method of fixing which is suitable for almost all situations is
the cable fixing method which is described in the following section in detail.

To fit using the preferred cable method proceed as follows-

e) Mark out and drill 4 off No 14 (6mm) holes in the back face of the fire

opening in the positions shown below in fig. 7

Fig. 7

Fit the wallplugs provided and screw the fixing eyes securely into the rear of the
fire opening. If the clearance at the rear of the fire is at the minimum specified for
a precast flue application, it may be necessary to bend over the lower fixing eyes
after screwing them fully in to the rear of a pre-cast starter block.

f) Uncoil the two fire fixing cables and thread one end of each of the

cables through one of the two holes on each side of the flue outlet

shroud.

g) Position the fire carefully on the (protected) surface of the hearth and

reach into the fire opening. Thread each of the cables vertically

downwards through the pair of fixing eyes on the same side of the fire.

Thread the free end of the cables through the corresponding circular

hole on each side of the lower rear of the fire. Carefully slide the fire

box back into the fire opening and pull both cables tight.

h) Thread a tensioning screw over each of the cables and ensure that the

tensioning nut is screwed fully up against the hexagon shoulder of the

tensioning screw (this provides maximum travel for the tensioning nut).

i) Fit a screwed nipple on to each of the cables and pull hand tight up

against the tensioning screw, then secure each nipple with a flat

bladed screwdriver. See fig. 8 overpage

j) Evenly tighten the tensioning nuts to tension both cables and pull the

fire snugly against the wall. Do not overtighten, it is only necessary to

pull the seal up against the sealing face of the wall, it does not need to

be compressed. Check that there are no gaps behind the seal.

k) With the fire securely in place, if a concealed gas connection has been

made through either of the access holes in the sides of the fire, the

holes should be closed around the pipe to prevent leakage of air

through the gap around the pipe.

l) Refit the burner. Fit the four retaining screws and check that the burner

is correctly locked into position.

14

m) Refit the front burner heat shield to the sides of the fire box (2 Screws)

n) Before making the final gas connection, thoroughly purge the gas

supply pipework to remove all foreign matter, otherwise serious

damage may be caused to the gas control valve on the fire.

The other firebox fixing method is as follows :-

In installations where the cable method is not suitable (e.g. loose masonary in rear
of fire opening) the firebox can be secured to the fire surround using four screws
and wall plugs provided. Below (fig.9) is a diagram to indicate the hole centre
positions available on the firebox to facilitate the screw fixing to the fireplace /
surround.

2.3 GAS SOUNDNESS AND INLET PRESSURE

a) Remove the pressure test point screw from the inlet elbow pressure test

point and fit a manometer.

b) Turn on the main gas supply and carry out a gas soundness test.

c) Depress the control lever to the position marked pilot. Hold down the

control lever for a few seconds to purge the pipe work. The burner

should light, continue to hold the control lever for a few seconds to latch

the slide valve then lift to the full-on position.

d) Check that the gas pressure is 20.0 mbar (+/- 1.0mbar) 8.0 in w.g.(+/-

0.4 in w.g.) for FSRN**G & FSTN**G models

e) Turn off the fire, remove the manometer and refit the pressure test point

screw. Check the pressure test point screw for gas soundness with the

appliance turned on using a suitable leak detection fluid or detector.

16

3.1 ASSEMBLING THE CERAMICS AND FUEL BED

a) Place the insulation mat centrally on to the fuelbed support then place

the ribbed hard ceramic fuelbed base on top of the mat and pull both

fully forwards to the burner. Make sure that the fuelbed base is

located centrally in the fire box. Ensure that both the mat and

fuelbed base fit fully down onto the fuel bed support and are not

lodged on the burner. See fig. 10 below.
Fig. 10

b) Position upper fuelbed component on to the locating pegs on the top of

the fuelbed base, ensuring that it is correctly seated as shown below in

fig. 11

Fig. 11

17

c) Fit the two parts of the ceramic front coal support on to the front support

bracket, ensuring they are correctly located over the locating tabs, as

shown below in fig. 12

Fig. 12

d) Select seven of the coals and arrange along the front ceramic coal

support using the shallow depressions as guidance for the

coal position. See fig. 13 below

Fig. 13

18

e) Select the four coals and arrange along the front of the fuelbed, direct

ly behind the front row of coals. Leave gaps between the

coals in line with the front flame notches on the front of the fuelbed

(shown below arrowed), this enhances the front flames and provides the

most pleasing flame effect. Select the two smallest coals and place

them at each end of the second row of coals. See fig. 14 below.

Fig. 14

f) Select five of the coals and arrange along the fuelbed behind the

second row of coals spacing them evenly and positioning them as

shown below in fig. 15

Fig. 15

19

g) Select the remaining four coals and position to fill the gaps left at the

top rear of the fuelbed. The coals will locate naturally into the

depressions in the top rear of the fuelbed, see fig 16 below

Fig. 16

The exact position and fit of the coals may be finely adjusted to give the most
pleasing and random appearance.

Warning : Use only the coals supplied with the fire. When replacing the

coals remove the old coals and discard them. Fit a complete set of

coals of the correct type. Do not fit additional coals or any coals

other than a genuine replacement set.

This appliance uses fuel effect pieces containing Refractory Ceramic Fibres
(R.C.F.), which are man-made vitreous silicate fibres. Excessive exposure to
these materials may cause temporary irritation to eyes, skin and respiratory
tract. Consequently, it makes sense to take care when handling these
articles to ensure that the release of dust is kept to a minimum. To ensure
that the release of fibres from these R.C.F. articles is kept to a minimum,
during installation & servicing we recommend that you use a HEPA filtered
vacuum to remove any dust and soot accumulated in and around the fire,
before and after working on the fire. When replacing these articles we
recommend that the replaced items are not broken up, but are sealed within
a heavy duty polythene bag, clearly labelled as “RCF waste”. This is not
classified as “hazardous waste” and may be disposed of at a tipping site
licensed for the disposal of industrial waste. Protective clothing is not
required when handling these arrticles, but we do recommend you follow the
normal hygiene rules of not smoking, eating or drinking in the work area,
and always wash your hands before eating or drinking.

This appliance does not contain any component manufactured from
asbestos or asbestos related products.

20

3.2 FITTING THE TRIM (ORA / ALUMA MODELS)

a) Refitting the trim is achieved by locating the rear flange of the trim over

the flange on the firebox mounting face, then replacing the screws at

the L/H and R/H bottom of the trim.

3.3 FITTING THE TRIM (TOCCATA MODELS)

a) Fit the two side pieces of the trim by overlapping the lips of the trim

over the side lip of the firebox.

b) Fit the top piece of the trim by overlapping the lips of the trim over the

lip of the firebox and over the two side trims.

3.4 TO FIT THE FENDER (ALL MODELS)

a) Attach L/H & R/H Brackets to fender with M6 pozi screws which locate

onto the burner retaining brackets at each end of the burner assembly.
See fig. 17, 18 & 19.

3.5 LIGHTING THE APPLIANCE

a) Turn on the gas isolation tap.

b) Depress the control knob and turn anti-clockwise to the position

marked pilot. Hold in the control knob for a few seconds to purge the

pipe work.

c) Continue to hold-in the control knob and press the igniter button. If the

burner does not light, continue to press the igniter button until ignition

occurs. Continue to hold the control knob for 5-10 seconds to allow the

thermocouple to heat up, if the pilot goes out when the control knob is

released, repeat the lighting sequence.

d) Turn the control knob in the anti-clockwise direction to the high position

and the main burner will light.

e) Turn the control knob clockwise to the low position and the gas input

will be reduced to the minimum setting.

f) Slightly depress the control knob and turn to the pilot position, the main

burner will go out but the pilot will remain lit.

g) Slightly depress the control knob and turn to the off position, the pilot

will now be extinguished.

22

Correct position of
fender, located onto
firebox.

3.6 CHECKING FOR CLEARANCE OF COMBUSTION PRODUCTS

a) Close all doors and windows in the room.

b) Light the fire and allow to run for approximately 5 minutes on high

position.

c) After approximately 5 minutes hold a smoke match just inside and

below the centre of the lower front edge of the top of the fire. (It is

recommended that a suitable smoke match holder is used when check

ing for clearance of combustion products). All smoke generated should

be drawn back into the flue. If slight spillage occurs or if in doubt,

repeat the test after a further 5-10 minutes. If the test indicates that

spillage is occurring and the flue restrictor baffle has been fitted, it

should be removed and the test repeated after the fire has cooled.

d) If spillage persists, the flue is not functioning correctly and a fault exists.

If, after investigation the fault cannot be traced and rectified, the fire

must be disconnected from the gas supply and expert advice obtained.

e) If there is an extractor fan fitted any where in the vicinity of the

appliance, or in adjacent rooms the spillage test should be repeated

with the fan running on maximum and all interconnecting doors open.

f) After ensuring that the fire is safe to use it should be left on high

position to fully warm up. During this time a slight odour may be

noticed, this is due to the “newness” of the fire and will soon disappear.

At this stage any minor adjustments to the coals should be made using

suitable long handled tongs and taking care not to damage the coals.

Finally, hand the Installation and Maintenance Instructions and the

Users Instructions over to the customer and explain the operation of the

fire.

SECTION 4

MAINTENANCE

Servicing Notes

Servicing should be carried out annually by a competent person such as a CORGI
registered engineer. This is a condition of the Flavel guarantee schemes.
The service should include visually checking the chimney and fire opening for
accumulations of debris and a smoke test to check for a positive up-draught in the
chimney.
The condition of the coals should be checked and if necessary the whole set

should be replaced with a genuine replacement set.

The burner assembly is designed to be removed as a complete unit for ease of
access. After any servicing work a gas soundness check must always be

carried out.
