INSTALLATION REQUIREMENTS

1.1 CONDITIONS OF INSTALLATION

It is the law that all gas appliances are installed only by a 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. BS 5871 Part 2 Installation of Inset Live Fuel Effect Gas Fires

2. BS 6891 Installation of Gas Pipework

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

4. BS 1251 Open fire place components

5. BS 715 / BS EN 1856-2 Metal flue pipes for gas appliances

6. BS EN 1858 Clay Flue Blocks and Terminals

7. IS 813 : 1996 Domestic Gas Installation (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 and metal flue boxes conforming to BS 715 / BS EN 1856-2. 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.

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

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 170mm. 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

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. If this dimension is

less than 120mm then the fire is not suitable. 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 BFM Europe Ltd. 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 EN 1858. In accordance with BS EN 1858, 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.

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 important 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.

2.1 UNPACKING THE FIRE

Carefully lift the fire out of the carton. Remove the loose item packaging carefully from the front of the appliance. Check the contents as listed :-

Packing Check List

1off Fire box / burner assembly 1off Boxed ceramic base, 2 piece ceramic front rail 11 synthetic coals or

pebbles 1off Loose items bag. 1off each User instruction book and Installation book 1off Flue restrictor baffle (for use in brick built chimneys and large diameter

e.g. 175mm flue applications).

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, insulated pre-fabricated metal flue box to BS 715 / BS EN 1856-2 or Pre-Cast Flue to BS EN 1858

When installing into 125mm (5 inch) diameter lined brick or stone flue, or insulated pre-fabricated metal flue box to BS 715 / BS EN 1856-2 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.

For manual control models (KNVC**MN & KNVP**MN) proceed as follows :-

a) 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 outwards and downwards from the fire box. See

fig. 4 below.

Fig. 4

For Slide Control Models (KNVC**SN / SP & KNVP**MN) Proceed as follows :-

d) Remove the burner heat shield from the front of the fire box to allow

access to the burner. See fig. 5 below.

Fig. 5

e) 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.

f) Remove the burner. To allow burner removal, the control lever operat

ing cable must be removed. The control lever operating cable can be

seen running across the base of the fire, below the burner. To release

the cable, unscrew the cable securing screw located in the centre of the

aluminium operating arm and pull the cable out from its fixing hole.

Release the other end of the cable by pushing the cable forwards to the

right, i.e. into the operating arm so as to release the tension. Pull the

cable nipple out of the retaining hole and remove the cable through the

slot in the operating arm. See fig. 7 overpage

Fig. 6

g) Unscrew the burner assembly fixing screws at either side of the firebox,

and the two fixing screws at the base of the fire (See fig. 6

above).Carefully pull the base of the burner forwards and downwards

from the fuel-bed support panel. The burner can now be removed from

the appliance.

Fig. 7

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. 8a & 8b below for suggested concealed pipe layouts.

Fig. 8a

Fig. 8b

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.

IMPORTANT : Sealing of the Gas Unused Gas Pipe Inlet Apertures

In line with current regulations, it is imperative that the gas supply inlet apertures that are not utilised during the installation are sealed with the foil tape as supplied. Failure to seal these inlet apertures could lead to flame

reversal, which in turn will damage the burner and control systems of the product. Fig. 9 below shows a correctly sealed 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-

h) 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. 10

Fig. 10

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.

i) 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.

j) 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. k) 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).

l) 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. 11 below

Fig. 11

m) 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.

n) 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.

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

is correctly locked into position. On slide control models refit the control

cable To do this, firstly locate the nipple on one end of the cable into

recess in operating arm and then secure the front part of the operating

arm back onto the rear of the operating arm with the retained screw.

This should not be overtightened. Move the control lever fully

downwards and check that the left hand micro-switch operates the

igniter and that the control valve spindle is fully depressed. Move the

control lever upwards to the “off” position and check that the right hand

(cut-off) micro-switch operates. Check that the control lever operates

smoothly and safely.

NOTE : The cable is factory set, and therefore should need no adjustment

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

and secure the trim to the fire using the magnets provided.

q) 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.12) is a diagram to indicate the hole centre positions available on the firebox to facilitate the screw fixing to the fireplace / surround.

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, 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 registered engineer. This is a condition of the BFM Europe Ltd. extended

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 tightness check must always be

carried out.

4.5 Removal of the burner assembly

4.5.1 Prepare the work area (lay down dust sheets etc,)

4.5.2 Lift the fender and ash pan cover out of the way and put them in a safe

location. Remove all of the loose coals and front ceramic rail. Unscrew

the two pozi-drive fixing screws which secure the burner heat shield and

remove it from the fire.

4.5.3 Isolate the gas supply and remove the inlet pipe from the appliance inlet

elbow. To allow burner removal, the control lever operating cable must

be removed. The control lever operating cable can be seen running

across the base of the fire, below the burner. To release the cable,

unscrew the cable securing screw located in the centre of the aluminium

operating arm and pull the cable out from its fixing hole. Release the

other end of the cable by pushing the cable towards the right i.e. into

the operating arm so as to release the tension. Pull the cable nipple out

of the retaining hole and remove the cable through the slot in the

operating arm. Remove the two retaining screws at the base of the

burner unit, and the screw each side of the burner unit. The base of the

burner unit can now be pulled forward, allowing the burner to be

removed outwards and downwards from the fire box. Remove the

burner assembly from the fire.

4.5.4 Refit the burner assembly to the firebox by carefully pushing the bottom

of the burner back into position. Secure using the two screws into the

side frame of the firebox, and two screws into the base.

It is now necessary to refit and correctly tension the operating cable. To

do this, first set the control lever to the horizontal (central position), this

is the position which creates maximum tension in the operating cable.

Refit the operating cable to the aluminium operating arm, firstly locating

the nipple on one end of the cable into recess in operating arm and

then feed the other end through hole in operating arm. Pull the operat

ing cable until it is finger tight and secure with screw into operating arm

(do not over-tighten). Move the control lever fully downwards and check

that the left hand micro-switch operates the igniter and that the control

valve spindle is fully depressed. Move the control lever upwards to the

“off” position and check that the right hand (cut-off) micro-switch

operates. Check that the control lever operates smoothly and safely.

4.6 Removal of the battery ignitor

4.6.1 Remove the burner assembly as above.

4.6.2 Disconnect the ignition lead and earth lead from the igniter. Unscrew the

Battery retaining cap and place battery to one side. Then unscrew

4.7 Replacing the battery

4.7.1 Unscrew Battery retaining cap situated at the front right of the fire and

remove the battery

4.7.2 Replace in the reverse order using a 1.5V AA Alkaline Battery.

4.8 Removing the Oxy-Pilot Assembly

Note: Because this appliance is fitted with an atmosphere sensing ‘OxyPilot’ it is not possible to replace the thermocouple separately, because the thermocouple position is factory set to a tight tolerance. Any replacement of parts on the pilot requires a complete new pilot assembly.

4.8.1 Remove the burner assembly as in section 4.1

4.8.2 Unscrew and remove the thermocouple retaining nut from the end of the

control tap, disconnect the ignition lead from the pilot electrode and the

two inline leads from the microswitch.

4.8.3 Unscrew and remove the two pozi-drive screws which secure the pilot

assembly to the burner. Remove the pilot.

4.8.4 Re-assemble in reverse order and carry out a gas tightness test.

4.9 Replacing the Control Cable

4.9.1 The control lever operating cable can be seen running across the base

of the fire, below the burner. To release the cable, unscrew the cable

securing screw located in the centre of the aluminium operating arm

and pull the cable out from its fixing hole. Release the other end of the

cable by pushing the cable towards the right i.e. into the operating arm

so as to release the tension. Pull the cable nipple out of the retaining

hole and remove the cable through the slot in the operating arm. See

fig. 27 below

Fig. 27

4.9.2 Hold the hexagonal control lever cable locking bush with a spanner

and unscrew the locking screw using a 2mm allen key to release the

cable from the control lever. The control cable can now be removed

from the cable guide tubes.

4.9.3 To fit the replacement cable, thread the end of the new cable into the

long length of p.t.f.e. sleeve (as supplied) , taking care not to kink the

sleeve. Now carefully feed the sleeve and cable into the left hand cable

guide tube until the ends emerge above the control lever. Now thread

the short length of p.t.f.e. sleeve over the end of the cable and thread

the sleeve and cable into the top of the short cable guide tube.

4.9.4 When the end of the cable emerges from the short cable guide tube,

locate the nipple on the other end of the cable into the locating hole in

the aluminium operating arm. Thread the free end of the cable into the

cable retaining hole on the operating arm, but at this stage do not

tighten the securing screw.

4.9.5 Fit the hexagonal control lever cable locking bush onto the control

lever and fit the control cable loosely into the bush in the gap between

the two lengths of p.t.f.e. sleeve. Ensure that the cable is located in the

retaining hole in the locking bush and tighten the screw sufficiently to

retain the cable but still allowing it to slide for adjustment.

4.9.6 It is now necessary to correctly tension the operating cable. To do this,

first set the control lever to the horizontal (central position), this is the

position which creates maximum tension in the operating cable.

Pull the free end of the operating cable through the operating arm until it

is finger tight and secure with screw into operating arm (do not over

tighten).

4.9.7 Slide the operating arm fully to the right hand position and hold in

position, slide the control lever relative to the cable until the cable

retaining screw lines up with the hole in the firebox. This sets the

control lever in the correct position. Hold the hexagonal locking bush

with a spanner and tighten the retaining screw using the 2mm allen key.

Move the control lever fully downwards and check that the left hand

micro-switch operates the igniter and that the control valve spindle is

fully depressed. Move the control lever upwards to the “off” position

and check that the right hand (cut-off) micro-switch operates. Check

that the control lever operates smoothly and safely.
