INSTALLER GUIDE

1. SAFETY

This product uses fuel effect pieces containing Refractory Ceramic Fibres

(RCF), which are man-made vitreous silicate fibres. Excessive exposure to

these materials may cause irritation to eyes, skin and respiratory tract.

Consequently, it is important 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 RCF articles is kept to a minimum, during installation and

servicing we recommend that you use a HEPA filtered vacuum to remove any

dust and soot accumulated in and around the stove before and after working on

the stove. 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. RCF waste is classed as a stable, non-reactive

hazardous waste and may be disposed at a landfill licensed to accept such

waste. Protective clothing is not required when handling these articles, but we

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.

Installer

Tiger stoves are efficient appliances giving off convected, conducted and radiated

heat. All the surfaces of the stove - except the controls - are working surfaces and

become hot in use. They must not be touched or have any combustible objects or

materials placed on or near them. A fire guard complying with BS 8423 should be

fitted for the protection of young children, the elderly, the infirm or pet animals.

The appliance is fitted with a flue safety device. If the appliance closes down after a

period of operation for no apparent reason, the consumer should be informed to stop

using the appliance until the installation and appliance have been thoroughly

checked. Under no circumstances should the flue safety device be altered or

bypassed in any way. Only a genuine manufacturer’s replacement part should be

fitted.

Before continuing any further with the installation of this appliance please read the

following guide to manual handling:

The lifting weight of this appliance is 70 kg. We therefore recommend that two

people should be sufficient to lift the stove. If fitting or moving the stove alone we

recommend the use of suitable lifting apparatus.

When lifting always keep your back straight. Bend your legs and not your back.

Avoid twisting at the waist. It is better to reposition your feet.

Avoid upper body/top heavy bending. Do not lean forward or sideways whilst

handling the stove.

5. GENERAL INSTALLATION REQUIREMENTS

Regulations, Standards and Law.

The installation must be in accordance with these instructions.

For the user’s protection, in the United Kingdom it is the law that all gas appliances

are installed by competent persons in accordance with the current edition of the Gas

Safety (Installation and Use) Regulations. Failure to install the appliance correctly

could lead to prosecution. GAS SAFE REGISTER and CORGI require their members

to work to recognised standards.

In the United Kingdom the installation must also be in accordance with all the relevant

parts of local regulations.

BS 5440 Part 1

BS 5440 Part 2

BS 4543 Part 2

BS 5871 Part 1

BS 6891

BS 8303

In England and Wales, the current edition of the Building Regulations issued by the

Department of the Environment and the Welsh Office.

In Scotland, the current edition of the Building Standards (Scotland) Regulations

issued by the Scottish Executive.

In Northern Ireland, the current edition of the Building regulations (Northern Ireland)

issued by the Department of the Environment for Northern Ireland.

INSTALLER GUIDE

Figure 5.

Page 11

In the republic of Ireland the installation must be carried out by a competent person

and also conform to the relevant parts of:

a) The current edition of IS 813 “Domestic Gas Installations”

b) All relevant national and local rules in force.

Where no specific instructions are given, reference should be made to the relevant

British Standard Code of Practice.

The Hearth.

The appliance must be mounted on a non-combustible hearth (N.B. conglomerate

marble hearths are considered as non-combustible). The hearth material must be at

least 12mm thick. The hearth must protrude at least 150mm (6”) in front of the stove

body. In most buildings with solid concrete floors this requirement will be met by the

floor itself.

Clearances.

Clearances from combustible and non- combustible materials must be at least those

shown in figure 6.

IMPORTANT: Reducing the clearance distance at the rear of the stove (especially

with non-combustible surfaces) can result in the stove switching off. This occurs when

the thermal switch operates due to insufficient cool air.

Flue / Chimney.

 The stove is approved for use with 125mm (5 inch) diameter insulated flue.

 Before you install the stove make sure the chimney flue outlet is correctly

positioned to align with the flue outlet on the stove and that the chimney is in good

condition. If not, a chimney liner must be installed or a suitable class 2 gas flue used.

A draught is necessary to ensure the products of combustion are fully evacuated.

Figure 6. Dimensions and Clearances

INSTALLER GUIDE

Connect and seal the stove flue collar to the chimney using full depth of collar. The

flue must have a minimum effective height of 3 metres (10ft), however to, to ensure

optimum performance we recommend 3.66 metres (12ft) or higher. The flue must be

free of obstruction and any dampers must be fixed in a permanently open position.

Ensure that the chimney is not closed and that it has been swept prior to the stove

being installed. Make sure that rain, birds or any foreign bodies cannot get into the

chimney and cause blockage or damage. This problem can normally be overcome by

fitting an approved Gas Cowl. It is essential to the effective running of your stove that

the chimney draws properly and allows the products of combustion to escape.

Ventilation.

 Adventitious ventilation is usually sufficient to satisfy the ventilation requirements

of this appliance. In GB reference should be made to BS5871 Part 1 and in IE

reference should be made to the current edition of IS 813 “Domestic gas installations”

which make clear the conditions that must be met to demonstrate that sufficient

ventilation is available.

 An extractor fan may only be used in the same room as this appliance, or in any

area from which ventilation for the appliance is taken, if it does not affect the safe

performance of the appliance. Note the spillage test requirements detailed further on

in this manual. If the fan is likely to affect the appliance, the appliance must not be

installed unless the fan is permanently disconnected.

Location.

 This appliance must not be installed in a private garage or any room, which

contains a bath, shower or where steam is regularly present.

Propane gas.

 Propane gas appliances must not be installed in a cellar, basement or other room

which is built entirely below ground level.

(See Gas Safety (Installation and use) Regulations).

Gas connection.

 A nut and olive are provided for an 8mm pipe inlet connection to the elbow at the

bottom front of the appliance. The elbow can be rotated to allow a connection from

any direction. The elbow includes a valve for isolating the gas supply.

 The supply pipe must be rigid material. Flexible pipe must not be used.

 Note: Prior to connecting the gas supply it is advisable to blow out the gas

supply so that any dirt which may be present in the pipe is cleared and cannot

enter the gas valve or pilot burner and so cause a blockage

 With the supply connected pressure check the installation pipework for gas

soundness. In the United Kingdom check in accordance with the current edition of

BS6891. In the Republic of Ireland check in accordance with the rules in force.

INSTALLER GUIDE

Securing the stove.

The stove is supplied with two screws and plugs. Secure

the stove in place through the holes in the rear feet.

Fitting the ceramic fuel effect.

The installer and owner guide for the ceramic fuel effect

is supplied with the ceramic fuel effect. It is important that

the installer guide for the ceramic fuel effect be placed

inside or attached to this guide and handed to the

customer following completion of the ‘Final review’

section.

Fitting the fire bar.

Locate the fire bar as in figure 7.

Be careful not to damage the ceramic fuel effect when

fitting the fire bar.

6. OPERATING THE STOVE

Pre-lighting checks.

 Ensure all the building work and flue sealing is complete.

 Ensure the fire bar is fitted.

 Ensure all the coals are correctly placed.

 Ensure that the stove door is closed and secured.

 Ensure that the stove door is completely sealed.

 Lock the stove door handle with the locking screw using the key supplied.

Lighting the burner.

 If closed,open the isolating valve at the inlet elbow.

 Depress the control knob and rotate it SLOWLY anticlockwise to the pilot ignition

position. A 'click' will be heard as the integral piezo operates.

 Turn the control knob clockwise to the 'Off' position. Repeat this operation until a

flame appears at the pilot. There may be a delay before the pilot lights due to air

being purged from the system. When a flame appears at the pilot keep the control

knob depressed and hold the pilot ignition position for five seconds. When the control

knob is released the pilot flame should remain lit.

Operating the burner.

 When the pilot burner is operating properly, gradually turn the control knob anti-

clockwise to 'HIGH' (Depress the knob slightly to get past the pilot ignition position).

The main burner should now light. Depress the control knob slightly to release from

the 'HIGH' position and turn back (clockwise) to 'LOW'. While turning, the burner

flames should gradually become lower but remain alight. Depress the control knob

slightly to release from the 'LOW' position and turn back (clockwise) to the ‘Pilot

Page 13

INSTALLER GUIDE

Figure 7.

ignition’ position. The main burner should extinguish but the pilot should remain alight.

Depress the control knob slightly and turn back (clockwise) to turn OFF.

This will extinguish the pilot.

Inlet pressure check.

The appliance is pre-set to give the

correct heat input at the inlet

pressure shown in section 2 of this

manual. No adjustment is

necessary.

 Check the inlet pressure by

fitting a pressure gauge at the test

point. The test point is on the inlet

‘T’ connector (See figure 8). Check

the pressure with the appliance

alight and set at maximum output.

 After checking, turn off the

appliance. Remove the pressure gauge and replace the test point sealing screw.

 Relight the appliance. Turn to the maximum output position and test around the

sealing screw for gas soundness with a suitable leak detection fluid.

Check for spillage.

 Close all doors and windows in the room containing the appliance.

 Light the appliance and turn the control knob to the ‘HIGH’ position.

 Leave the appliance on for five minutes.

 A smoke match should be placed close to base of the diverter box. The

installation is satisfactory if the smoke is drawn into the appliance/ flue way. Do not

use a lighted match or a naked flame.

If the smoke is not drawn into the appliance leave the appliance alight at the

maximum setting for a further ten minutes and then repeat the test. If the smoke is

still not drawn into the appliance then disconnect the appliance and seek expert

advice.

 If the above test is satisfactory open all internal connecting doors, hatches, etc. in

the room. Keep all doors and windows that open to the outside of the building closed.

Recheck for spillage as above. If an extractor fan is installed in the same room as the

appliance or a connecting room, check that spillage does not occur with the fan

operating and all doors and other openings between the fan and the appliance open.

If the smoke is drawn into the appliance, continue with the installation. If the test is

not satisfactory disconnect the appliance and advise the customer of the cause

of failure.

Page 14

INSTALLER GUIDE

Figure 8.

Flame supervision and spillage monitoring system.

The pilot unit incorporates a system that will automatically shut off the gas supply if

the pilot flame goes out. Check that the system operates properly as follows;

 Light the appliance. Set at the “HIGH” position and leave for one minute.

 Turn back to “OFF” to extinguish the pilot. Note the time when the pilot goes

out. Listen for a snap sound at the gas tap. Note the time when the sound is

heard. This sound is caused by an electromagnetic valve shutting off the gas supply

through the tap. The valve is located in the body of the tap. The valve should operate

within 60 seconds of the pilot going out. If the valve does not operate within this

time limit do not allow the appliance to be used until the fault has been corrected.

This monitoring system must not be adjusted, bypassed or put out of

operation.

This monitoring system, or any of its parts, must only be exchanged using

Valor Fires authorised parts.

7. FINAL REVIEW AND SERVICING

Final Review.

 Hand the literature pack with this guide to the customer.

 Visually inspect the appliance. Clean off any marks incurred during installation.

 Advise the customer how to operate the appliance. Point out that lighting

instruction details are on the metal plate attached to the burner at the bottom of the

appliance.

 Explain to the customer that the appliance has a flame failure & spillage

monitoring system. Point out the explanation of this system shown in the owner guide

under “Operating your stove”. Advise that if the stove goes out for any reason, wait at

least ten minutes before relighting. Stress that if the monitoring system repeatedly

shuts off the stove, the appliance should be switched off and a specialist should be

consulted.

 Advise the customer that they should read their owner guide before operating the

stove and always follow the advice in the section headed “Cleaning your stove”.

 Stress that no extra ceramic fuel effect pieces must be added over and

above those supplied with the appliance and that any replacements must only

be the authorised spares. Warn that ignoring this advice could cause

incomplete clearance of the products of combustion with consequent health

hazards.

 Advise the customer that the appliance will operate to its maximum potential if the

flue is primed during the first 20 – 30 minutes of use. To do this, simply turn the

control knob to its highest setting. This will also burn off any carbon deposits that may

have formed during previous use.

If using the appliance for long periods it is beneficial to change between settings. This

will also help to remove any carbon deposits that may form during use.

 Recommend that the appliance should be serviced by a competent person at least

annually.

Page 15

INSTALLER GUIDE

 If the appliance is in premises in the United Kingdom occupied by a tenant, point

out that by law a landlord must have any gas appliance, flue and pipework which is

situated in a tenant’s premises checked for safety at least every 12 months.

 Explain to the customer that when operating the stove for the first time, some

vapours may be given off which may cause a slight odour and could possibly set off

any smoke alarms in the immediate vicinity. These vapours are quite normal with new

appliances. They are totally harmless and will disappear after approximately twelve

hours use.

 Inform the customer that the Serial number for the appliance is located on

the metal plate attached to the burner at the bottom of the appliance

underneath the burner module.

Servicing.

 Always turn off the gas supply and allow to cool completely before commencing

any servicing.
