General Installation and Servicing Instructions

Safety Precautions

a) It is a requirement of the Gas Safety (Installation and Use) Regulations 1994 that these

instructions, together with the Appliance User Instructions, be left intact with the user.

b) In your own interest, and those of safety, and in accordance with the Gas Safety (Installation

and Use) Regulations 1994, stoves must be installed by competent persons. Failure to install the

appliance correctly could lead to prosecution.

c) It is important to ensure that the ﬂue system into which the appliance is to be installed is

working properly. Products of combustion which enter a room could be a serious health risk. It is

therefore important, in the interests of safety, that Section 3 of these instructions is strictly followed,

together with the legal Statues and Codes of Practice listed below.

d) Any unauthorised modiﬁcation will automatically invalidate any guarantee.

e) The installation must be in accordance with the Gas Safety (Installation and Use) Regulations

1994 and with these instructions, and the relevant parts of the Local and National Building Regulations,

and the recommendations of the following British Standards.

BS 715 : 1993 Metal Flue Systems

BS 1251 : 1987 Fireplace Components

BS 1289 : PT 1 1986 Flue Block Systems

BS 5440 : PT 1 2000 Flues

BS 5440 : PT 2 1989 Ventilation

BS 5871 : PT 1 1991 Installation of Gas Fires

BS 5482 : PT 1 1994 LPG Installations

BS 6891 : 1988 Pipe work Installation

f) The plastic bags used to protect components of this appliance are a potential hazard to

young children, and should be disposed of immediately.

Flue and Chimney Requirements

BS 5440 : PART 1

Before installation of the appliance, the chimney or ﬂue system must be inspected and passed as

suitable. In particular, the following should be checked:

a) This appliance is suitable for installation onto the following ﬂue types:

A suitable sized diameter ﬂexible or fabricated steel ﬂue system, or a standard masonry chimney.

(See appliance data for ﬂue size)

NOTE:

Any steel ﬂue systems used should be manufactured in line with the requirements of BS 715, and installed with due

regard to the manufacturers recommendations.

b) The minimum effective height of the chimney or ﬂue must be 10ft (3 metres) measured from

the hearth to the termination of the ﬂue (chimney pot). If the ﬂue has any non vertical sections the

height should be increased in line with BS 5440 : Part 1.

c) The chimney or ﬂue must be free from any obstruction. Any ﬂue damper or restrictor must be

removed or permanently ﬁxed in the fully open position.

d) The chimney should be swept prior to installation of the stove. However, if the ﬂue is clean

and unobstructed throughout its entire length, it need not be swept.

e) Ensure that only one ﬁreplace is served by the chimney or ﬂue system.

f) Ensure that the chimney or ﬂue system is continuous from inlet to termination.

g) Ensure that the chimney is structurally sound so the combustion products do not come into

contact with combustible materials outside the chimney.

NOTE:

A guide is published by the ‘British Flue and Chimney Manufacturers’ Association’ which contains

general information on chimneys and ﬂues. It can be obtained from:

Sterling House, 6, Furlong, Bourne End, Bucks, SL8 5DG.

Ventilation, BS 5440 : PART 2

Before proceeding further, the following ventilation requirements must be satisﬁed.

a) If the stove is installed in a builder’s opening or ﬁreplace recess that has an air supply entering

from below ﬂoor level, this must be completely sealed off.

b) If there is another gas appliance ﬁtted in the same room, or adjacent area, or extractor fan system,

air conditioning, etc., it will be necessary to refer to BS 6714 and BS 5440 : Part 2 to ascertain the

additional precautions necessary.

If any of the pre-installation checks reveal inadequacies, the installation should not proceed until

they are rectiﬁed.

Do not ﬁt the appliance, seek expert advice.

Installation of the Gas Supply, BS 6891

NOTE:

Ensure that the gas supply is capable of delivering the required amount of gas, and is in

accordance with the relevant current standards.

It is generally preferred to conceal the gas supply by bringing it under the hearth, or through masonry

to the side of the ﬁreplace. Any pipe work in 15mm tube connecting the stove to the main pipe work

should be kept as short as possible with as few ﬁttings as possible to prevent restrictions.

a) Whenever a gas pipe passes through any masonry it must have a sleeve of non combustible

material sealed at both ends to prevent the gas supply from coming in contact with masonry or lime

based mortars.

b) The gas pipe should be adequately supported over longer lengths.

c) Soft copper tubing and soft soldered joints are suitable, providing the tube is not closer than

150mm to the stove casing i.e. the temperature must not exceed 100°C.

d) A means of isolating the gas supply to the appliance must be provided independent of any

appliance control. This may be a gas cock, ideally of the nursery type to prevent children interfering

with the gas supply.

e) Any gas tubing that has been passed through masonry, should be purged to expel any foreign

materials that may have entered the supply.

f) Care should be taken to ensure that pipe work brought through metal structures has been

secured to prevent chafﬁng, but allow for thermal expansion.

Appliance Location

a) This stove must be mounted on a non combustible hearth. The hearth must have a minimum

of 12mm non combustible material thickness.

b) The stove is not suitable for installation into a rear combustible wall, any combustible materials

must be removed from an area of 300mm around the installation of the appliance.

c) There must be a minimum of 450mm from the top of the stove to the underside of any

combustible shelf, Note that for every 50mm increase on clearance, the shelf may project by a further

50mm. See page 8.

d) The appliance must not be installed in a room or space which contains a bath or shower.

e) Ensure that the stove ﬁts neatly into its intended location.

f) Any manufactured surround used with this stove should comply with the appropriate British

Standard.

g) Do not place furniture or furnishing within 1 metre of the stove.

h) Do not obstruct the area directly beneath the stove as this may block the passage of air into

the appliance.

If any of these conditions are not fulﬁlled,

DO NOT FIT THE STOVE until the problem has been rectiﬁed.

Installation of the Stove to the Flue System

Refer to section 3 to determine which ﬂue systems are suitable for your stove size, having selected

a suitable ﬂue system, please follow the applicable installation method.

7.1 Installation to a ﬂue pipe system

IMPORTANT: The ﬂue pipe system should be manufactured in line with BS 715, it should be

either a ﬂexible ﬂue liner or a rigid tubular steel construction, and it must be continuous from

appliance outlet spigot to terminal.

IF IT IS INTENDED TO FIT INTO AN EXISTING MASONRY BUILT CHIMNEY SYSTEM INCLUDING

THOSE THAT ARE TERRACOTTA LINED, A SUITABLE DIAMETER FLEXIBLE FLUE LINER MUST

BE USED.

(See page 4 appliance data for ﬂue size)

The stove is factory assembled for either rear or top ﬂue connection. To choose a different direction

swop the ﬂue blanking plate and the ﬂue spigot. See page 9.

a) The ﬂue system may now be connected to the stove, ensure that all joints are sealed with a

suitable ﬁre resistant sealant. It is also recommended that a physical retention method be used at

the ﬂue spigot joint, self tapping screws being favoured.

Note:

If the ﬂue is to be connected to the rear outlet, there should be no more than 150mm of

horizontal ﬂue run before the ﬂue rises vertically. Under certain circumstances it may be

necessary to use a 45 degree bend directly from the top of the stove, this is acceptable as

long as it does not compromise the drawing power of the ﬂue and the stove passes the

necessary ﬂue spillage test.

Hearth and Fireplace Requirements

Do not be tempted to ﬁt the stove into an unsuitable ﬁreplace. Beyond the requirements of the building

regulations and access to facilitate servicing the stove, providing a setting which will complement

the Harmony is not a luxury, it is the practicality of making the most of an investment. A good builder

will be able to transform even the most utilitarian of ﬁreplaces, whether altering its proportions to

those of the “Golden Mean” ideal, exposing a wooden lintel, stone or simply removing superﬂuous

detailing for comparatively small costs, and the result will be a pleasure for many years.

The measurements are for advice only. In

all installations surrounding inﬂammable

materials must not exceed 80ºC. The

stove must always stand perfectly level

and have sufﬁcient space allowed for

service work.
