THREE GOOD REASONS

Why you should have your stove commissioned.

It is vital for the longevity and efﬁcient and safe operation of the stove to have the stove installed and

commissioned by a competent qualiﬁed heating engineer.

1. Installation

The stove should be installed by a competent qualiﬁed heating engineer, who will be conversant with the

Building Regulations and Codes of Practice current at the time of installation. Installation instructions are

supplied with the stove which contain instructions speciﬁc to the appliance.

Incorrect installation may lead to poor performance of the stove and ultimately damage to the appliance.

2. Operating

The operation of the stove should be demonstrated by a competent person, so you, as the operator, are

conversant with the operation of the controls. Instructions on the use of the controls can be found in the

operating instructions supplied with the stove.

Incorrect operation of the controls of the stove may lead to poor performance from the stove and ultimately

damage the appliance.

3. Maintenance

Routine maintenance as described in the operating instructions, supplied with the stove, should be

undertaken by a competent person.

Failure to perform the routine maintenance may adversely effect the performance of the stove and

ultimately damage the appliance.

Registration Form

To be completed by both the owner of the stove and the installing/

commissioning engineer.

It MUST be returned to Euroheat for the registration to be completed.

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 (See appliance data for

ﬂue size), or a precast ﬂue system (See Technical Bulletin TB118).

b) We would strongly recommend that a ﬂue liner is also ﬁtted if being installed into an existing

chimney built with an integral clay liner.

c) If being installed into an existing masonry ﬂue which has NOT been built with an

integral clay liner, a ﬂexible ﬂue liner MUST always be used to line the entire chimney.

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.

d) The chimney should be thoroughly swept prior to installation of the ﬂue liner. However,

if the ﬂue is clean and unobstructed throughout its entire length, it need not be swept.

e) 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.

f) 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.

For further information see the Euroheat Flue Guide IN1087.

g) An approved gas ﬂue terminal MUST be ﬁtted in accordance to the manufacturers

recommendations.

h) Where required a closure plate, of a suitable non-combustible material should be ﬁtted. This

should have an inﬁll panel so as to facilitate removal of any debris that may fall down

the chimney. Even after sweeping soot or debris may continue to fall down the chimney.

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, or within the opening or recess, 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 is to be into a pre cast ﬂue Technical Bulletin 118.

Height of ﬂue less than 3 meters

Height of ﬂue greater than 3 meters

The example above shows an

unacceptable installation into an

unsound and unlined ﬂue. The height

is less than 3 meters and there is no

cowl.

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 8mm 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, unless the

appliance is supplied with its own isolation valve, independent of any appliance control

(gas control valve). 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.

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) In a ﬁreplace recess the stove can be mounted on a 12mm thick decorative hearth or plinth, if

a constructional hearth of the correct dimensions is in place. In a free standing situation, as the

hearth temperature does not exceed 100ºC, a constructional hearth is not required. The stove

can be mounted on a 12mm thick non-combustible decorative hearth of the correct size i.e. a

cast iron plinth, provided that the ﬂoor can support the weight.

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

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

c) There must be a minimum of 300mm (see page11) 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.

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

room is used as sleeping quarters.

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 page 6 to determine which ﬂue systems are suitable for your stove size, having selected a suitable

ﬂue system, please follow the applicable installation method.

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 A SUITABLE DIAMETER

FLEXIBLE FLUE LINER MUST BE USED.

(See page 4 appliance data for ﬂue size)

If ﬁtting to a pre cast ﬂue system refer to Technical Bulletin 118.

The stove is factory assembled for top ﬂue connection. To choose a rear ﬂue option follow the instructions

on page 10.

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

resistant sealant we recommend Fraxﬁll (available from Euroheat Part No: MS9045).

Some so called “Heat Proof” mastiks will only stand a temperature of 300°C before they start breaking down.

In many cases they may give off an obnoxious smell at temperatures much lower than this and therefore

should not be used on this type of installation.

A physical retention method MUST be used at the ﬂue spigot joint with the ﬂue pipe, 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 performance of the ﬂue and the stove passes the necessary ﬂue spillage test.
