IMPORTANT

Since April 2002 only Registered Competent Engineers may install solid fuel fired appliances without
involving the Local Authority Building Control Department. For more details contact HETAS. Euroheat
would suggest only Registered Competent Engineers install Euroheat appliances. If the installer is not a
registered Competent Engineer we would advise that property owners insurance company is contacted to
confirm their insurance is not affected.

 The installation of this appliance must comply with all local regulations, including those referring to National
and European Standards, before it can be operated. The stove is not suitable for a shared flue. For England and
Wales only, the coming into force on 1st April 2002 of SI 2002 No 440 exempts the householder from this legal
requirement for the installation of solid fuel fired appliance whose rated heat output is 50kW or less in a building
having no more than 3 storeys (excluding any basement) if a Competent Engineer is employed who is registered
under the Registration Scheme for Companies and Engineers involved in the Installation and Maintenance of
Domestic Solid Fuel Fired Equipment operated by HETAS Ltd. These registered Competent Engineers may also carry
out associated building work necessary to ensure that the installed appliance complies with Building Regulations
without involving the Local Authority Building Control Department.

 Improper adjustment, alteration, maintenance or the fitting of replacement parts not recommended by
the manufacturer can cause injury or property damage. Do not operate the stove with faulty seals or damaged
glass.

 Due to the high operating temperatures of this appliance it should be located away from pedestrian traffic
and away from furniture and draperies. Do not store paper or wood near the appliance. Any mats and rugs put
in front of the stove should be fire proof and secured to prevent the possibility of tripping.

 Advise all persons as to the stove’s high surface temperatures. If it is possible for children or infirm adults to
come into contact with the stove, fit a suitable fire guard.

 It is imperative that all air passageways into, out of, and within the appliance are kept clean. All permanent
ventilation into the room provided for the stove must remain clear and unobstructed at all times. Consideration must
be given to the need for extra ventilation if another heating source needing air is to be operated simultaneously.
If an extraction fan is proposed to be fitted to a connecting area of the house, after the stove has been installed,
professional advice should be sought from a qualified engineer.

 The user should be advised that the appliance should be inspected and the boiler air ways cleaned regularly
and the chimney cleaned at least annually. More frequent cleaning may be required and the advice of a qualified
chimney sweep should be sought.

 Our range of stoves is capable of operating with outstanding efficiency if the flue system is correct. Because
so little heat is wasted to the flue it is possible that moisture within the products of combustion will condense if
the heat losses within the flue way are too great and allow the flue gasses to cool. For this reason we recommend
that the stove is fitted with a suitable flue liner, the same diameter as the flue spigot, to prevent the possibility
of acidic damage to the fabric of the chimney and damage to the stove which will reduce the longevity of the
stove.

 When correctly installed, the stove is designed to produce heat, safely. It cannot do so if the installation is
less than absolutely stable, constructed of materials suitable for such an installation and consideration has not
been given to the possibility of people with less than ideal common sense operating it.

 Have the existing chimney swept by a chimney sweep, although you will be lining the chimney, any deposits
left in the chimney will cause problems and may become a fire hazard.

 Your attention is drawn to the precautions and responsibilities under the Health and Safety at Work Acts, and
whatever new legislation being introduced during the life of this document.

The Model Range Explained

Nestor Martin and Euroheat insist on progressive development to produce products which are market leading.
Our aims are to produce stoves with the latest innovations, user friendly operation and highly efficient for lower
cost operation.

This manual offers installation information for the range of Nestor Martin Harmony boiler stoves. In some cases
you find references in this document to the model size rather than the models exterior design. Although the
exterior clothes change between model sizes the internal workings are the same.

Model Identification

You will see on the front page of this document a label which confirms which model you have. This label also
advises you of the stoves unique serial number. This information is also attached to your stove for reference.

Important

Please ensure the warranty registration form is completed if you are the installer and confirm with the user that it
is their responsibility to return it to Euroheat. In this way the model and its history will be recorded for reference
in the future.

*Free Air Requirement

Air requirement equivalent area. Building regulations Document J, advises that an air supply, permanently open
vents, should be installed for appliances:

If design air permeability >5.0m³/(h.m²) then 550mm²/kW of appliance rated output above 5kW
or
If design air permeability <5.0m³/(h.m²) then 550mm²/kW of appliance rated output

Equivalent air is as measured according to the method in BS EN13141-1:2004

It is unlikely that a dwelling constructed prior to 2008 will have an air permeability of <5.0m³/(h.m²) at 50pa
unless extensive measures have been taken to improve air-tightness.

Bends in flue pipe

Top exit

A flue pipe shall have no more than four bends, each providing a maximum change of direction of 45º, there
should be not more than two of these bends before an access point for sweeping and two between a sweeping
point and the flue terminal.

On top exit stoves, ideally the flue should rise vertically 1 meter before the first bend. It is permissible to have a
bend no greater than 45° from the top flue outlet, or off the top of a “T” piece, as long as it does not adversely
effect the flue draught.

Back exit

For a back outlet application using a “T” piece, this should be treated as two 45º bends. If a “T” piece is to be
used, the horizontal flue run from the back outlet of the stove shall only be used to connect the stove to a “T”
piece and shall not be more than 150mm in length.

Chimney and Flues

For information on flues see the Technical Guide IN1173 supplied with the stove.

Adequate access for sweeping must be provided.
It is not possible to sweep a flue through a Harmony multifuel boiler stove.

Carbon Monoxide Alarms

Where a new solid fuel stove is installed in a property a carbon monoxide alarm should be located in the same
room where the appliance is located:

a. on the ceiling at least 300mm from any wall or, if it is located on a wall, as high up as possible (above any
doors and windows) but not within 150mm of the ceiling; and

b. between 1m am 3m horizontally from the appliance.

Carbon monoxide alarms should comply with BS EN 50291:2001 and be powered by a battery designed to
operate for the working life of the alarm. The alarm should incorporate a warning device to alert users when the
working life of the alarm is due to end. Mains-powered BS EN 50291 Type A carbon monoxide alarms with fixed
wiring (not plug in types) may be used as alternative applications provided they are fitted with a sensor failure
warning device.
