IMPORTANT
.
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.
However, 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 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.
Has 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.

* HETAS Approved
Models indicated above as HETAS approved to a certain flue position are indicated by **
Intermittent operation is when the appliance is used for short firing periods for example 45 minutes to 2 hours.
This is a common operation in warmer weather such as cold spring evenings. The information provided below
where indicated as HETAS approved is from the current CE standards EN 13240:2001 and EN 13240 A2:2004.
The test fuel is wood.
* Air requirement equivalent area. Building regulations Document J, advises that an air supply should be
installed for appliances with a heating output over 5kW. Document J indicates that there should be sufficient
advantageous air for heating outputs below this amount. With modern properties this may not always be the
case and/or more free air may be required. Continuous or intermittent operation will result in different heating
outputs due to the nature of the fuel and the appliance. If in doubt increase the suggested area listed or contact
your HETAS approved engineer for assistance.

Hearths
The stove should stand wholly above a hearth constructed of suitably robust materials and should be able to
accommodate the weight of the appliance and its unsupported flue components. The materials should conform
to local Building Regulations and British Standards.
If the stove is not to stand in an appliance recess, a hearth made of non-combustible board/sheet material or
tiles of at least 12mm thick may be used as long as the floor can accommodate the weight of the appliance
and its unsupported flue components. If it is installed on a wooden floor or similar, the floor must be covered
with a non-combustible material, a minimum of 12mm thick, to a distance of 300mm in front of the stove and
150mm to each side measuring from the closed door of the combustion chamber.
The Hwam range of wood and multifuel stoves have been tested and conform to standards DIN18891 and DIN
18891-A1 where the hearth temperature does not exceed 100°C
For further information on hearths of either glass, granite or slate visit our web site

Do not be tempted to fit the stove into an unsuitable fireplace. Beyond the requirements of Building
Regulations and access to facilitate servicing the stove, providing a setting which will compliment a stove is
not a luxury, it is the practicality of making the most of an investment. A good builder or fireplace specialist
will be able to transform even the most utilitarian of fireplaces. Whether altering its proportions to those of the
“Golden Mean” ideal, see below, or exposing a wooden or stone lintel or simply removing superfluous detailing
for a comparatively small cost, and the result will be a pleasure for many years.
“Golden Mean”
1. The stove must always stand perfectly level. Adjustment screws and/or triangular plastic levelling spacers
may be provided with the stove. The provision of a suitable level hearth within the recess is an important
consideration when planning a fireplace.
2. Sufficient space should be allowed for service work.
3. At least the minimum clearance from inflammable materials and conforming to the current Building
Regulations.
4. Sufficient space around the stove so that the controls may be operated without the risk of injury to the
operator.
5. Mounting brackets should be installed to facilitate the secure fitting of a fire guard, if one is to be fitted to
protect the young, elderly or infirm.
6. Curtains and soft furnishings should be a minimum of 1m from the stoves body or the surface temperature of
these furnishings must not exceed 65°C.
7. The mounting of expensive paintings, mirrors and plasma screen televisions above a fireplace is not
recommended.

Fresh Air System
Instead of letting the air from the room into the stove for combustion, it is possible to take in fresh air from
outside and introduce this directly via a duct into the back of the stove.
Today, many modern dwellings are so airtight to conform with building regulations that it is an advantage to
attach a fresh air intake to the stove. This continually supplies the air for combustion while the stove is in use
but as the air is ducted directly into the back of the stove it stops cold fresh air mixing with the warm air in the
room chilling the room or causing draughts.
This ensures that the air extracter fan outlets in the kitchen and bathroom function optimally without affecting
the air required for combustion. The advantage of this is that a multifuel stove may now be fitted into a room
where an air extracter fan is fitted, however a flue draught test must be carried out with the extracter fan
running at its maximum setting to ensure that the fan is not drawing air from the stove.
The 3310 and 3320 can be equipped with an optional fresh air system. Further information can be found in
the fresh air system’s instruction manual. If you wish to install a fresh air system on your stove, you have the
following options:
1) Stove mounted on the wall: connect the fresh air system on the lower back of the stove.
2) Stove mounted on a plinth: connect the fresh air system either on the lower back of the stove or on the back
of the plinth.
The HWAM 4410 can be equipped with an optional fresh air system. Further information can be found in the
fresh air system’s instruction manual. The following connection options are available:
1) Stove mounted on the wall: connect the fresh air system on the lower back of the stove.
2) Stove mounted on the wall: connect the fresh air system on the lower bottom of the stove.
3) Stove mounted on a plinth: connect the fresh air system either on the lower back of the stove or on the back
of the plinth.

3310/3320 4410
When mounting your wood-burning stove on the wall or on a plinth, it must be placed a minimum of 100mm
above the ground, as measured from the lower edge of the stove.
Note: HWAM 3310 HWAM 3320 and HWAM 4410 must always be mounted on the wall or on a plinth.
Mount the plinth with the open side facing forwards at the location where the stove is to be placed. Place the
stove on top of the plinth so that the two guide pins (1) on top of the plinth fit into the two holes (2) in the
bottom of the stove, and the guide block (3) (3310 & 3320) fits into the hole (4) at the bottom rear edge of the
stove.

If the door opens with difficulty, you may correct
this by greasing the chain wheel boxes (1) and door
hinges (2) with copper grease. You should do this
once every year. Tighten the spring with a special
tool, which can be bought separately. Ask your local
HWAM dealer for assistance.
