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.

Air Requirement Equivalent Area as Approved Document J
* HETAS Approved
* 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

Fireplace Design

2/3
2/3
1/3 2/3
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
5
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.

Note: HWAM 3310 HWAM 3320 and HWAM 4410 must always be mounted on the wall or on a plinth.
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.
3310/3320 4410
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.

The door lift mechanism consists of a chain pull placed on either side of the stove and a spring placed beneath the stove. Note: always let a professional grease and repair these parts.
Hwam 3310 and 3320
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.
