Definition of Terms

A

Ash pot: Storage place for ash produced by the wood-burning stove. The ash can be sucked out with an ash pan.

Automatics system: HWAM is the only producer of wood-burning stoves with automatic air regulation systems. This basically means that optimal efficiency is obtained through an optimal control of air adjusted for the different phases in the combustion process. (Please refer to the section on automatics).


B

Baffle Plate: To create heat in the stove for warmth in the room, the heat is to be set down by 1-2 baffle Plates in the stove.

Built-in bushing: A built-in ring that is used to wall up a chimney, where the smoke pipe is connected to the chimney.


C

Chimney draft: A chimney with proper draft is necessary for the wood-burning stove to function optimally. The chimney functions as the wood-burning stove’s ’motor’. A good chimney normally has a draft of 12-14 Pa.

Chimney’s internal diameter: The size of the pipe/channel inside the chimney. Most chimneys have an internal diameter of Ø15 cm.

Convection stove: A convection stove distributes warmth evenly throughout the entire area that is to be heated. This means that the entire house will be delighted by the warmth. Warmth is lead out through the channels, ascends, and automatically spreads around while cold air is sucked in. This is how the stove provides evenly-distributed warmth. A convection stove does not become terribly hot on the surface, and furniture can therefore be placed near the wood-burning stove.


D

DAPO: The association of Danish producers of fireplaces and wood-burning stoves. DAPO is an industry association consisting of five Danish companies that produce fireplaces and wood-burning stoves.

Distance from furniture: The distance between furniture pieces and the wood-burning stove. A stove generally emits the most heat from the glass parts.

DS approval: Prior to the European Norm, stoves were approved by a Danish Standard (DS). The European Norm replaced the DS.


E

Effect: The effect is the wood-burning stove’s efficiency. A wood-burning stove’s effect is indicated in kilowatts (kW).

EN approval: Most wood-burning stoves from HWAM are approved in accordance with a European Norm (EN-13240). This European norm applies to all member states of the EU. Beyond these approvals, HWAM has also followed the sharp Nordic standards.

Exhaust pipe: The exhaust pipe in the stove is the opening through which smoke is led to the chimney. It is normally a hole with a diameter of 15 cm.


F

Flammable material: Any material that can be ignited. This can be wooden boards, gypsum boards with wooden frames, etc.

Floor plate: Placing a plate underneath the stove is required for flammable materials such as wooden floors. The plate must be of a size that is in accordance with the requirements set forth in the instruction manual. The floor plate is available in a number of materials that match the stove and your house’s style.

Fresh air system: A fresh air system can be purchased for most HWAM wood-burning stoves, which introduces fresh air from the outside. Two different systems are available: The first introduces air into the room/convection so that there is always an air balance in the room. The second is a closed system, which means that fresh air comes directly into the automatics system. It is essential that there is always a sufficient amount of air in the room where the wood-burning stove is located.

Full form: A full form is a smoke pipe that can be positioned on top of the wood-burning stove. The advantage of using a full form is that there is no resistance in the smoke pipe, and it generally matches the round shapes of the wood-burning stove itself.

K

kW: kW is an abbreviation for kilowatt. As a rule of thumb, a house with a floor-to-ceiling height of 2.40 m heats 1 kW, so that: outstanding insulation = approximately 25 m²; good insulation = approximately 25 m²; good insulation = approximately 15 m²; and poor insulation = approximately 10 m².


N

Nominal draft: The chimney draft when the wood-burning stove is heated up and the chimney is functioning normally.


P

Pa.: Pa. = Pascal. Unit of measurement for chimney draft. It can be measured electronically or by using a water gauge.

Primary and secondary air: For optimal use of the wood-burning stove, air must be introduced for combustion. In the lighting phase (start-up phase) primary air must be introduced through the shaking grate at the bottom of the combustion chamber. This air comes through the channels from the bottom of the stove, and is introduced through the draft from the chimney. In the combustion period, air is introduced over the fire (secondary air) for combustion of the smoke gasses.

Pane Flush Air channel that sends heated air across the glass in the combustion chamber. The air prevents soot build-up from collecting on the glass. A number of HWAM wood-burning stoves have a "three-sided pane flush" feature. This means that air comes from both sides and the top.


R

Regulator knob: The regulator knob is the wood-burning stove’s effect regulation device. It offers the possibility of regulating the heat from minimum to maximum. It is normally in a set position that suits the room(s) that the wood-burning stove must heat. The automatics system sees to the regulation of air that introduced into the combustion chamber.

Recommended vermiculite/skamolex/skamol: In most stoves, insulation in the combustion chamber is made of fire-proof stone or vermiculite/skamolex/skamol. Most wood-burning stoves are insulated with skamol. The advantage of using skamol is that it insulates 6-8 times better than fire-proof stone.

Soapstone Stone that can be used to tile the wood-burning stove. There are a number of different options for covering the wood-burning stove: the base, the plate to the top and the entire stove (please see the product overview). The soapstone comes from Finland and South America.


S

Senotherm paint: The wood-burning stove is treated with a heat-resistant paint called senotherm. It is possible to repair scratches or corrosion with senotherm paint.

Senotherm can be purchased from your local dealer.

Shaking grate: A grate that can remove ash from the combustion chamber to the ash pan or ash pot.

Smoke pipe: To connect the chimney to the wood-burning stove, a smoke pipe must be used. A smoke pipe is a channel that is either positioned in the rear or the front of the stove, and can lead out from behind or in front of the stove.

Soapstone tiling: In HWAM’s product assortment, there are some stove’s covered with soapstone. The wood-burning stove has soapstone on the sides and on the top.

Stoking: Stoking can take place during the lighting phase, in which firewood is placed in the combustion chamber, or simply by adding more firewood to the fire. Recommended amounts of wood (in kg) are stated in the instruction manual.


T

Top cover: A top cover is a decoration that can be placed on top of the stove so that the top plate is level.
