BURNING PROCESS

In recent years there has been an increasing con- cern about the quality of our air. Much of the blame for poor air quality has been placed on the burning of wood for home heating. In order to improve the situa- tion, we at Heat-N-Glo have developed cleaner burn- ing wood stoves that surpass the stringent require- ments for emissions established by our governing agencies.

Properly operated and maintained your WS-150 or WS-250 wood stove will obtain the peak efficiency and lowest emissions possible, resulting in better air quality for your community and more heat output per pound of wood. Improper operation and maintenance may cause any wood burning unit to release more particulate and adversely affect the environment.

It helps to know a little about the actual process of burning in order to understand how to operate the stove for best performance. The first stage of burn- ing we will call the kindling stage. In this stage, the wood is heated to a temperature high enough to evaporate the moisture which is present in all wood. The wood will reach the boiling point of water (212°F) and will not get any hotter until the water is evapo- rated. This process takes heat from the coals and tends to cool the stove. Fire requires three things to burn: fuel, air and heat. So, if heat is robbed from the stove during the drying stage, the new load of wood has reduced the chances for a good clean burn. For this reason, it is always best to burn dry, seasoned firewood. When the wood isn’t dry, you must open

the air controls and burn the stove at a high burn set- ting for a longer time to start it burning. The control on the right side of the stove is called the primary con- trol; it is used mainly during the kindling stage of burn- ing, or when burning the stove at a high burn setting. It should be closed (pulled outward) for lower burns.

The next stage of burning, the secondary stage, is the period when the wood gives off flammable gases which burn above the fuel with bright flames. During this stage of burning it is very important that the flames be maintained and not allowed to go out. This will in- sure the cleanest possible fire. If you are adjusting your stove for a low burn rate, you should close down the air to the point where you can still maintain some flame. If the flames tend to go out, the stove is set too low for your burning conditions. The air control in the center of the stove, beneath the ash catcher, is the one used to adjust the stove for lower burn rates. This is called the secondary control. Pulling either control towards you closes it, pushing it in opens it.

The final stage of burning is the charcoal stage. This occurs when the flammable gases have been mostly burned and only charcoal remains. This is a naturally clean portion of the burn. The coals burn with hot blue flames. It is very important to reload your stove while enough lively hot coals remain in order to provide the amount of heat needed to dry and rekindle the next load of wood. It is best to open the air controls for a short while before reloading. This livens up the coal bed. Open door slowly so that ash or smoke does not exit stove through opening. You should also break up any large chunks and distribute the coals so that the new wood is laid on hot coals.

Following these standards for operation and mainte- nance is a responsible action for the choice to heat your home with wood. In addition, you will also ex- tend the life of your wood stove for many years of use and enjoyment.

PRIMARY AIR SYSTEM The primary combustion air enters at the rear of the fire- box through the primary air tubes. For more heat push control in, for less heat pull control out.

SECONDARY AIR SYSTEM

The secondary air enters at the upper front of the firebox, near the top of the glass door. This preheated air supplies the necessary fresh oxygen to mix with the unburned gases, helping to create secondary, tertiary and quaternary combustions. This air is regulated by the secondary control. For more sec- ondary air push control in, for less sec- ondary air pull control out.
