Natural Draft Door
A look at the firebox door. The air inlet is the smaller door with the chain attached. At the top end of the chain is a solenoid that pulls the door open when the water temperature reaches the low limit setting. With the inlet open the fire can burn hotter until the water temperature reaches the high limit setting, then the door closes.
Typically a stove that uses natural draft door, will burn less wood than a force air draft (blower).
This is a picture of a single pump stove. This would be used for heating only one building. Probably a house, however, there is another port on all of our single pump stoves that allow a second pump to be added later to heat another building. You can also see the aqua stat, this is the controller that tells the damper door to open and close as necessary.
This is what it looks like inside the back door of a double pump stove. A double pump stove is used to heat two buildings. The two gate valves pointed downward are the return ports for the water after it has heated the buildings. You can also see the aqua stat. The aqua stat is the controller the tells the draft door to open and close.
Our stoves have been tested and approved by U.L. This certifies that the stove is a safe product. It is also a requirement in most areas for legal installation.
The skids or (skis) hold the stove up without a cement slab. Pouring a cement slab is optional, may look nicer, and be easier to mow or trim around, but is not necessary. Another way we are saving you time and money.
