7.Is it normal for soot to cover the glass at the beginning of a fire?

ƒThis stove has been built with an air wash system that will help keep the glass clear when the firebox has reached a good operating temperature, and also has a good draft. Cold firebox temperature and poor draft cause soot to form on the glass. Once the firebox temperature and the draft increase, the soot should burn off.

8.What is “draft?”

ƒDraft is the ability of the chimney to exhaust draw by-products produced during the normal process of combustion.

9.What can cause a poor draft?

There are several common factors that can contribute to poor draft: A. Atmospheric Pressure and Air Supply

Atmospheric pressure affecting the draft from a chimney can be outside the home, inside the home, or both. Outside the home, a high-pressure (clear and cool) day generally creates a better draft in the chimney than a low-pressure (overcast and damp) day. Inside the home, household appliances, such as forced-air furnaces or clothes dryers, compete for air, often resulting in inadequate amounts of air available to fuel a fire and creating a condition known as negative pressure. Extreme conditions of negative pressure can cause the combustion by-products to be drawn from the chimney and into the house. This condition is commonly known as “down drafting.”

There are several factors that can affect the amount of air available in the home. Increased amounts of insulation, vinyl windows, extra caulking in various places and door seals can all keep heat in, but may also make a home too airtight. If you are in doubt as to whether or not there is sufficient air in your home for your stove, refrain from using those appliances known to consume air when possible, or open a door or a window to allow some air to enter the home.

B. Environmental Conditions

High trees, a low-lying house location (such as in a valley), tall buildings or structures surrounding your house and even windy conditions can cause pool draft or down drafting.

C. Cold Chimney Temperature

Avoid cold chimney temperatures by burning a hot fire for the first fifteen to forty minutes after building a fire, being careful not to over-fire. If any part of the chimney or parts of the stove start to glow, you are over-firing the stove. Where possible, install a temperature gauge on the chimney so temperature drops can be seen.

D. Chimney Installation and Maintenance

Avoid using too many elbows or long horizontal runs. If in doubt, contact a chimney expert and/or chimney manufacturer for help. Clean your chimney, rain cap(s) and especially the spark arrester regularly, in order to prevent creosote build-up – which can significantly reduce chimney draw and possibly create a chimney fire.

10.Should I close or open the air control fully when shutting down the stove?

ƒWhen shutting down the stove, fully open the air control. This will allow chimney temperatures to remain as high as possible for as long as possible. Remember, cold chimney temperatures create creosote.
