FAQS

7) Is it normal for soot to cover the glass at the beginning of a ﬁ re?

Your insert has been built with an air wash system that will help keep the glass clear when the ﬁ rebox has reached a

good operating temperature, and has a good draft. Cold ﬁ rebox temperature and poor draft cause sooting of the glass.

Once the ﬁ rebox temperature and the draft increases, the soot will burn off.

8) What is draft?

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

9) What can cause a poor draft?

The most common factors for poor draft are:

a. Atmospheric pressure and air supply

b. Environmental condition

c. Cold chimney temperature

d. Poor chimney installation and maintenance

a) Atmospheric Pressure and Air Supply

Atmospheric pressure affecting the draft from a chimney can be either outside the home, inside the home or

both. Outside the home, a high-pressure day (clear and cool) generally creates a better draft in the chimney

than a low-pressure day (overcast and damp). Inside the home normal household appliances, such as clothes

dryers and forced air furnaces compete for air, resulting in inadequate amounts of air available to fuel a

ﬁ re and create a condition known as negative pressure. Under extreme conditions of negative pressure the

combustion by-products can be drawn from the chimney into the house. This condition is commonly referred

to as down drafting.

There are several factors that impact 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 about whether or not there is sufﬁ cient air in your home for

your insert, curtail from using those appliances known to consume the air where possible, or open a window

or door to allow air to enter the home.

b) Environmental Conditions

High trees, low lying house location such as in a valley, tall buildings or structures surrounding your house

and windy conditions can cause poor draft or down drafting.

c) Cold Chimney Temperature

Avoid cold chimney temperatures by burning a hot ﬁ re for the ﬁ rst ﬁ fteen to forty minutes, being careful not

to over ﬁ re. If any part of the chimney or parts of the insert start to glow, you are over ﬁ ring the insert. 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 chimney, rain caps and especially spark arrester regularly, to prevent creosote

build-up, which will signiﬁ cantly reduce chimney draw and possibly a chimney ﬁ re.

11. Should I close or open the air control fully when shutting down the insert?

Just before shutting down the insert, run on high for a few minutes. This allows the chimney temperatures to remain
