37. Creosote & Soot Formation
When wood is burned slowly, it produces tar and other organic vapors, which combine with expelled
moisture to form creosote. The creosote vapors condense in the relatively cool chimney flue of a slow-
burning fire. As a result, creosote residue accumulates on the flue lining. When ignited, this creosote
makes an extremely hot fire.
The chimney should be inspected at least once every 2 months during the heating season to determine
if a creosote or soot buildup has occurred.
If creosote or soot has accumulated, it should be removed to reduce the risk of a chimney fire.
• Never over fire your stove or appliance.
• The high temperatures caused by over firing can damage the stove and stove pipe and may overheat nearby
combustible walls.
• Do not burn driftwood or treated lumber.
38. Maintenance Procedures (Professional)
It is important that the chimney system be checked and cleaned annually. This is for the safety of the
homeowner and necessary to meet the warranty requirements of Ventis Class-A chimney pipe & Ventis
Forever Firebox. In the case of solid fuel burning appliances, more frequent maintenance may be
required, depending on use. The entire system, from the connection at the appliance to the top of the
chimney must be completely inspected and cleaned.
To clean the chimney lining system it is recommended to perform the following:
1. Remove cap by either removing the 4 bolts on the cap lid or by loosening the clamp band.
2. Select the proper sized chimney brush to clean the chimney. Be sure the brush head passes throughout the
complete length of the liner, including the connectors, terminals and tees.
3. Inspect and clean the chimney cap. Spark arrestors and other screens may be necessary or required in some
areas, but may be susceptible to blockage from creosote or through freezing moisture in areas of low ambient
temperature.
4. Reinstall chimney cap
5. Before the initial firing of the appliance, check the appliance’s operating instructions for initial firing
precautions.
