B. Chimney Inspection/Cleaning
Frequency: At least twice a year during heating season
or as recommended by a certified chimney sweep
By: Certified chimney sweep
WARNING! Risk of Fire! Ignited creosote is extremely
HOT. Prevent creosote buildup.
Refer to Figure 3.1 to remove/reinstall termination caps.
Creosote - Formation and Need for Removal
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 rela-
tively 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.
WARNING! Risk of Fire! A chimney fire can permanently
damage your chimney system and nearby structures.
In the event of a chimney fire, Hearth & Home Technolo-
gies Inc. recommends
• replacement of the chimney, and
• inspection of the adjacent structure to the provisions of
NFPA Level III inspection criteria.
The chimney shall be inspected at least twice a year
during the heating season to determine when a creosote
buildup has occurred.
When creosote has accumulated it shall be removed to
reduce the risk of a chimney fire.
