2025/2026 | Chimney Safety Institute of America GRADED A+
The rapid oxidation of fuel usually accompanied by the production of heat and light.
Combustion Chamber
A heavily constructed area designed to withstand direct contact with combustion and to optimize
conditions necessary to burn fuel efficiently.
Confined Space

Exhaust
Appliance
Eqipment, usually built in standardized sizes or types, installed or connected as a unit
Approved
Acceptable to the authority having jurisdiction.
American society for testing materials
ASTM
Authority having Jurisdiction
The organization, office or individual responsible for approving equipment, installations or
procedures
Baffle
