• CO-Linear Direct Vent – a direct vent framework comprising of two separate funnels of a similar width. One funnel for exhaust and the other for ignition air.
• Corbel – units of stonework projecting from upward and outward from the essence of a divider or chimney in courses to shape a help or edge for a shaft, crossbeam, or other parts.

• Smoke Shelf – prevents downdrafts from the outside from interfering with updrafts carrying smoke and gases.
• Soot – a black, carbonaceous substance produced during incomplete combustion of coal, wood, oil, etc., rising in fine particles and adhering to the sides of the chimney or pipe conveying the smoke: also conveyed in the atmosphere to other locations.
• Thimble – fixed or removable ring, cylinder, or coating generally situated destitute where the chimney connector goes through a divider and enters a fireplace or vent.
• Vent – consistent entry from the flue collar to the draft hood. flue gas temperatures at the outlet do not surpass 600 degrees.
• Video Scan – fusing a shut circuit camcorder and screen, for reviewing the inside of pipes and other difficult to reach zones. This gives a definite piece of the assessment cycle.
