CHIMNEY REQUIREMENTS
A chimney must be the required height above the roof or other obstruction for safety and for proper draft oper- ation. The requirement is that the chimney must be at least 3 ft (91cm) higher than the highest point where it passes through the roof, and at least 2 ft (61cm) higher than the highest part of the roof or structure that is within10 ft (305cm) of the chimney, measured horizon- tally. Refer to Figure 7C.
OVALIZING ROUND STAINLESS STEEL
LINERS
Ovalizing round stainless steel liners to acommodate the liner passing through the damper region of a fire- place is an allowable and acceptable practice.
Ensure that the ovalization is minimized to the extent required to fit through the damper.
