A. Chimney Requirements

Vertical distances are measured from the base of the fire- place as shown in Figure 5.2.

	ft	m
• Minimum overall straight height	18	5.5
• Minimum height with offset/return	18.5	5.6
• Maximum height	90	27.4
• Maximum chimney length between an offset and	20	6
return
• Maximum distance between chimney stabilizers	35	10.7
• Double offset/return minimum height	24	7.3
• Maximum unsupported chimney length between the	6	1.8
offset and return
• Maximum straight unsupported chimney height	35	10.7
above the fireplace
• Maximum unsupported chimney above roof	6	1.8

To determine the chimney components needed to complete your particular installation, follow the steps below:

•Determine the total vertical height of the fireplace installation. This dimension is measured from the base of the fireplace assembly to the point where the smoke exits the termination cap.

•Subtract the effective height of the fireplace assembly from the overall height of the fireplace installation (measured from the base of the fireplace to the bottom of the termination cap).

•Refer to Table 5.1 to determine what components must be selected to complete the fireplace installation.

•Determine the number of ceiling firestops, stabilizers, roof flashing, etc. required to complete the fireplace installation.

Note: A maximum of two pairs of offsets and returns may be used.

WARNING

Fire Risk

•Must maintain 2 in. (51 mm) air clearance to insulation and other combustible materials.
