A. Chimney Requirements

Vertical distances are measured from the base of the fire- place as shown in Figure 8.2

Minimum overall straight height	13 ft	3.96 m
Minimum height with single offset/	14.5 ft	4.42 m
return
Double offset/return minimum height	20 ft	6.1 m
Maximum height	50 ft	15.24 m
Maximum chimney length between an	20 ft	6.1 m
offset and return
Maximum distance between chimney	35 ft	10.67 m
stabilizers
Maximum unsupported chimney	6 ft	1.83 m
length between the offset and return
Maximum unsupported chimney	35 ft	10.67 m
height above the fireplace
Maximum unsupported chimney	6 ft	1.83 m
above roof

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

Warning! Risk of Fire! You must maintain 2 in. (51

mm)air space clearance to insulation and other combus- tible materials around the chimney system. Failure to do so may cause overheating and fire.

NOTICE: You must provide support for the pipe during construction and check to be sure inadvertent loading has not dislodged the chimney section from the fireplace or at any chimney joint.

B. Chimney Termination Requirements

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, 13 ft. (4m).

•Refer to Table 8.1 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.

Caution! Risk of Fire and/or Asphyxiation! DO NOT connect this fireplace to a chimney flue servicing another appliance. Do NOT connect to any air distribution duct or system. These actions could cause overheating/fire in the chimney flue, or release of exhaust fumes into the living areas.
