A. Chimney Requirements
Vertical distances are measured from the base of the fire-
place as shown in Figure 8.2
Minimum overall straight height
Minimum height with single offset/
return
Double offset/return minimum height
Maximum height
Maximum chimney length between an
offset and return
Maximum distance between chimney
stabilizers

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
3.96 m
To determine the chimney components needed to complete your
particular installation, follow the steps below:
4.42 m
• Determine the total vertical height of the fireplace installation. This
dimension is measured from the base of the fireplace assembly
6.1 m
to the point where the smoke exits the termination cap.
15.24 m
• Subtract the effective height of the fireplace assembly from the
6.1 m
overall height of the fireplace installation (measured from the
base of the fireplace to the bottom of the termination cap, 13 ft.
(4m).
10.67 m
• Refer to Table 8.1 to determine what components must be
selected to complete the fireplace installation.
1.83 m
• 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.
