• Minimum overall straight height 20 ft (6.1 m)
• Minimum height with offset/return 20.5 ft (6.25 m)
• Maximum height 90 ft (27.43 m)
• Maximum chimney length between an offset
and return
20 ft (6.1 m)
• Maximum distance between chimney
stabilizers
35 ft (10.67 m)
• Double offset/return minimum height 24 ft (7.32 m)
• Maximum unsupported chimney length
between the offset and return
6 ft (1.83 m)
• Maximum unsupported chimney height above
the fi replace
35 ft (10.67 m)
• Maximum unsupported chimney above roof 6 ft (1.83 m)
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 fi re.
Determine the chimney components needed to complete
your particular installation:
• Measure the total vertical height of the fireplace
installation from the base of the fi replace assembly to
the approximate location of the bottom of the termination
cap.
• Subtract the effective height of the fi replace assembly
(see Figure 8.2) from the total vertical height to determine
the overall height of the chimney installation.
• Create a schematic for your application similar to Figure
8.2 showing components required (referring to Table
8.1). Figure 8.1 identifi es those components and where
used.
• Install a ceiling fi restop whenever the chimney penetrates
a fl oor/ceiling.
NOTICE: A maximum of two pairs of offsets and returns
may be used.
CAUTION! Risk of Fire and/or Asphyxiation! DO
NOT connect this fi replace to a chimney fl ue servicing
another appliance. DO NOT connect to any air distribu-
tion duct or system. These actions could cause over-
heating/fi re in the chimney fl ue, or release of exhaust
fumes into the living areas.
