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.
Determine the chimney components needed to complete
your particular installation:
• Measure the total vertical height of the fireplace
installation from the base of the fireplace assembly to
the approximate location of the bottom of the termination
cap.
• Subtract the effective height of the fireplace 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 identifies those components and where
used.
• Install a ceiling firestop whenever the chimney penetrates
a floor/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 fireplace to a chimney flue servicing
another appliance. DO NOT connect to any air distribu-
tion duct or system. These actions could cause over-
heating/fire in the chimney flue, or release of exhaust
fumes into the living areas.
