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 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 replace assembly to
the approximate location of the bottom of the termination
cap.
Subtract the effective height of the 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 identi es those components and where
used.
Install a ceiling restop whenever the chimney penetrates
a 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 replace to a chimney ue servicing
another appliance. DO NOT connect to any air distribu-
tion duct or system. These actions could cause over-
heating/ re in the chimney ue, or release of exhaust
fumes into the living areas.
