Chimney Requirements - Heat & Glo PIER-40 Owner's Manual

A. Chimney Requirements
Measure vertical distances from the base of the fi replace
as shown in Figure 8.2.
• Minimum overall straight height
• Minimum height with offset/return
• Maximum height
• Maximum chimney length between an offset
and return
• Maximum distance between chimney
stabilizers
• Double offset/return minimum height
• Maximum unsupported chimney length
between the offset and return
• Maximum unsupported chimney height above
the fi replace
• Maximum unsupported chimney above roof
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.
