Heatilator BIR50-B Installation Manual page 16

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 4.1) from the total vertical height to determine
the overall height of the chimney installation.
• Create a schematic for your application similar to Figure
4.1 showing components required (referring to Table 4.1).
• Install a ceiling fi restop whenever the chimney penetrates
a fl oor/ceiling.
NOTICE: A maximum of two offset and return 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.
