Heat & Glo RUTHERFORD-50 Owner's Manual page 24

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 8.1) from the total vertical height to determine the
overall height of the chimney installation.
• Create a schematic for your application similar to Figure
8.1 showing components required (referring to Table
8.1).
• Install a ceiling firestop whenever the chimney penetrates
a floor/ceiling.
NOTICE: A maximum of one offset and return 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 distribution duct
or system. These actions could cause overheating/fire
in the chimney flue, or release of exhaust fumes into the
living areas.
