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.

Table 8.1

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.
