FIGURE 3G
E. Masonry Chimney Liner
For optimal performance, masonry chimneys used to vent this appliance should be:
1. Lined with a 6 to 8 inches (160 – 200 mm) stainless steel liner.
• Installations into a clay flue without a stainless steel liner may reduce draw which affects performance,
cause the glass to darken and produce excessive creosote.
2. It is recommended that a chimney with a larger diameter than 6-8 inches (160-200 mm) be relined.
•
the oversized flue can cause poor performance and contribute to the accumulation of creosote.
3. Have the chimney cleaned before the appliance is installed and operated.
The following bullets list the more critical requirements for a properly constructed chimney:
WARNING
Fire risk – When lining air-cooled factory-built chimneys:
-
run chimney liner approved to UL 1777 Type HT requirements (2100 degrees F)
-
re-install original factory built chimney cap ONLY
-
DO NOT block cooling air openings in chimney
-
blocking cooling air will overheat the chimney
