Determinethechimneycomponentsneededtocomplete
yourparticularinstallation:
Measure the total vertical height of the fireplace
installationfromthebaseofthereplaceassemblyto
theapproximatelocationofthebottomofthetermination
cap.
• Subtracttheeffectiveheightofthe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

8.1).Figure8.1identiesthosecomponentsandwhere
used.
• Installaceilingrestopwheneverthechimneypenetrates
a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 replace to a chimney ue servicing
another appliance. DO NOT connect to any air distribu-
tion duct or system. These actions could cause over-
heating/re in the chimney ue, or release of exhaust
fumes into the living areas.
