G. Termination Cap Installation
• Install a cap approved and listed for this fireplace system.
• The bottom of the termination cap must be at least 3 ft
(.91 m) above the roof AND at least 2 ft (.61 m) above
any portion of roof within 10 ft (3.05 m).
If you wish to make a custom shield or barrier, follow
these guidelines:
• Metal is preferred, although any material stiff enough to
hold back the insulation can be used.
WARNING!
Risk of Fire!
Use of cardboard or other
materials that can deflect under humidity or other envi
-
ronmental conditions is not recommended.
• The shield or barrier must be tall enough to extend
above the insulation and prevent blown-in insulation from
spilling into the cavity.
• Maintain specified air spaces around chimney.
• Check instructions and local codes for further details.
Double-check the Chimney Assembly
Continue assembling the chimney sections up as need-
ed. While doing so, be aware of the height and unsup-
ported chimney length limitations given under Section
4.
Check each section by pulling up slightly from the top
to ensure proper engagement before installing the suc-
ceeding sections. If they have been connected correct-
ly, they will not disengage when tested.
