duringlightinganddie-downofthere.
• Penetratethehighestpartoftheroof.Thisminimizes
theeffectsofwindloading.
• Locate termination cap away from trees, adjacent
structures,unevenrooflinesandotherobstructions.
• Minimizetheuseofchimneyoffsets.
• Considerthereplacelocationrelativetooorandceiling
andatticjoists.
• Takeintoconsiderationtheterminationrequirementsin
Sections5and6.
Marginal Location:
• Below peak

Constructionofthechasemayvarywiththetypeofbuild-
ing.Theseinstructionsarenotsubstitutesfortherequire-
mentsoflocalbuildingcodes.LocalbuildingcodesMUST
bechecked.
Chasesshouldbeconstructedinthemannerofalloutside

Thechaseshouldnotbreaktheoutsidebuildingenvelope
inanymanner.Allouterwallsneedtobeinsulated.
Buildingcodesrequirefalseceilingandceilingrestops/

• Thechaseisconstructedusingframingmaterialsmuch
thesameasthewallsinyourhome.Avarietyofsiding
materials may be used including brick, stone, veneer
brick,orstandardsidingmaterials.
• In constructing the chase, several factors must be
considered:
- Maintain a 2 in. (51 mm) air space around the
chimney.
- The chase top must be constructed of non-
combustiblematerial.
- Incoldclimates,arestopspacerandatticinsulation
shieldshouldbeinstalledinaninsulatedfalseceiling
at the 8 ft. (2438 mm) level above the replace
assembly.Thisreducesheatlossthroughthechase.
- Incold climates, the walls of the chase should be
insulatedtothelevelofthefalseceilingasshownin
Figure3.4.Thiswillhelpreduceheatlossfromthe
homearoundthereplace.
ThreeexamplesofchaseapplicationsareshowninFig-
ure3.5.
WARNING! You must install false ceilings and ceil-
ing restops at each oor of the chase or every 10 ft
(3.05 m) to control spread of re.
WARNING! Risk of Fire! DO NOT sealareabetweenre
stop opening and chimney pipe except where they enter
the attic or leave the warm air envelope of the home (use
600° F sealant).
WARNING! Risk of Fire! You must maintain a minimum
2 in. (51 mm) air space clearance to insulation and other
materials surrounding the chimney system.
• Insulationandothermaterialsmustbermlysecuredto
prevent accidental contact with chimney system.
• Thechasemustbeproperlyblockedtopreventblown
insulation or other combustibles from entering and
makingcontactwithreplaceorchimney.
• Failuretopreventcontactbetweeninsulationorother
materials and chimney system may cause overheating
andre.
