2.Using the existing chimney as an air inlet
The following installation procedure is not covered under the ANSI Z21.88 test method and
product certification. Use of an existing chimney as an air intake must be specifically approved by
your gas supplier and the local code Authority Having Jurisdiction
The chimney flue must be carefully sealed from the room environment. Fabricate a plate of non-
combustible material and carefully fit it to the damper area with high temperature sealant.
This stove is certified for use with a coaxial venting system. ANSI Z21.88 standards state
that the maximum leakage rate for the venting system is 32 SCFM @ .06" w.c. This leakage
must be accounted for if you use the chimney for intake air.
NOTE: All joints must be sealed. Leakage around the damper seal must be avoided.
WARNING: This installation may not work in a negative pressure environment, or if a
seal cannot be attained. If sooting, ghosting of flame occurs, please check and repair
leakage of chimney system.
