** If the hearth extension material(s) that is intended to be used is
NOT listed on Table 3, the material can still be used if the material(s)
is noncombustible. However, the manufacturer of the material must
provide either the listed k-value per inch or r-value per inch with listed
thickness so that the minimum thickness required for the hearth can
be calculated (per instructions on this Page and/or as specified in the
NFI Certification Manuals).
Note: Also see NFI (National Fireplace Institute) Certification Manuals
showing other acceptable calculation methods and acceptable alternate
materials which can be used.

CLEARANCES - MODEL CI1000HT
COMBUSTIBLE WALL CLEARANCE – USA & Canada
WARNING: It is very important that you observe the minimum
"
(.5")
clearances.
T
L
There are listed clearances for your stove which were determined in a
Laboratory test using various "classes" of stove pipe or chimney. Mini-
mums are first established for the stove itself and increased based on
how much heat is transferred by each class of pipe.
T
M
Position the unit no closer than the minimum clearances to combustible
materials. Check that no overhead cross members in the ceiling or roof
will be cut. Reposition unit if necessary being careful not to move closer
than the minimum clearances.
Minimum Ceiling Height – 7 feet / 2133mm from floor to ceiling.
Single Wall Pipe Without Pipe Shield - CI1000HT

Using single wall 24 MSG black or 25 MSG blued steel connector pipe
with factory-built chimney listed to either UL 103HT or ULC S629. The

Protected Wall Clearance - CI1000HT and CI2000HT
Some local codes will allow reduced clearances when the stove is
installed adjacent to a protected wall system. The variance must be
approved by your local building official. Normally, the protected wall
system is defined as a non- combustible material with a minimum of
1" air space behind. Check your local building codes or with a qualified
installer (Ref. NFPA 211).
