3.) DETERMINE IF THE CORRECT SIZE LINER WILL
FIT INTO THE CHIMNEY
- Since chimneys are usually very sooty and dusty, it is advisable to
remove or cover your furniture, rug, etc. for the duration of the cleaning
and installation of the liner. The Stainless Steel Flexible Liner can be
installed within the existing flue tile or the flue tile can be removed. It
is extremely important that the correct size liner will fit into the chimney.
Certain factors, such as chimney construction and offsets in the
chimney, may change the size of the interior of the chimney. It is best
to prove the interior of the chimney before trying to install the chimney
liner. This can be done by lowering a short piece of the intended size
liner down the chimney to see if it will pass all the way to the bottom.
You can also use a liner guide cone to accomplish this. If the chimney
liner will need to be insulated this will affect the required dimensions
needed to install the liner. If the round configurations needed to vent
the appliance will not fit the liner may be formed to an oval configuration
to fit, however ovalizing the liner will change the cross sectional area.
)
- This system is approved in Canada and the United States with an
approved Ceramic Insulation Wrap to reduce the clearance to com-
bustible construction outside of a masonry chimney only. The clear-
ance between the masonry chimney and combustible materials is de-
pendent on the installation configuration as shown in Table 1 and Fig-
ure 2.
- An approved insulation wrap with 8 lb. density, 1/2” foil faced ce-
ramic fibre blanket will enhance the performance and life of the
chimney when:
- The installation needs to meet the requirements of UL1777 at zero
clearance to combustibles;
- The chimney being relined is located outside;
- Low flue gas temperatures are anticipated.

*Insulated Stainless Steel Flexible Liner with an approved Insulation
Wrap of 8 lbs. density, 1/2” foil faced ceramic fibre blanket such as our
Insulation Wrap Kit - *RF101 (*denotes diameter from 5” to 8”).
*Please note: While insulation is not required for every application,
it is highly recommended. The performance of the heating system
is greatly enhanced when adding an Insulation Wrap. An insulated
system helps to improve draft, minimize condensation and flue
surfaces warm up quickly. This added feature is important for
exterior chimneys.
NOTE: Ensure there is adequate room for both Liner and Wrap.
- When the chimney passes through a floor, ceiling, or other horizontal
or vertical structure, firestops of a non-combustible material must be
used.
- IF THE PROPER CLEARANCES LISTED ABOVE CANNOT BE
DETERMINED THE LINER MUST BE INSTALLED WITH AN APPROVED
INSULATION WRAP.
NOTE: Always wear gloves,
eye protection and
dust respirator.
4.) INSTALLING STAINLESS STEEL FLEXIBLE LINER
- Make sure the thimbles to be used in the installation are in the
proper chimney to maintain the required clearance to combustibles
for the connector pipe from the appliance. If the clearances are not
correct reconstruct the thimble to the proper position.
- Determine the length of the liner by measuring from the bottom of
the opening to the top of the chimney. To this measurement add
approx. six inches to accommodate the crown and top hardware.
Cut liner to length by using a hacksaw, snips or a disc cutter.
The size of the liner selected should be the same size of the appli-
ance flue outlet opening or as specified in the appliance manufactur-
er’s instructions. Correct sizing is critical for venting of low tempera-
ture flue products in geographical areas experiencing sustained low
ambient temperatures. Improper sizing may lead to excessive con-
densation of moisture, creosote build up and poor draft. A certified
technician may alter the size of the liner to suit the appliance within
codes perimeter. Consult the appliance manufacturer for guidance.
