Prefabricated Chimneys; Clearances To Combustibles; Floor Protection - Jøtul F 118 CB Installation And Operating Instructions Manual

USA/Canada
A connector pipe must then extend from the stove's flue
exit through the damper area of the fireplace and into the
chimney tile liner. See fig. 10. In any case, we recommend
that a full liner be installed through any masonry chimney
to ensure good performance.
The inside area of the flue liner must not be less than
the area of the stove flue collar and cannot be more than
three times greater than the cross sectional area of the
stove flue collar.
If the chimney liner is too large to accommodate the
stove, an approved relining system must be installed to
resize the flue.
A new sheet metal damper block-off plate must be
installed around the connector pipe at the damper frame
and sealed with the proper sealant (usually High-Temp
Silicone).

3.3 Prefabricated Chimneys

When connecting the Jøtul F 118 to a prefabricated
metal chimney always follow the pipe manufacturer's
instructions and be sure to use the components that are
required. This usually includes a "smoke pipe adapter" that
is secured to the bottom section of the metal chimney and
allows the chimney pipe to be secured to it with two sheet
metal screws. See fig. 11.

4.1 Floor Protection

The Jøtul F 118 includes a bottom heat shield. The stove
must be installed with the bottom heat shield unless the
stove is on a concrete floor poured on earth.
The Jøtul F 118 requires one of the following forms of
hearth protection if not installed directly on concrete
poured on earth:
1) Any UL, ULC, or Warnock Hersey Listed hearth board.
2) Any noncombustible material.
All forms of protection must include a noncombustible
surface extending forward from the glass panel at least
16" for the U.S., or 18" (46cm) for Canada. Protection must
extend 8" (21 cm) from the sides and rear for both the U.S.
and Canada.
This will result in a minimum floor protection of
30 1/2" W x 53" D for the U.S. or 30 1/2" W x 55" D for Canada.
See fig. 10.
In a rear vent installation, the floor protection must
also extend under the stove pipe a minimum of
2" (50 mm) beyond either side of the pipe. See fig.12.
