Connecting to the Chimney
Masonry Chimney
When installing a Jøtul F 400 into a masonry chimney
through a “thimble” (the opening through the chimney wall
to the flue), the thimble must consist of ceramic tile or
steel and be securely cemented in place.
The chimney connector/stove pipe must slide completely
inside the thimble to the inner surface or the flue liner. It
may be necessary to make use of a thimble sleeve (a pipe
with a slightly smaller diameter than standard stove pipe).
See figure 5

.
The connector pipe or thimble sleeve must not protrude
into the flue liner or otherwise restrict draft.
Use refractory cement to seal the seam between the
chimney connector, sleeve, and thimble.
Do not connect this stove to a chimney flue servicing
another appliance of any kind.
Hearthmount into a Masonry
Fireplace
The Jøtul F 400 may be installed into a masonry fireplace
provided the height of the opening is a minimum of 29 1/2”.
Use of the Short Leg Package will reduce the stove height
by 2 1/4” (57 mm).
Building code requires that the fireplace damper plate be
removed or securely fixed in the open position. 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 figure 6.
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).
Prefabricated Chimneys
When connecting the Jøtul F 400 to a prefabricated metal
chimney always follow the pipe manufacture’s instructions
and be sure to use the components that are required. This
usually includes some type of “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 three sheet
metal screws. See figure 7.
Clearance to Combustibles
Floor Protection (For both U.S. and Canada)
The Jøtul F 400 requires
one
of the following three forms
of hearth protection:
1.1.
1.1.
1. Any UL, ULC or WH listed hearth board. (No bottom heat
shield required).
2.2.
2.2.
2. Any noncombustible material that has a minimum
R- value of 2.0. (No bottom heat shield required.)
3.3.
3.3.
3. Any noncombustible material with the use of the stove’s
bottom heat shield.
All forms of protection must include a noncombustible
surface extending a minimum of 18” (460 mm) in front of
the stove, and 8” (200 mm) from the sides and back of the
stove (measured from side and back panels).
This will result in a minimum floor protection of 42”W X
44”D. See figure 8.
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 figure 8

Consult appendix A at the back of this section for alternate
floor protection methods and materials.
Clearances to Walls and Ceilings
The clearances listed and diagramed in this manual have
been tested to UL and ULC standards and are the minimum
clearances to combustible materials specifically
established for the Jøtul F 400 .
A combustible surface is anything that can burn (i.e. sheet
rock, wall paper, wood, fabrics etc.). These surfaces are
not limited to those that are visible and also include
materials that are behind noncombustible materials.
If you are not sure of the combustible nature of a material,
consult your local fire officials.
Remember: “Fire Resistant” materials are considered
combustible; they are difficult to ignite, but will burn. Also
“Fire-rated” sheet rock is also considered combustible.
Contact your local building officials about restrictions and
installation requirements in your area.
See pages 8-9 for complete clearance requirements and
diagrams
