3.0 Connecting to the
Chimney

3.1 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 of 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.
3.2 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).

3.3 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.

4.0 Clearance to Combustibles

4.1 Floor Protection

The Jøtul F 400 requires one of the following three forms of
hearth protection:
1. Any UL, ULC or WH listed hearth board. (No bottom heat shield
required).
2. Any noncombustible material that has a minimum
R- value of 2.0. (No bottom heat shield required.)
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 16" for U.S (460 mm for Canada) 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.

4.2 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.
"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.

4.3 Using Shields to Reduce Clearances

Chimney Connector Heat Shields: Use only connector heat
shielding listed for use with solid fuel heaters. The connector
heat shield must begin 1" above the lowest exposed point of the
connector pipe and extend vertically a minimum of 25" (640 cm)
above the top surface of the stove.
Double Wall Connector: Listed double wall pipe is an acceptable
alternative to connector pipe heat shields.
Wall-Mounted Protection: When reducing clearances through
the use of wall mounted protection:
(For both U.S. and Canada)
