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
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.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 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
Contact your local building officials about restrictions and installation requirements in your area.
