CLEARANCES TO COMBUSTIBLES

Floor Protection

Floor protection under the F 3 CB woodstove, must be one of the following:

1.Any non combustible material with an insulative R value of 1.1.

2.Any UL, ULC or WH hearth board or prefrabricated non-combustible material.

The bottom heatshield (standard equipment) is required in all installations.

Individual sections of floor protection must be mortared together to prevent sparks from falling through to combustible materials. Any carpeting must be removed from under the floor protection.

In the U.S.and Canada

The F 3 CB must be installed on a non-combustible surface extending a minimum of 18” (460mm) in front of the stove and 8” (200mm) on the remaining sides of the stove (measured from side and back panels).

This will result in a minimum floor protection of

41 D X 39 W See figure 12.

In a rear vent installation the floor protection must also extend under the stove pipe a minimum of 2” (50mm) beyond either side of the pipe.

Clearances to walls and ceilings

The following clearances have been tested to UL and ULC standards and are the minimum clearances specifically established for the Jøtul F 3 CB.

The following charts and diagrams give the required clearances you must maintain when installing the F 3 CB near combustible surfaces.

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 non-combustible 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.

Using Shields to Reduce Clearances

Pipe shields: When using listed pipe shields to reduce the connector clearance to combustibles, it must start 1” above the lowest exposed point of the connect pipe and extend vertically a minimum of 25” above the top surface of the stove.

Double wall pipe: Listed double wall pipe is an acceptable alternative to connector pipe heatshields.

Wall-Mounted Protection: When reducing clearances through the use of wall mounted protection:

In the U.S. refer to NFPA 211, Standard for Chimneys, Fireplaces, Vents and Solid Fuel Burning Appliances, for acceptable materials, proper sizing and construction guidelines.

In Canada, refer to CAN/CSA-B365, Installation Code for Solid-Fuel Burning Appliances and Equipment, also for acceptable materials, proper sizing and construction guidelines.

Stove mounted Rear Heatshield is standard equipment on all F 3 CB woodstoves. NO OTHER STOVE MOUNTED HEAT SHIELD MAY BE USED.
