4.1 Floor Protection
The Jøtul F 55 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 Type 1 hearth board.
2) Any noncombustible material.
No Bottom Heat Shield is required in either case.
In the U.S. floor protection must extend forward from the
door opening at least 16 in. and 8 in. from the sides of the
door opening. Protection must also extend 2 in. under the
chimney connector. This will result in a minimum floor
protector 33” wide x 40 3/4” deep. See fig 9.
In Canada, floor protection must extend 18” from the
front of the stove and 8 in. (460mm) from the sides and
rear. It must also extend 2 in. (51 mm) under the chimney
connector. This results in a floor protector 43 1/2 in. x 50 1/2
in. (110.5 cm. x 128.2 cm.) See fig.10.
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 55.
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 12-13 for clearance requirements and diagrams.
4.3 Using Shields to Reduce Clearances
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:
In the U.S. refer to NFPA 211, Standard for Chimneys, Fireplac-
es, 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.
Notice: Many manufacturers have developed woodstove
accessories that permit clearance reduction. Use only
those accessories that have been tested by an independent
laboratory and carry the laboratory’s testing mark. Be sure
to follow all of the manufacturer’s instructions.
