CLEARANCES TO COMBUSTIBLES
Floor Protection
Floor protection under the stove, must be constructed
of a non-combustible material for protection from
radiant heat, sparks, and embers.
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 OSLO F500 must be installed on a non-
combustible surface extending a minimum of 18
(460mm) in front of the stove and the left side load
door (measured from the legs). And 8 (200mm) on
the right side and back of the stove (measured from
side and back panels).
This will result in a minimum floor protection of
54.5W X 49D.
See figure 8.
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.
WHEN CONSTRUCTING A NEW HEARTH OR FLOOR PAD,
CONSULT APPENDIX A AT THE BACK OF THIS MANUAL
FOR ALTERNATE MATERIALS AND METHODS.

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 OSLO F500.
The following diagrams give the required clearances
you must maintain when installing the OSLO F500
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.
SEE PAGES 10-12 FOR COMPLETE
CLEARANCE REQUIREMENTS AND
DIAGRAMS.
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.

HEARTH PROTECTION
FIGURE 8
A hearth pad measuring 46 wide X 53 deep
can be used. HOWEVER, USE OF THE LEFT
SIDE LOAD DOOR IS PROHIBITED when
this size hearth is used; Because access to the
firebox is only allowed through a door that has a
minimum of 18 of hearth protection.
