4.0 Clearances to
Combustibles
4.1 Floor Protection
Floor protection under the stove must be a UL 1618 Type I Ember
Protector composed of 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 Jøtul F 500 must be installed on a non-combustible surface
extending:
A minimum of 18" (457mm) 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
54,25"W X 50,5"D.(1378mm x 1283mm) 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.
Alternate hearth protection
A h e a r t h p a d m e a s u r i n g 4 6 " w i d e X 5 0 , 5 " d e e p
(1168mmx1283mm)can be used only if the left side door is locked to
prevent use. Door Lock Kit #155850 is available for this purpose.
4.2 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 500.
The following diagrams give the required clearances you must
maintain when installing the Jøtul F 500 near combustible
surfaces. See pages 17-18.
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. Contact your local building officials about
restrictions and installation requirements in your area.
Remember: " Fire Resistant" materials are considered combustible;
they are difficult to ignite, but will burn. Also "Fire-rated" sheet
rock is also considered combustible.

Using Shields to Reduce Clearances
Pipe shields: When using listed pipe shields to reduce the
connector clearance to combustibles, it must start 1"(25,4mm)
above the lowest exposed point of the connect pipe and extend
vertically a minimum of 25" (635mm) 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 Heatshield: A stove rear heatshield has been
specifically designed for the Jøtul F 500.
Rear heatshield part # 154332.
No other heat shield may be used.
See pages 17-18 for complete clearance requirements and
diagrams.
Notice
Accessories for wood stoves for clearance reduction have been
developed by many manufacturers. If not following the methods
of the installation codes, be sure that any accessory you choose
has been tested by an independent laboratory and carries
the laboratory's testing mark. Make sure to follow all of the
manufacturer's instructions.
Always contact your local building inspector or fire officials
about restriction and requirements in your area. Reminder,
it is the local officials who have final authority for the
installation approval.
4.3 Alcove Installation
The Jøtul F 500 can be installed in an alcove situation provided:
See figures 9 and 10.
1. The stove must be installed with listed double walled pipe.
2. In a protected alcove installation both side walls and rear wall
must be protected per NFPA 211 or CAN/CSA-B365. The wall
protection must be elevated 1"(24,5mm) from the floor and
at least 1" (24,5mm)off the combustible wall to allow for an
air-flow.
3. The height of the wall protection including the bottom air
space must be 48"(1219mm).
4. The bottom heatshield is required in all alcove installations.
5. H e a r t h p r o t e c t i o n m a t e r i a l m u s t c o n s i s t o f :
a) a UL/ULC listed Type II Thermal Floor Protector or,
b) material having a minimum r value of 1.6 (see appendix a).
6. Minimum ceiling height in an unprotected installation, off the
top of the stove is 41"(1041 mm). The minimum ceiling height
off the top of the stove in a protected ceiling installation is
15"(380mm).
Use of the left side load door is prohibited in alcove installations.
