4.0 Clearances to
Combustibles
4.1 Floor Protection
A bottom heat shield is required in all installations. In
addition, the stove must be placed on a noncombustible
surface that extends 8” beyond the sides and back of the
stove and 16” in the front of the stove. This will result in an
overall base that is 28 1/2” wide x 45- 1/2” deep . This is the
minimum floor protector size. Floor protection must also
be used under the stove pipe and must extend 2” beyond
either side of the pipe (fig. 7, page 13).
The floor protection must have a minimum R value of 0.45.
Warning! Never put any type of floor protection on top
of carpeting.
4.2 Alternate Floor Protection
All floor protection materials must be non-combustible
(i.e., metals, brick, stone, mineral fiber boards, etc.). Any
organic materials (i.e., plastics, wood, paper products, etc.)
are combustible and must not be used. The floor protector
specified may include some form of thermal designation
such as R-value (thermal resistance), k-factor (thermal
conductivity), or C-factor (thermal conductance).
See 8.0 Appendix A on page 17 for the procedure to
determine alternate floor protection materials that meet
the thermal requirements for this stove.
4.3 Clearance to Adjacent Combustible
Materials
The diagrams in figures 8-13, pages 13-14, specify the
required clearances that must be maintained from
unprotected combustible materials or objects.
A combustible material is anything that can burn, and in
the case of stove installations, these material may not be
visible. lf you are not sure of the combustible nature of any
material in the vicinity of your planned stove installation,
you should check with your local fire officials. Remember
that “fire resistant” materials are considered combustible;
they are difficult to ignite, but they will burn.
lf you have recently purchased a home that has a stove
hearth in it that you plan to use, it is extremely important
that the entire system be examined for safety. Many older
homes may have faulty chimneys, or previous owners may
have covered combustible walls or studs with brick veneers.
Heat is conducted readily through brick and could ignite
combustible materials hidden behind it.
Contact local building or fire official about restrictions and
installation requirements in your area.
4.4 Using a Rear Heat Shield to Reduce
Clearance
The Jøtul F 602 CB optional rear heat shield, PN HS50,may
be used only in top-exiting parallel installations to reduce
clearance as shown in figures 11,12,13, page 14.
4.5 Using Wall Protectors to Reduce
Clearances
The wall protector must be non-combustible, such as a
minimum 24 gauge galvanized steel or its equivalent.
The wall protector must be elevated 1” from the floor to
provide an air space of at least 1” between the shield and
the combustible wall. See figures 14-18 on pages 14-15 for
approved sizing specifications.
4.6 Alcove installation
When installed with a listed double wall pipe and with wall
protection, the Jøtul F 602 CB can be placed in an alcove that
has a minimum height of 96”
1
and a maximum depth of 48”,
and a minimum width of 41”. See fig. 14, page 14.
When installed with a listed double wall pipe and with a
stove heat shield, the Jøtul F 602 CB can be placed in an
alcove that has a minimum height of 96”
1
and a maximum
depth of 24”
2
, and a minimum width of 55”. The clearances
for this installation are shown in fig. 13 page 14.
4.6 Alcove wall protection
In an alcove, the height of the wall protector, including the
air space at the bottom, must be at least 41” (104 cm). See
fig. 15, page 16. Both side walls and the rear wall must be
protected by the wall protector. See fig. 15, page 14.
4.7 Fireplace Clearances
For a fireplace installation, refer to the clearance specifications
as shown in fig. 19, page 15.
