Jotul 3 CB hearth R value for floor ?

[anavant]

I have an old manual for my 3 CB and it does not state the R Value nneded for under the stove. Anyone know this ?

4.0 Clearances to combustibles
Floor protection
Floor protection under the Jøtul F 3, 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 noncombustible
material.
The bottom heatshield (standard equipment) is required
in all installations.
Individual sections of floor protection must be mortared
together t,o prevent sparks from falling through to
combustible materials. Any carpeting must be removed
from under the floor protection.

Thanks ! So, does "4.0 Clearances to combustibles" mean the hearth has to be 4 inches thick?

That is section 4.0 of the manual.

thanks ! Do you have a PDF of this version of the manual ? Is the F3 the same as the 3 CB ?

It is a cut and paste from the manual for the F3CB USA. The stove I have sitting in my basement.

Download a copy of the manual from the Jotul site with this link.

The F3 is not the same as the F3CB, it's the predecessor without the secondary reburn system.
