NOTE: The triangular fire bricks
are siliconed in place for transit. After
initial use the silicon will break down
and they bricks can be removed.
Remove the side baffles by lifting
upand away from the wall prior to
removing triangular bricks
Installing the Floor Protector
1. The oven must be placed on a
non-combustible floor protector
with an R-value of 2.12 or greater.
Figure 2 - R=1/C EXAMPLE:
If the floor protector is 4" brick with a C-factor of 1.25, over 1/2" mineral
board with a "k" factor of 0.29, the total R-value of the system (R
4" brick C = 1.25
1/2" mineral board K = 0.29
R = R + R
total brick
In this example, the R-value is greater than 2.12 required and therefore this floor
protector is a suitable combination that provides the required thermal protection.
In the USA, the floor protector must extend 8" (203 mm) beyond each side
of the flue loading door and 16" (406 mm) to the front. In Canada, the floor
protector must extend 8" (203 mm) beyond each side and the back of the
appliance and 18" (457 mm) to the front. Refer to figure 3.

For multiple layers, add R-values of
each layer to determine the overall
R-value. When manufacturers
provide a k-factor or C-factor for the
material, you will need to convert
these to the R-value.
The following equations can be
used to convert these factors to the
R-value:
• k-factor, is given with a required
thickness (T) in inches: R=1/k x T.
• C-factor, is given:
