Floor Protection
This appliance requires a non-combustible floor protection to protect against burning embers. If the floor is to be stone, tile,
brick, etc., it must be mortared or grouted to form a continuous, non-combustible surface. If a chimney connector extends
horizontally over the floor, protection must cover the floor under the connector and at least 2" (51 mm) to either side.
The floor protection must extend completely beneath the stove and to the front, sides, and rear as indicated.
USA REQUIREMENTS
16" minimum to the front of the fuel door glass
8" (203 mm) minimum beyond the sides of the fuel door opening
0" minimum to the back of the stove body
CANADA REQUIREMENTS
18" (457 mm) minimum to the front of the fuel door glass
8" (203 mm) minimum beyond the sides of the fuel door opening
8" (203 mm) minimum to the back of the stove body
A floor protector must be installed with an R-value of 1.0 (English units). Use of a listed floor protector is acceptable.
An easy means of determining if a proposed alternate floor protector meets these requirements is to follow this proce-
dure:
1) Convert specification to R-value:
i
R-value is given - no conversion is needed.
ii
k-factor is given with a required thickness (T) in inches: R = 1/k x T
iii C-factor is given: R = 1/C
2) Determine the R-value of the proposed alternate floor protector.
i
Use the formula in step (1) to convert values not expressed as "R".
ii
For multiple layers, add R-values of each layer to determine the overall R-value.
3) If the overall R-value of the system is greater than the R-value of the specified floor protector, the alternate is accept-
able.

The Stromboli and Lascar does need additional floor protection. You hat to use ½" mill-board, which is equivalent
to an R-value of 1.
