HEARTH REQUIREMENTS AND FLOOR PROTECTION

Install your stove on the following:

‰A non-combustible floor protector that you obtain from your dealer, or any other noncombustible material. A floor protector is any noncombustible surface laid on the floor underneath the stove that extends, 16 inches -US (or 46 cm in Canada) beyond the fuel loading door and 8 inches (20 cm) beyond each side of the cook stove. (See Figure 1) The hearth protection for your Deva 100 must have an R-value of at least 0.89 or be a UL Listed floor protection.

An example of a non-combustible floor protector would be a hearth constructed with a continuous layer of a listed backer board (such as Wonder-Board or Durock) used for ember protection with a tile, brick, slate, or another noon-combustible facing.

determine the overall R-value of the layers.

If the overall R-value of your setup is greater than the R-value of the specified floor protector, then your setup is acceptable.

If venting the unit using the rear exit, floor protection must extend 2" on either side of pipe.

For horizontal chimney connector installations, the floor protection must be installed beneath the connector and 2” beyond each side.

Floor protector’s come with various types of specifications. To convert a floor protector’s specification to an R-value, do one of the following:

•If the R-value is given, use that value— no conversion is needed.

•If a K-factor is given with a required thickness (T) in inches, use this formula: R-value = 1/K x T

•If a C-factor is given, use the formula: R-value = 1/C

To determine the R-value of the proposed alternate floor protector:

•Use either the K-factor or the C-factor formula explained above to convert specifications not expressed as R-values.

•For multiple layers of floor protectors, simply add the R-values of each layer to

CLEARANCES TO COMBUSTIBLES

Please use this section to plan the layout for your stove. Consider clearance of pipe to combustibles and cookstove to combustibles.

You must follow minimum clearances for the Deva 100 cookstove to combustibles such as walls and ceilings. You may reduce the general clearances if installing the stove near Protected Surfaces.
