HEARTH PAD REQUIREMENTS
The Ovation stoves can be installed with a leg set. Inserts require no legs. All Ovation stoves require
hearth pad protection. A combustible floor in front of the Ovation stove must be covered with tile,
marble, stone or some other non-combustible hearth pad material. FIGURE 9, page 25, illustrate the
fireplace and the hearth pad extension relationship. Page 28 explains the calculations required to
determine if the non-combustible hearth pad material is adequate. WARNING: A hearth pad must be
installed in accordance with national or local building codes. All hearth extensions for Ovation stoves
must have an R-value of 1.5 or greater to ensure proper floor protection. If thermal conductivity (k-
factor) or thermal conductance (C-factor) is used instead of thermal resistance (R factor) then use the
relationships as follows a) k-factor is given with required thickness (T) in inches as R = 1/k x T or b) C-
factor is given as R = 1/C.
