hearth extension insulated to a minimum R value of 1.16.

To substitute materials for the factory-available hearth ex-
tensions, see Figure 8.3 and calculate insulation alterna-
tives as per Table 8.1 and the following formulas:

• Thermal conductivity per inch thickness =

k

• k = (BTU)(inch) / (foot

2

)(hour)(°F)

• Required thickness = Rk

• Thermal resistance per inch thickness =

r

• r = (foot

2

)(hour)(°F) / (BTU)(inch)

• Required thickness = R / rB.
