Hearth Requirements

The PDV20 and SDVR Heaters must be installed on
rigid flooring. When the heater is installed directly on
any combustible surface other than wood flooring, a
metal or wood panel extending the full width and depth
of the unit must be used as the hearth. There are no
other hearth requirements.
